Instructions for use Hartenberger High-Tech-UW-Lamp nano compact
glass. If reduced brightness is required on an extended basis, then a lower power
rating halogen bulb is recommended.
LOW LEVEL CAPACITY WARNING
When the lamp blinks 3 times, the user is warned of the immanent end of the
burn time of the lamp. When the lamp is being used with the standard 20 watt
halogen bulb at 100% power, this will be approximately 10 minutes after the
3 blinks. If applicable, you should abort the dive as fast as possible and turn the
lamp off (reduce the power setting).
Further use of the lamp will increase the wear and tear on the cells and
reduce their life expectancy.
DISCHARGE WARNING
Warning !
At the latest, the lamp should be turned off and no longer operated when it
starts to blink continuously. Further use of the lamp will damage the cells
and should only be practised in an emergency.
The duration of blinking with the standard halogen bulb set at 100% power is
approx. 1-2 minutes. If the lamp is switched over to 25% power, then approx.
3 minutes of continuous light is available. After this, the light will go into a blinking
mode once again.
DISCHARGE PROTECTION
Warning !
The discharge protection will turn shut down the lamp after the continuous
blinking. In the case of an emergency where light is necessary, the lamp (if
possible after a short pause) can be reactivated and will automatically turn
on at 25% power setting. The cells are almost certainly damaged should
this mode of operation be selected.
If the blinking stops or if the light becomes visibly weaker and has a yellow
tint, then there is probably an error in the electronics. Stop operating the
lamp as soon as possible and return it to the manufacturer for
evaluation/repair.
Due to the previously mentioned risks of damage to the cell pack as a result
of severe discharge, the lamp should never be operated without constant
supervision and control.
TEMPERATURE MONITORING AND WARNING
During operation, the electronics constantly monitor the temperature of the cells.
If the temperature exceeds 60°C (140°F), a warning will be generated and the
LED display will begin to blink quickly (4 x per second) and the power of the lamp
will automatically reduce to 25%. If this occurs, shut off the lamp and allow it to
cool down (unless in an emergency situation where the lamp is necessary).
Return the lamp to the manufacturer for evaluation.
If this function does not activate, a secondary monitoring will shut down the lamp
(halogen bulb and LED display) at 75°C (167°F). In this case, the lamp cannot be
operated any more. Return the lamp to the manufacturer or replace the cell pack
with a new unit.
WATER INGRESS WARNING
If a substantial amount of water enters the lamp and reaches the power pack
circuit board, a warning will be generated; the LED display will begin to blink
quickly (4 x per second) and the power of the lamp will automatically reduce to
25%.
