System Telephones on the Forum 500 / Forum 5000
z
Forum Phone 520 and Forum Phone 530 can each be
expanded by various types of external
audio equipment
, e.g.
a headset or an external active speaker.
Connection is via an audio adapter.
Please refer to the chapter entitled
External Audio Devices
starting on page 32.
The operating range of such add-ons depends on the maximum
power of the U
pn
interface of the communications system, and on
the power consumption of the respective equipment. The range
can be increased by the deployment of secondary AC adapters.
For the relevant technical details and a complete overview of the
various equipment combinations that you can configure, please
refer to the chapter entitled “Accessories and Adapters” in the
“Mounting and Commissioning” (Forum 523/524, Forum 525/526,
Forum 550/560) resp. “Commissioning and Maintenance”
(Forum 5050) user guide. Please also refer to the information on
the scope of available features in expanded equipment combina-
tions.
Note:
Secondary devices are activated by the communications
system. The communications system detects whenever there are
two adapters of the same type on a Forum Phone 530. This is not
permitted, and for this reason, they are not released for opera-
tion.
CAUTION! Protect your equipment against static dis-
charge!
Static electricity can damage the sensitive components of the
Forum 500 / Forum 5000. To avoid such damage when connecting
add-ons, you must first discharge the static electricity from your
body. Work only in an antistatic environment. If possible, use con-
ducting pads or antistatic mats.
