Headset safety

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system performs adequately when you use good-quality cables and connectors to attach suitable devices.

Caution In European Union countries, use only external speakers, microphones, and headsets that are fully compliant with the EMC Directive [89/336/EC].

Headset safety

When you use a headset, set the volume to a safe level. Permanent hearing loss or damage may occur if you use a headset at high volume.

Do not use a headset at high volume to block out other noise. Lower the volume if you cannot hear people speaking near you.

If you experience ringing in your ears, muffled voices, or other signs of hearing loss or damage, stop using your headset and have your hearing checked.

Bluetooth wireless headset performance

Cisco DX600 Series phones support Bluetooth Class 2 technology when the headsets support Bluetooth. Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best performance is in the 3- to 6-foot (1- to 2-meter) range. You can connect up to five headsets, but only the last connected headset is used as the default.

Because potential interference issues can occur, Cisco recommends that you move 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal objects away from the wireless headset.

For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone. Some barriers, such as walls or doors, and interference from other electronic devices, can affect the Bluetooth connection.
