Distance Limitations
The maximum allowable distances of a 7205H voice terminal from the System 85
and the DEFINITY G2 cabinet are shown in the following table.
Power Requirements
The 7205H voice terminal is powered by the tip and ring leads. If the 7205H is
equipped with the S101A speakerphone or the 500A headset adapter, auxiliary
power will be required for the adjunct. Refer to the Adjunct Power section earlier
in this manual.
The C201A call coverage module attaches to the top of the voice terminal, and the
F201A function key module attaches to the right side. These optional modules use
the same phantom power from the switch (through the digital pairs) that also
powers the 7205H voice terminal. This impacts the distance allowed from the
switch.
Power Failure Operation
The 7205H voice terminal cannot be used as an emergency station during power
failure transfer conditions.
FCC Registration
The 7205H voice terminal is not FCC registered.
Hearing Aid Compatible
The 7205H voice terminal is compatible with the inductively coupled hearing aids
prescribed by the FCC.
