Vehicle Install
If the receiver is installed in a vehicle, it is recommended that a dedicated battery be provided for the receiver
that is isolated from the engine starter battery. When a vehicle engine is started, the voltage on the starter
battery can dip below the PwrPak7 minimum voltage or cut-out to ancillary equipment causing the receiver
and/or IMU to lose lock and calibration settings.
