WIRELESS TRANSMISSION
Environmental factors and signals from other household devices, such
as remote entry controls, security systems, and computers, may
interfere with the wireless transmission of this product and cause
temporary reception loss. This is normal and does not affect the general
performance of this product. Stable reception will resume once the
interference ends.
For optimal performance:
Place the receiver and remote transmitter side by side about 1 metre
apart, and allow the receiver and remote transmitter to synchronize
for 10 minutes before you place the remote transmitter outdoors.
The remote transmitter should be placed in a dry shaded area.
NOTE: Fog and mist will not harm the remote transmitter but
direct rain must be avoided.
Mount the remote transmitter upright avoiding metallic objects
and frames, such as window sills. Verify that there are no obstacles
like a transmission tower or steep hill that can cause interference
and blockage between the remote transmitter and receiver.
CLOCK SETTING
Press HOUR to set the hour.
Press MIN to set the minute.
Press ALARM/(°C/°F) during clock setting to
change between 12 and 24 hour display.
Press MODE or no key press for one minute
will end clock setting.

Press and hold MODE for 3 seconds to enter the Clock Setting mode.

DAY/NIGHT ICON
The day/night icon will change automatically depending on the time of day.
Scroll to the Alarm mode using MODE . The AL symbol will appear.
SOLUTION
The temperature data on the remote transmitter
does not match the data displayed on the
receiver.
This may occur when you move the remote transmitter from one
environment to another. For example, when you bring the
transmitter from inside the warm house out to the cold exterior. In
such a case, there will be a big change in temperature. The
transmitter will record this change in temperature much quicker
than it is able to transmit the data to the receiver (which is done
once every minute). Therefore, you will temporarily get a
difference in reading between the remote transmitter and receiver.
The solution is to allow the remote transmitter some time to sit in
its new location to reach equilibrium. This may take several
minutes. Once the data is stable, the data displayed on the
remote transmitter should match that displayed on the receiver.
The temperature data on the remote transmitter
does not match the data displayed on the
receiver.
This may also be the result of a temporary loss of reception due
to interfering sources. Normal reception should resume once
the interference ends. Refer to the WIRELESS TRANSMISSION
section.
The remote (outdoor) readout on the receiver is
blinking.
Re-synchronize the remote transmitter and receiver by pressing
and holding CHN on the receiver for 3 seconds until a beep is
heard. The temperature data from the remote transmitter will
display on the receiver within 3 minutes. Refer to the WIRELESS
TRANSMISSION (Manual Learn Function) section.
The remote (outdoor) readout on the receiver is
blinking. The receiver will not detect or receive
the temperature data from the remote transmitter,
even after the Manual Learn Function has been
executed.
Ensure the remote transmitter is away from any possible source of
interference and electrical disturbances. You may try to reposition
the remote transmitter in a different location and/or closer to the
receiver. The remote transmitter does have a maximum range of
40 metres, but any walls or windows the signal has to pass through
will reduce the distance. Due to the nature of the batteries,
extreme cold temperatures may also affect the transmission range.
Refer to the WIRELESS TRANSMISSION section and repeat the
Manual Learn Function with the remote transmitter in a new
location.
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.
OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS:
1. THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND
2. THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED,
INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION.
