NOTES:
1. A1KΩresistor installed in RRX J 401 (Pin 4 to Pin 7), turns OFF the RRX internal CTCSS/ QC encoder when
RRX-CGI, pin 12 is connected as shown. DO NOT set R 423 to 0 (zero). (Thisdoes not disable the DQC encoder.)
2. If PJ 404 is left in "A" position, either unplugging the RRX-GCI cable, OR lifting the ORG/BLK wire from GND, will
automatically revert an RRX Repeater to normal (QC) Repeater mode, as programmed. When it is re-connected,
the QC encoder will again be automatically disabled (i.e.: no RESET required).
3. Leave RRX potentiometers at factory settings. Verify/ set R 426 (VOICE DEV pot), reduced to 4.0/ 1.7kHz voice
deviation limiting to allow for 1.0/0.8 kHz of LTRdatadeviation.
