ADDITIONAL INFORMATION

Note that this equipment should only be dismantled by properly trained personnel. Removing
the outer cover exposes potentially lethal mains voltages. There are no user serviceable parts within this
equipment.

FAULT FINDING

Should you have any problems with your BLºCKICE which cannot be easily remedied, you should contact
your supplier and return the unit if necessary. Please include details of the fault observed and remember
to return the unit in its original packing. Bibby Scientifi c Ltd. accepts no responsibility for damage to units
which are not properly packed for shipping: if in doubt, contact your supplier, giving the full serial number
of the unit.

FUSES

If the display on the front panel is not lit, one of the two fuses may have blown. Check that there is no
external cause, such as a faulty plug or lead. Check both fuses and replace the faulty fuse with a new one
of the correct value (fuse values are given on the label next to the power inlet). Note that fuses should
only be replaced by a qualifi ed electrician.
The holder for the two fuses is built into the mains input socket. First remove the power cable and then
gently prise the fuse drawer open with a fl at-bladed screwdriver or similar tool. Each fuse can be removed
by using the screwdriver as a lever.
Exchange the faulty fuse in the fuse holder for a working fuse of the correct value. Finally, replace the fuse
drawer in the fuse compartment and push the drawer shut. Fuses which blow repeatedly indicate a serious
fault and you should return the unit to your supplier for repair.

INSULATION TESTING

This equipment is fi tted with RFI suppression circuitry. Any check of the electrical insulation by means of
high voltage dielectric testing (for example as in BS EN 61010-1) must be carried out using only a DC
voltage.
This unit contains semiconductor components which may be damaged by electric fi eld effects.
