operation
The transceiver provides Icom Digital Advanced Sys-
tem (IDAS
™
) that meets the 6.25 kHz emission mask
requirements for narrow banding, and increases effi-
ciency of channel allocation and use of spectrum using
the NXDN
™
common air interface.
NOTE:
During the NXDN
™
system operation, BIIS
1200 and MDC 1200 system operations are not us-
able.
You can use a preset operation type in a zone.
Conventional mode
D
The Conventional system enables normal digital mode
channel management by manually selecting a chan-
nel.
Trunking mode
D
The Trunk system enables further effective channel
management by sharing a minimum number of chan-
nels with a large number of users.
NOTE:
While in the Trunking mode, you can receive
and transmit digital calls in the same way as in the
Conventional mode.
