5. Enable the party line by pressing the CH A enable button on the
basestation’s front panel until the CH A enable light illuminates (see
Figure 2-2). Auto-nulling should be performed after the party line
circuit is connected. Pressing and holding the enable button for
eight seconds activates the auto-nulling.
Note: Be aware that a loud tone is generated in the party-line
beltpack’s headset during auto-nulling. This tone enables
the basestation to perform auto-nulling of the party line.
