Eel Slstem_LMultifunction (Hybrid) 
--- -I--__ Configuration 
The system can be configured to operate as either a key system or as a 
multifunction (hybrid) system. 
Configuration is by way of a wire strap placed between clip terminals 
27 and 28 of station connector block J-4. 
The KSU is shipped from the factory as a key system (KF). 
To convert 
operation over to the multifunction (MF) system, add the strap. 
The KF and MF designations are equipment type catagories as stipulated 
in FCC rules and regulations, Part 68, 
and appear as part of the FCC 
Registration Number on the equipment label. 
The appropriate 
registration number must be reported to the telephone company at the 
time of connection alonq with other FCC mandated information. (Refer 
to Installer/User Information Regarding FCC Rules and Regulations 
-.-_-.- -.-_ --- - 
foun~-mChap~Ser-l-ofthismanual.) 
Operationally, 
the multifunction (hybrid) configuration enables a PBX 
feature which may incur a higher monthly tariff to the telephone 
company. This feature allows dial access to (automatic selection of) 
outgoing lines. The specific Executech feature that is enabled by the 
multifunction (hybrid) configuration is: 
0 Line Group (Including Dial Access) 
Music Interface 
-- ---e-m- 
If music is to be part of the system, 
connect a KX registered music 
source to the KSU input jack (phono jack) provided for this purpose. 
The impedance of this input is approximately 500 ohms. 
Level 
adjustment of the music source may be necessary. This may be done 
during system checkout. 
Cassette Talc Recorder Interface 
__---.- - 
A customer provided, audio cassette, 
tape recorder can be connected to
