OMNII™ STANDARD BACK COVER KIT INSTALLATION
INSTRUCTION SHEET
1. Introduction
This document describes the procedure for installing the standard back cover kits for the Omnii hand-held
computer. Depending on the specific kit model, the standard back cover will include a scanner or imager module
which must be connected to the main logic board of the unit.
These instructions apply to the following upgrade kits for the Omnii hand-held computer: ST9701, ST9702, ST9703,
ST9706, ST9707, ST9708, ST9709 and ST9714.
Warning: The installation of a back cover must be performed using the appropriate anti-static devices. If
unavailable, discharge static from your body by touching a grounded metallic object before
opening any covers on the unit.
Warning: Psion scanners contain Class 2M (or lesser) laser products. Direct exposure to laser radiation can
cause serious eye damage. DO NOT stare into the beam, or view directly with optical instruments
(binoculars, telescopes or magnifiers).
Warning: Always disconnect Omnii from all battery and A/C power before servicing components.
The kit includes the following items:
• standard back cover with scanner or imager module mounted, as specified by kit
• T10 Torx screws (x8)
• T6 Torx screws (x2)
• pistol grip switch cover
The following tools are required for this procedure:
• T10 Torx screwdriver
• T6 Torx screwdriver
2. Module Installation
Important: Back up any data in RAM first, since it will be lost when power is removed from the unit for
longer than five minutes.
1. Remove the battery.
2. Follow these steps to remove the existing back cover, if one is present.
a. Use a T6 Torx screwdriver to remove the two topmost screws on the front of the unit, above
the display.
b. Use a T10 Torx screwdriver to remove the eight screws holding the back cover to the main unit.

c. Gently pull the back cover away from the main housing, being careful to not put stress on any
cables connecting the two parts.
d. Disconnect any cables between the existing back cover and the main unit.
3. Insert the end of the scanner or imager flex cable from the back cover in socket J13 on the main logic
board as shown in Figure 2. The exposed contacts on the cable should be facing towards the top of the
unit. If no scanner has previously been installed, there may be a small piece of “dummy” stiffener
present in the socket, which must be removed before inserting the cable.

4. Insert the pistol grip trigger wire harness in the white socket on the left side of the main logic board.
5. Fit the back cover in place against the main housing, ensuring that no cables are caught in the seal.
6. Install the eight T10 Torx screws in the back cover and torque to 5 in-lb (0.56 N-m). Install the screws in the
sequence shown in Figure 1 to ensure a consistent seal all around the opening.
7. Install the two T6 Torx screws in the front of the unit above the display. Torque the screws to 2.5 in-lb
(0.28 N-m).
8. If no pistol grip will be installed, the hole in the back cover for the pistol grip switch must be covered using the
supplied cover.
a. Clean the indicated area using isopropyl alcohol.
b. Peel the covering from the adhesive gasket on the pistol switch cover.
c. Press the pistol switch cover in place, and hold it firmly in place for 30 seconds.
9. Replace the battery.
10. Newer standard back cover kits like the ST9714 may require a software update to the hand-held. This software
update may also require the installation of an add-on CAB package. Contact your Psion representative for
additional instructions.
