Hi. Had the same problem earlier. (I assume you use an original or compatible head set cable.) It turned out to be caused by corrosion/dirt on the contacts on the bottom on the phone. You should inspect it and you can use a small sharp object and gently scrape/rub the contact points until any dirt or miscoloration is removed. In the end these contacts will need to be replaced as they suffer from wear and tear as well as corrosion. New contacts are available as spare parts from many internet sources. If you need help to open the phone and change contacts, please add a separate request.

We use these radios in a race car.They work fine until you hook up the headset for the spotter to use and it drains down the battery real fast.Brand new batteries.


It is possible the headset you are using is not the one engineered for the radio, and draining the battery. Or this radio is being transmitted on heavily and running down the battery. You might try changing headsets and see if the problem clears up. Not all headsets compatible with other Motorola Radios will work with the BPR40.

Best regards.

Using headset jack - unit always transmits


Try plugging in headset BEFORE turning on radio. You should see the word VOX (not iVOX) on your display. At least this is what works for me.

Compatability bluetooth headset K 750i/K800


Hi, The way that I paired my device is by pressing and holding the two volume buttons simultaneously for about 5 seconds, until the red and green lights began to appear. Then, i just 'refreshed' my bluetooth search for devices, and it discovered it, and was able to pair it up. Hopefully, this is useful
