QUICK SETUP
Hint: Use good quality Alkaline Batteries
and avoid rechargeable batteries.
1. Have the indoor weather station and
remote temp/humidity sensor 3 to 5 feet
apart.
2. Batteries should be out of all units for
10 minutes.
3. Place the batteries into the remote
temp/humidity sensor first, then into
the indoor weather station.
(All remote temp/humidity sensors
must be started before the indoor
weather station)
4. DO NOT PRESS ANY BUTTONS
FOR 15 MINUTES.
In this time the indoor weather station and
remote temp/humidity sensor will start to
talk to each other and the displays will show
both the indoor temperature and an outdoor
temperature and humidity. If the indoor

6
weather station does not display both the
indoor temperature and the outdoor
temperature and humidity after the 15
minutes please retry the set up as shown on
page five.
After both indoor temperature and outdoor
temperature and humidity are displayed for
10 minutes you can place your remote
temp/humidity sensor outdoors and set your
time.
Notes on Outdoor Sensor Placement
The remote temp/humidity sensor should be
placed in a dry, shaded area. Fog and mist
will not harm your remote temp/humidity
sensor but direct rain must be avoided.
The remote temp/humidity 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 can
have up to 30 feet of resistance and an

7
interior wall can have up to 20 feet of
resistance. Your distance plus resistance
should not exceed 330 ft. in a straight line.
To complete the set up of your indoor
weather stations after the 10 minutes have
passed, please follow the steps below.
1. Press and hold the “SET” button for
two seconds.
2. The minutes will now be flashing.
a. Press and release the “+”
button until the correct
minutes are showing.
b. When the correct minutes are
shown, press and release the
“SET” button once.
3. The hours will now be flashing.
a. Press and release the “+”
button until the correct hour
is displayed.
Note: There is “PM” displayed to
the left of the hour when between
noon and midnight. During the

8
Battery
compartment
AM hours this area will be blank.
Press and release the SET button three
more times and your time is set.
NOTE: There is also a setting for the
temperature measuring unit and 12/24-
hour time. Please see the detailed set-up
section for more details on these settings.
