Motorola Talkabout T5500: No connection between radios.

Motorola Talkabout T5500: No connection between radios.
The batteries in one of the radios leaked and I cleaned up the battery compartment. Since then the affected radio sends a ring and no response is heard from the other radio. There is no response either by ringing or voice communication from either radio , no matter which one originates the call. Is there a trouble shooting procedure for coming up with a fix?
