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:
•

Module is installed.
Rev. B
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:
S1-2 S1-3

Table 1: KB-212 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.
