4 Speak into the handset.
NOTE: Five minutes is the maximum time allowed for transmission. After five minutes of transmitting, PTT
is disabled until you release PTT.
5 Release PTT.
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 9). 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.
