3. Turn power switch ON to the “1” position
(plug in power cord for AC operation).
Observe LED indicators to confirm battery level and power.
Battery Power
: The green light indicates the battery is at or
near full charge and ready to use. The yellow light means 30-60%
usage remains, and red means less than 30% remains and that
the battery should be charged before use (see below).
AC Power
: When plugged into an AC power outlet, the green
LED will stay on constantly as the system is being powered from the AC line
(not the battery). Occasionally, when playing loudly, the LED’s may flicker
between green and yellow - this is normal.
4. Adjust the volume level.
Increase the volume of the input being used to desired level (be sure the
microphone or input source is turned on!)
Charging the battery.
While it is not harmful to store your VM-2 with a partially discharged battery,
charging after each use will ensure maximum operating
time for your next event. We also recommend charging if
the battery has been completely run down or before plac-
ing into storage. Optimum charging is achieved when
the battery is charged between 0 and 40 degrees centigrade (32-104 Deg F).
If the outdoor environment is unusually warm or cold, bring the unit indoors
before charging.
Charging the battery.
Turn the system “off” and plug the cord into a standard AC outlet to charge
the battery. The system automatically begins charging, indicated by the yel-
low charging LED. When the green full LED illuminates, the battery is fully
charged and the unit is ready for use or storage.
The typical time to recharge an empty battery is 7 hours.
