Before You Begin
To ensure proper functioning of the RF Thermo Clock, please follow this set up
procedure.
- Insert batteries for main unit (Refer to instructions for battery installation ).
- Place the main unit as close as possible next to the remote unit and insert batteries
for the remote unit.
- Position the remote unit and main unit within effective transmission range, which
in usual circumstances is 20 to 30 meters.
Note that the effective range is affected by the building materials and where the main
and remote unit are positioned. Try various setup for best result.
Batteries Installation
Batteries installation of main unit
- Open the battery cover of the main unit.
- Insert 2 pcs of AA size batteries in proper polarity (+) and (-) as indicated.
- Close the battery cover.
Batteries installation of remote unit
° Slide open the battery compartment door.
- Insert 2 pas of AA size batteries in proper polarity (+) and (—) as indicated.
- Close the battery cover.

Getting Started
Once batteries are placed in the main unit, it will start receive signal for 5 minutes,
also once batteries are placed in the remote unit, it will start to transmit information at
3 minutes intervals. Upon successful reception, the remote unit temperature will be
displayed on the Remote temperature field. The main unit will automatically update
the remote reading at 3 minutes intervals.
If no signals are received within the 5 minutes intervals, blank “- -“ will be displayed.
Check IN / 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 of RE_SYNC button will force the main unit to
receive signals for 6 minutes ( Refer to Lose Sync. )
Clock Set
At the back of the RF Thermo Clock, slide the switch to TIME SET and the time will
keep flashing on the display. Then press HR or MIN button to set your desired time
and slide the switch to the LOCK position to complete the time set.

- The transmission is within range and path is clear of obstacles and interference.
Shorten the distance when necessary.
Interference
Signals from other household devices, such as entry controls, door bells and home
security systems, may interfere the RF Thermo Clock to cause temporarily reception
failure. This is normal and does not afl’ect the general performance of the product. The
transmission and reception of temperature reading will resume once the interference
stopped,
Using the Stand
The main unit has a stand which can support the main unit on a flat surface.
