Advantage of DET
It enables DCS squelch operation even in poorer signal conditions.
Disadvantage of DET
When it is activated, suppose 2 stations are sharing the same channel and using the
DCS selective-calling technique and transmitting at the same time. After station A
with its corresponding DCS is gone, you may still hear station B even his DCS code is
different from A, although he can't open your DCS squelch by his signal alone.
To Manually Transmit DTMF Tones
1. Press the numeric, alphabetic or symbol keys while holding down the PTT key.
The tones sound as long as the key is pressed.
2. Up to 16 characters of manually transmitted DTMF tones are automatically stored
for redialing. Refer to "Redial" (page 41) for operation.
