Well Im on vacation and I got my brand new P2V+ a couple hours ago. It came with firmware version 3.0 and the first thing I did was downgrade to 1.08. I charged my battery and then did the advanced IMU calibration and all was good. The problem im having is when I first turn it on all the lights come on and then the front lights go out and never come back on. I tried to calibrate the compass by flipping my S1 switch but cant get it into calibration mode. Any ideas on whats going on? Im in Northern Michigan and im using dial up internet so its taking forever to search the web. Thanks.
