West Marine VHF580 manual Boosting the transmission power, Choosing Triple Watch or Dual Watch

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/25Wfor 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/25Wfor 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 41 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:
