QUICK SETUP
Hint: Use good quality Alkaline Batteries; avoid rechargeable batteries.
1. Have the Wireless Temperature Station and temperature sensor 3 to 5 feet
apart.
2. Batteries should be out of both units for 5 minutes.
3. Place the batteries into the Temperature sensor first and next into the
Wireless Temperature Station.
4. DO NOT PRESS ANY BUTTONS FOR 5 MINUTES.
In this time the Wireless Temperature Station and the temperature sensor will begin
to communicate with each other, and the display will show both the indoor
temperature and an outdoor temperature. If the Wireless Temperature Station does
not display both temperatures after the 5 minutes, please retry the set up as stated
above. After both indoor and outdoor temperatures are displayed for 5 minutes you
can place your temperature sensor outdoors, and set your time.
The temperature sensor should be placed in a dry, shaded area (ex: under the eve
of a roof). The temperature sensor has a range of 330 feet. Any walls that the
signal will have to pass through will reduce distance. An outdoor wall or window will
have up to 20 feet of resistance and an interior wall will have up to 10 feet of
resistance. Your distance plus resistance should not exceed 330 feet in a straight
line.

NOTE: Fog and mist will not harm your temperature sensor, but direct rain must be
avoided.
DETAILED SETUP GUIDE
BATTERY INSTALLATION - When one Temperature sensor is being used
1. First, insert the batteries to the Temperature sensor (see “Temperature
sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the
Temperature Station (see “Wireless Temperature station” below). Once the
batteries are in place, all segments of the LCD will light up briefly. Following
the indoor temperature and the time as 12:00 will be displayed. If they are
not shown in LCD after 60 seconds, remove the batteries and wait for at least
60 seconds before reinserting them. Once the indoor data is displayed user
may proceed to the next step.
3. After the batteries are inserted, the Temperature Station will start receiving
data signal from the sensor. The outdoor temperature should then be
displayed on the Temperature Station. If this does not happen after 2
minutes, the batteries will need to be removed from both units and reset from
step 1 and the signal reception icon is no longer shown.

TEMPERATURE SENSOR
1. Remove the Battery Cover.
2. Observing the correct polarity, install 2 “AA”
Alkaline Batteries—make sure they do not spring
free, or start-up problems may occur.
3. Replace the Battery Cover.
WIRELESS TEMPERATURE STATION
Note: After the batteries are installed, DO NOT press any buttons. This may
interfere with the signals, causing temperatures to register incorrectly.

•*When the signal is successfully received by the Temperature Station, the
icon will be switched on. (If not successful, the icon will not be shown in LCD)
So the user can easily see whether the last reception was successful (icon
on) or not (icon off). On the other hand, the short blinking of the icon shows
that a reception is currently taking place.
•If the signal reception is not successful on the first frequency (915MHz) for
45 seconds, the frequency is changed to 920MHz and the learning is tried
another 45 seconds. If still not successful the reception is tried for 45
seconds on 910MHz. This will also be done for re-synchronization.
SELECTING 12 OR 24 HOUR TIME DISPLAY
1. Press and hold the set/ch button for about 5 seconds.
2. “12h” will begin to flash in the TIME section of the LCD
3. Press the min/max/+ button to toggle between “12h” and “24h” time.
Note:
•Selecting 12 hour time will automatically select °F as your temperature unit.
•Selecting 24 hour time will automatically select °C as your temperature unit.
4. Press and release the set/ch button again to enter Time Setting.
