Second attempt at trying to get help. My Gp68 only goes to channel 10, how do I expand it to the next 10? Any help will be appreciated. If you can send me instructions or walk me through it then that would be great.

YOu need to be in programming mode. Once you set your parameters, you hold the light button for 3 seconds. The screen will then flash "Pch01"..."02", etc. You need to rotate the knob to the desired channel (1-20)and then push the light button againmomentarily, this will write the data you entered in program mode to that memory chanel.
