Getting Started Upon power up of the remote unit ( or pressing the reset button ), the temperature RF signal is immediately sent to the main unit. The main unit attempts to receive the RF temperature signal for 5 minutes. The main unit refreshes the RF temperature every 3 minutes. Check IN / REMOTE Temperature The indoor temperature is displayed on the IN temperature field and the remote temperature will be displayed on the REMOTE temperature field. If the RF temperature signal is not received within 5 minutes after power up of the main unit (or pressing the reset button), blank "---" will appear in the outdoor temperature window of the main unit. In this case, press the HR/SYNC button of the main unit. The main unit will attempt outdoor temperature reception for another 6 minutes. After the remote temperature shows in the lower LCD panel, place the remote unit outside in a shaded, dry area to protect it as if under an umbrella. Try relocating the unit if the main unit does not display the remote temperature after 6 minutes. Maximum and Minimum IN / REMOTE Temperature The maximum and minimum recorded temperature readings will automatically be stored in the memory. Press the Max/Min button once to display the indoor maximum and minimum record. Press the button again to show the REMOTE maximum and minimum record. The respective indicators, IN and REMOTE will be displayed. To clear the memory, press CLEAR when the maximum and minimum temperature records are shown, it will clear the record of the shown temperature field. P.4 M059 Clock Set 1.

Whatever the display unit of the remote unit is, it will be automatically converted to the chosen one of the main unit. M059 P.5 P.6 M059 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 units and cause reception failure. This is normal and does not affect the general performance of the units. 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 main unit equipped with a flip stand, you can use the stand to place the main unit on flat surface, or flip the stand back and hang the main unit on wall with the wall mount holder. Losing Synchronization of the wireless thermometer If the main unit displayed a proper outdoor temperature in the past but now displays blank "-", the units may have lost synchronization. If this occurs, press the HR/RE-SYNC button of the main unit. The main unit will attempt outdoor temperature reception for another 6 minutes and reinitiate synchronization with the remote unit. If the remote temperature cannot be received, check: 1. The distance of the units should be at least 3-4 feet away from any interfering sources such as computer monitors or TV sets. 2. Avoid placing the main unit 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. Perspective view from front and right side Perspective view from front and right side The remote unit comes with a wall mount holder which can hold the unit on wall, or just place it on a flat surface with the flip stand. Note: When the 433MHz signals is received correctly, do not re-open the battery cover of either the units, 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 remote unit to the main unit (in open space). However, this depends on the surrounding environment and interference levels. The temperature signal travels in a straight line from the remote unit to the main unit. The signal will not curve around blocking object. If no reception is possible despite the observation of these factors, all system units have to be reset (see Getting Started). Perspective view from front and right side Perspective view from front and left side Trouble-Shooting • Press the "Reset" button when the unit 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 respond. P.7 M059 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. 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.
