Connect the supplied USB cable from the base station's USB port (Figure 2) to an available USB port on your PC. Your computer should automatically detect and install the necessary drivers.

3. Connect Headset (Not Included)

Connect your compatible EPOS Sennheiser DECT wireless headset to the base station according to the headset's specific instructions. Ensure the headset is charged and properly paired with the base station. Refer to your headset's manual for detailed pairing procedures.

4. Initial Configuration

The base station is designed for plug-and-play operation with PC VOIP systems, especially those certified for Skype for Business. For advanced settings, such as audio profiles or specific telephone system integrations, you may need to adjust the DIP switches on the side of the unit (Figure 3) or install the EPOS Connect software (available from the EPOS website).

Operating Instructions

Once set up, your base station facilitates seamless communication.

1. Making and Receiving Calls

When connected to your PC and a compatible VOIP application (e.g., Skype for Business), calls can be managed directly from your PC interface or via your paired headset's controls. The call control buttons on the front of the base station (Figure 1) may also be used for answering/ending calls, depending on your headset and software configuration.

2. Volume Control

• Listening Volume: Adjust the incoming audio volume via your PC's sound settings or your headset's dedicated volume controls.
• Microphone Volume: The microphone volume can be adjusted using the 'Mic. Vol.' knob located on the side of the base station (Figure 3). Rotate clockwise to increase volume, counter-clockwise to decrease.

3. Range and Connectivity

The DECT wireless technology provides a secure and stable connection. For optimal range and to minimize interference, ensure the base station is placed in an open area, away from large metal objects, microwave ovens, or other wireless devices operating on similar frequencies.

Maintenance

Proper care ensures the longevity and optimal performance of your base station.

1. Cleaning

Wipe the base station with a soft, dry, anti-static cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the surface and internal components.

2. Storage

When not in use for extended periods, store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
