Charging the Battery
Batteries shipped from the factory are charged to approximately 40% of capacity. Lithium-
ion battery packs must be fully charged before use. These batteries can be charged with a
variety of chargers and docking stations. For detailed information on these accessories,
please see Chapter 6: “Peripheral Devices & Accessories”.
Normally it takes 3 to 4 hours to charge a battery. The Omnii intelligent charging system
protects the battery from over-charging by terminating the charge process when the battery
is at maximum capacity.

The Keyboard
Omnii offers a wide variety of Alpha and Numeric keyboard layouts. See “Keyboard and
Keypad Kits” on page 171 for a list of available configurations. Most of the keys on these
keyboards operate much like a desktop computer. Where a key or key function is not consis-
tent with the PC keyboard, those differences are described in the following sections.
Omnii is equipped with an [Enter/Power] key that allows you to switch the unit on and to
shut down the unit to
Suspend
or
Standby
mode. For details refer to “Switching Omnii On
and Off” on page 15.
There are a number of modifier keys that provide access to additional keys and system func-
tions, as described in “Modifier Keys” on page 39.
Important: If your Omnii fails to power up, consider the following troubleshooting
options:
The battery may be overheated (>60C°), a non-Psion Teklogix battery may
be installed, or the battery may have fallen below the configured Suspend
Threshold. See “Suspend Threshold and Estimated Battery Backup” on
page 110 for details.
To switch on the hand-held, you will need to replace the overheated battery.
However, if you supply AC power to Omnii with a battery that falls below
the configured Suspend Threshold, the unit will switch on.
