Chapter 7 Maintenance

This chapter explains the maintenance methods to use the device in optimum
conditions. Consult your local service center if you have any further questions.

7.1 Daily

maintenance

-

Do not use a volatile solvent. If the device is dirty, slightly wet a soft cloth with a

neutral cleaning agent, wring out the cloth thoroughly, and gently wipe the device.

-

Wiping with liquid dripping from the cloth may result in a malfunction due to the

liquid seeping in the case, between gaps of the side keys or touchscreen, or into
the sheet keys.

-

Prevent the device from getting dirty. Contact will be defective and the device may

not operate properly if the device power supply terminals or battery pack terminals
are dirty. Wipe gently using cotton buds if the terminals are dirty.

-

Make sure to prevent dirt. Leaving dirt on the battery pack rails until the dirt

hardens may make it impossible to remove the battery pack.

Caution

Never touch the terminals except for cleaning. This may result in defective
contacts.

Never raise or push down on the terminals.
