Section III — Indoor-Remote
Thermometer
DISPLAY OF INDOOR TEMPERATURE
Once batteries are installed into the main unit, it will start to detect
the indoor temperature and the data will be displayed.
HOW TO CHECK REMOTE
TEMPERATURE
Once batteries are installed into the remote Thermo Sensor, it will
start to transmit temperature data at an approximately 40-second
intervals. Such data transmission is indicated by the blinking LED
on the remote Thermo Sensor. Upon successful reception of the
remote thermo signals the data received will be automatically
displayed and updated at a 40-second intervals.
To toggle between indoor and remote temperature display, press
[IN/OUT TEMP].
If no signals are received, blank "—-" will be displayed. Press and
hold [IN/OUT TEMP] for 2 seconds to activate search for the
remote thermo signal from the sensor. (Note: during this searching
period, reception of clock radio signal will be suspended)
If that fails, check if the remote thermo sensor is still in place. Try
repositioning the units as they may be having temperature
transmission block as a result of interference.
Note: Failure of reception of remote signals may be due to the
following reasons:
1. Battery power of the units is too low.
Suggested Solution: Replace with fresh batteries if necessary.
2. Batteries may freeze when the temperature falls below the
freezing point. Frozen batteries will have a lower voltage and
therefore result in a shorter transmission range.
Suggested Solution: Shorten the transmission range by
repositioning the units.
