of instrument.
Using the AC Adapter (power supply)
The AC adapter powers
the AM520/AM520i
from an AC wall outlet,
and charges the
rechargeable battery
pack. The AC adapter
can run the instrument
and charge the battery
at the same time. The
battery will charge more
slowly when the
instrument is running.
Connect the AC adapter to an AC wall outlet and plug the other end
into the barrel jack on the side of the rechargeable battery.
Normal charge time is about four (4) hours with the instrument off or
when the battery is removed from the instrument.
Battery LED
When charging the battery, the
green LED in the battery pack will
repeatedly flash from dim to bright.
When the battery is fully charged,
the LED will stay on until the AC
adapter is unplugged.
If the temperature is too hot or too
cold to charge the battery, the LED
will flash 3 seconds on, then
1 second off. If the battery has an
internal fault that prevents charging,
the LED flashes rapidly.
