Introduction
The Geemarc CL7400 Opti is an amplified TV headset designed to provide clear and powerful sound for individuals with hearing loss. This headset allows users to enjoy television programs without disturbing others, by amplifying audio directly to the headphones. It comes with a charging base and multiple connection cables (optical, RCA, Jack) to ensure compatibility with various audio sources. The headset is lightweight, foldable, and offers convenient controls directly on the earpieces for volume, balance, and tone adjustments. It also features an automatic power-off function to conserve battery life.
Setup
Before using your Geemarc CL7400 headset, ensure the charging base is properly connected to your audio source (e.g., television, radio, DVD player) and the headset is fully charged.
1. Charging the Headset
Place the headset onto the charging base. The charging indicator light on the headset will illuminate. A full charge takes approximately 6 hours and provides up to 8 hours of listening time. The headset can also be charged via a power bank or directly from a computer using a compatible cable (not amplified when used this way).

2. Connecting the Charging Base to Your Audio Source
The CL7400 base supports multiple connection types to ensure compatibility with most televisions and audio devices. Choose the appropriate cable based on your device's available audio output ports.
Optical Connection (Recommended for Digital Audio)
Use the supplied optical cable to connect the "OPTIC OUT" port on your television or audio device to the optical input on the CL7400 charging base. This connection provides high-quality digital audio.

RCA Connection (Analog Audio)
If your device has RCA audio outputs (red and white ports), use the supplied RCA cable to connect them to the corresponding RCA inputs on the CL7400 charging base. Ensure red connects to red (right channel) and white connects to white (left channel).

3.5mm Jack Connection (Analog Audio)
For devices with a 3.5mm headphone jack output, use the supplied 3.5mm audio cable to connect it to the corresponding input on the CL7400 charging base. This is common for older TVs, radios, or portable players.

Operating Instructions
1. Powering On/Off
Once the base is connected and the headset is charged, simply put on the headset. It should automatically connect to the base and receive audio. To turn off, place the headset back on the charging base or it will automatically power off after 4 minutes of no signal.
2. Adjusting Audio Settings
The CL7400 headset features intuitive controls located directly on the earpieces, allowing for personalized audio adjustments without needing to access the base or the audio source.
- Volume Control: Use the volume buttons (usually marked '+' and '-') on the headset to increase or decrease the overall listening volume. The headset can amplify sound up to 125dB SPL.
- Balance Control: Adjust the left/right audio balance to suit your hearing needs. This is particularly useful if you have different levels of hearing loss in each ear.
- Tone Control: Modify the audio tone (treble/bass) to enhance clarity for speech or music. This helps in making sounds sharper or richer based on preference.

3. Using with Smartphones and Other Devices (Direct Connection)
The CL7400 headset can be connected directly to devices with a 3.5mm audio jack, such as smartphones, MP3 players, or computers. When connected directly, the headset functions as a standard wired headphone and does not provide amplification. Amplification only occurs when the headset is receiving audio wirelessly from its charging base.
