7. Call Alert Tone Level Control: This internal control adjusts the volume
of the call alert tone sound. 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.
An audible tone alert can sound when a call signal is received on the
intercom channel. This can be useful when the operator's attention has
been drawn away from the KB-701 indicator panel. The tone alert will not
sound if a call signal is originated at the KB-701 station.
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:
