If there is still no communication, please perform the
following steps:
• Bring the main unit and remote sensor close together.
• Remove four (4) small screws from the back of the
remote sensor with a small Phillips screwdriver, and
open the battery compartment.
• Remove the batteries from the battery compartment
and reinstall them in the same manner. Remote sensor
LED indicator will flash showing transmission of the
signal.
• Remove the batteries from the main unit and reinstall
them in the same manner.
• The remote temperature appearing on the main unit’s
display will show that the transmission is being
received successfully.
TRANSMISSION COLLISION
Signals from other household devices such as wireless
doorbells, home security systems, and entry control
may interfere with this product or cause temporary
reception interruption. This is normal and will not affect
the general performance of the product. The
transmission and reception of the temperature readings
will resume once the interference subsides.
PRECAUTIONS
This product is engineered to give you years of satisfactory
service if handled carefully. Here are a few precautions:
• Do not immerse the units in water.
• Do not clean the units with abrasive or corrosive
materials. They may scratch the plastic parts and
corrode the electronic circuits.
• Do not subject the product to excessive force, shock,
dust, temperature, or humidity, which may result in
malfunctions, shorter lifespan, damaged batteries, and
damaged parts.
• Do not tamper with the units internal components.
Doing so will invalidate the warranty and may cause
damage. These units contain no user-serviceable parts.
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 reading line of the main unit
warning that the corresponding batteries need replacement.
The Unit is in searching mode
Temperature readings are
securely registered
No signals detected.

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
The remote temperature information is
located on the larger section of the
main unit’s display.
The wave icon is located above the
remote channel number and indicates
the reception status from the remote
sensor.
There are three types of reception
status that may be displayed:
The indoor temperature with the icon IN is located
next to the remote temperature information section.
NOTE: If the indoor or remote temperature goes above
or below operating range stated in specifications, the
main unit’s display will show dashes “- - -”
MAXIMUM AND MINIMUM READINGS
The maximum and minimum record of the indoor and
remote temperatures will be automatically stored in
the memory of the main unit (receiver).
To display the minimum, maximum
or the current reading, press the
MEM button.
If no button is pressed for the next 15 seconds, the
unit will return to the current temperature display.
To clear the memory, press and hold the MEM button
for two seconds and all previously stored readings
will be erased.
LOST COMMUNICATION
If the main unit display line for the remote sensor
reading goes blank, press and hold the SEARCH
button for 2 seconds to begin a new signal search.
If the signal still isn’t received, please make sure that:
• The remote sensor is in its proper location.
• The distance between main unit and remote sensor
is not over 100 feet (30meters).
• The path between units is clear of obstacles. Shorten
the distance if necessary.
• Fresh batteries are installed correctly in both remote
sensor and main unit.
