User Manual

Chapter 1 — Using the CN4
12 CN4 Series Mobile Computer User’s Manual
Use the Windows Mobile Classic profile for systems that batch data
and upload it several times a day. This profile does not support
constant data connections over WAN, LAN, or Bluetooth. It can only
maintain data connections when the CN4 is on and all peripherals are
enabled. If the screen is off, you do not have any WAN, LAN, or
Bluetooth connections, but the CN4 will still receive incoming phone
calls. To wake up the CN4 and restore network connections, you need
to press the Power or Scan button.
Use the Windows Mobile Phone profile when you have a system that
requires network wake-up or you need the CN4 to always be
connected to the network. Although the connections are maintained
at a low power mode, this setting typically consumes the most power.
If the screen turns off, the radios continue to maintain the network
connections.
Customizing Power Timeouts
Follow the next procedure to adjust the screen and power timeout
values. You can set different values for battery and external power.
To customize power timeout values
1 Tap Start > Settings > System tab > Power Profiler.
2 In the Power Profile tab, tap Enable Advanced Settings.
3 Tap the Screen Settings tab to change screen timeout values:
• Check the Enable Screen Off check box to be able to turn off
the screen independently of the CN4.
• To change the amount of inactivity time before the screen
turns off, move the Battery Power or External Power sliders.
For battery power, choose from 1 to 6 minutes.
For external power, choose from 1, 2, 5, 10, or 15 minutes, or
disable this feature.
4 Tap the Device Settings tab to change overall CN4 power timeout
values:
Note: When you set timeout values this way, you override values used
by the Power Management Profiles.
