Key Phone Wall Mounting
Guidelines
• DBS 576 key phones can be mounted on the wall using the wall mounting adapter 
on the bottom of the phone.
Installation
1.  Remove the wall mounting adapter from the bottom of the phone taking care not 
to damage the adapter hooks.
2.  Rotate the wall mounting adapter by 180 degrees, then slot it into the two 
guides.
3.  Remove the handset guide, rotate it by 180 degrees, and replace it.
4.  Insert two screws in the wall.
5.  Hook the two mounting holes on the bottom of the phone onto the two screws in 
the wall.

Chapter 6. Peripheral Equipment
This chapter describes how to install and connect DSS, doorphone adaptors, other 
peripheral equipment, and replacing the backup battery of CPC card.
Music-On-Hold (MOH)
Guidelines
• A music source such as a CD player or tape recorder can be connected to the 
MOH input of a CPC96, CPC288, or CPC576 card installed in the CPC slots of 
the cabinet to provide music-on-hold (MOH).
• CPC96, CPC288, and CPC576 cards cannot be installed and removed while the 
cabinet is operating. First, turn the power off.
• The maximum input impedance of the MOH input (CN4: RCA) is 10k
 Ohms. The 
maximum input signal level is -10dB.
Installation
1.  Connect one end of an RCA pin cable (2-core shielded cable) to the CN4 (RCA) 
connector on the CPC96, CPC288, or CPC576 card.
2.  Connect the other end of the RCA pin cable to the output (AUX) of a music 
source such as a CD player or tape recorder.
Fit the appropriate connector (RCA or mini-plug, etc.) as required to the 
end of the RCA pin cable to suit your music source.

Background Music (BGM)
Guidelines
• A music source such as a CD player or tape recorder can be connected to the 
BGM input (RCA) of an SCC card installed in one of the optional card slots of the 
cabinet to provide background music (BGM).
• SCC cards cannot be installed and removed while the cabinet is operating. First, 
turn the power off.
• If an FM radio is connected as a music source, it must be located at least 16.5 ft. 
(5m) from the cabinet.
• The maximum input impedance of the BGM input (CN4: RCA) is 10k
 Ohms. The 
maximum input signal level is -10dB.

576-13-300 DBS 576 (USA), issued 6/2/98 6-3 
Installation
1.  Install the SCC card in an available optional card slot.
2.  Connect one end of an RCA pin cable (2-core shielded cable) to the CN4 (RCA) 
connector on the SCC card.
3.  Connect the other end of the RCA pin cable to the output (AUX) of a music 
source such as a CD player or tape recorder.
Fit the appropriate connector (RCA or mini-plug, etc.) as required to the 
end of the RCA pin cable to suit your music source.

Paging
Guidelines
• Paging can be performed by connecting a paging amplifier, relays, and speakers 
to an SCC card installed in one of the optional card slots.
• SCC cards cannot be installed and removed while the cabinet is operating. First, 
turn the power off.
• The paging amplifier, relays, and speakers are not provided with the DBS 576 and 
must therefore be purchased separately.
• Table 6-1 shows the pinout of the external connector (CN3) of the SCC card.
Table 6-1.  Pinout of external connector (CN3) of SCC cardCAUTION:
• Turn the power switch and the external breaker OFF, and disconnect the 
AC cable before installing the Paging equipment.
