pears.

NOTE: Channel busy
When channel 70 is busy, the
all ships call is not transmit-
ted. The transceiver waits
until the channel is clear, then
transmits the call automati-
cally.
NOTE: Error indication
When a transmission inhibited
channel (e.g. ch 70) is se-
lected for the traffic channel,
the display at right appears. In this case, an appropriate
channel must be selected.
This display may also appear if [9•ALL/IND] is accidentally
released early while being pushed and held in step ➂.
