Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Accessories
Bluetooth Accessories
Users can pair Bluetooth accessories, such as headsets, keyboards, and mobile phones, to their DX Series devices.
Users can pair multiple Bluetooth devices at one time, however they may only pair one Bluetooth audio device at a time.
Enabling Bluetooth may degrade a wireless network connection. For improved wireless network performance, users should disable Bluetooth when it is not in use, or use the 5 GHz band for their wireless network connection.
Bluetooth Device Profiles
The Device Profile Settings screen shows the profiles that are available for a paired device. If you disable a profile, the profile is unchecked and the user cannot enable it.
Handsfree Profile
Cisco DX Series devices support various Handsfree Profile features that enable you to use accessories (such as Bluetooth wireless headsets and Bluetooth-capable mobile phones) to perform certain tasks without the need to handle the device. For example, rather than tap Redial on the device, users can follow instructions from the headset manufacturer to redial a number from their Bluetooth wireless headset.
These hands-free features apply to Bluetooth accessories:
Handle Bluetooth HFP connected/disconnected status.
Dial a phone number on the Audio Gateway (AG) to make a call.
Indicate when a call is connected or disconnected.
Notify an application when a call is incoming (inband ringtone).
Enable or disable inband ringing.
Report phone status (such as caller ID, signal strength, and battery level, from the AG).
Answer or reject calls.
Receive call-waiting notification with caller ID.
Put a call on hold and switch to a waiting call.
Switch between calls on hold and active calls on the AG and in the Call application.
Switch audio to the mobile phone and return audio back to the Hands-Free Unit.
Retrieve the mobile phone call list.
Hands-free devices may differ as to how features are activated. Device manufacturers may also use different terms to refer to the same feature. For more information, see the manufacturer documentation.
Phone Book Access Profile
Bluetooth Phone Book Access Profile (PBAP) allows the user to share contacts and call history from a paired mobile phone to a Cisco DX Series device. The user can choose to download contacts and call history manually or automatically when they pair their mobile phone, and can choose to save the contacts on their device.

Cable Lock
You can use a laptop cable lock to secure the device to a desktop. The lock connects to the antitheft security connector on the back of the device and the cable can be secured to a desktop.
The security slot can accommodate a lock up to 20 mm wide. Compatible laptop cable locks include the Kensington laptop cable lock and laptop cable locks from other manufacturers that fit into the security slot on the back of the device.
External Cameras
Cisco DX650 supports the add-on Logitech C920-C Webcam or Logitech C930e as an external camera.
The external camera connects to the device and allows the user to make a point-to-point video calls. For the external camera to work, video calling and USB devices must be enabled.
 Note | If the Cisco DX650 is powered by Power over Ethernet, the external camera requires 802.3at. If the phone is not powered by Power over Ethernet, the external camera requires an external power supply. |
External Camera Settings
After you attach the external camera to the device, the user can control the settings of the external camera. Unlike the internal camera, the brightness setting for the external camera cannot be adjusted.
Perform External Camera Postinstallation Checks
.External Speakers and Microphone
External speakers and microphones are plug-and-play accessories. You can use the line in/out jack to connect an external PC-type microphone and powered speakers (with amplifier) on the device. Connection to an external microphone disables the internal microphone, and connection to an external speaker disables the internal speaker.
Note | Use of poor-quality external audio devices, use of loudspeakers at very loud volumes, or placement of the microphone very close to the loudspeaker may result in undesirable echo for other parties on your speakerphone calls. |
Headsets
Although Cisco performs internal testing of third-party headsets, Cisco does not certify nor support products from headset or handset vendors.
The device reduces some background noise that a headset microphone detects, but if you want to further reduce the background noise and improve the overall audio quality, use a noise-cancelling headset.
Cisco recommends the use of good-quality external devices, for example, headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Due to the quality of headsets and their proximity to other devices, such as mobile (cell) phones and two-way radios, some audio noise or echo may still occur. Either the remote party or both the remote party and the user may hear an audible hum or buzz. A range of outside sources can cause humming or buzzing sounds; for example, electric lights, electric motors, or large PC monitors.
Note | In some cases, use of a local power cube or power injector may reduce or eliminate hum. |
These environmental and hardware inconsistencies in the locations where devices are deployed mean that no single headset solution is optimal for all environments.
Cisco recommends that customers test headsets in the intended environment to determine performance before purchase and deployment on a large scale.
Note | Only one headset type works at any given time, so if you use both a Bluetooth headset and an analog headset that are attached to the device, when you enable the Bluetooth headset you disable the analog headset. To enable the analog headset, disable the Bluetooth headset. When you plug a USB headset into a device that has Bluetooth headset enabled, you disable both the Bluetooth and analog headset. If you unplug the USB headset, you can either enable the Bluetooth headset or disable the Bluetooth headset to use the analog headset. |
Bluetooth Wireless Headsets
The device uses a shared key authentication and encryption method to connect with Bluetooth headsets. The device can connect with up to five headsets at a time. The last connected headset is used as the default. Pairing is typically performed once for each headset.
After a device is paired, the Bluetooth connection is maintained as long as both the device and headset are enabled and within range of each other. The connection typically reestablishes itself automatically if either of the devices powers down then powers up. However, some headsets require user action to reestablish the connection.
Wideband for Bluetooth headsets is not supported. Voice quality may be reduced when using Bluetooth headsets.
The best performance is in the 3- to 6-foot range (1 to 2 meters). You can pair five or more headsets, but only the last headset that was connected is used as the default. When headsets are more than 30 feet (10 meters) away from the device, Bluetooth drops the connection after a 15- to 20-second timeout. If the paired headset comes back into device range and the device is not connected to another Bluetooth headset, the in-range Bluetooth headset automatically reconnects. For certain devices that operate in power-save modes, the user can tap the operational button to initiate the reconnection and wake up the headset.
Potential interference issues can occur. Cisco recommends that you reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal objects. If possible, configure other 802.11 devices to use the 802.11a channels.
For a Bluetooth wireless headset to work, the headset does not need to be within direct line-of-sight of the device, but some barriers, such as walls or doors, as well as interference from other electronic devices, can affect the connection.
For more information about Bluetooth headsets, see the user guide that is provided with the headset.

Wired Headsets
Cisco DX70 and Cisco DX650 support 3.5 mm single-plug headsets. The user can place and answer calls with the headset.
Connect to Wired Headset
Disable Wired Headset
You can use Cisco Unified Communications Manager Administration to disable the headset. If you do so, you also disable the speakerphone.
Video Displays
Cisco DX650 supports external display devices through the HDMI port. Connect a monitor to the device by inserting one end of an HDMI cable into the HDMI port and the other end into a monitor HDMI port.
Cisco DX650 Wall-Mount Kit
To mount the Cisco DX650 on the wall, use the special brackets that are available in a Cisco DX650 wall-mount kit. Wall-mount kits must be ordered separately from the device.
