button on the station will send the microphone to all channels in the party-line
position.
Remote Mic Kill Function
When you press the remote mic kill pushbutton, the talk function shuts off for
every beltpack on all four channels. If the talk functions of a large number of
beltpacks have inadvertently been left activated, incidental noise and talking
can make it difficult or impossible to communicate on the party line intercom.
The remote mic kill button can be pressed to quiet the line in this situation.
Those needing to communicate can then set their talk functions to on as
needed.
Note: The remote mic kill button only functions if the SB-704 main
station is powering all of the stations in the system. Pressing the
button momentarily interrupts power to the other beltpacks and
stations in the system. If there are other power supplies or main
stations in the system, then the remote mic kill switch cannot
interrupt power and therefore cannot work.
HIDDEN FRONT PANEL OPTIONS AND
ADJUSTMENTS
This section describes the option DIP switches and various adjustment
controls behind the access panel on the front panel. These option switches and
controls are usually set and not used in daily operation of the unit.
To gain access to these controls, pull on the two latches on either end of the
access panel and remove it.
DIP Switch Options
The unit is shipped with all DIP switches, except the Headset Audio Limiter
switch, in their default positions (up). The Headset Audio Limiter switch is
shipped in the down (on) position.
The following functions are enabled with DIP switches:
• HEADSET AUDIO LIMITER: The HS dip switch turns the headset
audio limiter on or off. Unless an especially high volume is needed, this
switch should be left in the on position to protect the hearing of the user.
• INTERRUPT ENABLE: Three DIP switches enable the program
interrupt function on channels B, C, and D. Program interrupt is not
available on channel A.
• AUTO-CALL: Four DIP switches (one for each channel) enable
automatically sending a call signal whenever a talk is active on the
enabled channel.
• AUTO-TALK/LISTEN: Four DIP switches (one for each channel)
enable automatically setting the listen function whenever a talk is active
on the enabled channel.
