5. ઓપરેટિંગ સૂચનાઓ
5.1 પાવર ચાલુ/બંધ
To turn the flashlight on or off, press the button on the tail cap. A full press will toggle the power.
5.2 Focus Adjustment (Zoom Function)
The flashlight features a telescopic lens for adjusting the beam width:
- Zoom In (Spotlight): Extend the head of the flashlight forward to narrow the beam. This concentrates the infrared light for longer-range illumination, clearly illuminating objects well past 164 yards.
- Zoom Out (Floodlight): Retract the head of the flashlight backward to widen the beam. This spreads the infrared light to cover a larger area for broader observation.

આકૃતિ 2: An illustration demonstrating the telescopic focusing feature of the DARKBEAM 501F. It shows the flashlight in both 'zoom in' (narrow beam) and 'zoom out' (floodlight) positions, with corresponding images of a squirrel showing the effect on illumination area and intensity. Dimensions of the flashlight in both states are also provided.
5.3 Usage with Night Vision Devices
The DARKBEAM 501F is designed to work in conjunction with professional infrared equipment. It will not produce visible light for the naked eye. To utilize its full potential, pair it with:
- Night vision scopes
- મોનોક્યુલર્સ
- Infrared cameras
- Night vision goggles
When used with compatible night vision devices, the 940nm infrared light will illuminate your target area, allowing for clear observation in complete darkness.

આકૃતિ 3: An image illustrating the characteristics of the 940nm LED, noting it is almost invisible to the naked eye and requires professional night vision equipment for use. It shows the flashlight, a close-up of the LED when off, and a faint red glow when on (visible via mobile phone camera), along with icons for infrared cameras, goggles, and a coyote, indicating its application.

|---|---|---|
| ફ્લેશલાઇટ ચાલુ થતી નથી. | બteryટરી યોગ્ય રીતે ઇન્સ્ટોલ કરેલી નથી. | Ensure the battery is inserted with the correct polarity (+ end towards the head) and the tail cap is fully tightened. |
| બેટરી ખતમ થઈ ગઈ છે. | Charge the battery fully using the provided USB charger. | |
| Tail cap is loosened. | યોગ્ય વિદ્યુત સંપર્ક સુનિશ્ચિત કરવા માટે પૂંછડીની ટોપીને સજ્જડ કરો. | |
| No visible light from the flashlight. | This is an infrared flashlight. | The 940nm light is invisible to the naked eye. It requires a night vision device (scope, monocular, camera, goggles) to be seen. A faint red glow might be visible directly on the LED itself, or through a mobile phone camera. |
| Weak or inconsistent illumination through night vision device. | બેટરી ઓછી છે. | બેટરી રિચાર્જ કરો. |
| લેન્સ ગંદા છે. | લેન્સને સોફ્ટ કપડાથી સાફ કરો. | |
| Flashlight gets hot during use. | સામાન્ય કામગીરી. | Some heat generation is normal during operation, especially during prolonged use. If it becomes excessively hot, turn it off and allow it to cool. Ensure proper ventilation. |
