at 3 minutes intervals Upon successful reception. the remote unit temperature will
be displayed on the Remote tempeiature field. The main unit will automatically
update the remote reading at 3 minutes intervals.
ll no signals are received within the 5 minutes intervals. blank -, ' will be
displayed.
Check IN I 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 no reading are received for five consecutive times, blank "- -" will be displayed
on REMOTE field. In this case, pressing Bl RE_SYNC button will force the maln
unit to receive signals lor 6 minutes ( Refer to Lose Sync. )
Maximum and Minimum Ianemote Temperature
The maximum and minimum recorded temperature readings will automatically be
stored in the memory.
To display the maximum and m mum temperature, press TEMP MAX/MIN once
to display the in maximum and mum tempemture and again the Remote
maximum and minimum temperature. 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.
Centlgrade ( -c l or Fahrenheit ( 'F ) set

Signals from other household devices, such as entry controls, door bells and home
security systems. may interfere the RF Thermometer to cause lemporanly
reception failure. This is normal and does not afiect the general perlDrmanDe of the
product. The transmission and reception ol temperature reading will resume once
the interference stopped,
