J11 on the CPU board is the connector for system configuration jumpers.
Move the jumper at pins 5 and 6 to pins 4 and 5 to enable the CPU to
recognize optional relays mounted on the power supply board. Later units
will be shipped with the jumper already at pins 4 and 5, even if the relay
option is not purchased.
Move the jumper to pins 1 and 8 of the J11 connector to erase system
memory.
Caution
Placing a jumper across pins 1 and 8 on the J11 connector erases
system memory. All user-entered parameters are erased and reset to factory
defaults.

If you are going to erase memory by placing a jumper across pins 1 and 8,
first remove power from the detector-transmitter. Note the location of the
jumpers on the J11 connector. Place a jumper across pins 1 and 8, apply
power, and leave power on for approximately 30 seconds to erase memory.
Remove power and restore the configuration jumpers to their original
settings.
