Chapter 1 — Using the CK30 Handheld Computer
14 CK30 Handheld Computer User’s Manual
Using the Power (I) Key
When you press the I key to turn off the CK30, you actually
put the CK30 in Suspend mode. In Suspend mode, the CK30
continues to supply power to all memory, but turns off power to
most hardware. This power-saving feature is designed to prolong
battery life.
When you press the I key to turn the CK30 back on, your
computer resumes where it was when you turned it off.
If you are using WPA or 802.1x security, the computer may
need to reauthenticate before it starts your application.
If the Battery light flashes and your CK30 does not resume after
pressing I, your battery may be too low to supply power.
Replace the battery. If replacing the battery does not solve the
problem, see “Booting the CK30” on page 102.
Using the Screen
The CK30 can have either a color or monochrome display
depending on the model. Both screens are 160 x 160 pixels. The
work area is 160 x 140 pixels and the status bar is 160 x 20
pixels. In addition, the screens support Unicode characters, user-
programmable fonts, and bitmap graphics.
