Before You Begin
• We recommend using alkaline batteries for the remote
sensor and main units when the temperatures are above
0 ˚C (32 ˚F). We recommend using lithium batteries for
the remote sensor when the temperatures are below
0 ˚C (32 ˚F).
• Avoid using rechargeable batteries. (Rechargeable
batteries cannot maintain correct power requirements).
• ALWAYS install batteries in the remote sensor before
the main unit.
• Insert batteries before first use, matching the polarity in
the battery compartment.
• Press RESET after each battery change with a paper clip
or similar tool.
• Remove protective plastic screen from LCD display (if any).
• During initial setup, place the main unit close to the
remote sensor.
• After reception is established (the remote temperature
will appear on the main unit’s display), position the
remote sensor and the main unit within the effective
transmission range of 60 meters (200 feet).
• The remote sensor can be placed indoors or outdoors,
depending on the area where the temperature is
intended to be measured. If you intend to measure
outdoor conditions place the remote sensor outdoors.
• The main unit must always be placed indoors.
NOTE:
1. Avoid pressing any buttons on the main unit before the
remote reading are displayed.
2. The effective operating range may be influenced by the
surrounding building materials and how the receiver and
transmitter are positioned.
3. Place the remote sensor so that it faces the main unit
(receiver), minimizing obstructions such as doors, walls
and furniture.
4. Though the remote sensors are weather-resistant, they
should be placed away from direct sunlight, rain or snow.
The optimal location for the remote sensor outdoors is
under the eaves on the north side of the building.

Battery Installation
NOTE: When the temperature falls below freezing,
the batteries in the outdoor remote sensor may have
reduced voltage supply and a shorter effective range.
We recommend using lithium batteries at temperatures
of 0˚C (32˚F) and below.
REMOTE SENSOR
NOTE: Install the batteries; select the channel
and temperature display reading in ˚C or ˚F before
mounting the remote sensor.
• Remove the screws from the battery compartment with a
small Phillips screwdriver (not included).
• Set the channel. The switch is located in the battery
compartment. Channel 1 is typically selected if only one
remote sensor is being used.
• Set the desired temperature format (˚C or ˚F) using a
pointed pin.
• Install 2 “AA” size alkaline batteries (not included),
matching the polarities shown in the battery
compartment.
• Replace the battery compartment door and secure the
screws.
• Secure the remote sensor in the desired location.
MAIN UNIT
• Remove the battery compartment door.
• Install 2 “AA” 1.5V alkaline batteries (not included) and
matching the polarity as shown in the battery compartment.
• Replace the battery compartment door.

Low Battery Warning
A low-battery indicator [ ] will appear next to the indoor
or remote data reading line, of the main unit, warning that
the corresponding batteries need replacement.
Getting Started
TEMPERATURE DISPLAY
Once the batteries have been installed, the remote sensor
will transmit temperature data at 45 second intervals. The
main unit may take up to two minutes to receive the initial
readings. Upon successful reception, the remote temperature
will appear on the top line of the main unit’s display (the
default remote channel is channel one). The main unit will
automatically update readings at 45 second intervals.
Once communication between the main unit and remote
sensor has been established, secure the remote sensor
in the desired location.
If no signal is received from the remote sensor within two
minutes, dashes [---] will be displayed. Press and hold the
DOWN ( ) button on the main unit for two seconds to
initiate another signal search.
Placement of the Units
The main unit can be placed on any flat surface indoors.
The remote sensor can be placed indoors or outdoors,
on a flat surface or mounted on the wall.
