When using sequential transmission, the sequence number is set by sections 5-8 of the
address switch. The central transmitter always transmits in sequence 0 (address 00) and
the transmitters that are meant to transmit simultaneously should also have hex 0 as the

System Check
After the system installation, a functional check is made according to the installation guide
for each unit.
Initiate a paging and check that the pocket receiver responds correctly. Repeat this for
every unit that can generate pagings including pocket transceivers. In speech systems
make sure that the voice messages are clear. Check all other functions such as absent
indication, busy tone, mobile-to-mobile calls etc.
Note:
The battery saving time (set in the PUP or PDM depending on handset) must be set
to a battery saving time of 0.5, 2 or 5 seconds. The mode 0 seconds is for handset test
purpose only and is not supported by the system. Keeping the mode 0 seconds during
