If the MX5 has a dead main battery and is as cold as the extended operating
temperature’s lowest value, the unit must be warmed to above –20°C (-4°F)
before installing a new main battery pack and pressing the On button.

Using the Power Key

Note: Refer to the section titled "Power Modes" in the “MX5 Reference Guide”
for information relating to the power states of the MX5.
The Power key is located next to the <Z> key on the keypad. When a battery is
inserted in the MX5 for the first time press the Power key.
Tapping the Power key places the MX5 immediately in Suspend mode. Tapping
the Power key again, or connecting to AC power, immediately returns the MX5
from Suspend.
Reboot Sequence
When the Pocket PC desktop is displayed or an application begins, the power up
(or reboot) sequence is complete. If you have previously saved your settings,
they will be restored on reboot. Application changes are saved when OK is
clicked on an application applet.
Warm Reset
Hold down the Power key and the Orange key for 4+ seconds until the display
blanks, then release the keys. A warm reset does not affect the operating system
and no data loss occurs.
Cold Reset
Hold down the Power key, the Blue key and the Orange keys for 4+ seconds.
The following steps will need to be performed when the MX5 powers on again:
1. Calibrate the touch screen.
2. Set the geographical Location.
3. Set the date and time.
Important:-- Because of the extreme nature of the Cold Reset, LXE
recommends that the Cold Reset be used only as an emergency
procedure and the Warm Reset be used whenever necessary.
LXE recommends the RegSave file be run whenever configuration
changes are made.
