VEMCO – VR100 Manual 28 May 2018 57
6.3.1 Charge Indicator Lights
The “Charge” indicator lights (also called LED – “Light Emitting Diode”) on the VR100’s front panel are the
“STATUS” light and the “LOW BATT” light. These lights are to the left of the ON and OFF buttons (see
photo below). The meaning of these lights is explained in the table below.
Battery is mostly charged and is in Float Charge mode
Battery is nearing discharge.
Battery is discharged and the VR100 is about to shut shown.
External power is required.
Tilt or Power System Fault has occurred – see paragraph below.
NOTE: The battery can be left in Float Charge mode for an extended period without damaging the battery.
If a Tilt or Power System Fault occurs (both lights are flashing), follow the steps below to clear the fault
and resume normal battery charging operation.
1. Ensure that the front panel of the VR100 is facing up.
2. Ensure that a proper power supply is connected to the VR100. If
the voltage is too high or too low, a Power System Fault results.
3. Place the VR100 away from direct sources of heat (including
direct sunlight) and allow it to cool.
4. Unplug the external power supply and wait for the lights to stop
flashing.
When these conditions have been met, plug the external power supply into the VR100 again. If both lights
continue to flash, unplug everything from the VR100 case (power supply, hydrophone, USB cable, and
headphones) and call VEMCO support at +1-902-450-1700 or email to support.team@vemco.com.
The VR100 can be safely used in a vertical position (front panel is perpendicular to the floor) with
an external power source connected but the battery WILL NOT CHARGE under this condition.
The “STATUS” and “LOW BATT” lights will both flash as long as the unit is vertical and an
external power source is connected. In this situation, the unit is being powered from the external
supply, and thus can be used indefinitely, regardless of the level of battery charge.
