NOTE: Please heed the following safety warnings and precautions:
To prevent personal injury or vehicle damage please read safety precautions and warnings
before working on vehicle.
1.) Always perform automotive testing in a safe environment.
2.) Wear eye protection that meets ANSI standards.
3.) Keep clothing, hair, hands, tools, test equipment, etc., away from all moving or hot
engine parts.
4.) Operate vehicle in a well-ventilated work area. Exhaust gases are toxic.
5.) Use blocks on drive wheels and never leave vehicle unattended while running tests.
6.) Use extreme caution when working on the ignition coil, distributor cap, ignition wires
and spark plugs. These components create hazardous voltages when the engine
is running.

OVERVIEW
The STEELMAN PRO™Wireless ChassisEAR2®is a versatile noise, vibration, and harshness
(NVH) diagnostic tool. The STEELMAN PRO™Wireless ChassisEAR2®Digital Control Unit
receives NVH sounds from up to six transmitters that are connected to precision piezo
microphones embedded inside of the included sensor clamps. These clamps can be
attached to almost any location on a vehicle that is experiencing elusive NVH to amplify
sounds and aid in locating NVH. The unit can be used on a vehicle either while parked or
during a road test.
Some examples of areas where NVH originates and this unit can be used are:
• Wheel Bearings
• Brake Calipers
• C.V. Joints
• Leaf and Coil Springs
• Differentials
• Transmissions
• Body Mount Points
• Interior Trim
Please read carefully the following instructions to ensure optimum use of the product.
• Fuel Injectors
• Alternators
• Water Pumps
• Power Steering Pumps
• AC Compressors
• Accessory Pulleys
• Motor Mounts
• Engine Bay

CHARGING
DIAGNOSTIC USE
1.) To charge the Control Unit, use the included micro USB/USB cable. Plug the small end
into the micro USB port on the left side of the Control Unit. Plug the large end into a USB/
DC converter (not included) or into a USB charging receptacle. An LED on the power
button will illuminate RED while the Control Unit is charging. The LED will illuminate
GREEN when charging is complete.
2.) To charge the Transmitters, plug the Charging Station into an AC power source. Insert
each transmitter into an available slot on the Charging Station. The Transmitter status
LED will illuminate RED while the unit is charging. When charging is complete, the LED
will illuminate GREEN and then slowly fade to OFF.
It is illegal in many jurisdictions to operate a motor vehicle while wearing
headphones. It is strongly recommended that any road testing be conducted with a
dedicated driver AND a technician.
1.) Power on the Control Unit by pressing the power button once.
2.) Power on each Transmitter by plugging them into the Sensor Clamp. The status LED
will illuminate BLUE indicating that the Transmitter is powered and active.
3.) Place the Transmitters in each location that you wish to examine for NVH.
4.) In conned spaces, the Transmitter Jumper can be used to locate the clamp and
Transmitter separately. Plug the male end of the jumper into the Sensor Clamp. Plug
the Transmitter into the female end of the jumper.
5.) Secure Transmitters using included Velcro and nylon ties to ensure they are not lost
during road testing.

MAIN SCREEN
The Main Screen is the landing screen when Wireless ChassisEAR2®is powered on.
The use and functions of the main screen are described below:
1.) To select a channel to listen to, tap on the desired channel number
button. If the bar on top of the channel number button is green, the channel is active
and the transmitted sounds are being played back. If the bar on top is red, the channel
is inactive. The location label below the button can be set from the “Location Settings”
screen. The vertical color boxes on the right side of the channel button correspond with
the boot color on the Transmitters.
2.) The volume buttons control volume output from the control unit. Tap “-”
to decrease the volume and “+” to increase the volume. The sound from each Transmitter
can be played back through the integrated rear speaker or through the included
Headphones by plugging the headphones into the headphone port on the right side of
the control unit.
3.) The NVH Level Meter shows the signal (noise) level of the
selected channel being transmitted to the Wireless ChassisEAR2® receiver. The color
of the meter will change between green, yellow, and red based on the level of the noise
received with green being the lowest level and red being the highest.
4.) The Batt Meter shows the current Control Unit battery level. The meter will
change to YELLOW when charging is needed soon and RED when battery depletion is
imminent. The continuous run-time of the control unit is approximately 3.5 hours.
5.) The hamburger menu button will open the “Location Settings” screen where
the location for each Transmitter can be input. Additional settings and functions can be
accessed from this screen.

LOCATION SETTINGS SCREEN
1.) To edit Transmitter location information, tap the location text box
under the channel location you wish to edit. A digital keyboard will be displayed, allowing
the user to type the Transmitter’s location. Press “ENTER” to return to the Location
Settings screen.
2.) The “Clear” button clears any locations previously entered and
automatically returns to the Main Screen.
3.) The “X” button saves all changes and returns to the Main Screen.
4.) The “System Settings” button displays the System Settings screen.

System Settings Screen
Main Screen with Measurements ON
1.) The “Signal Sampling Rate” box allows the user to select the speed at which the
Wireless ChassisEAR2®samples the signal strength. Default is “Fast”. A slower rate will
slow the speed at which the signal strength bar graph moves in real time.
2.) The “Measurement Type” box allows the user to display the Peak Signal Strength
measurement or Average Signal strength next to each channel on the Main Screen. The
peak signal strength setting will capture and hold the highest signal level from each
channel while it is active. Average signal strength will capture the average signal level
from each channel while it is active and then hold that value when another channel
is selected. The default setting is “Measurement Off”.
3.) “The Default Settings” button restores all settings to their default values and returns to
the Main Screen.
4.) The “X” button saves all changes and returns to the Main Screen.
5. The Peak or AVG measurement appears next to every channel, when selected on the
setting screen.
6. The Clear button resets all measurements to 0% to begin the test again.

TRANSMITTER CHANNEL ADJUSTMENT
Wireless ChassisEAR2®has six dedicated frequencies for receiving NVH noises that
correspond to a dedicated channel on the receiver. Four pre-set Transmitters are included
and up to 2 more channels can be added. The Transmitter channel can be adjusted using
the dipswitches, located behind the TPR plug on each Transmitter unit. When adding
additional Transmitters or replacing old ones, the channel will need to be set before rst use
Please see the diagram below for the dipswitch setting for each channel.
