General Operation

The HC50 utilizes a 2-stage switch similar to a camera shutter button.
The light’s numerous functions are selected according to the depth the
switch is pressed.
With the light turned off, fully press and release within a second to turn
on. The brightness level displayed will be the last level that was used.
Repeat to turn off.

Brightness Selection

With the light turned on, press the switch half way down repeatedly to
cycle through the following output modes: ultra-low, low, medium, high
and turbo. A given brightness level will be memorized each time the light
is turned off while that level is displayed.
NB:

1. Medium brightness is the default brightness level when loading a
battery for the first time.

2. Every time the main white LED lamp is turned on, an integrated red /
green light will illuminate to indicate battery status. Please refer to the
“Power Tips” section of this manual for details.

Special Police Warning / SOS mode and
Location Beacon

With the light turned on, fully press the switch twice in quick succession
to turn on the police warning mode. Half press the switch repeatedly to
cycle through location beacon, SOS and police warning modes. Fully
press to exit special mode and turn the light off.

Red Light Illumination / Signal light

With the light turned off, press the switch all the way down and hold for
more than one second to enter into red light illumination mode (1.2
lumens).
When in red light mode, press the switch half way repeatedly to cycle
through red light signal mode and standard red light mode. Fully press
the switch to turn the light off.

Power Tips

Whenever the main lamp (white LED) is switched on, a power indicator
built into the switch will either illuminate or blink green or red to indicate
battery status.

1. When main light is turned on, the green power indicatior will illuminate
for two seconds when power levels are over 50%.

2. When main light is turned on, the red power indicatior will illuminate for
two seconds when power levels are below 50%.

3. With the main light turned on, the red power indicator will blink rapidly
when power levels are very low and the battery needs to be recharged
and replaced.

4. Each time a new battery is inserted, the green power indicator light will
blink in various sequences to indicate battery voltage (accurate to
±0.1V). For example, when battery voltage is at a maximum of 4.2V,
the power indicator will blink 4 times in quick succession, followed by a
one second pause and then two more successive blinks, indicating a
total battery voltage of 4.2V.

Thermal protection

As the HC50 is very compact, extended operation in turbo mode will
cause the body temperature to continually rise, thus making it too hot to
use comfortably. As a result, NITECORE does not recommend using the
HC50 in turbo mode for extended periods. To prevent overheating,the
HC50 will lower its output after three minutes' used of Turbo mode. The
HC50’s built-in thermal protection sensor prevents overheating and will
automatically reduce output when a temperature of 55°C is reached. This
function ensures user safety and protects the headlamp from failure /
damage.

Precaution: When the headlamp is hot, do not attempt to cool it by
submerging in liquid as differences in internal and external air pressure
may cause water ingress and irreparable damage.

Changing Batteries

When the power indicator blinks rapidly it means the batteries need to be
replaced or recharged. Alternatively if the light becomes dim or
unresponsive this also indicates batteries need to be replaced.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by
a thin coating of silicon-based lubricant.
