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. Check your company policy before
considering anyrepair. Although limited fieldrepair may bepossible your company mayhave a
policy of centralised repair.
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 donot use excessiveforce. Make sure thebattery cover sits downproperly 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.
Tele300B is highly impact resistant. Even if dropped from a great height onto concrete
Tele300B should survive without permanent damage. In the event that the gasket seal should
bulge outon impact it is usuallypossible to gentlyease it back intoposition with ablunt 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 returnedforrepair.
Please note that the waterproof seal integrity can be damaged by a high impact. If in doubt,
please haveyour unit checked. Use of the unit whilethe seals are damagedmay invalidate the
warranty.
