2. Setup
2.1 Battery Installation
The Apex headlamp requires four (4) AA batteries (included). Ensure correct polarity when inserting batteries.
- Locate the battery compartment on the rear of the headlamp.
- Open the battery compartment latch.
- Insert four AA batteries, matching the positive (+) and negative (-) terminals as indicated inside the compartment.
- Close the battery compartment securely until the latch clicks into place. Ensure the seal is tight to maintain water resistance.
2.2 Head Strap Adjustment
The headlamp features an adjustable elastic strap for a comfortable and secure fit.
- Place the headlamp on your head, ensuring the light unit is positioned at the front and the battery pack at the rear.
- Adjust the sliding buckles on the elastic strap to achieve a snug fit without being too tight.
- The top strap can also be adjusted for added stability, especially during high-impact activities.
3. Operating Instructions
3.1 Power On/Off
To turn the headlamp on or off, press and hold the main power button located on the top of the light unit.
3.2 Mode Selection
The Apex headlamp offers multiple lighting modes:
- Spot Beam: Provides a focused, long-distance beam. Press the main power button briefly to cycle through spot beam brightness levels (High, Medium, Low).

The headlamp typically remembers the last used setting when turned off and on again.
