upper camlock. This part may wear out with normal use.
 Open middle and upper camlocks and fully extend and close the shafts several
times making sure there is no snagging or obstruction. In particular check that
the shafts fully close with no obstruction. It is possible for dirt to build up inside
the shafts and compact around the coil connector. If there is any doubt the
electronics pack should be removed so that the inside of the shafts can be
checked for obstructions.
 Inspect the battery lid. Remove, clean, lubricate then replace the battery lid O
ring.
 Check the battery lid tether and replace if it if damaged or misshapen. If the
battery tether is not straight and in good condition it may fold up between the
battery and the battery terminal causing the detector to turn off and on.
 Check the inside of the battery pack and clean if necessary, don't use water or
chemicals just a dry cloth or brush. Check the battery contacts are clean and
are not corroded. Do not bend, stretch or modify the battery spring terminal.
 Check that the battery pack can be removed from and attached to the detector.
 Remove the endcap and check all screws in the electronics pack are in place
and tight.
 Check that the wiring loom under the endcap is undamaged and not loose
where it enters the grommet into the electronics pack.
 Check the armrest for any cracks or damage. Open the armrest camlock and
slide the armrest up and down then close the camlock making sure the armrest
is held firm.
 Check the arm strap is correctly attached to the armrest, if the arm strap is
damaged and no longer effective replace the strap.
 Check the handle for damage. Check the on/off switch moves back and forth
correctly if there is a build-up of dirt the handle will need to be opened to clean
around the on/off slider.
 Give the detector a good clean.
 Check all accessories are present and in good working order.
 Check the detector hard case for damage.
 Conduct the
Functional Testing.
 Complete documentation, record the serial number of the detector serviced. A
service log should be kept so that there is a record of when each detector is
serviced or checked.
 If a detector is missing its serial number label the serial number can be replaced
on the upper shaft using a paint pen or similar. There is a secondary serial
number under the battery pack. If the original serial number cannot be found
then a new serial number must be created for future use.
