    Dwell Time on non priority Channel 5.

    Threshold Parameter Analog 6.

    Threshold Parameter Digital 7.

    Beep Preference 8.

    Analog Promiscous Mode 9.

    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 s​et 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.
