As a part of FCC procedures and marine communications courtesy, initial contact should always be attempted using low power. You should switch to high power only when contact can not be made on low power in emergency situations.
Note: Some channels are limited by regulation to be low power only. If the HILO operation request is denied, an error tone beeps.
Overriding the Low Output Power Restriction
In the US, channels 13 and 67 can temporarily override the low power restriction.
➤To override the LO power restriction on
channels 13 or 67 and transmit at high power:
Press and hold the PTT key on the microphone as you press and hold the HI/LO key. The TX power is set to HI power for as long as you hold down the HI/LO key.
