Operation
Preliminary Steps
・ Install a charged battery pack onto the transceiver, as described previously.
・ Screw the supplied antenna onto the Antenna jack. Never attempt to operate this
transceiver without an antenna connected.
・ If you have a Speaker/Microphone, we recommend that it not be connected until you are
familiar with the basic operation of the VX-417/427.
Operation Quick Start
・ To turn the top panel’s [VOL/PWR] knob clockwise to turn on the radio on.
・ Turn the top panel’s [CH] selector knob to choose the desired operating channel.
・ Rotate the [VOL/PWR] knob to set the volume level. If no signal is present, press and
hold the [MONOTOR] (need select by the key config on program) key 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.
・ Press and hold the [MONITOR] key more than 1 seconds (or press the [MONITOR] key
twice) to quiet the noise and resume normal (quiet) monitoring.
・ To transmit, press and hold the [PTT] switch. Speak into the microphone area of the front
panel grill (lower left-hand corner) in a normal voice level. To return to the Receive mode,
release the [PTT] switch.
・ If a Speaker/Microphone is available, remove the plastic cap and its two mounting screws
from the right side of the transceiver, than insert the plug from the Speaker/Microphone
into the [MIC/SP] jack; secure the plug using the screw supplied with the
Speaker/Microphone. Hold the speaker grille up next to your ear while receiving. 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 using the Speaker/Microphone.
