13—Call Alert Tone Level Control
This 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.
14—Option Switches
Three Option switches are provided. They should be configured when the
system is set up and shouldn’t be 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 default position of the switches is in the
OFF position. The function of each switch is as follows:
