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 
mode. 
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 Overall system BGM volume is set with 
the BGM volume control on the left side panel 
of the HKSU (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). *Strata

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.

7) No further changes should be made using 
the MOH control or the MOH source volume 
control. 3) Using only the BGM volume control, adjust 
the BGM to a comfortable level. Do not use 
the EKT 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 
8/600-ohm switch (SW2): 
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.

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 
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. 
FIGURE 51-RELAY CONTACTS 
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 adjustments. 
The NR and BR relay contacts are rated at 
24 VDC/ 1 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. 
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. 10.83 The W3 strap option on the VMAU (see 
Figure 52) allows the NR relay to function in one 
of two modes: 
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. 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. 
NOTE: 
This should be done in an area that has 
background noise that is about average for 
that particular installation. 
2) Night Bell Control-if the W3 strap is cut, the 
relay pulses at a 1 -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. 
2) Using the m key, disconnect the CO call 
and activate BGM at the EKT.
