Operating Instructions
Powering On
Connect the power cord to the device's input port and then plug it into a standard electrical outlet. Locate the main power switch on the back of the device and flip it to the 'ON' position. You will hear a slight fan noise, indicating the device is powered on.
Selecting Light Modes
On the side panel of the device, you will find two separate switches: 'RED' for 660nm red light and 'NIR' for 850nm near-infrared light. You can activate either mode individually or both simultaneously. Note that near-infrared light (850nm) is not fully visible to the human eye, so the LEDs might appear off even when active.

Setting the Timer
The device features a built-in timer with preset options. Press the timer button to cycle through 5-minute, 10-minute, and 15-minute session durations. The device will automatically shut off once the selected time has elapsed.
Recommended Usage
For optimal results, position the device approximately 6 inches away from the target area. For superficial areas like the face, a session of 3-5 minutes is recommended. For deeper tissue treatment, such as joints or muscles, sessions of up to 10 minutes can be beneficial. Consistency is key; aim for daily use to observe noticeable improvements.

Understanding Red Light Therapy
Red light therapy, also known as photobiomodulation, uses specific wavelengths of light to stimulate cellular function. The 660nm (red) and 850nm (near-infrared) wavelengths used in the HG300 are absorbed by the mitochondria in your cells, leading to increased energy production and various therapeutic effects.
Key Benefits:
- Skin Health & Anti-Aging: Promotes collagen and elastin production, leading to smoother, more youthful-looking skin, reduced wrinkles, and alleviation of certain skin conditions.
- Pain Relief & Recovery: Helps reduce inflammation and provides relief from various types of pain, aiding in faster recovery from physical exertion.
- Improved Energy & Performance: Supports cellular energy production, which can lead to enhanced overall energy levels and improved physical performance.
- Enhanced Sleep & Mental Clarity: Regular use may contribute to better sleep patterns and improved cognitive function.
