BATTERY INFORMATION AND CARE
Your DynaVox device has a 7.4V Lithium Ion (Li-Ion) battery pack.
When fully charged, this battery pack will continuously power a
MightyMo for approximately 10-12 hours, or a MiniMo for
approximately 6-8 hours. A DC power adapter/charger was provided
with your device and should be used to recharge the battery when the
power level becomes low.
There are various ways to extend the daily runtime of your battery.
• You can use the DC power adapter/charger to connect the device
to an electrical outlet while using the device.
• You can reduce the amount of light behind the device’s screen.
Setting the device to maintain lower screen brightness will use less
power.
• You can use the backlight timeout feature to dim the touch screen
slightly if the device has been inactive for a specific amount of
time. This low-power state will extend the runtime of your device
battery.
If your battery pack is unable to maintain a usable power level after
being charged, it will need to be replaced. It is not necessary to send
your entire device in to the repair department to replace the battery
pack. The battery pack can easily be replaced at home. Replacement
batteries are available from DynaVox Technologies.
The remainder of this section includes steps for conserving battery
power, recharging a battery and installing a new battery.
