PRACTICE 512-6261-200
3. INSTALLATION
Location
3.01
For best acoustic performance, the
CONFER-
ENCE 2000 should be installed in a room which
does
not exceed 25 ft. (7 .6m) in length
or
width, with a
maximum
height of 9 ft. (2.7m). The walls, floor and
ceiling
should also be acoustically treated to minimize
echo
effect (i.e., carpet on floor, a hard surface ceiling,
drapery
covering windows, etc.).
3.02
The acoustic unit should
be
positioned a minimum
of 3 ft. (0.9m) from any wall and should
be
centrally
located on the conference table approxi-
mately
equidistant from all participants.
3.03
No participant should be more than 10 ft. (3.lm)
from
the acoustic unit. The surface of the table
directs the
voice
input; positioning the acoustic unit
on
a
pedestal adversely affects the performance of the
product.
Power
Supply
3.04
Input power to the CONFERENCE 2000 is
provided through a power supply comprising a
transformer
and a 12
ft.
(3.7 m) long, twerconductor
cord terminated by a power plug. The tranformer steps
the voltage down from 115 Vac to 16 Vac
and
is
capable
of delivering a current of 375mA. The power
plug connects into the
power
jack on the rear of the
control
module.
Connection to LOGIC Telephone Sets
3 .05 To connect the CONFERENCE 2000 to LOGIC-
type telephone sets proceed as follows:
( 1)
Hold the telephone set in the right hand with
the dial forward.

(2) Hold the control module in the left
hand
with
the face forward.
(3) Tilt the upper edge of the control module
towards the upper edge of the telephone
set
and bring the set and module togther so that the
plug is firmly in the socket.
Connection to SL-1 Electronic Telephone Sets
(LOGIC-style)
3.06 The CONFERENCE 2000 can be connected to
a LOGIC-style SL-1 set by following the procedure
outlined in 3.05. For proper operation however, it is
necessary to make minor wiring modifications to the
SL-1 set and add either a Q KK 1 E Handsfree lnterf
ace
Kit (A0283601) or a QKK3B Automatic Handsfree
Interface Kit (A0283608). When a QKK-type kit is
used,
external power to the control module
is
not
required; refer to Chart 3-5 of Practice 553-2001-211
for complete details
(Wiring
of the CONFERENCE
2000 is similar to the QUSlC LOGIC handsfree unit.)
3.07 For connection to other than LOGIC-type tele-
phone sets, including NE-500- and
NE-2500-type
SL-1 sets, the NE-D16QD mounting
cord
must
be
used. Refer to Tables B and C.
Connection to SM-1 Telephone Sets (LOGIC-style)
3.08 The CONFERENCE 2000 can
be
connected
to
a LOGIC-style SM-1 set
by
following
the
procedure outlined in 3.05. For proper
operation
however, it is necessary to make minor
wiring
modifications to the SM-1 set and
add a QKK2C
Interface Kit (A0272575). For
complete connection
instructions refer to Practice 502-8771-200
for the
SM-1 telephone set or Practice 518-8011-210
for the
SM-1 system. (Wiring of the CONFERENCE
2000 is
similar to the QUSlC LOGIC handsfree unit.)
