Important!
- Before turning on the radio the first time, confirm that the power con-
nections have been made correctly and that a proper antenna is connected to the
antenna jack.
Switching Power ON/OFF
Press and hold in the
PWR
( ) button for 2 seconds to turn the radio on. The
display will become illuminated.
Press the [
q
]/[
p
] key to choose the desired operating channel. A channel
number will appear on the display.
If you want to select an operating channel from a different group, press the
[
P4
] key repeatedly to select the group you want before selecting the operat-
ing channel. A group number will appear at the upper right corner of the LCD
whenever the [
P4
] key is pressed.
Setting the Volume
Turn the
VOL
knob clockwise to increase the volume, and counterclockwise
to decrease it.
Transmitting
To transmit, monitor the channel and make sure it is clear.
Press the Programmable Function key which is assigned to the “Monitor” fea-
ture to listen for channel activity.
When receiving a call, transmit only after the incoming call ends. The radio
cannot receive a call and transmit simultaneously.
Press the
PTT
switch.
If the channel is clear, the
TX/BUSY
indicator will glow red. The radio is now
transmitting. While holding in the
PTT
switch, speak across the face of the
microphone in a clear and normal voice. For best transmission, hold the mi-
crophone about 4 to 5 cm away from your mouth. Release the
PTT
switch to
receive.
The
VX-4600CB
has a Time-Out Timer which limits the length of each trans-
mission to 3 minutes. It prevent prolonged transmissions.
While transmitting, a beep will sound 10 seconds before time-out. Another
beep will sound just before the deadline; the red “
TX
” indicator will disap-
pear and transmission will cease soon thereafter, and the “
TIME OUT
” will
be indicated on the display. To resume transmitting, you must release the
PTT
switch and wait for the “penalty timer” to expire (if you press the
PTT
switch
before this timer expires, the timer restarts, and you will have to wait another
“penalty” period).
