SETUP SENSOR

1.

Open the remote sensor battery compartment with
a small Phillips screwdriver.

2.

Insert the batteries, matching the polarity as shown
in the battery compartment.

3.

Selec any channel.

4.

Place the sensor near the main unit. Press 

RESET

on the sensor. Then, press and hold 

SEARCH 

on

the main unit to initiate signal sending between the
sensor and the main unit. The reception icon on
the main unit will blink for approximately 3 minutes
while it is searching for the sensor. (Refer to the
Data Transmission section for more information.)

5.

Close the remote sensor battery compartment.

6.

Secure the sensor in the desired location using the
wall mount or table stand.

For best results:

• Insert the batteries and select the channel before

you mount the sensor.

• Place the sensor out of direct sunlight and

moisture.

• Do not place the sensor more than 98 feet

(30meters) from the main (indoor) unit.

• Position the sensor so that it faces the main

(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.

• Place the sensor in a location with a clear view

to the sky, away from metallic or electronic
objects.

• Position the sensor close to the main unit during

temperatures may affect battery performance and
signal transmission.

You may need to experiment with various locations to
get the best results.

Standard Alkaline batteries contain signifcant amounts
of water. Because of this they will freeze in low
temperatures of approximately 10ºF. Disposable Lithium
batteries have a much lower threshold for temperature
with an estimated freezing range of below -40ºF. The
Liquid Crystal Display in outdoor thermometers will
remain operational to -20ºF with adequate power.

Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold may
temporarily reduce the effective range between the
sensor and the base station.

If the unit's performance fails due to low temperature,
the unit will resume proper functioning as the
temperature rises to within the normal temperature range
(i.e no permanent damage will occur to the unit due to
low temperatures).
