Safety • Never subject the outdoor sensor to tempera- tures outside the specified range, extensive sunlight, or rain. • Never mix old and new batteries or alkaline and rechargeable batteries. • Remove the batteries if the product is not to be used for a long time. Old batteries can begin to leak and damage the product. • Remember to always insert the batteries according to the markings in the battery com- partment. The wrong polarity (+/-) can dam- age the weather station. • Damage that has occurred by careless han- dling is not covered by the guarantee. • The product must not be modified in any way. Synchronising the sensor with the weather station Before starting: The units should be placed near to one another to ensure a successful synchronisation (when the outdoor temperatu re appears on the display the synchronisation has been successful). Once synchronised, the sensor and weather station can be placed in their intended locations within functional range. 1. Pr ess +/CHANNEL on the weather station one or more times to select channel 2 (CH2). 2. Hold in +/CHANNEL until starts to flash, the weather station will now start to search for a sensor on channel 2. 3. Remove the battery cover of the sensor, set the channel selector to position 2 and then insert two batteries according to the polarity markings. Replace the battery cover. 4. The temperature and humidity readings fr om sensor 2 will now be shown at the same time as the CH2 symbol. If no readings ar e shown on channel 2, you must reset and repeat the synchronisation procedure: Pr ess RESET on the fr ont of sensor once. 5. Repeat the above procedure for sensor 3 if required. 1 2 3 4 1. LED indicator 2. Reset 3. Battery cover 4. Channel selector TW003
