The manual was complete and extremely helpful in both diagnosing the problem I was having as well as fixing it. Excellent quality. I will getting additional manuals in the future.
Exactly the JVC service manual and schematics that I was looking for - delivered just hours after order. Will do business again!

5.4. Dial Lock
You can prevent others from making a call to any number except the one pre-programmed in the memory of the EMERGENCY button. Once you locked the dialing buttons, even emergency numbers cannot be dialed. Only incoming calls are accepted until the dial lock is canceled. Before using this feature, we recommend storing an emergency number in the memory of the EMERGENCY button. Even if the dialing buttons are locked, the number stored in the button can be dialed.
