Q: How does the HM23 V2 lockout function work?

Lock: with the lamp switched off, press and hold the switch for 3 seconds, the lamp will blink red 4 times to indicate locked status. 

Unlock: with the lamp locked, press and hold the switch for 3 seconds, the lamp will be activated on the Low output of White light mode after blinking red 4 times to indicate the unlocked status. 

In the locked status, a single click or double click of the switch will activate 4 red blinks to indicate the locked status.

*Note: With the light locked, even if you remove and re-insert the battery, the light will not be unlocked automatically. 

Q: Why does the HM23 V2 downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: Low-voltage Warning

When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until the lowest output is reached. When this happens in the lowest output, the lamp blinks 3 times every 5 minutes to remind users to replace the battery. 

Q: Why does the HM23 V2 flicker?

A: The reasons that may cause the lamp to flicker, shine intermittently or even fail to illuminate:

A: Poor battery level.

Solution: Replace the battery.

B: The contact point or contact of the battery or headlamp is dirty. 

Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact the distributor.
