humans, be sure that there is nobody within at least 5 feet of the vehicle’s
speakers when Si-Test™ is running.
Diagnostic Indicators
- The LED’s above the Air Horn and Momentary
Siren buttons act as diagnostic indicators for speakers #1 and #2
respectively (if the vehicle is equipped with a second speaker). When a
speaker is active, or in use, it’s indicator will be on. If a problem is detected
with a speaker, it’s indicator will flash, thus alerting the operator to the
failed speaker’s condition. If enabled by the factory or a factory authorized
representative, a series of 3 separate alarm tones will be heard whenever
a failure has been detected.
SW4 thru SW8
- These push-button switches activate specific, pre-
programmed functions of the network. These 5 buttons are referred to as
switches 4 (furthest button to the left) through 9. Refer to the Slide Switch
section for information on the first 3 controls. If you are not sure exactly
how each control is configured, the configuration report, included with the
MPC03, details the customized functions for each control. Although each
control is custom configured, control 8 can be programmed to handle
specific functions of the network:
SW8
is typically designated to control Traffic Advisor functions, if the
vehicle is equipped with a Traffic Advisor. There are 4 patterns that are
pre-programmed by the factory. Although specific patterns can be
configured at the customer’s request, the basic, non-custom patterns are
described here for example purposes:
Press Control 8 ....................................... Sequence to Left
Press Control 8 a second time................ Sequence to Right
Press Control 8 a third time .................... Split Pattern
Press Control 8 a fourth time .................. Flashing Pattern
To terminate Traffic Advisor operation, press and hold Control 8.
SLIDE SWITCH
- The slide switch has 4 positions:
Position #0
(farthest to the left) - This is an OFF position. When the slide
switch is in this position, none of the programmed functions of the
remaining 3 positions are active.
Position #1
(one detent to the right of the OFF position) - When the slide
switch is in this position, the programmed function for this position is
active. To de-activate position #1 functions, move the slide switch all the
way to the left (Position #0).
Position #2
(two detents to the right of the OFF position) - When the slide
switch is in this position, the programmed function for this position is
active. To de-activate position #2 functions, move the slide switch all the
way to the left (Position #0).
Position #3
(three detents to the right of the OFF position) - When the
slide switch is in this position, the programmed function for this position is
active. To de-activate position #3 functions, move the slide switch all the
way to the left (Position #0).

Wire Gauge (AWG)
Determine the amount of current being drawn through
the wire. Locate this number in the vertical left-hand
column. If the current value is between adjacent values,
use the higher number.
In the example shown below, the size for a wire with an
installed length of 36 feet, through which 22 amps of
current will be drawn, must be determined.
Follow this row until the length of the installed wire is
shown. If the exact length is between adjacent values,
use the higher number. Follow this column upwards to
find the recommended size (gauge) for this wire.
A row for 22 amps is not shown, so the row for 25 amps
will be used. Follow this row to the right. A column for 36
feet is not show, so the column for 49.5 feet will be used.
Following this column to the top will show that the size
of this wire must be at least 6 gauge.
