Psion VH10 Vehicle-Mount Computer User Manual
When the VH10 is idle — not receiving any user input (a key touch, a scan, and so on) or system activity
(serial data, an activity initiated by an application, and so on) — the Vehicle-Mount uses the value assigned
in the
Suspend Timeout
field to determine when the unit will go to sleep (appear to be off).
When the time in the
Suspend Timeout
field elapses without any activity, the unit enters
suspend
state. In
suspend state, the VH10 CPU enters a sleep state, and wireless communication is shut off. The state of the
device (RAM contents) is preserved. Pressing
[ENTER]
wakes the system from suspend state.

Allow Suspend With
This menu allows you to specify whether or not your unit will enter Suspend Mode while it is operating with
an active PPP connection, network interface or active TCP/IP connection.
Power On/Off With Ignition Option
This optional feature puts the VH10 in Suspend when the vehicle ignition is turned off, and powers the VH10
on when the ignition is on. You can enable this feature and set a delay time for the VH10 to go into Suspend.
When a delay time is specified, a window appears on-screen at the time of ignition off. This window shows
the time countdown, and contains power-off-now and cancel buttons. The window is shown on top of any
running application, attached to the right side of the screen, and may be repositioned by dragging it up and
down as desired.

Built-in Devices
The Built-in Devices menu controls the power mode of internal devices. If no such device is installed, such
as the WWAN radio in the example below, this menu tab will not appear.
Note: For this feature to be available, appropriate wiring must be installed. For detailed instructions for the
electrical installation of the ignition detect system, see “Power On/Off with Ignition Option: Wiring”
on page 131.
Note: This feature does not interfere with other methods of turning the computer off and on.
