UNIT 3: INSTALLATION - LESSSON 5: OPTIONAL ACCESSORIES

Background Music and Music On Hold Connections

The last part of the installation process is the connection of other optional peripherals such as Music on Hold source, Paging system, Doorphones and Door Openers, and a serial device to the RS-232C connector. Not all of these devices will be necessary in a typical installation but may need to be installed based on the needs of the customers.

The KX-TAW848 includes both Background Music (BGM) and Music on Hold (MOH) capabilities. The Background Music feature allows proprietary telephone users to listen to music through the telephones speaker while the phone is idle. When the extension becomes busy the music stops temporarily and begins again when the extension becomes idle. Three options are available for the background music audio source. By default, the internal background music melody 1 is used as the background music source. System programming can be used to change the source to internal background music melody 2 or to use an external music source.

The Music on Hold feature provides an audio source to callers who are placed on hold on the system. By default, the audio source used for background music is also used for Music on Hold. System programming allows an intermittent tone, instead of music, to be heard by the callers placed on hold.

If an external music source is going to be used, anything from an inexpensive radio with an audio output jack, to a CD player or tuner can be used. Other devices such as digital announcers can be used to broadcast audio messages or advertisements to those callers placed on hold.

Included with each Main Unit are two 3.5-mm mono mini-plugs. One plug will be used for the music on hold source, the other for paging. The type of audio source you select will determine the type of jack and cable that will be needed on the music source side. The 3.5-mm plug must be attached to the other end of the cable by soldering the two wires within the cable to the mini-plugs terminals. Once soldered, the mini-plug can be inserted into the jack on the Main Unit labeled MOH.

To test the audio source and set the volume level, turn the Main Unit ON. From any telephone, call another telephone on the system, answer it and then press the hold button. Audio should be heard at the first telephone. Listen to the audio source's volume level and ensure that it is at a comfortable listening level. Adjust the audio source as needed.
