The Lithium Ion battery
The battery level indicator
The E Series players come with an improved capacity, rechargeable Lithium Ion battery.
All models come with a built-in battery level indicator. The player must be on in order to test the battery. A brief
press on the power button on the side of the player executes the test. The LED on the keypad will blink rapidly
for 2 seconds indicating the remaining capacity in the battery. The color of the LED displayed during the test
shows the remaining charge as presented below:
Green: 30% - 100%
Yellow: 10% - 29%
Red: 0% - 9%
Battery care and charging
With proper care, the player’s Lithium-Ion battery should perform well for several years. When shipped, the
battery is only partially charged. You can easily charge the player using one of the methods below:
For fastest charge, connect any standard “USB” charger (reg5VDC, minimum 300mA) to the micro-
USB port on the player for about 2 hours (or until the LED stops blinking). While charging, the LED will blink
according to the charge level described above
.
Plug the player into any standard computer USB port using a “USB to micro-USB” cable for about 3 hours or
until the LED stops blinking. Any MegaVoice SLS, regular or charge-only cable is sufficient.
For solar charging, place the player with the solar panel facing bright sunlight for at least 8 hours.
Before storing the player for prolonged periods, make sure the battery is at least partially charged. If stored for
extended periods, it is recommended to recharge the player
at most
every 6 months in order to prevent the
battery from losing its ability to charge. For optimum battery life, try to store the player at room temperature or
cooler.
Should the battery become damaged and unable to accept a charge, you can still operate the player using the
power cord (charger).
