Also,

If you have lost the outside temperature on the clock display after replacing the transmitter battery then do the following:

1. Make sure you have good batteries installed in the remote transmitter
2. Remove the batteries from the main clock and keep them out until the clock display disappers.
3. Re-install the batteries in the clock.
4. Wait until the display returns and includes the outside temperature display as well.
5. Set the clock again for current time/date etc.
6. Bingo. You are in business.

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.

Hi Walter,

I found this in the manual, simply pressing the RESET button won't start communication again. Try this:

Your main unit displays current, minimum, and
maximum temperature and humidity readings
collected by the remote sensor and main unit.
Outdoor data is collected and displayed every
40 seconds and indoor data is collected and
displayed every 10 seconds.

The red LED flashes whenever the sensor
transmits an RF signal to the receiver.
select sensor or use auto scan

• Press CHANNEL to switch between
sensors 1-3.
• To auto-scan between sensors, press and hold
CHANNEL for 2 seconds. Each sensor's data
will be displayed for 3 seconds. To end autoscan,
press CHANNEL or MEMORY.
• Press and hold CHANNEL and MEMORY
simultaneously to search for remote sensors.
resetting the system
The RESET buttons are located on the back of the
main unit and sensor. Use a pointed subject to
press RESET when you change the batteries and
whenever the system malfunctions.
