AT&T SynJ Music On Hold Quick Programming Guide

UNDERSTANDING NECESSARY CONNECTIONS It is highly recommended to use the audio cable that comes with the AT&T phone. That cable has two different-sized ends. One is a 3.5-millimeter (mono) plug, and the other is a 2.5-millimeter (mono) plug at a 90-degree angle.

The smaller end of the cable, the 2.5-millimeter plug, fits directly into the headset/aux receptacle on the Syn-J phone. Never use any plug other than the 2.5-millimeter plug in the headset/aux receptacle.


The 3.5mm plug requires an adapter for use with the music-on-hold player. The adapter needed can be provided by Easy On Hold® or purchased on Amazon. This adapter accepts the connection and converts it to RCA type. For best results with the Easy On Hold audio device, plug the 3.5-millimeter end of the cable that came with the AT&T SB67158 phone into the adapter. Then, the adapter fits into and over the receptacle on the music-on-hold player. (Never insert a 3.5-millimeter plug into an RCA fitting without first converting it to an RCA-type plug, as this can cause damage to the player.)
