Do not remove/install the Speaker/Micro-

phone in a hazardous location.

If the Busy Channel Lockout feature has been pro-

grammed 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

“

CH Busy

” 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 au-

tomatic 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 “

” 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.
