System Configurations and Function Jumper Settings
!
Important
Whenever a jumper setting is changed, the RESET SWITCH on the base station circuit board must be pressed
to program the new jumper setting into the microprocessor. Also, each of the headsets in the system must be
reprogrammed when a jumper setting is changed (see Channel Selection on page 14 for the headset
programming procedure).
Determine the system type (standard operation – single lane, etc.) and identify the type of speaker (speaker only or
speaker and microphone) and the type of vehicle detector (air switch or loop/SODAR detector).
Refer to the base station circuit board illustration (Figure 14) and the applicable system configuration below. Set
the function jumpers as noted and per the type of speaker and vehicle detector in the system. (An illustration of the
circuit board also appears on the decal inside of the base station half–cover.)
