8.3.10 Menu 10 DTMF First Digit Burst Time
It often happens that the radios fail to receive the very beginning instant of each
communication due to squelch/TSQ/DCS etc. By setting the burst time of the first
digit longer, the risk to miss the first DTMF tone will decrease.
1. DB-60 is displayed on the LCD.
2. Rotate the dial to select the initial-character burst time.
