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.
Battery Installation for your Weather Station
To install batteries in the Weather Station:
1. Remove the stand (if it is in place).
Press and slide the battery cover to
open it.
2. Insert 2 AA size batteries, matching the
(+) and (-) polarity marks on the battery
compartment. Close the battery cover
and re-install the stand.
3. A dash icon (—) will flash on the upper
part of the LCD. This indicates that the
unit is waiting and ready to receive a
signal from the remote sensor(s).
Battery Installation for your Wireless Remote Sensor
To install batteries in the Remote Sensor:
1. Lift off the bracket stand by releasing the two bottom
fixing snaps.
2. Use a small Phillips screwdriver to remove the screw
on the battery cover.
3. Insert 2 AAA
size batteries,
matching the
polarity marks
on the battery
compartment.
4. Once the batteries are inserted, the sensor will
automatically transmit a temperature reading at 30-
second intervals to the receiving unit. You can
manually send a signal by pressing and holding the
"TX" button for 2 seconds. Use the tip of a ballpoint
pen, a paper clip or other small pointed implement to
press the TX button.
5. The receiving unit will display a reading for remote
channel 1 and the temperature reading. Before closing
the battery compartment proceed with testing the units
for communication. Instructions for testing are located
in the Operations section of this manual, on the other
side of this paper. Follow the same procedure to install
batteries in other remote sensors.

Troubleshooting
/C and "-" button
o o
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
• 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.
