Important
• Take care so either of the units does not move while infrared data communications
are in progress.
• Infrared data communications may be impossible under strong sunlight or inverter
type fluorescent lighting.
• Infrared data communication problems can be caused by the distance between the
two ports, the angle between the two ports, outdoor sunlight, and low batteries.
• Dirt and dust on the infrared port surface can cause communications errors and other
problems. Use a soft, dry cloth to wipe the port clean of dirt and dust.
Resetting the Unit
“Reset” is similar to a computer reboot. Performing a reset deletes any data that is in
the process of being input or edited, without yet being saved. Data stored in memory
and all settings, however, are retained.
Perform the reset operation whenever the unit fails to operate correctly due to
operational error or some other abnormality. Either of the following symptoms
indicates that reset is required.
• If the unit does not respond when you tap the screen or press a button
• If the icon that indicates a procedure is in progress remains on the display for a long
time
Important
We strongly recommend that you back up the data in CASSIOPEIA memory, if
possible, before performing a reset. Normally the reboot-type reset does not delete data
in CASSIOPEIA memory. If corrupted data is discovered, however, all data stored in
memory will be deleted. Not matter what type of computing device you are using, it is
always a good idea to back up memory contents periodically to protect against
unexpected loss of data.
Performing a Reset
1. Use the stylus to press the RESET button.
