IBM MX5 - Manual (Page 13)

The trigger handle is a mechanical device. Battery or external A/C power is not
required for operation of the trigger handle. The trigger handle does not need to
be removed when replacing the Main Battery pack.
Either the trigger handle is attached to the MX5 or the handstrap is attached, not
both.
Handle Installation
1. Place the MX5, with the screen facing down, on a flat stable surface.
2. Slip the L-shaped plastic hooks, at the top of the handle, into the slots
on each side of the back of the MX5 and slide the handle downward until
the screw holes are visible.
3. Attach the pistol grip handle to the MX5 with the set of three screws and
washers provided.
4. Test the handle's connection making sure the MX5 is securely connected
to the handle.
Periodically check the pistol grip handle for wear and the connection for
tightness. If the handle gets worn or damaged, it must be replaced. If the pistol
grip connection loosens, it must be tightened before the MX5 is placed in service.
Install Handstrap
Note: Either the trigger handle is attached to the MX5 or the handstrap is
attached, not both. LXE recommends that, in the absence of a trigger
handle, the handstrap be used at all times.
An elastic hand strap is available for the MX5. Once installed, the hand strap
provides a means for the user to secure the computer to their hand. It is
adjustable to fit practically any size hand and is easily moved to allow installation
or removal of the MX5 battery pack.
Installation
1. If a handle is installed, remove it at this time. See section “Install Pistol
Grip Handle.”
2. Slip the strap through the upper bracket prior to securing the upper
bracket to the unit.
3. When slipping the strap through the bracket make sure the closed loop
fastener surface is up.
4. After slipping the strap through the bracket, fold the strap over so that
the two closed loop fastener surfaces mate evenly.
5. Prior to securing the upper bracket to the unit, slide the bottom
assembly into the slots at the bottom of the MX5. Insure that both ends
of the bottom assembly are securely installed.
