I already wrote about solving this problem.
The gold-plated surface of channel switch’s code disc is quickly wears in radio DP3600 / DP3601.
Radio is spontaneously switching to lower-numbered channels. Only on channel "1" this defect is not observed.
Channel switches replacement is very consuming operation.
I’ve found a nice solution to this problem:
- Each channel is placed in a separate zone;
- Assign zone name same as the corresponding channel name;
- Appoint one of the buttons for selecting zones;
- Set channel switch to position “1” and do not use it anymore;
- Now paging zones buttons "<-", "->" and pressing "OK" button is a choice of channels;
Note: Zones in the radio always automatically arranged in alphabetical order, regardless of their location in the CPS.
Excuse me for my English.
