HYBRID KEY SYSTEM
6. Connecting Optional Equipment
6.1 External Music Source
The system is equipped with an internal melody IC chip to provide Music On Hold (MOH)
through the keyset. However, when this is not desired, an external music source such as a
radio or tape recorder can be connected to the system.
The external music source can be connected to the EXT.MUSIC jack on the KSU using a
modular jack (Figure 2-19). After connecting the External Music Source, set the Music Source
selection shunt pin to EXT (Figure 2-21).
