Boosting the transmission power
In most situations, the 1 Watt transmission power is all you need. If you find yourself far
away from other stations and have trouble getting a response, you may need to boost the
transmission power from 1 Watt to 25 Watts:
1. Select the channel you want to transmit on.
2. Push and hold
ENT-1W/25W
for two seconds. The display shows 25 Watts in the upper left
hand corner.
3. The transmit power remains at 25 Watts until you change the setting back. Push and
hold
ENT-1W/25W
for two seconds. The display shows 1 Watt.
#
nOte: Don’t forget to change the transmission setting back to 1 Watt when you move closer
to other stations.
#
nOte: By default, when you change to channel 16, the radio automatically boosts the
power to 25 Watts. Be sure to change the power back to 1 Watt if you are not making an
emergency transmission.
Some channels (for example, channels 13 and 67) limit the power of transmission to 1 Watt
so that there is less interference between boaters attempting to use the channel at the same
time. If you switch to one of these channels, the radio changes back to 1 Watt automatically.
See the channel lists beginning on page 37 for a list of power-restricted channels.
Choosing triple Watch or Dual Watch
In Triple Watch mode, the radio briefly checks channels 16 and 9 every two seconds. In Dual
Watch mode, the radio checks channel 16 only. Generally, Triple Watch is used in areas
where channel 9 is used as a hailing frequency while Dual Watch is used in areas where
channel 16 is used for distress and hailing. Your radio comes set to use Triple Watch; if you
want to use Dual Watch instead, you will have to select it in the setup:
1. Press and hold
CALL MENU
to display the normal menu.
2. Select Setup and then Dual/Tri Watch.
