Care of the touchscreen
Use only the included stylus or other devices specifically designed
for use with touchscreens. The use of ballpoint pens, sticks, nails or
other sharp objects to operate the touchscreen will scratch and/or
damage the unit. Abrasives may scratch touchscreens. Keep the
touchscreen clean by gently wiping the display, using a soft cloth
dampened either with clean water or glass cleaner. Do not apply
any cleaner directly to the display. Do not use any abrasive
cleaners.
Use the screen protectors included with the unit to keep the
touchscreen clean and protected. To apply a screen protector, first
clean the display thoroughly. Peel the backing from the screen
protector. Align the edge, and then drop the remainder onto the
display. Use a credit card, if necessary, to squeegee the air from
underneath the screen protector.
Care of the PowerBoot Module
The PowerBoot Module contains rechargeable Lithium Ion (Li-Ion)
cells that power the unit.
Charging guidelines:
It is not possible to overcharge the batteries. They are self-
regulated. You may leave them on charge indefinitely with no
adverse consequences to their service life.
Use only the charger supplied with your unit. Use of other
chargers may void your warranty.
The acceptable temperature range for charging the battery is
between +5°C and +35°C (+41°F and +95°F). This is based on
the internal battery temperature that may be different than the
ambient temperature. If the battery detects a temperature too
high or too low for charging, the LED will flash a warning
sequence. The PowerBoot Module will defer charging until it
detects appropriate temperatures.
