Backup battery

FCC compliance
statement
The QC100 utilizes an internal battery to maintain system con-
figuration settings during power interruptions. A battery circuit
charges this backup battery during periods of normal operation.
When the QC100 is used on a daily basis, the backup battery will
be adequately charged to maintain configuration settings during
power outages. However, over extended periods of nonuse, the
battery might lose the charge necessary to maintain configura-
tion settings. To keep the backup battery charged over extended
periods of nonuse, apply power to the QC100 and leave it turned
on for a minimum of 2 days each month.
FCC Rule NP15R Rev. 23, June, 1989
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used
in accordance with the instructions in this guide, may cause harmful
interference to radio communication. Operation of this equip-
ment in a residential area is likely to cause harmful interference, in
which case the user will be required to correct the interference at
his own expense.
Shielded cables must be used with this unit to ensure compliance
with Class A FCC limits. The connection of a nonshielded equip-
ment interface cable to this equipment will invalidate the FCC Cer-
tification of this device and may cause interference levels which
exceed the limits established by the FCC for this equipment. It is
the responsibility of the user to obtain and use a shielded equip-
ment interface cable with this device. Do not leave cables con-
nected to unused interfaces. Changes or modifications not ex-
pressly approved by the manufacturer could void the user’s au-
thority to operate the equipment.
