BEFORE YOU BEGIN Battery Pack Installation and Removal To install the battery, hold the transceiver with your left hand, so your palm is over the speaker and your thumb is on the top of the belt clip. Carefully mate the battery’s four insertion slots with their corresponding alignment tabs on the transceiver case, while tilting the Belt Clip outward. Proper alignment occurs with the battery pack offset about 1/2 inch from the top edge of the battery compartment.
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-820. Operation Quick Start Turn the top panel’s VOL/PWR knob clockwise to turn the radio on.
OPERATION Rotate the VOL/PWR knob to set the volume level. If no signal is present, press and hold in the MONITOR button (under the PTT switch) more than 2 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 button more than 2 seconds (or press the MONITOR button twice) to quiet the noise and resume normal (quiet) monitoring. To transmit, monitor the channel and make sure it is clear.
OPERATION If the Busy Channel Lockout feature has been programmed on a channel, the radio will not transmit when a carrier is present. Instead, the radio will generate short beep three times and indicate “* ERROR *” on the display. Release the PTT switch and wait for the channel to be clear of activity.
