2. Setup
2.1 Battery Installation
The Onnight 100 Headlamp operates on 3 AAA (LR03) alkaline batteries, which are included with the product. To install or replace batteries:
- Locate the battery compartment on the back of the headlamp body.
- Gently peel back the flexible SEBS casing to access the battery cover.
- Open the battery cover and insert the 3 AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery cover securely and re-position the SEBS casing to protect the headlamp from impacts and rain.
The monobloc construction ensures optimal compactness while the flexible casing allows easy battery access.
3. Operating Instructions
3.1 Light Modes
The Onnight 100 Headlamp features 3 distinct lighting modes, suitable for various situations:
- Red Mode: Ideal for maintaining night vision or for discreet use in a shelter.
- Economic Mode: Suitable for walking or camping activities, providing extended battery life.
- Strong Mode: Designed for walking on trails, offering maximum illumination.
3.2 Switching Between Modes
The headlamp's switch is designed for easy manipulation, even when wearing gloves. Press the power button repeatedly to cycle through the different light modes. A single press typically turns the unit on or off, and subsequent presses change modes.
The classic LED lighting technology means that the illumination performance will progressively decrease as the batteries discharge, ensuring longer autonomy.
4. Maintenance
4.1 Strap Care
The headlamp strap is detachable and washable. To clean:
- Carefully detach the strap from the headlamp body.
- Wash the strap by hand with mild soap and water.
- Allow the strap to air dry completely before reattaching it to the headlamp.
The strap is composed of 70% polyester and 30% natural rubber for maximum comfort. The symmetrical double buckle adjustment system facilitates easy tightening and ensures the headlamp fits all head sizes, from children to adults, as well as mountain helmets.
4.2 General Care and Storage
- Wipe the headlamp body with a clean, damp cloth if it gets dirty. Do not use abrasive cleaners.
- If the headlamp will not be used for an extended period, remove the batteries to prevent leakage and potential damage to the device.
- Store the headlamp in a cool, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
If you encounter issues with your FORCLAZ Onnight 100 Headlamp, please refer to the following common solutions:
- Headlamp not turning on: Check if the batteries are inserted correctly with the right polarity. Replace old batteries with new ones.
- Dim light output: This is normal as batteries discharge. Replace batteries if the light is too dim for your needs.
- Intermittent light: Ensure battery contacts are clean and free of corrosion. Re-insert batteries firmly.
