Transmit frequency check
When "DUP" appears on the display such as for a
ship-to-shore channel, the transmit frequency differs
from the received frequency.
In such a case, the transmit frequency should be
monitored before transmitting to prevent interference
to other stations.

Transmit power selection
The transceiver has 3 selectable output powers.*
High power allows longer distance communications
and low power reduces power consumption.
*Only 2 selectable output powers are available with some
versions. In this case, level 1 stands for 60 W (the same as
level2).
~
NOTE: Low power setting affects all channels ex-
~
cept the 2182 kHz emergency channel.
