Your radio’s other features include:
• Channel Scan — use to find other
GMRS/FRS users.
• Key Beep — each time you press
a key, except PTT or FUNC, the
radio beeps once.
• Voice Operated Transmission
(VOX) — enables standalone
usage and works with handsfree
accessories.
• Automatic Power Off — you can
set the amount of time before the
radio automatically turns itself off
when it is idle (30, 60 or 90
minutes).
• Hi/Lo Power Selection — select
0.5W or 1.0W transmit power for a
GMRS channel.
• Courtesy Tone — at the end of
transmission, the radio receiving a
transmission sounds a tone to
confirm the end of the
transmission.
• Direct Call — you can select the
radio you want to hear your
transmission. Only that radio
receives a call you address to it
and displays the transmitter’s
number identifying your radio on its
display.
