I 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.
*Only 2 selectable output powers are available with some
versions. In this case, level 1 stands for 60 W (the same as
level 2).
NOTE: Low power setting affects all channels ex-
cept the 2182 kHz emergency channel.
NOTE: Although power selection appears possi-
ble with GMDSS versions, only high power is
available.
