Internal flash is used for boot loader code and system low-level diagnostics code. Bootloader code is validated at system
startup.

One SD Memory card slot for Expansion Memory, located in the main battery well, and protected by a rubber flap. 1GB and
4GB flash memory cards are available from LXE.

Video Subsystem

The touchscreen is a 3.5" (8.9 cm) diagonal viewing area, ¼ VGA 320 by 240 pixel TFT Reflective Active Color LCD.
Backlighting is available and can be turned on and off with key sequences. The turn-off timing is configured through the Start |
Settings | Control Panel| Display icon. The display controller supports Microsoft CE 6 graphics modes.
A touchscreen allows mouse functions (tapping on the display or signature capture) using an LXE approved stylus. The
touchscreen has an actuation force with finger less than 100 grams. The color display has an LED backlight and is optimized
for indoor use.
The display appears black when the MX7 Tecton is in Suspend Mode.

Power Supply

The MX7 Tecton uses one of two batteries for operation.
Main Battery A replaceable 2200 mAh Lithium-Ion (Li-Ion) battery pack. The battery pack recharges while in the MX7
l
Tecton when the device is connected to the optional external MX7 Tecton AC/DC power source. The main battery pack
can be removed from the MX7 Tecton and inserted in the MX7 Tecton Multi- Charger which simultaneously charges up
to five battery packs in four hours. A new main battery pack can be fully charged in 6 hours when it is in an MX7 Tecton
connected to AC power and 3.5 hours when it is in the MX7 Tecton multicharger.
Low temperature Lithium-Ion (Li-Ion) batteries have a 1250 mAh capacity.
l
Super-capacitor (Super-cap). No backup "battery" is used. Super-cap internal battery maintains RAM and other vital set-
l
tings during a critical shutdown.
Note: An uninterrupted external power source (wall AC adapters) transfers power to the MX7 Tecton's internal charging
circuitry which, in turn, recharges the main battery and Super-cap battery. Frequent connection to an external power
source, if feasible, is recommended to maintain main battery charge status as the Super-cap battery cannot be recharged
by a dead or missing main battery.
