VX-920/-970 SERIES OPERATING MANUAL

 If a Speaker/Microphone is available, remove the

plastic cap and its two mounting screws from the

right side of the transceiver, then align the con-

nector of the Speaker/Microphone on the trans-

ceiver body; secure the connector pin using the

screws 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, and speak into the mi-

crophone on a normal voice level.

Note 1): Save the original plastic cap and its

mounting screws. They should be reinstalled

when not using the Speaker/Microphone.

2) When you press the PTT switch on the

Speaker/Microphone, it disables the internal

microphone, and vice versa.

 If the Busy Channel Lockout feature has been

programmed on a channel, the radio will not trans-

mit when a carrier is present. Instead, the radio

will generate short beep three times and indicate

“

ERROR

” on the display (16-key and 4-

key versions). Release the PTT switch and wait

for the channel to be clear of activity.

 If CTCSS or Digital Coded Squelch (DCS) Lock-

out has been programmed on a channel, the radio

can transmit only when there is no carrier being

received or when the carrier being received in-

cludes the correct CTCSS tone or DCS code.

Automatic Time-Out Timer

If the selected channel has been programmed for

automatic time-out, you must limit the length of each

transmission. While transmitting, a beep will sound

10 seconds before time-out. Another beep will sound

just before the deadline; the “TX” indicator will dis-

appear and transmission will cease soon thereafter.

To resume transmitting, you must release the PTT

switch and wait for the “penalty timer” to expire.
