Preliminary Steps
Ì Install a charged battery pack onto the transceiver, as
described previously.
Ì Screw the supplied antenna onto the Antenna jack.
Never attempt to operate this transceiver without an
antenna connected.
Ì If you have a Speaker/Microphone, we recommend that
it not be connected until you are familiar with the ba-
sic operation of the VX-410/-420.
Operation Quick Start
Ì Turn the top panel’s VOL/
PWR knob clockwise to turn
on the radio on.
Ì Turn the top panel’s CH selec-
tor knob to choose the desired
operating channel.
Ì Rotate the VOL/PWR knob to
set the volume level. If no sig-
nal is present, press and hold
in the Soft key assigned to
“MONITOR” for more than 1
seconds; background noise will
now be heard, and you may use this to set the VOL/
PWR knob for the desired audio level.
Ì Press and hold in the Soft key
assigned to “MONITOR” for
more than 1 seconds (or press
the MONITOR key twice) to
quiet the noise and resume nor-
mal (quiet) monitoring.
Ì To transmit, monitor the chan-
nel and make sure it is clear.
THIS IS AN FCC REQUIRMENT!
Ì To transmit, press and hold in
the PTT switch. Speak into the
microphone area of the front
panel grille (lower left-hand
corner) in a normal voice level. To return to the Re-
ceive mode, release the PTT switch.
Ì If a Speaker/Microphone is available, remove the plas-
tic cap and its two mounting screws from the right side
of the transceiver, then insert the plug from the Speaker/
Microphone into the MIC/SP jack; secure the plug us-
ing the screws supplied with the Speaker/Microphone.
Hold the speaker grille up next to your ear while re-
ceiving. To transmit, press the PTT switch on the
Speaker/Microphone, just as you would on the main
transceiver’s body.
Note:Save the original plastic cap and its mounting
screws. They should be re-installed when not us-
ing the Speaker/Microphone.
