Operating Instructions
1. Powering On/Off
Press and hold the power button (usually located on the top or side of the unit) for a few seconds to turn the device on or off.
2. Adjusting Infrared (IR) Illumination
The Nightfox Swift uses infrared illumination to enhance visibility in low light or complete darkness. Use the dedicated IR buttons to cycle through different IR levels or turn it off. Higher IR levels provide brighter images but consume more battery.
