2.2 Headlamp Adjustment

3. Operating Instructions
3.1 Power On/Off
To turn the headlamp on or off, press the large power button located on the top of the unit once.
3.2 Brightness Adjustment (Dimming)
With the headlamp on, hold down the large power button to adjust the brightness. The light will cycle through its brightness levels, flickering at the highest and lowest settings to indicate the limits.
3.3 Mode Selection
The Spot 350 offers multiple lighting modes for varying conditions:
- Distance Beam: Optimized for active situations and long-range visibility.
- Proximity Beam: Ideal for close-range activities like reading, cooking, or setting up camp.
- Red Night-Vision Mode: Preserves night vision and is useful for discreet use.
- Strobe Mode: For signaling or emergency situations.
To switch between different lighting beams, press the smaller mode button (if available, or cycle through with the main button depending on the specific model's interface). For models with two buttons, the smaller button typically cycles through modes.
3.4 PowerTap Technology
For instant maximum brightness, simply tap the PowerTap icon on the side of the headlamp. This feature allows for quick transitions to full power without cycling through modes.
3.5 Brightness Memory
The headlamp features Brightness Memory, meaning it will turn on at the last selected brightness level and mode, even if it was turned off from a different setting.
3.6 Digital Lockout Feature
To prevent accidental activation and battery drain when stored in a pack or pocket, the headlamp includes a digital lockout feature. To engage/disengage, hold down both the power button and mode button (or the single power button for single-button models) for approximately 3 seconds until the light flashes, indicating it is locked or unlocked.
3.7 Battery Meter
A six-setting, three-LED battery meter is located on the side of the front housing. This indicator displays the remaining battery life, allowing you to monitor power levels effectively.
