The operating range of such add-ons
depends on the maximum power of
the U interface on the communi-
pn
cations system, and on the power
consumption of the respective
equipment. The range can be in-
creased by the deployment of sec-
ondary AC adapters. For the relevant
technical details and a complete
overview of the various equipment
combinations that you can config-
ure, please refer to the chapter enti-
tled "Accessories and Adapters" in
the Mounting and Commissioning
User Guide. Please also refer to the
information on the scope of availa-
ble features in expanded equipment
combinations.
Note: Secondary devices are acti-
vated by the OpenCom 100. The
OpenCom 100 recognises when there
are two adapters of the same type on
an OpenPhone 65, because this is not
permitted. For this reason, they are
not released for operation.
CAUTION! Protect your
equipment against static dis-
charge!
Static electricity can damage the
sensitive components of the
Add-ons (with & without Adapters)
