June 2003 IPN: M5000-00-105 Tait Orca vehicle kit F - 13
Servicing the vehicle kit
The vehicle kit contains four PCBs, and the
following servicing instructions outline the
disassembly of the vehicle kit to allow replace-
ment of these PCBs.
Warning: Screw head types
There are four different types of Torx screws
used in the vehicle kit: KC22x6, KC25x6,
KC30x8 and KC30x10. All these screws require
a Torx head screwdriver. When tightening any
screws, be careful not to strip the threads in the
plastic mouldings by exerting too much force.
The following table explains the torque
settings required for the different Torx screw
types.

Removing the vehicle kit back cover
The back cover is held to the front moulding by
two plastic clips at the base of the unit. Insert
the tip of a round screwdriver into the two
holes at the bottom of the rear panel. Lever the
tip upwards towards the top of the unit.
Hold the unit in such a way that your forefin-
ger and thumb exert a slight pressure to
separate the rear panel away from the front
moulding, while you lever the clips with the
screwdriver.
Replacing the accessory probe PCB
Remove the back cover and unplug the acces-
sory loom at the top of the options PCB.
Unscrew the two KC30x10 screws holding the
trigger assembly together. The trigger assem-
bly can now be lifted out.
Note that the trigger assembly must be pressed
downwards
downwardsdownwards
downwards while undoing these screws, as
there are springs underneath.
Unplug the loom from the accessory probe
PCB. Carefully use narrow nose pliers to
unplug the MCX connector from the accessory
probe PCB. Now remove the two KC22x6
screws on the front of the vehicle kit holding
the accessory probe PCB into the front mould-
ing. The accessory probe PCB can now be tilted
upwards and removed from the moulding.
Fit the seal onto the new accessory probe PCB
and reassemble the vehicle kit. Read the
assembly instructions for more information.
Replacing the charger probe PCB
Remove the back cover and unplug the acces-
sory loom at the top of the options PCB. Lift
the options/charger PCB assembly out of the
front moulding, until the charger loom is
accessible.
Unplug the charger loom and remove both
PCBs from the front moulding. Note that these
PCBs are still attached via the RF cable.
Unscrew the two KC30x8 screws holding the
charger probe moulding into the front mould-
ing, and slide out the probe moulding.
Unscrew the three KC25x6 screws holding the
probe PCB to the probe moulding. Fit the seal
onto the new charger probe PCB and reassem-
ble the vehicle kit.
Removing the options or charger PCBs
Remove the two DB25 fasteners holding the
back panel to the accessory/options connec-
tor. Remove the two KC30x10 screws holding
the back plate to the audio PA. Unclip the
backplate from the options PCB. The PCBs can
now be unplugged and replaced.
When putting the options/charger assembly
back into the front moulding, make sure that
the charger PCB is running in its tracks. Be
careful that you do not bump the LED at the
bottom of the charger PCB; the PCB does not
require any force to insert.
