QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor weather station and remote temperature/humidity
sensor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature/humidity sensor first
then into the indoor weather station.
(All outdoor remotes must be started before the indoor 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 talk to each other and the display will show the indoor temperature and
humidity. If the indoor weather station does not display all information after the 15
minutes please retry the set up as stated above. After all information has been
displayed for 15 minutes you can place your sensor outdoors and set your time.
The remote temperature/humidity sensor should be placed in a dry, shaded area. The
remote temperature/humidity sensor has a range of 80 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 interior wall can have up to 20 feet of resistance.
Your distance plus resistance should not exceed 80 ft. in a straight line.
Note: Fog and mist will not harm your remote temperature/humidity sensor but
direct rain must be avoided.
Note: The remote temperature/humidity sensor transmits a signal every minute.
After the batteries have been installed, the indoor weather station will search for the
signal for a duration of 15 minutes. If there is no temperature and humidity reading
in the TEMPERATURE/HUMIDITY LCD after 15 minutes, make sure the units are
within range of each other, or repeat the battery installation procedure. If a button is
pressed before the indoor weather station receives the temperature/humidity signal,
you will need to follow the battery installation procedure again.
To complete the set up of your wireless weather station after the 15 minutes have
passed please follow the steps that follow in the Detailed Set-Up Guide.
