1.
Plug the AC adaptor into the DC jack of the clock.
2.
Remove the battery door on the bottom of the clock and insert 3 new AA batteries, according
to the polarity information marked on the battery compartment, and replace the battery door.
3.
Once the batteries are inserted, all of the LCD segments will light up briefly before entering
the sensor search mode.
4.
Once the wireless transmitter has synced up to the clock, you can place the sensor outside.
Note:
If no display is present after powering up the clock, press the reset button on the back of the
clock with an open ended paper clip or sharp tool.

Siting the Wireless Transmitter Outside
It is recommended you place the remote sensor in a shaded area.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve. Do not place in
standing water or snow.
Wireless signals are impacted by distance, interference (other wireless devices, wireless phones,
wireless routers, TVs and computer monitors), and transmission barriers, such as walls. In general,
wireless signals will not penetrate solid metal and earth (down a hill, for example).
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
Medium
RF Signal Strength Reduction
Glass (untreated)
5-15%
Plastics
10-15%
Wood
10-40%
Brick
10-40%
Concrete
40-80%
Metal
90-100%
