Bypassing the Low Transmission Power
Setting
In the USA and Canadian frequency bands, transmissions on
select channels are required to be low-power (1 W) by default,
because they are intended for intership (bridge-to-bridge)
communication ( Switching Between 1 W and 25 W Transmitting
Modes , page 3 ). If other radios cannot receive these channels
due to the low power setting, you can bypass the default
restriction during transmission.
NOTE: In the International channel band, the radio does not
permit transmissions on these select channels to be changed to
high (25 W).
1
From a USA or Canadian channel set to low power by
default, such a 13,17, or 77, select PTT .
2
While transmitting, select 25W .
