Charging the Backup Battery
The MC75A is equipped with a memory backup battery which automatically charges from the fully-charged main
battery. When using the MC75A for the first time, the backup battery requires approximately 36 hours to fully
charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room
temperature) when the MC75A's main battery is removed. When the MC75A reaches a very low battery state,
the combination of main battery and backup battery retains RAM data in memory for at least 48 hours.
Screen Protector
The MC75A-NI is provided with a screen protector. Motorola recommends using this protector to prevent wear
marks. A screen protector contributes to the user friendliness of the device and protects the touch screen.
Removing the Screen Protector
To remove the screen protector, lift the corner with a thin plastic card (credit card) and then pull it off the display
with care.
CAUTION
The screen protector may only be changed outside the hazardous area.
It must be ensured that only original screen protectors used in safety-oriented operation.
Use only Motorola p/n KT-67525-01R.
The use of imitation screen protectors from other manufacturers will render the type of ignition
protection ineffective and there will then be a risk of fire or explosion.
ATTENTION
Do not use any sharp objects to remove the screen protector foil. This could damage the
display.
