Setup, Compatibility & Care
To set up your MH4, first ensure the battery is seated correctly. When using the included 14500 rechargeable battery, attach the magnetic charging cable to the base of the lamp head until the indicator lights up. The unit is compatible with any standard AA alkaline battery if you are on the go and lack a power source. To adjust the focus, rotate the lens bezel with one hand while the lamp is secured on the headband. To maintain your torch, wipe the exterior with a damp, soft cloth to remove dust or mud. Avoid using harsh chemical cleaners, as these can degrade the plastic housing. Since the device is IP54 rated, it is splash-proof, but you should dry it thoroughly after use in damp conditions to prevent moisture buildup near the contacts.
