CK30 Handheld Computer User’s Manual 13
Using the TE 2000 Keypad
The CK30 supports TE 2000 VT100/220/320/340 and ANSI,
TE 2000 5250, and TE 2000 3270. When you order the CK30
with a TE 2000 application, you also receive the corresponding
keypad overlay. Use the TE 2000 keypad overlays to enter the
same keys that you can enter on a VT/ANSI keyboard, an IBM
5250 keyboard, or an IBM 3270 keyboard.
Like the standard CK30 keypad overlays, the TE 2000 keypad
overlays lets you enter all the characters printed on or above the
keys. The TE keypads also come with the same color-coded keys
that are on the standard overlay.
For more help using TE 2000, see the appropriate TE 2000
guide.
Understanding the Power Key
When you press the Power key to turn off the terminal, you
actually put the terminal in Suspend mode. In Suspend mode,
the terminal 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 Power key to turn the CK30 back on, your
computer resumes where it was when you turned it off. If you
are using 802.1x security, the computer may reauthenticate
before it starts your application.
If you have programmed the Resume Execution command, your
CK30 may warm boot and restart your application. For help
with the Resume Execution command, see Chapter 6 of the
CK30 Handheld Computer Configuration Manual.
If your CK30 does not resume after pressing Power, you may
need to warm boot it.
To warm boot the CK30
• Press and hold the Power key for five seconds. The CK30
will tell you it is performing a warm boot and the screen will
come back up to the splash screen or your application.
