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.
Push and hold [TX FREQ] to monitor the transmit fre-
quency.
The display shows the transmit frequency.

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.
Push [FUNC] then [TX] to call up the following dis-
play.
Rotate the [CHANNEL] selector to select high or
low output power.
3 : high power (150 W PEP)
2 : middle power (60 W PEP)
1 : low power (20 W PEP)
Push [FUNC] or [CE] to return to the previous dis-
play.
