In most cases, an “out of synchronization” condition indicates that an unauthorized
attempt at grabbing the transmission has occurred – i.e. a previous transmission has been
recorded and sent by somebody trying to violate the system.
The second utility, TX Test, enables you to identify transmitters and test their
signal strength.
In TX Test mode, each time a transmission is received, the activated transmitter
is displayed.
If you enter this function using the Master code, a
chime is sounded every time a transmission is
received. If you enter this function using the
Installer code, a sequence of tones are sounded
indicating the transmitter’s signal strength –
see
Table 4.2.
This feature helps you to determine the
best location to install a transmitter.
To initiate TX Test mode:

3. When you have finished, press
