Sometimes after a power outage the headset will lose sync with the headset's base unit.  If you hear a constant ringtone or beeping in the headset you will need to perform a full reset.  This reset is only for the Jabra PRO series (920, 925, 930, 935).  It will allow the headset to "sync" again with the base unit so the constant beeping will go away.  The instructions below will generally fix this issue.  If the steps below do not fix your issue our Virginia-based Headset Experts can help you troubleshoot for a $35 support fee.

Jabra Pro 900 series Reset:

1. Place headset on the charging base
2. Remove power from charging base
3. Take headset off charging base
4. Hold multifunction button (the one in the silver ring) for 4 seconds
5. The white light will flash 3 times and then flicker. When it begins flickering, let go.
6. There should now be no lights on the headset.
7. Place the headset back on the base and plug the power back in
8. Charge until the battery light is steady green and test the unit
