M043 P.5 P.6 M043 Receiver stage indicator Interference The RF Temperature signal indicator in the clock's outdoor temperature window will show the following: Signals from other household devices, such as entry controls, door bells and home security systems, may temporarily interfere with the clock and cause reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature reading will resume once the interference has stopped. NO SIGNAL DETECTION SIGNAL DETECTION SUCCESSFUL RECEPTION Using the Stand The remote unit comes with a wall mount holder which can hold the unit on wall, or just place it on a flat surface. Losing Synchronization of the wireless thermometer If the clock displayed a proper outdoor temperature in the past but now displays blank "--", the wireless transmitter and clock may have lost synchronization. If this occurs, press the HR/RE-SYNC button of the clock. The clock will attempt outdoor temperature reception for another 6 minutes and reinitiate synchronization with the wireless transmitter. If the remote temperature cannot be received, check: 1. The distance of the clock or wireless transmitter should be at least 3-4 feet away from any interfering sources such as computer monitors or TV sets. 2. Avoid placing the receiver onto or in the immediate proximity of metal window frames. 3. Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception. 4. Neighbors using electrical devices operation on the 433MHz signal frequency can also cause interference. Note: When the 433MHz signals is received correctly, do not re-open the battery cover of either the wireless transmitter or the clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset both unit (see Getting Started above) otherwise transmission problems may occur. The maximum transmission range is 100 feet from the wireless transmitter to the clock (in open space). However, this depends on the surrounding environment and interference levels. The temperature signal travels in a straight line from the transmitter to the clock. The signal will not curve around blocking object. Each will or floor the signal must pass through is equal to approximately 20 feet of open space. If no reception is possible despite the observation of these factors, all system units have to be reset ( see Getting Started ). Trouble-Shooting • Press the "Reset" button when the clock is displaying irrelevant temperature reading. This may happen when external noise is severe enough to interfere with the RF temperature signal. • Press the "Reset" button on the wireless transmitter if the readout is irrelevant or does not repond. Care of your clock • Avoid exposing your clock to extreme temperatures, water or severe shock. • Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents. • Do not subject the clock to excessive force, shock, dust, temperature or humidity. Any of these conditions may shorten the life of the clock. • Do not tamper with any of the internal components of this clock. This will invalidate the warranty and may cause damage. P.7 M043 Correct usage of the batteries • Use 4 new "AA" batteries • Do not mix standard of rechargeable batteries • Do not mix new and old batteries • When the low battery mark " " appears on the display, replace the appropriate batteries with new ones.
