Jumper Options Notes
JP1 Recorder Output & VU meter The audio recorder output and the VU meter
include the console microphone transmit audio and
its Select receive audio. Place the jumper in
position B to add Unselect receive audio as well.

B Unselect audio mixed with Select audio to Recorder
Output and VU
JP2 Auxiliary Audio to Select Audio The transmitted audio from the auxiliary audio
input may be monitored with the Select speaker.

operator can hear the encoder tones as they are
being transmitted.

JP3 Unselect Speaker / Headset & Handset Audio Determines where Unselect audio is heard. You
might want to change this if, for example, you want
the Unselect speaker to turn off when the software
detects a handset lifted from a cradle or a headset
plugged into a jack.

B Unselect audio switch under software control
C Unselect audio always on headset/handset
JP4 Headset/Handset Unselect Monitor Occasionally, it is desirable to monitor both Select

or handset. Jumper JP4 may be used to enable the
Unselect audio monitoring.
A* Unselect audio not heard at headset/handset
B Unselect audio heard at headset/handset
JP5 Auxiliary Audio input impedance If an external encoder is used, use JP5 to set the
input impedance of the Model 4010 to match the
output impedance of the encoder.
A* Auxiliary Audio 600 Ω impedance
B Auxiliary Audio 10 kΩ impedance
JP6 Select Speaker / Headset & Handset audio Determines where Select audio is heard. You might
want to change this. For example if you want the
Select speaker to turn off when the software detects
a handset lifted from a cradle or a headset plugged
into a jack.

JP10 Operator Paging/Alert/Warning Audio Operator audio refers to the paging and alert/
warning tones generated by the M4010. These
tones can be irritating when monitored by the
dispatcher, depending on where it is heard and how
loud it is. The level is adjusted by R104.
