Graphical display

White backlit, grayscale, 3.5-in. (9-cm) 396 x 162-pixel display

Handset

● Supports either a narrowband or a wideband audio handset connected through an RJ-9 port.

● All 6800 series handsets are Hearing-Aid-Compatible (HAC) and meet Federal Communications Commission (FCC) loudness requirements for the Americans with Disabilities Act (ADA). You can meet Section 508 loudness requirements by using industry-standard inline handset amplifiers such as Walker Equipment W-10 or CE-100 amplifiers. The dial pad on all 6800 series models is also ADA-compliant.

● The 6800 series handsets produce a magnetic field that attracts small metallic objects such as pins and staples. To avoid possible injuries, do not keep small metallic objects close to the handset.

Headset

● The 6800 series provides exceptional noise isolation when used with a Cisco Headset.

● The analog headset jack is a wideband-capable RJ-9 audio port

Backlit indicator

Volume control

A volume-control toggle provides easy decibel-level adjustments of the handset, monitor speaker, and ringer.

Full-duplex speakerphone

A full-duplex speakerphone gives you flexibility in placing and receiving calls. For added security, the Audible Dual-Tone Multi-frequency (DTMF) tones are masked when the speakerphone mode is used.

Single-position foot stand

The foot stand holds the phone in a single position, making the display easy to view and the buttons easy to use while sitting down. You can remove the foot stand for wall mounting. There are mounting holes located on the back of the phone.
