BATTERY INSTALLATION AND REMOTE

THERMO-SENSOR SETUP

Follow this step-by-step procedure for installing batteries and
setting up the remote-sensor unit. Successful setup should ensure
that temperature signals are properly received.

Note: The effective range may be limited by building
materials and the position of either the main unit or the
r e m o t e   t h e r m o - s e n s o r   u n i t .   T r y   v a r i o u s   s e t - u p
arrangements for best result.

Setting up the thermo-sensor unit:

1. Position the remote sensor within the signal transmission

range of the main display unit. The maximum transmission
range is 100 feet (30 metres).

2. Remove the screws of the battery door on the remote thermo-

sensor unit.

3. Select display of temperature in either °C or °F using the

°C/°F slide switch.

4. Install into the thermo-sensor unit, two UM-3 or "AA" size

1.5V batteries strictly according to the polarities shown.

5. Replace the battery compartment door and secure its screws.

Note: Though the sensor is splash proof and is meant for
use outside, it should be placed away from direct sunlight,
rain, or snow.

Once the batteries have been inserted into the remote thermo-
sensor unit, batteries can now be inserted into the main unit.
