Operation

Switches

1. Master switch: controls on/off and output selection in General mode
2. Auxiliary switch: controls on/off and output selection in Flash mode

Product Instruction

• ON: With the light switched off, press and hold the Master switch for 0.5 seconds to enter General mode, press and hold the auxiliary switch for 0.5 seconds to enter Flash mode.
• OFF: With the light switched on, press and hold either the master or auxiliary switch to turn off the light.

Mode Selection

• In General mode, single-click the auxiliary switch to change to Flash mode.
• In Flash mode, single-click the master switch to change to General mode.

Output selection

• In General mode, single-click the master switch to cycle through Eco→Low→Med→High→Turbo.
• In Flash mode, single-click the auxiliary switch to cycle through Strobe→SOS.

Lock-out Function

• Lock: with the light unlocked, simultaneously press and hold the two switches for over 3 seconds. Light will switch off and 2 one-second blinks will indicate locked status.
• Unlock: with the light locked, simultaneously press and hold the two switches for over 3 seconds. The light will be unlocked and activated on last used brightness. In locked status, pressing any switch will activate 2 one-second blinks to indicate locked status.

Intelligent Memory Circuit

• The light memorizes the last selected brightness level on General mode.
• When turned on again the previously used brightness level will be recalled.

Intelligent Overheat Protection

• The light will accumulate a lot of heat when used on Turbo output level for extended periods.
• When a temperature of 65°C or above is reached, the light will automatically step down by a few lumens to reduce temperature.
• When the temperature is reduced, the output will gradually return to Turbo output level.

Battery Level Indication

There are four LEDs in the light tail. Single-clicking the round switch on the tail will indicate remaining battery level for 3 seconds: The more LEDs light up, the higher the battery level.

• Four LEDs on: more than 80%;
• Only one LED on: more than 20%
• One LED flashing: less than 20%

Low-voltage Warning

• When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached.
• When this happens in Eco output mode, the flashlight blinks three times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will only turn off once the battery over-discharging protection activates.

Charging

• First plug the USB terminal of the charging cable into an electrical outlet, then connect the Micro USB terminal of the charging cable to the light.
• The LED indicators will flash in sequence while charging, and will turn to constant on when fully charged. The normal charging time is approximately 4 hours.

Note:

1. Once charging is completed, be sure to close the anti-dust cover.
2. Recharge a stored light every four months to maintain optimum performance of the battery.

Battery Replacement

• Unscrew the tail cap to insert the battery (no need to check the polarity), then screw the tail cap back on.
• Remove the insulation sheet before first use.

Usage & Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare．
• Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
  • The batteries need replacing.
    • Solution: Replace batteries (Ensure batteries are inserted according to the manufacturer’s specifications).
  • The threads, PCB board contact or other contacts are dirty.
    • Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.

Warning

This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone’s eyes.

Troubleshooting

• Light flickers, shines intermittently, or fails to illuminate:
  • Check whether the batteries need replacing—replace with batteries inserted according to the manufacturer’s specifications.
  • If the problem persists, clean the contact points (threads/PCB board contact/other contacts) using a cotton swab soaked in rubbing alcohol.
• If the above methods don’t work: Contact your authorized distributor.
• Lock-out is enabled (light won’t behave normally):
  • To lock: simultaneously press and hold both switches for over 3 seconds (light turns off and 2 one-second blinks indicate locked status).
  • To unlock: simultaneously press and hold both switches for over 3 seconds; the light unlocks and activates on last used brightness. When locked, pressing any switch produces 2 one-second blinks to indicate locked status.
• Output steps down during long Turbo use: When temperature reaches 65°C or above, the light automatically steps down by a few lumens; as temperature reduces, output gradually returns to Turbo.
