Turn off Close Call by pressing the squelch knob until no icon appears in the upper right corner of your display. If you want to use the menu go to Menu>Close Call> Off.
I turned CC on and then pulled the power cord and plugged it in again and CC are then off. I.E. it doesn't store that setting, along with most others, to the SD card until you properly power off the scanner and it says "writing to SD card".
Are you turning the scanner off gracefully? (Turning power/vol knob to the off position so scanner can write changes to SD card rather than cutting power abruptly)
Yes, as /Ubbe has stated, any changes you make will NOT be saved on the SD card until the scanner is shut down using the normal recommended method while power is still supplied to the scanner. It will allow the changes to be saved. I have mine hooked up to the accessory side of the ignition switch which will divorce power when the vehicle is turned off and come back on when the vehicle is started. It’s not a problem unless you use the record option, in which case you could corrupt the SD card. I have never had a problem powering the scanner in this manner but I don’t bother with the record option.
