Some marine channels and Weather mode channels are Receive Only. See
page 28 for a list of receive-only channels.
There is a 5 minute limit for continuous transmission. After 5
minutes the unit goes into a PTT error condition; the timeout
tone sounds, TX displays, and the channel indicators blink.
Boosting the transmission power
In most situations, 1W 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 1W to 2.5W or 6W.
Alkaline battery boost is limited to 2.5W
Channels 75 and 76 are 1W only and do not have power override
capability.
1) Select the channel you want to transmit on.
2) Press
L/M/H to switch to the next transmission power level (for example,
from 1W to 2.5W; from 2.5W to 6W, or from 6W back to 1W).
3) The display shows the new transmission power. The transmit power re-
mains at the new setting until you change it again.
Don’t forget to change the transmission setting back to 1W when
you move close to other stations.

Some channels (for example, channels 13 and 67) limit the transmission
power to 1W. When you tune to a limitedpower channel, the radio automati-
cally switches to 1W. See page 28 for a list of power-restricted channels.
