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.
15. Call Signal Jumper: In some installations it is important to receive a call 
signal from either channel, regardless of the setting of the channel selector. 
The plug-on jumper P1 makes the call light respond to either (a) the selected 
channel or to (b)either channel, depending upon its orientation. By default, 
the jumper is set to the selected channel position. When the TW or 4-Wire
