If the transmitter zone number appears during Transmitter Sniffer mode but does not clear, it could be because the transmitter zone type (ZT) is set to 00 (Not Used); set ZT to a valid active zone type in field,56. It could also be due to the transmitter battery not being installed; install the proper battery. Finally, the 5800 system transmitter may not be enrolled in the system; enroll the unit in field,56.
