FCC INFORMATION
This telephone has been tested and found to comply with all applicable UL
and FCC standards. This product’s design enables it to be connected to most
telephone lines. However, each device you connect to the telephone line
draws power. This power draw is known as the Ringer Equivalence Number
(REN) which is identified on the bottom of the telephone. If you use more
than one telephone or other device on the line, add up all the RENs. If the
total is more than 5.0, your telephone(s) may not ring and your answering
machine might not answer. When used behind a PBX, the total number of
devices that may be connected will be dependent on the PBX used. If the
telephone doesn’t ring, remove one of the devices from the line.
This telephone complies with Part 68 of FCC Rules. Upon request by your
telephone company, you must provide the FCC registration number and the
REN. These numbers are both located on the bottom of your telephone. The
telephone must not be connected to: 1) coin-operated systems, 2) party-line
systems, and 3) electronic key telephone systems that do not have standard
analog telephone extension ports.

activities. You can choose to connect the speakerphone to as many as four
telephone lines. The speakerphone can be connected to two 2-line (RJ14C)
modular telephone jacks to accommodate all four lines.
If you install more than one speakerphone, ensure that they are all connected
to the same Line 1 wiring. During initialization and before the speakerphone
is programmed, the telephone will continuously ring and display “EXT 00”.
This is a reminder to program the desired intercom extension number (11-40)
before connecting additional telephones. Refer to the Programming section to
set the extension number. The telephone will operate without batteries
however, batteries should be installed for memory backup.
2. Configuration
The DCTS-900 system consists of cell units, wireless handsets, and
Executive Speakerphones. Each cell unit provides two (2) talk channels for
intercom and outside calls. You can use a maximum of twelve (12) Executive
Speakerphones.
3. Installing the Executive Speakerphone
You can choose from two (2) installation options:
nlocate the telephone on a desk or tabletop, or
nmount the telephone on the wall.
3.1 Desk/Tabletop Mounting
You can install the telephone with the desk/wall stand or you can use the
elevator stand which tilts the telephone to provide a higher profile. You will
need to locate the telephone near a standard 120V AC outlet.
1. Turn the speakerphone over to view the bottom. Remove the screw from
the battery compartment.

2. Remove the battery compartment cover by pushing in the tab and lifting.
Locate the batteries packed with the telephone and install the batteries.
Ensure that correct polarity is maintained as indicated by the “+” and “-”
markings inside the compartment and on the batteries.
Note: Use three (3) AAA batteries only. The batteries maintain the
telephone memory in the event of an extended AC power failure.
3. Snap on the battery compartment cover and tighten the screw.
4. Remove the desk/wall stand by pressing and lifting the two tabs at the
top of the stand.

10

the stand into the slots on the bottom of the telephone (rubber feet on the
stand are positioned at the top of the telephone). Push on the rubber feet
to snap the stand into place.

outlet. The display briefly shows “INITIALIZING…” , and the
telephone will ring until an extension number has been
programmed.
11. Ensure that all cords are positioned to prevent tripping and rubbing
which could create a potential electrical hazard.

two screws and washers provided. Then the desk/wall stand is installed on
the telephone in the wall mode.

elevator stand into the hole on the desk/wall stand (ensure that the
rubber feet on the desk/wall stand are aligned with the two recessed
areas on the elevator stand).
