System Interconnect
Refer to the interconnection diagram that is appropriate to the type of system you are installing.
Reminder about balanced and unbalanced systems: If interconnecting to an unbalanced system, be sure to
move the Intercom's internal jumper (P5/J5) to the U
position. For example, GAI-Tronics RigCom
NBAL
products use an unbalanced system; therefore, the Intercom's internal jumper (P5/J5) must be moved to
the U
position.
