Instructions for use Hartenberger High-Tech-UW-Lamp nano compact
The bold printed figures represent the burn times with the standard bulbs as
supplied with the lamp from the manufacturer.
Halogen bulbs available in retail outlets often need up to 10% more power as
stated. The stated burn times will therefore be shortened.
Low ambient temperature have little effect on lithium manganese cells. These
special cells have approx 95% capacity in water temperatures between
0° and 5° Celsius (32° - 41° Fahrenheit).
A 3% - 10% reduction in performance over 12 Months can be regarded as normal
life reduction.

FRONT GLASS PLATE
The nano compact lamps have a tempered glass plate as standard. This glass
plate has a temperature shock resistance of 150°C ( 300°F). It is therefore
possible to use the lamps above and under water. A rapid cooling of a heated
front glass is no problem (for example if used temporarily above water in order
to orientate oneself on the surface of the water).
FRONT HOUSING COVER
FRONT GLASS COVER
The O-ring (40 x 3,0 60° hardness) seals the front glass plate in the cover and
is specially pressed into the cover by the manufacturer. This O-ring must be
replaced every 5 years, or earlier if it is shows sign of deterioration (such as
cracking). This job may only be carried out by an authorised workshop
