SB-704 MAIN STATION

1-7

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.
