time display.
2. “MIN/MAX”: Allows you to view the

you to change the hours, minutes,
temperature unit, and 12/24 hour
time display.

MULTIPLE REMOTE SENSOR
UNITS” section in the Detailed Set-
Up Guide.
1. Have the indoor weather station and
remote temperature/humidity sensor
3 to 5 feet apart.
2. Batteries should be out of all units
for 15 minutes.
3. Place the batteries into the remote
temperature/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 temperature/humidity sensor
will start to communicate with each
other, and the display will show both the
indoor temperature and an outdoor

7
temperature and humidity. If the indoor
weather station does not display both the
indoor temperature and the outdoor
temperature and humidity after the 15
minutes please re-try the set-up as
shown on page 5.
After both indoor temperature and
outdoor temperature and humidity are
displayed for 15 minutes you can place
your remote temperature/humidity
sensor outdoors and set your time.
Notes on Outdoor Sensor Placement
The remote temperature/humidity sensor
should be placed in a dry, shaded area.
Fog and mist will not harm your remote
temperature/humidity sensor but direct
rain must be avoided.
The remote temperature/humidity sensor
has a range of 330 feet. Any walls that
the signal will have to pass through will

8
reduce the distance of the range. An
outdoor wall or window can have up to
30 feet of resistance and an interior wall
can have up to 20 feet of resistance.
Your distance plus resistance should not
exceed 330 feet in a straight line.
To complete the set up of your indoor
weather station after the 15 minutes
have passed, please follow the steps
below.
1. Press and hold the “SET” button for
5 seconds.
2. The minutes will now be flashing.
a. Press and release the “+”
button until the correct
minutes are shown.
Note: There is “PM” displayed
to the left of the hour when
between noon and midnight.
During the AM hours this area
will be blank.
b. When the correct minutes
are shown, press and

9
release the “SET” button
once.
3. The hour will now be flashing.
Press and release the “+”
button until the correct hour is
displayed.
Press and release the SET button
once more, and you are done.
