Re: CISCO IP 7961G / External Speaker for Hard of Hearing
You can plug a PC-compatible powered speaker into the 3.5 mm Speaker jack on
the left side of the phone. External speakers can enhance the quality of the sound
that you hear from your phone.
To use an external speaker, you must configure the appropriate setting on the
Speakers menu on the phone
(choose Settings > User Preferences > Audio
Preferences > Speakers). For more information, refer to the Help available on the phone via the ? button.
Cisco recommends the following guidelines for external devices though:
The following information applies when you use external devices with the Cisco
Cisco recommends the use of good quality external devices (speakers, microphones, and headsets) that are screened against unwanted radio frequency(RF) and audio frequency (AF) signals.
Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:
â¢ Move the external device away from the source of the RF or AF signals.
â¢ Route the external device cables away from the source of the RF or AF
â¢ Use screened cables for the external device, or use cables with a better screen
â¢ Shorten the length of the external device cable.
â¢ Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no
control over the quality of external devices, cables, and connectors. The system
will perform adequately when suitable devices are attached using good quality
cables and connectors.
