Music-on-Hold requires either the 
SMOU PCB, which generates-electronic melo- 
dies, or a customer-provided external music 
source, such as an FM radio. If the SMOU is 
used, it must be installed per Paragraph 05.50. 
10.12 If an external music source is used for

Music-on-Hold, it’s output leads must be con- 
nected to the MOH terminals on the HKSU. 
10.13 Adjust the MOH volume with the MOH 
volume control on the HKSU. Maximum volume 
is limited by internal circuits in order to comply 
with FCC regulations. See Paragraph 10.70 for 
the correct volume setting sequence. 
10.14 Background music is provided via the 
same source as music-on-hold. Either the 
SMOU or an external source may be used. 
10.20 External Paging Coni;ections 
10.21 The system provides access to an exter- 
nal paging speaker. This speaker is also used for 
background music. The single output connection 
-34- 
- is made via the EXP or 600 terminals on the 
HKSU, and can be used in one of three ways: 
1) To operate a customer-provided speaker di- 
rectly via an internal 3-watt amplifier located 
on the SEPU PCB. 
2) If more than 3 watts are required, an exter- 
nal customer-provided amplifier can be con- 
nected to operate the external speaker (600 
terminal). 
3) If talkback capability is required, a customer- 
provided talkback amplifier/speaker can be 
connected (600 terminal).

10.30 Direct External Speaker Connection 
10.31 The exact number of speakers that may 
be connected to the 8-ohm, 3-watt output is de- 
pendent on the type of speaker used, conductor 
resistance, and desired volume. 
10.32 The 8-ohm output impedance must be 
selected with switch SW2 on the HKSU (Figure 
48). The switch must be on the side labeled 8. 
10.33 Connect the external speaker to the 
two 8/600 terminals on the left side panel ter- 
minal strip. 
10.34 Adjust the speaker volume with the 
EX.SP volume control on the left side panel. 
10.40 External Amplifier 
10.41 If more power is required than the 
SEPU amplifier can deliver, a customer-provided 
external amplifier may be connected to the 
8/600 terminals on the left side panel (connect 
external speakers to the external amplifier). 
10.42 Determine which output impedance is 
most suitable for the amplifier being used, and 
make the selection with SW2. 
10.43 If 8-ohm impedance is chosen, the 
EX.SP volume control may be used to control 
input level to the external amplifier. If 600-ohm 
impedance is chosen, the level is fixed and input

Paragraph 10.70 for the correct volume setting 
sequence. 
10.50 Talkback Amplifier 
10.51 A customer-provided talkback amplifier/ 
speaker may be connected to the external page 
(8/600) terminals on the left side panel. 
10.52 For talkback operation, SW2 must be 
set at “600”. The SEPU amplifier is not used for 
the 600-ohm mode in order to permit a 2-way 
voice path. 
10.53 The EX.SP volume control on the left 
side panel does not function in the 600-ohm 
7.;rje. 
10.60 Background Music 
10.61 BGM uses the music-on-hold program 
source that is connected to the MOH input ter- 
minals on the left side panel of the internal 
MOH source (SMOU). It is broadcast through all 
EKT speakers (under the individual control of 
each station user) and will be heard if the m 
/ key is operated with the handset on-hook and 
no line selected. 
10.62 As a programmable option, the BGM 
from the MOH source can be heard via the ex- 
ternal speaker (see Section 500-036-300, Pro- 
gramming Procedures). 
10.63 BGM is automatically pre-empted 
when a page or ringing signal must be output 
from an EKT speaker or the external speaker. 
10.64 ;jverail system E&M volume is set with 
the 
BGM volume control on the left side panel 
of the dKSU (see Paragraph 10.70 for the cor- 
rect volume setting sequence). The volume at in- 
dividual stations is set with the lower volume 
control on the right-hand side of the EKTs. 
10.65 If a separate BGM source is connected 
via an external amplifier on the external page, 
it can be heard from the external amplifier/ 
speaker only. If required, the system can provide 
a dry contact control signal for muting the exter- 
nal BGM when a page is in progress. 
10.66 To provide external BGM control, con- 
nect the BR terminals on the left side panel of 
the HKSU to the control terminals (mute, MIC 
switch, etc.) on the amplifier (see Figure 49).

1) Set the 
MOH volume control to its lowest 
level (counterclockwise). 
2) Lift the handset on one station and call an- 
other station using two CO/PBX lines. 
3) At the called station, put the incoming call 
on hold, and listen on the handset (not the 
speaker) of the calling EKT. 
4) Using the volume control on the MOH 
source, adjust MOH to the most comfortable 
level without distortion. - 
5) If a higher level is needed than can be pro- 
vided by the MOH source, turn the 
MOH vol- 
ume control slowly clockwise to achieve the 
most comfortable level without distortion.

6) Release the connection between the two CO 
lines. 
7) No further changes should be made using 
the 
MOH con$ol or the MOH source volume 
control. 
10.73 If an external speaker is to be used in 
the system, adjust the external page and BGM 
levels as follows: 
1) Adjustments should.be made while an actual 
external page test is in progress. Adjust the 
voice volume to 
a comfortable level. The 
procedure varies depending on the paging 
system configuration and the setting of the 
8i600-ohm switch (S&2): 
a) 8-ohm with no external amplifier-adjust 
output level using the 
EX.SP volume con- 
trol on the left side panel. 
b) 8-ohm with external amplifier-adjust out- 
put level using the 
EX.SP volume control 
along with the controls on the external am- 
plifier. 
c) 600-ohm-the volume level is fixed in this 
mode; adjustments must be made using 
the external amplifier controls. 
2) If background music is to be heard over the 
external speaker: 
a) Adjust voice page level per above proce- 
dures. 
b) With music playing over the speaker, ad- 
just the volume to a comfortable level us- 
ing only the 
BGM control on the left side 
panel of the HKSU. Do not tamper with 
the 
EX.SP control, external amplifier or 
MOH adjustT;lz;;% 
c) If background music is connected directly 
to the external amplifier instead of 
through the system, all adjustments must 
be made on the external amplifier. 
10.74 If no external speaker is to be used in 
the system, adjust the BGM level as follows: 
1) Using an EKT in speakerphone mode, make 
a call on a CO line, and adjust the EKT 
speaker volume to a comfortable level. 
NOTE. 
This should be done in an area that has 
background noise that is about average for 
tha-t particular installation. 
2) Using the m key, disconnect the CO call 
and activate BGM at the EKT. 3) Using only the 
BGM volume control, adju: 
the BGM to a comfortable level. Do not use 
the EKT volume control. 
10.80 Night Relay Service (Vle only) 
10.81 As an option, a dry contact can be pro- 
vided for the purpose of controlling an external 
loud ringing bell (or similar device) or an an- 
swering machine when the system is in the 
“NITE” mode. 
10.82 To provide this service, connect the ex- 
ternal device to the NR contacts on the left side 
panel (see Figure 51). 
RELAY 
CONTACTS 
FIGURE 51-RELAY CONTACTS 
IMPORTANT! 
The NR and BR relay contacts are rated at 
24 VDC/l amp and are not intended to op- . 
erate high power devices directly. If the 
power required for the device being con- 
trolled exceeds the contact ratings, an ex- 
ternal slave relay must be used. 
10.83 The W3 strap option on the VMAU (see 
Figure 52) allows the NR relay to function in one 
of two modes: 
1) Answering Machine Control-if the 
Wl strap 
remains intact, the relay is operated continu- 
ously when the system is in Night Service. 
This mode is intended for indirect control of 
an answering machine. 
2) Night Bell Control- if the W3 strap is cut, the 
relay pulses at a l-second on, 3-seconds off 
rate when the system is in Night Service and 
an incoming call is ringing the system. The 
mode is intended to be used for indirect con- 
trol of an external night bell.
