■ Functions for transmit

D Transmit frequency check

When "DUP" appears on the display, such as for a
ship-to-shore channel, the transmit frequency differs
from the receive frequency.
In such cases, the transmit frequency should be mon-
itored before transmitting to prevent interference to
other stations.

D Transmit power selection

The transceiver has 3 selectable output powers.
High power allows longer distance communications
and low power reduces power consumption.
NOTE: Low power setting affects all channels ex-
cept the 2182 kHz emergency channel.
