    Description

    This telephone line busy indicator displays a GREEN led lamp when the telephones in the line are not in use.  When any single telephone in the common line is in use the RED led will light up.  The system uses a 9-volt rechargeable LI-ion battery for reliable display regardless of the telephone line voltage.  The circuit includes a voltage regulated battery charger to maintain the battery charged.  It will charge the battery only when the telephone is not in use.  Battery is not included.  An adapter is included to connect the Indicator to the telephone line.
