Common Issues:

Laser does not power on:

    • Make sure battery is the proper model, voltage and current rating as specified on laser purchase page.
    • Clean driver contact pad. (positive battery PCB connection may still have residue from factory)
    • Bypass tail switch using a metal object. (jumping battery negative directly to host). If the laser powers on, the switch is faulty. Contact us for a free replacement.
    • Test battery voltage with a voltmeter. (should read between 3.8v-4.2v).
    • If the battery has been inserted backwards, the driver may be damaged. Send us a message for a repair.

Laser weak output:

    • Make sure battery is the proper model, voltage and current rating as specified on laser purchase page. (ex. Saft brand batteries are known to be weak)
    • Test battery voltage with a voltmeter (should read between 3.8v-4.2v)
    • If battery is from a reputable seller, and of correct voltage/current rating and the laser is still a dim output, the laser likely requires repair.

Laser flashing:

    • A flashing/blinking laser could mean a low battery voltage. Test with a new, freshly charged battery.
    • A flashing/blinking laser could mean driver over-temp condition. Let the unit cool down before use.

Bad laser beam:

    • REMOVE THE BATTERY BEFORE ATTEMPTING ANY ADJUSTMENT!
    • Turning the lens does not change focus; remove the knurled thumb screw completely, then remove the lens. Screw both together, then reinstall lens components in reverse.
    • A large circular beam; may mean the lens is simply out of focus. It can be manually adjusted by twisting the front thumb screw. Be gentle to avoid damage .
    • A strange wave pattern means the acrylic lens has melted. The lens will need replacement. Avoid burning up close and always keep the lens clean.
    • A spotted laser beam; with artifacts may mean the lens is dirty or has been damaged. Clean the lens gently with a clean cotton swab and isopropyl alcohol.
    • A line instead of a dot; may be normal. Some of our products use multi-mode diodes which have large "divergence" at long distances.
