Click on a flourish to return to the top of the page Sage Advice of the Utmost Importance 1) Install the Barometric Prognosticator III unit on a wall inside a dwelling out of direct sunlight, as the lenses on the front panel could focus direct sunlight sufficiently to cause a fire. 2) Do not manually turn the Readings Display Disc as this will damage the Disc Drive Engine. 3) Only connect the Barometric Prognosticator III to a source of power when it is vertical. Do not instigate operation unless it is in a vertical position. 4) No user serviceable parts within, contact the purveyor if the Barometric Prognosticator III stops functioning in the correct manner. 5) Keep out of the reach of small children as they could choke on small parts, get their fingers trapped in moving parts or wreak havoc on the Barometric Prognosticator III. 6) Only connect to the supplied USB power supply or one rated to at least 1.25 amperes. 7) Keep the illuminating lamp directed at the unit and do not cover it with anything as it gets hot.   8) Use the supplied screws or similar with appropriate fixings for the type of wall to which the Barometric Prognosticator III is being fixed. 9) The wireless monitor should be placed outside in a position sheltered from rain or direct sunlight. 10) Disconnect the source of power if your intention is to be absent for a few days. 11) Ensure air is free to flow around the provided USB power source otherwise it could get too hot. Installation of your  Barometric Prognosticator III The Barometric Prognosticator III should be installed inside a dry dwelling on a vertical wall away from direct sunlight. It hangs on the two supplied screws. It is recommended to be installed at a height where the Exterior Readings lens is at eye level. See illustration above for dimensions. 1) Firmly grasping the Barometric Prognosticator III’s left and right side panels, offer it up to the wall to the desired position. 2) Get a companion to make a small pencil mark upon the wall just above the top side panel behind the lamp support exit. 3) Return the Barometric Prognosticator III to a flat surface, resting on its back. 4) Make a small pencil mark 69mm down the wall from the original mark. 5) Employ a spirit level to horizontally extend the lower mark out equally to the left and right by 222.5mm. 6) If your wall is constructed from wood, ensure it is sound, and carefully screw each of the two supplied supporting screws into the wall at each end of the horizontal line. Stop tightening at the point where 7mm of each screw remains protruding. 7) If, however, your wall is constructed from brick or some other drillable material, drill a suitable hole at each end of this horizontal line using an appropriate drill and drill bit. Insert the appropriate type of wall plug into each hole, tapping with a hammer until flush with the surface of the wall. Screw the supplied supporting screws into the wall plugs. Stop tightening at the point where 7mm of each screw remains protruding. 8) Firmly grasping the Barometric Prognosticator III’s left and right side panels, offer it up to the supporting screws. It is often easier to locate one screw first, moving the Barometric Prognosticator III around slightly until you feel it settle against the wall as the screw enters the keyhole hanger. Allow that end of the unit to drop down slightly and check it cannot pull away from the wall. Now raise or lower the other end of the unit until you feel the second screw properly seat inside its keyhole hanger. Removing Support Packaging The flute operating chain will be fixed to its pulley with packaging material to prevent damage during transit. Remove the packaging and ensure the chain lies properly over the pulleys as shown in the diagram. The flute bellows will also be held closed with packaging and this too needs to be removed. The bellows can be checked by gently lifting the bottom section up to produce a note. Installing the exterior weather monitoring device Find a suitable position outside for the Exterior Weather Monitoring Device. It must be sheltered from rain and direct sunlight. If it does not already contain a power source inside the sliding cover on its reverse, please insert one. An operating lamp on the front of the Exterior Weather Monitoring Device should then begin flashing twice a minute. This indicates normal operation. If the readings displayed by the Barometric Prognosticator III cease to change from day to day, the exterior weather monitoring device’s battery has probably gone flat. Replace this, and the Barometric Prognosticator III should begin displaying current readings. The switch beside the battery selects one of three channels it can use to transmit information. It would only be worth changing this setting in the unlikely event a neighbour had a wireless device working on an identical channel. The instructions on the rear suggest using the rest button when the battery has been replaced, although this doesn’t seem to be necessary. Having a Pleasant Cup of Tea Make a wholesome cup of tea and stand back and admire your Barometric Prognosticator III. Upon First Connection of the Main Power Source Once the Exterior Weather Monitoring Device has been installed and the Barometric Prognosticator III is fixed to a wall, the supplied Main Power Source can be connected. The Barometric Prognosticator III will respond by playing a short rendition of the National Anthem. It will then search for a signal from the Exterior Weather Monitoring Device. Once detected, a second rendition of the National Anthem with be played. At this stage the barometric pressure, exterior humidity and exterior temperature can be displayed by turning the Preference Valve (see below). Requesting an immediate musical rendition of weather readings, will, however, result in a uninspiring melody unworthy of the Barometric Prognosticator III. This is due to the availability of an insufficient number of weather readings to allow proper composition. Proper compositions will become available after an hour or so. Clock Movement Power Source The clock runs off its own power source which can be accessed via a recess in the back panel. If the clock ceases to function, the power source can be replaced. As the Barometric Prognosticator III cannot stand upright by itself and because of the risk of damage if it falls over, it is recommended that two people undertake this task. 1) Disconnect the main power source from the Barometric Prognosticator III. Holding it on the left and right, lift it off the wall fixings. 2) Rest it on a flat surface, on either its left or right hand side - not on the top or bottom as this could damage the lamp or cable. 3) From the rear of the unit, the second person can achieve release of the old power source from the rear of the clock by gently pulling the ribbon. 4) Once a new power source has been correctly inserted, the clock hands will begin moving after a few seconds. 5) The Barometric Prognosticator III can be carefully rehung on its wall supports. 6) Check the flute chain is aligned with the pulley and reconnect the main power source. Setting the Clock Movement If the clock already shows the correct time this section can be skipped. The clock receives a time signal from a central clock housed in the National Physical Laboratory in Anthorn, Cumbria. This should ensure the time displayed is correct throughout the year without the need to adjust the clock to account for Daylight Saving. If, however, the clock does not display the correct time due to poor reception, it can be set manually. Due to the risk of damaging the Barometric Prognosticator III, it is strongly advised that this activity is undertaken by two persons. 1) Repeat steps one and two above. 2) Depress one of the buttons on the rear of the clock movement to set the time. The recommended button is M.SET as you can manually set the correct time and the clock will continue to search for the time signal. The buttons function as follows: M.SET - This button manually sets the clock if it cannot detect the time signal. Hold the button down and the hands will start moving after a few seconds. Release the button once the correct time is shown. The clock will act as a normal quartz clock until it detects the time signal. RESET - Push and hold the button for three seconds. The hands will move to the twelve o’clock position and remain there until the time signal is detected. It is a good idea to leave the clock over night. as the reception can improve at night. Nothing will happen if there is no reception. REC - Push and hold the button for three seconds. This will function as RESET above, except if there is no reception, the clock will display the last shown time. 3) Repeat steps five and six above. Employing the Preference Valve The Preference Valve allows you to control how the Barometric Prognosticator III operates. The valve responds differently when turned to the left or right. Generally turning to the left allows the hourly tune to play, whilst turning to the right causes silent operation. The number of clicks the valve is turned sets the weather reading dial to show either pressure, humidity or temperature. After the valve has stopped being turned, the bell or flute will sound to acknowledge a setting has been changed. The valve legend acts as a reminder to the following settings. tEn clickS Turning to the right sets the optional hourly tune to be created from the last twenty four hours of pressure readings alone. Turning to the left sets the tune to include three sections based on pressure, humidity and temperature changes. One to Four clickS Regardless of the number of clicks, turning to the right cancels the hourly tune. The bell sounds once to acknowledge this. Turning the the left sets the hourly tune to play. The flute plays a note to acknowledge the change. See below for each count. One Click The flute sounds once and the Readings Display Disc moves to indicate the pressure twenty four hours ago. Over a period of eight seconds it then maps the pressure changes up until the present time, when the flute again sounds once. Two Clicks The flute sounds twice and the Readings Display Disc moves to indicate the humidity twenty four hours ago. Over a period of eight seconds it then maps the humidity changes up until the present time, when the flute again sounds twice. Three Clicks The flute sounds three times and the Readings Display Disc moves to indicate the external temperature twenty four hours ago. Over a period of eight seconds it then maps the temperature changes up until the present time, when the flute again sounds three times. Four Clicks The Barometric Prognosticator III immediately plays the selected historical weather tune on the bell and flute (just pressure or pressure, humidity and temperature). Right and left turns function as above. Musical Rendition of Historical Weather Readings When selected to do so, the Barometric Prognosticator III will play a melodic rendition of the weather readings taken over the previous twenty four hours. The rendition consists of three parts: 1) The bell will chime once indicating barometric pressure readings. Eight notes will be played by the flute. These are derived from historical readings expanded mathematically to fill the available range of notes. 2) The bell will chime twice indicating relative humidity readings. Eight notes will be played, again expanded mathematically to fill the available range of notes. 3) The bell will chime three times and then eight notes representing exterior temperature readings will be played. The rendition will allow you to create a mental picture of the weather trends over the previous twenty four hours and this will allow you to more accurately make a weather prediction. Cleaning Wipe gently with a dry soft cloth. Do not use cleaning agents as they may damage the painted or varnished surfaces. Using a soft brush attachment for a vacuum cleaner works well at removing dust. Alternatively, a vacuum cleaner hose can be held carefully near individual components, and the dust can be loosened using a soft paintbrush. Just ensure the vacuum hose doesn’t hit any of the components, as it could damage the finish. Improper Functioning If your Barometric Prognosticator III seems not be displaying weather readings as you have come to expect, remove the USB power supply from its socket. Wait a few seconds and then re-connect it. This will cause previous weather readings to be lost, but may well solve the issue.
