2.3.4 Master Code Switch
The master code switch MUST be kept in the OFF position for normal operation. Turn the master code
switch ON when programming the system’s master code. See section 3.1.1 to program the system’s master
code. If the master code switch is turned ON and a new master code is NOT entered, the system will sound
a long tone after approximately 30 seconds. This tone will continue every 30 seconds until a new master
code is entered, or until the switch is turned off. After the switch is turned off, the LCD display will remain lit
for approximately 30 seconds, and then will turn off.
Note: Master code switch is turned ON when adjusting the LCD display, see section 2.3.3 for more
information.
