NOTE ON WHERE TO PLACE THE UNIT

This unit is designed for outdoor usage.

When the unit is relocated from one place to another in
extreme temperatures (

e.g.

 from a very hot area to a very

cold one), water condensation may occur on the lens at
the front. This will not affect the functions of the unit. In
this case, leave the unit in the same location for 2-3 hours
and the water condensation will disappear.

The temperature sensor is located at the top of the unit.
When the unit is placed under direct sunlight, the accuracy
of the temperature display may be affected.

TIP

It is suggested to put the unit under shade from

direct sunlight.

TEMPERATURE DISPLAY

After battery installation, the unit immediately reads and
displays the surrounding  temperature.
