Chapter 1 — Using the CK31 Handheld Computer
12 CK31 Handheld Computer User’s Manual
To disable Caps Lock
• Press the orange B key and then press either Shift or A
(depending on your keypad). The Caps Lock icon disappears
from the status bar.
Using the Power (I) Key
When you press the I key to turn off the CK31, you actually
put the computer in Suspend mode. In Suspend mode, the
CK31 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 CK31 back on, your
computer resumes at the screen that was displayed when you
turned it off. If you are using WPA or 802.1x security, the
computer may need to reauthenticate before it resumes your
application.
If the Battery light flashes and your CK31 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 CK31” on page 125.
Disabling or Modifying Keypad Functions
If you want to restrict the ability to perform adjustments made
from the keypad, such as changing the beeper volume, you can
disable the functionality of several keys on the keypad.
You can disable these keypad functions:
• Beeper volume
• Task Manager (opened by pressing Alt and then Tab)
Note: When you disable Alt Tab, you also disable Alt Esc.
You can modify this keypad function:
• The behavior of the I key. You can configure the boot
functionality to either warm or cold boot when you press and
hold the I key for five seconds.
