Setup

1. Battery Installation

The VASTFIRE A100 flashlight can be powered by either one 18650 rechargeable battery or three AAA batteries using the provided AAA battery holder.

Unscrew the tail cap of the flashlight.
For 18650 Battery: Insert one 18650 battery with the positive (+) end facing towards the flashlight head.
For AAA Batteries: Place three AAA batteries into the AAA battery holder, ensuring correct polarity. Insert the loaded battery holder into the flashlight with the positive (+) end facing towards the flashlight head.
Screw the tail cap back on securely.

Diagram showing how to install batteries: either three AAA batteries in a holder or one 18650 battery directly into the flashlight body. — Figure 8: Battery installation options.

2. Charging the 18650 Battery (if included)

If your kit includes an 18650 rechargeable battery and charger:

Insert the 18650 battery into the designated slot on the charger, observing correct polarity.
Connect the charger to a suitable USB power source (e.g., wall adapter, computer USB port).
The charger's indicator light will typically show red during charging and turn green when fully charged.
Once charging is complete, disconnect the charger and remove the battery.

3. Attaching the Rifle Scope Mount

The "8" type scope mount allows you to attach the flashlight to a rifle scope or other compatible rail systems.

Identify the two rings on the mount. One is for the flashlight body (28.5mm diameter) and the other for the rifle scope or rail (25mm & 24.7mm diameters).
Loosen the screws on both rings using the provided mini hexagon spanner.
Carefully place the flashlight into one ring and your rifle scope/rail into the other.
Adjust the position as desired and tighten the screws firmly to secure the flashlight and scope/rail. Ensure the mount is stable and does not obstruct your view or operation.

Operating Instructions

1. Power On/Off

Press the button on the tail cap to turn the flashlight ON or OFF. The A100 features a single high-power mode.

2. Adjusting Focus (Zoom Function)

The VASTFIRE A100 features an adjustable focus system to change the beam from a wide floodlight to a concentrated spotlight.

To Zoom In (concentrate the beam), extend the head of the flashlight forward. This creates a tighter, more focused beam for long-range illumination.
To Zoom Out (widen the beam), retract the head of the flashlight backward. This creates a broader, less intense beam for wider area illumination.

Maintenance

1. Cleaning

Wipe the flashlight body with a soft, damp cloth to remove dirt and debris.
For the lens, use a lens cleaning cloth and a small amount of lens cleaning solution to avoid scratches.
Do not use abrasive cleaners or solvents, as they may damage the finish or lens.

2. Battery Care

Always use high-quality batteries.
If using rechargeable 18650 batteries, ensure they are fully charged before extended use and recharge them regularly.
Remove batteries from the flashlight if it will not be used for an extended period to prevent leakage and damage.
Store batteries in a cool, dry place.

3. Water Resistance

The A100 flashlight is splash-proof only. Do not submerge it in water or expose it to heavy rain. Ensure all caps and seals are tightly closed before use in damp conditions.
