DIP Switch Labels
This device is packed with tear-off DIP switch labels you can attach to the receiver and indicate which DIP switches are on and
off.

switches matching S2 and S3 DIP switches on receiver.
TESTING FOR SIGNAL
STRENGTH
When the receiver is powered and batteries are placed in the
wall module, communication will begin automatically within 2
seconds. The receiver RF signal light will flash every 30
seconds to confirm each transmission. You can force
immediate communication by pressing the signal strength
button on the side of the wall module with a 1-1.6 mm
diameter probe with flat or rounded face (a common paperclip
will do) (see Fig. 9). This may be required to initiate
communication when replacing a wall module.
The signal strength LED next to the signal strength button will
light up on the side to show the relative signal strength. The
signal strength LED will initially light amber when the signal
strength button is pressed to verify that you are pressing the
signal strength button. When you release the signal strength
button, the light will behave as shown in Table 1.
