Note:
This feature is automatically turned off if the operating mode of the
KB-701 is set to any setting other than normal.
8.
Minimum Volume Control:
This control adjusts the minimum setting of
the
intercom level
control on the front panel. Setting this control can prevent
people from inadvertently turning the intercom level all the way down. This
is normally adjusted when the system is set up and shouldn’t need to be
adjusted during normal operation. This feature can be disabled by turning
the control fully counterclockwise.
9.
Option Switches:
Three
option
switches are provided. They should be
configured when the system is set up, but are not changed in normal
operation.
Note:
The “on” position of each switch is toward the circuit board and the
“off ” position is toward the front panel. A description of the function
of these switches follows.
•
Internal Microphone Gain (S-1)
— This switch determines the
microphone’s sensitivity. When the switch is in the
on
position, talking
should be done within 2 ft. (0.61 m) of the front panel. If it is necessary
to talk from a greater distance, the switch should be turned
off
. The
default position of this switch is in the
on
position.
•
Operating Mode (S-2 and S-3)
—These switches work together to
define the operating mode of the KB-701. In modes other than normal,
the call signal from other stations on the same channel activates the
KB-701. Refer to the following table:
Table 1: KB-701 Operating Mode Options
•
The default position of these switches is in the
off
position for normal
mode, which is the only mode in which the call alert tone functions
operate. In other modes, the call alert tone is automatically disabled to
avoid interference with operation.
Note:
Only normal mode may be used when the EB7-4W four-wire option
module is installed.
