attached to the unit and the battery replacement switch is set to the "NORMAL
OPERATION".

• It is necessary to execute Full reset. This will clear out the passcode but you will lose
all data created and saved, and add-on programs installed to the unit. (See the
Start-up Guide: "What to do if a problem occurs" on Appendix pages.)
• The AC adapter and unit become hot while using the AC adapter or

during charging.

adapter is used or during charging.

• A rainbow pattern is appearing on the screen.

• A rainbow pattern may appear on the screen when the unit is used outdoors on a
sunny day, etc., but this happens because of the interference occurred by the light
rays and is not a malfunction.

• Application start up is slow.

• The start up time can be shortened in some applications. Tap and hold an application
icon on the Home screen for a few seconds, then check the "Fast load" checkbox on
the screen displayed. This will consume more memory.
