This version added the following changes 1.

Transmittind Delay drop out timer priority Channel 2.

Transmittind Delay drop out timer non priority Channel 3.

Dwell Time on priority Channel 4.

Dwell Time on non priority Channel 5.

Threshold Parameter Analog 6.

Scanning LED color 10.

Stun and Kill with DTMF Note: In this version, if you keep the Threshold Parameter at 0, the system will lockup with any noise.

This is not an error but predicable with how scanning works.

If Tx Drop Out Delay is set to zero and the system acquires a channel, the system will lock-up.

Don't leave that parameter at zero.

This bug will be fixed in the next version.
