Chapter 2: Basic Skills
Maximizing the Battery Operating Time
•
Whenever possible, use the device with the AC Adapter – especially when it is connected to
your computer.
•
Select the short powered-off time in the setting menu. This will shorten the time the unit will
remain on if not used. See "Customizing Your Device" later in this chapter for more information.
•
Turn off the front light.
•
Set the screen brightness to power savings mode (front light off) or shorten the front light
turn-off time. See "Customizing Your Device" later in this chapter for more information.
•
For optimal performance use in an environment between 59 F - 77 F (15 C and 25 C).
Anything outside this temperature range may decrease the operating time.
Battery Life
The built-in battery has a limited life that will gradually decrease after repeated charging. Replace
the battery when you notice a dramatic decrease in battery performance.
Battery Charge Level and Stored Data Protection
If the battery charge level becomes extremely low or completely discharged, stored memory data
will be deleted. As soon as the low battery status icon or the alarm message appears, immediately
connect the AC Adapter to the device so it can charge.
• The battery gradually discharges even when not in use. If not used for a long time, it may
completely discharge.
• It is strongly recommended that you save the device's memory data to your computer or a
storage card. The manufacturer is not responsible for data changed or lost due to battery
discharge. For back up, see "Backing Up" in Chapter 9.
