11. Disconnect the instrument mounting cord. 
Remove the wall mount adapter (baseplate) 
from the bottom of the keyset. 
Remove the modular shorting plug from the 
modular jack in the base of the keyset. 
Insert the external speaker modular plug into 
this jack. 
Remove the woodgrained faceplate by pushing 
the spring-loaded tab at the top of the faceplate 
backwards, and lifting the top of the faceplate. 
Carefully bend the two locking tabs which 
protrude through the top of the keyboard and 
LED assembly; lift the board; and slide forward. 
Lift the board out of the keyset assembly. 
Locate the DIP switch assembly. (Refer to 
Figure 3-13.) 
Enable the full-duplex speakerphone DIP 
switch. (Refer to Figure 3-l 1.) 
Reassemble the keyset. 
Reconnect the keyset mounting cord. To install the DSS/BLF (model 3030D or 35320) 
proceed as follows: 
1. 
2. 
3. 
4. 
5. 
6. 
7. Remove the wall mount adapter (baseplate) 
from the DSS/BLF. 
Connect one end of the 24-inch 3-pa.ir cable to 
the receptacle labeled “TO STA,” and a 6-foot 
power cable to the receptacle labeled “TO 
POW.” (Refer to Figure 3-14.) 
Install the 3-pair cable and the power cable as 
shown in Figure 3-14. 
Remove the modular connector located on the 
rear of the keyset and connect it to the connector 
labeled “From KSU” on the DSSIBLF. 
Connect the 24-inch 3-pair cable to the keyset. 
Attach the spade lugs on the DSS/BLF power 
cable to the screw connectors marked “LOAD” 
on the step-down transformer supplied with the 
DSS/BLF. 
Connect the step-down transformer to a 117 
VAC 60 HZ outlet. 
6.02 installation with Optional System Battery 
Back-Up or Without an AC Outlet. 
For a system’with optional system battery back-up, 
or for a system without access to an AC outlet, 
perform the following: 
1. From the base of the DSS/BLF, remove the 
transformer and the transformer power cable. 
(See Figure 3-15 or 3-16.) 
2. From inside the DSS/BLF, remove the two-wire 
power connector from the housing labeled “TO 
POW.” 
3. Complete the removal of the power connector 
by removing the red wire and the green wire 
from connectors 13 and 14. 
4. Run jumpers from connector 1 to connector 13 
and from connector 2 to connector 14.

6.03 Voltage Regulator Setting B. Any station may perform an all page. 
1. Disassemble the DSWBLF 
2. Measure the voltage across CR4 with a DVM. 
(Refer to Figures 3-15 and 3-16). Adjust 
potentiometer R5 for a level of 5.0 VDC f 0.01 V. 9.02 External Paging . 
External paging is provided via the use of a station 
circuit. To install external paging proceed as follows: 
3. Reassemble the OSWBLF Run a jumper cable between a modular six- 
conductor connecting block and the circuit 
connector on the STN PCB. 
7.00 CPU iNiTiALiiTATiON ROUTINE 
To initially program ihe MPK System, perform the 
following procedure. (Refer to Figure 3-9 and Figure 
3-10.) 1. 
2. 
3. 
4. 
5. Short the receive pair on the modular connect- 
ing block and connect it to the +36 VDC screw 
terminal. (Refer to Figure 3-18.) 
1. Place all CPU PCB switches in the OPEN 
position. Using a 500 ohr? to 8 ohm audio transformer, 
connect the 500 ohm side to the transmit pair on 
the connecting block. 
2. Place function switch 4 (TEST) in the CLOSED 
position momentarily, and return it to the OPEN 
position. 
. . Connect the 8 ohm side of the transformer to the 
amplifier input. 
NOTE: If the CPU fails the test (i.e., the 4 LED’s on 
the CPU fail to light within 30 seconds after 
the test sequence begins, this indicates a 
defective CPU card. Contact INTER-TEL 
Field Service for assistance, To access external paging, dial the station 
number used as the amplifier input. 
10.00 OPTIONAL MUSIC-ON HOLD (MOH) 
MODULE 
10.01 installation 
3. Turn the MPK Power Supply OFF then ON. 
4. Momentarily place function switch 3 (INIT) in 
the CLOSED position, then return it to the 
OPEN position. This completes the MPK initial- 
ization sequence. To install the optional MOH module, proceed as 
follows: 
1. Remove the synthesized music IC frbm socket 
U31. (Refer to Figure 3-9.) 
8.00 OPTIONALSTATION MESSAGE DETAIL RE- 2. Remove the two screws and nuts which mount 
CORDING (SMDR) the W-232 connector to the CPU PCB. 
8.01 installation 3. Carefully insert the 1’6-pin connector of the 
MOH module into socket U31. 
Plug the standard INTER-TEL printer cord with the 
RS-232 connector directly into the receptacle on the 
front of the CPU PCB. (Refer to Figure 3-9 and 
Figure 3-l 7.) 4. Insert the two mounting screws through the 
back (solder side) of the CPU PCB and into the 
MOH PCB. 
9.00 PAGING CONNECTIONS 11.00 OPTIONAL BAT-JEdY BACK-UP 
9.01 internal Paging 11.01 General I 
The internal paging zones and the all page feature 
have been incorporated into the MPK system. (Refer 
to Figure 3-12 for internal paging zone assignments.) 
A. Any station may page any zone. The MPK system may be provided with battery back- 
up. Battery back-up supplies power automatically to 
the KSU if the main ACvoltagedrops below the KSU 
power supply regulator limit. Batteries used should 
be of the gell-cell type.

I 11.02 Installation of Battery Back-Up 
To install battery back-up, porceed as follows: 
CAUTION: Make sure that the 680.06powersupply 
is on before connecting battery back- 
up. Do not place batteries inside the 
KSU cabinet or a sealed container. Ad- 
equate ventilation must be maintained 
because batteries give off gas. 
1. Make sure that the (+) and (-) batterywires 
are connected to the power supply. 
2. Turn on the AC power to the KSU. 
3. Measure and adjust the float voltage to 
+27VDC f 0.1. 
NOTE: The f/oat voltage should be measured at the 
polarized connector located on the battery. 
Adjust this voltage with a DVM which has an 
accuracy of 0.07 VDC. 
Figure 3-19 is provided to determine the 
battery ampere/hour rating to be used per 
system configuration. 
4. Make sure the battery switch is off. 
5. Connect the polarized connector to the 24VDC 
battery pack. 
6. Make sure that the battery light is on. 
7. Turn the battery supply switch on. 
8. Wait approximately 2 hours for the battery 
pack to partially charge. 
9. Turn off the AC power to the KSU. 
10. Make sure that the battery light is on and that 
the system is operating. 
11. Turn on the AC power.
