■
IDAS operation
The IC-F5120D and IC-F6120D series use the Icom Digital
Advanced System (IDAS) that meets the 6.25 kHz emission
mask requirements for narrow banding. IDAS increases ef-
ficiency of channel allocation and use of the RF spectrum.
NOTE:
During IDAS operation, MDC 1200 system opera-
tion capability is disabled.
■
IDAS Trunk operation
The IDAS Trunk system enables further effective channel
management by sharing a minimum of channels with a large
number of users.
Push [Zone], then push [CH Up] or [CH Down]* to select the
IDAS Trunk zone.
* The method to select the desired zones may differ, depending on
your system set up.
NOTE:
During IDAS Trunk operation, you can receive and
transmit digital calls in the same way as IDAS operation,
as described in ‘

Receiving a call,’ ‘
