Care and repair
Field repair

Line-cord storage
Impact
Field repairs are limited to replacing line cords
(with approved types), replacing belt clips,
and replacing batteries. Attempting any
repair beyond this at field level is liable to
damage the instrument and will invalidate the
manufacturers warranty.
Remove the three hatch cover screws.
Replace the cord by loosening the terminal
screws. Connect a new, standard cord as per
the diagram. Tighten the screws firmly but do
not use excessive force. Make sure the
battery cover locates properly before
securing it with the 3 screws.
Wrap the line cord loosely around the handle
or preferably make a few loops and pass them
through the belt clip.
is highly impact resistant. Even
if dropped from a great height onto concrete
should survive without
permanent damage. In the event that the
gasket seal should bulge out on impact it is
usually possible to gently ease it back into
position with a blunt tool. Do not attempt to
open the case to make a repair nor should any
force be used or the gasket may split. If a
simple local fix is not possible it should be
returned for repair.
As a result of impact the surface may be
scuffed or gouged. Small scuffs may be
removed with fine grit abrasive paper. Any
sharp burrs resulting from impact may be cut
off with a sharp knife. Do not cut into the body
or this will break the water sealing.
Please note that the waterproof seal integrity
can be damaged by a high impact. If in doubt,
please have your unit checked. Use of the
unit while the seals are damaged may
invalidate the warranty.
