KB-212 Speaker Station Clear-Com Intercom Systems

Rev. B

11—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. The function of these switches is as follows:

• Internal Microphone Gain (S1-1)— This switch determines the

microphone’s sensitivity. When the switch is in the ON position, talking

should be done within 2 ft. 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 (S1-2 and S1-3)—These switches work together to

define the operating mode of the KB-212. In modes other than Normal,

the call signal from other stations on the same channel activates the

KB-212. Refer to the following table:

• 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 EB-4W 4-Wire Option

Module is installed.
