Set-up

Both the Weather Station (receiving unit) and the Remote sensor
(sending unit) require batteries. Insert the batteries in the Weather
Station before doing so for the remote units.
To Install Batteries in your Weather Station
1 Remove the base stand. Press the door tab and slide down the
battery cover on the back of the main unit. Insert 2 AA size
batteries according to the "+" and "-" polarity marks shown in the
battery compartment.
2 The (—) dash icon will flash on the LCD screen. The main unit is
now ready to register with and receive the RF temperature signal
from the remote sensor(s).
Battery Installation for your Wireless Remote Sensor
1 Lift off the bracket stand of the RF remote sensor, then use a
small Philips screwdriver to remove the battery cover screws.
2 Insert 2 AAA size batteries according to the "+" and "-" polarity
marks shown in the battery compartment.
3 Once the batteries are inserted, the sensor will transmit the
temperature signal to the receiving unit at 30 second intervals or
when there is a 0.2°C change in temperature. The sensor is also
equipped with a manual transmission button (TX) located in the
battery compartment. To operate, use a ball point pen or other
pointed tool to press the TX button for 2 seconds.
4 Once the main unit has received the temperature signal, the icon
" 1 " and the temperature of the corresponding sensor will be
displayed on the lower part of the screen.
5 If you have more than one remote sensor, please do not insert
batteries for all remote sensors at the same time. After
registration of the
first sensor is
completed (i.e. the
temperature is
displayed on the
screen), then
insert the batteries
for the second
sensor and
complete registration before proceeding with the third sensor.
NOTE: In order to protect our environment, please dispose the
old batteries promptly and properly. Do not burn or bury them.
Before replacing the back cover, try the test described in the
Operations section of the manual to make sure the two units are
communicating.
For wireless remote sensor with attachable probe only
If measurement of water, soil, or liquid is desired, open the cover of
the plug hole at the side of the sensor and insert the probe plug.
• If the outdoor temperature is extremely low (below 10°C), extend
the 6 foot probe cord outdoors, and keep the remote sensor unit
indoors to avoid freezing up the battery.
• The temperature readings will be displayed on the remote channel
matching the remote sensor where the probe has been inserted.

Troubleshooting

If the display for a particular channel shows a dash (—), check: the
following items:
• The remote unit of that channel is still in place and connected.
• The batteries of both units are fresh. Replace as necessary.
• The transmission is within range and path is clear of obstacles and
interference. Shorten the distance when necessary.
• Avoid signals from other household devices, such as home security
systems and entry controls, that may interfere with this product and
cause temporary reception failure. This is normal and it doesn't affect
the general performance of the product. Temperature transmission
and reception of readings will resume once interference recedes.
The main unit and remote sensor contain no user serviceable parts

Precautions

1. Do not clean the units with abrasive or corrosive compounds. It
may scratch the plastic parts and corrode the electronic circuits.
2. Do not subject the units to excessive force shock, dust,
temperature or humidity, which may result in malfunction, shorter
electronic life span, damaged batteries and distorted parts.
3. Do not tamper with the units' internal components. Doing so will
invalidate the warranty on the unit and may cause unnecessary
damage battery and distorted parts.
4. Do not subject the units to excessive exposure to direct sunlight.
5. Never immerse in water or expose to heavy rain. The remote
sensor is of a splash-proof design.
6. Always read the user's manual before operating the unit.
