The LED
A single tri-coloured LED is located on the upper-left corner of the
NEO
, just above the dis-
play. Default behaviour of the LED is described in the table below. The LED can also be
controlled by application programs, using APIs found in the Psion Teklogix Mobile Devices
SDK (see Appendix A: “Resources” for details on where to obtain this SDK).

Battery & Power Management
The
NEO
is powered by a 3300 mAh lithium-ion rechargeable battery pack, and can also be
connected to an external power source using a docking station or AC wall adaptor. When the
NEO
is connected to an external power source, the battery pack also charges.
When the battery output drops below 3.1 V, the hand-held will go into suspend mode to
preserve information in volatile memory until the battery is recharged or replaced with a
charged battery. If the battery output drops below 1.6 V, the hand-held will shut down
completely, and any information in volatile memory will be lost.
Use only power sources recommended or sold by Psion Teklogix for the
NEO
.
