REMOVING / REPLACING THE HALOGEN BULB
The halogen bulb is accessible after opening the front and rear housing covers.
Access to the halogen bulb stowage is easier when the rear housing cover is
opened (see page 8).
RISK OF INJURY THROUGH BURNING!
The halogen bulb remains very hot for an extended period of time after use!
Do not touch the halogen bulb with your bare fingers. Residue on your fingers can
remain on the glass during normal use may form carbon. This will reduce the
efficiency of the bulb. Use a clean cloth or tissue to remove the bulb from the
socket. When refitting or replacing the bulb, ensure that it is located all the way
into the socket. To produce an even illumination, it is imperative to ensure that the
bulb sits upright in the socket. Assemble the lamp and check for correct fit and
operation.
To prevent plastic components and the cells of the lamp from overheating
and becoming damaged by heat, the halogen bulb should only be switched
on when the housing is completely assembled and all covers are screwed
tight.
SPARE HALOGEN BULB
There are 2 halogen bulb stowage compartments adjacent to the bulb socket.
Bulbs are safely stowed in these compartments and the plastic cover prevents
them from inadvertently falling out. This cover must be turned open to access the
bulb stowage (see Fig.4, II).
LED MODULE
The optional LED-Module replaces the standard halogen bulb and front
cover/reflector. The module is connected electrically by plugging it into the
halogen bulb socket. (see fig. 4, III). The plug arrangement prevents incorrect
fitting/connection. If the lamp does not function properly, remove the plug module,
rotate it 180° and refit it into the halogen bulb s ocket. Take care not to short
circuit the contacts.
REAR HOUSING COVER (THREADED CAP)
THE REAR HOUSING COVER SEALS
The double O-ring seals on the charging socket, the over pressure indicator and
the lamp conductor insert can only be replaced by the manufacturer.
Based on the experience gained to date, this service work should be carried out
every 4-5 years (with intensive use in diving schools, every 3 years).
Our experience with other models indicates that these seals are in good condition
after this period.
Please get the latest information from our web site
(http://www.hartenberger.de/pdf/e_bet_nano.pdf) on service intervals and
recommended life spans the can change with time/experience.
The plastic components on the rear housing cover should not be exposed
to any solvent based agents, such exposure may result in cracks in the
components and subsequent leakage/flooding.
