Changing channel
Different jurisdictions in the world have allocated different sets
of VHF radio channels for different purposes. These sets are
known as channel banks. The available channel banks and their
corresponding channels are given in “Appendix 11 - US and ROW
VHF marine channel charts” on page 111.
You can switch the RS90 to any channel that is available in your
geographic area. Normally the radio is left tuned to the priority
channel (CH16 or CH09) in case an emergency call is broadcast on
that channel. The RS90 can also be set to monitor several channels
at the same time. In this case, the radio continuously scans the
selected channels and, if activity is heard on a channel, it will switch
to that channel while the activity continues. Then it will revert to
scanning. See “Scanning channels” on page 31.
You can use one of the following methods to change channel:
• Press [16/9] to switch immediately to the priority channel (see
“Priority channels” below).
• Press ▲ or ▼ until you reach the required channel number.
