Main Unit Batteries: On the back of the unit, remove the battery compartment cover.
Insert 2 AAA alkaline (or lithium) batteries making sure they are installed according to the
correct polarity (+/-). Replace the cover.
Wireless Sensor
Main Unit
Wireless Sensor
This water resistant wireless sensor is intended for outdoor use. When deciding where to
place the sensor, make sure it will be protected from direct sunlight and from precipitation.
Do not drop the remote sensor. It is sensitive, and not designed to withstand high impact
blows.
Wireless Sensor Batteries: On the back of the wireless sensor unit, remove the battery
compartment cover. Insert 2 AAA alkaline (or lithium) batteries making sure they are
installed according to the correct polarity (+/-). Replace the cover.
You may need to wait a few minutes after batteries are installed for the units to communi-
cate with each other. When they do, both the indoor and outdoor temperatures will be
shown on the main unit LCD display. If nothing is displayed, refer to section 4 of this
manual for troubleshooting.
NOTE: The sensor’s LED flashes momentarily whenever it sends information – about once
each minute.
Placement & Mounting
Choose a location for each unit that is at least 10 feet away from other electronic devices
that may interfere with the wireless signal. When you decide on a good location, (A steady
signal from the sensor is being received by the main unit LCD display), hang the main unit
and wireless sensor using the triangular indents found on the backs of the units. You may
also choose to place the main unit on a table-top surface using the included fold-out
stand.

for the OUT display.
Main Unit LCD display is
blank. The main unit does
not display any readings
Main Unit LCD display is
operating erratically
Wireless Sensor Unit is
operating erratically
a. Wireless sensor is located too far from the main
unit, move the sensor closer to the main unit.
b. Sensor batteries may need replacing, replace
batteries according to instructions in this manual.
NOTE:After replacing remote sensor batteries, you must
press the RESET button on the LCD display unit.
Follow section 3 of this instruction booklet and
replace the batteries in the main unit.
The main unit may be affected by electrical interfer-
ence. Press the RESET button on the main unit. This
should give you the indoor temperature immediately
and the outdoor temperature within one minute.
The sensor may be affected by electrical interference.
Press the RESET button on the remote sensor.
(located inside the battery compartment between the
batteries.) If the RESET button is pressed, you then
also must press the RESET button on the Main units.
You may also need to relocate all units away from any
electronic interference to restore normal operation.
PROBLEM SOLUTION
Main Unit
The Main unit is intended for indoor use only. When deciding where to put the main unit,
choose a dry location away from dust, dirt, mold and smoke, and avoid temperature
extremes. Do not drop the main unit. It is a sensitive electronic device, and is not designed
to withstand high impact blows.
NOTE: Install batteries in the MAIN UNIT before putting batteries in the wireless
sensor.
