Note: RCS's will not usually read the same temperature as they do above.
This is due to variants such as drafts and handling. This is normal.
1. Install the batteries in sequential order. Observe the correct polarity
and install 2 AAA batteries. The batteries will fit tightly-make sure they
do not spring free. This may cause start-up problems.
2. Check the LCD screen of the RCS for a temperature reading. If there is
no reading check the polarity of the batteries or replace with new

7. The Indoor Temperature Station should now show "-:—" in the TIME
LCD, and temperatures in the INDOOR and OUTDOOR LCD'S.
II. MOUNTING
Note: The sending range of the RCS is 80 ft. However, obstacles such as
walls, concrete, and large metal objects can reduce the range. Before
permanently mounting, place units in their desired location to see if a reading
is obtained. There should be a change of temperature in the OUTDOOR

Temperature Station.
5. Replace battery cover.

from the RCS, it will display the last temperature reading for 15 minutes.
After 15 minutes of not receiving any signals the OUTDOOR LCD of the
Indoor Temperature Station will display "- - . -". Also, ensure that the probe
can reach the desired location before mounting.
The RCS can be mounted in two ways:
• with the use of screws or,
• using the adhesive tape.
5. Snap the RCS into place, and situate the probe. It may be necessary to
further secure the probe and wire, to prevent drifting.
B. MOUNTING WITH ADHESIVE TAPE
1. With a nonabrasive solution, clean and dry the back of the mounting
bracket and the mounting surface to ensure a secure hold. The mounting
surface should be smooth and flat.
2. Remove the protective strip from one side of the tape. Press firmly into
2. Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents, they may mark the displays and casings.
3. Do not submerge in water.
4. Do not subject the units to unnecessary heat or cold by placing them in
the oven or freezer.
5. Opening the casings invalidates the warranty. Do not try to repair the
