In play-back, buzzing/static after 10+ seconds of recorded message

Can you tell me about the phone you use (In detail)?
I will help you with a sol'n Insha Allah

The buzzing noise is static from the engine, if it does not make the noise when the key is on but engine not running. If so make sure you have a good ground. Most of the time I have found that to be the problem.

1. Set the DM-10 to Voice mode using the blue switch on the back voice recorder.
