then be accessible as shown in the lower view of Figure 1-3. The numbers in

Figure 1-3: Internal Adjustments and Connections
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 there should be no need to adjust it in 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, 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 default position of the
switches is in the off position. The function of each switch is as follows:
1. SINGLE CHANNEL: In some installations, the KB-702 is intended
to be used only with one intercom channel. Setting the single channel
switch to the on position will connect the KB-702 to the one intercom
channel regardless of the position of the front panel channel selector.
In two-channel installations, this switch must be set to the off
position.
2. LONG LINE: If a long cable run is unavoidable and approaches
700 ft. (213.5 m) or more, set the long line option switch to the on
position. The ability to set a sidetone null depends upon properly
setting this switch.
3. LATCH DISABLE: Setting the latch disable switch to the on position
will disable the latching function of the talk button. In this mode, the
talk button must be continuously pressed while the operator is talking.
