What's in this update
- PTT USE WITH DVR: If the KDVR3 menu entry 1 tap option is set to AUTOPTT (the default), then PTT behaves as follows:
- If you start DVR message play first (by tapping M1-M4), then assert PTT during the message, DVR play will be cancelled.
- If you assert PTT first, then play a DVR message, it will play normally, and will complete even if you let go of PTT.
You can also cancel DVR message play by tapping REC, as usual, whether PTT is asserted or not. (Or cancel from a computer using the ÒRX;Ó command see below.) Note: If the KDVR3 menu entry 1 tap option is set to USE PTT, then PTT is required as a qualifier for DVR message play.
In this case, releasing PTT in the middle of a DVR message will cancel it.
Remote Control Command Changes:
- DVR MSG PLAY CANCEL: You can now use the ÒRXÓ command to cleanly cancel DVR message play (as well as any other transmit or message-play function, in any mode).
- CONFIG: DIGOUT1 MENU PARAMETER is now accessible with the ÒMP" command. Values 000 and 001 only; get/set.
