7.2 Battery Replacement
When the brightness is no longer
satisfactory and the batteries are to be
replaced, it is strongly recommended
that all 3 batteries should be replaced as a
set. When replacing the batteries
ensure that only type-approved batteries
are used (see table of type-approved
batteries in section 6. Technical details).
PLEASE NOTE:
The batteries must only be changed outside
of the Ex-hazardous area.
The use of any other type of batteries is
strictly forbidden in that it will invalidate the
Ex-data certification.
To change the batteries, first remove the
safety screw – using a suitable
screwdriver. The base cap can now be
removed - by unscrewing in an
anticlockwise direction.
The batteries can now be removed.
Before fitting new batteries ensure that the
contacts of the new batteries and those in
the torch are clean. After the batteries have
been inserted, refit the base cap and secu-
re with the safety screw.
Please check that the sealing ring has not
become damaged when opening and clo-
sing the torch
(ref. special conditions see paragraph 4.3).
