POWER SUPPLY UNIT MODULE WITH LITHIUM-POLYMER
Built-in Ba ery, Charging Indicators and Ba ery Meter
The instrument is powered by a Li-Polymer ba ery of high efficiency and capacity, allowing
the user to play the instrument for many hours without any problems, and without worrying
about deple ng the ba ery.
The ba ery charge level can be checked with the
use of a meter on the backplate. The meter includes
four LEDs and a CHECK bu on that allows for
momentarily checking the ba ery charge levels. A er
pressing that bu on, depending on the charge level,
one, two, three, or all four LEDs would light up. When
all four LEDs are on, including the top, the green one,
this means that the ba ery is charged to 75-100%.
When a er the bu on is pressed, three LEDs are on
(low red, and two mid yellow ones), and the ba ery
charge level is between 50 and 75%. When two lower LEDs are on, that designates a charge
level between 25 and 50%. The below 25% charge level is indicated when solely the lower, red
LED is on. If the ba ery charge is very low, no LED would light up. When the meter indicates low
ba ery charge levels (red LED is on), or when no LEDs are ac ve when pressing the bu on,
please charge the onboard ba ery as soon as possible. That would allow the user to retain the
nominal ba ery capacity.
