does not appear).
- Channel is busy.
- No matched (or matched) CTCSS is received.
- The selected channel is a ‘receive only’ channel.
• Time-out timer
After continuous transmission for a pre-programmed period,

transmitting and automatically select receive.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
