NOTE:
1. Avoid pressing any buttons on the main unit before the remote
temperature is displayed for about 2 minutes.
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.
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 32°F (0°C) and below.
BATTERY INSTALLATION
REMOTE SENSOR
NOTE: Install the batteries; select the channel and temperature in
C° or F° before mounting the remote sensor.
• Remove the screws from the battery compartment with a small
Phillips screwdriver.
• Set the channel. The switch is located in the battery
compartment. Channel 1 is typically selected if only one remote
sensor is being used.
• 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
• Open the battery compartment door.
• Install 2 batteries (UM-3 or “AA” size 1.5V) matching the
polarity as shown in the battery compartment.
• Replace the battery compartment door.
LOW BATTERY WARNING
A low-battery indicator [ ] will appear on the indoor or remote
temperature and humidity reading line of the main unit warning that the
corresponding batteries need replacement.
GETTING STARTED
After batteries are installed; remote sensor will transmit temperature
readings at 45 second intervals. The main unit may take up to two
minutes to receive the initial readings. Upon successful reception,
remote temperature will appear on the larger section of the main unit’s
display (the default remote channel is channel one). The main unit will
automatically update readings at 45-second intervals.
If no signal is received from the remote sensor within two minutes,
dashes [- - -] will be displayed. Press and hold the SEARCH button on
the main unit for two seconds to initiate another signal search.
CHECKING REMOTE AND INDOOR TEMPERATURE AND
HUMIDITY
The default display shows the indoor temperature and humidity
information (temperature is on the top, and humidity is on the bottom
line).The IN icon indicates that the unit is displaying the indoor
readings.
