NOTES
1A Normal tone transmit condition.
1B Tone Tx with phase reversed.
2 NOTONE programmed in Tx mode; tone transmit output set to VDD/2 -(0.7v). Tx audio path enabled.
3A Normal decode standby.
3B Normal decode standby with PTL used to enable audio.
4 Normal ‘decode of correct CTCSS tone’ condition; PTL has no effect.
5 NOTONE programmed in Rx mode; tone transmit output (o/c). Rx audio path enabled.
