Battery replacement
• Only use approved battery types. See table in section 7: Technical data.
• Always replace all of the batteries together.
• Make sure that the polarity of the inserted batteries is correct.
• Please ensure that all used batteries are properly disposed of in an
environmentally friendly manner.
• After changing the batteries or the sealing rings always check to make
sure that the sealing rings and threads are clean and in a good condition.
8.4. Cleaining the rotary switch
A non-contacting rotary switch is used to switch on the Lite-Ex PL 30e (see
description above). Dirt or moisture does not effect the function. The rotary
switch is easy to clean if excessive amounts of dirt and grime have made it
difficult to turn. First take off the torch body and remove the batteries (see
section 8.3 Battery replacement). Remove the rotary switch by sliding it off
the back of the torch, and then clean the switch. When putting the rotary
switch back on, make sure that the arrow marks on the ring line up with the
alignment screw on the bottom part of the torch head (see picture 1). Then
re-insert the batteries, and screw the body of the torch back on.
8.5. Lamp replacement
The Lite-Ex PL 30e is equipped with an extremely long-lasting LED lamp.
Replacing the LED is normally not required. If, however, the torch is
defective or the brightness of the torch has diminished, it should be sent to
ecom instruments for inspection or repair. Under no circumstances should
you attempt to open the torch head. Manipulating the torch head or LED on
your own poses a risk to the safety of the torch and is not permitted.
8.6. Replacing the spare disc
The torch head is protected by the housing head that surrounds it as well
as an additional disc, which is positioned over the opening where the beam
is emitted. The disc is made of high-quality material. Should, however, the
disc break, it is possible to replace it. To replace the disc, hold on to the
body of the Lite-Ex PL 30e and the twist ring, and carefully unscrew the
housing head by turning it anticlockwise. Clean the housing head thoroughly
