Vertex Standard VX-4100 BASIC OPERATION OF THE TRANSCEIVER

BASIC OPERATION OF THE TRANSCEIVER

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.

Press the (POWER) button to turn the radio on. The display will become

illuminated.

Press the PF (Programmable Function) button which is programmed to the Chan-

nel Up/Down feature to choose the desired operating channel. A channel number

will be displayed. See page 7 for more information on the Programmable Func-

tion keys.

Turn the VOL knob clockwise to increase the volume, and counterclockwise to

decrease it.

To transmit, monitor the channel and make sure it is clear.

THIS IS AN FCC REQUIRMENT!

Press the PF button which is programmed to the Monitor feature 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 BUSY/TX indicator will glow red. The radio is now

transmitting. While holding in the PTT switch, speak across the face of the mi-

crophone in a clear and normal voice. For best transmission, hold the micro-

phone about 1-1/2 to 2 inches away from your mouth. Release the PTT switch to

receive.

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

a short beep three times. Release the PTT switch and wait for the channel to be

clear of activity.

If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on a

channel, the radio can transmit only when there is no carrier being received or

when the carrier being received includes the correct CTCSS tone or DCS code.
