Any error in the mounting angle will directly affect the Doppler accuracy. At 35° nominal, an
error of 1° is approximately a 1% error in speed measurement. Post installation calibration
should be done to remove errors due to bracket alignment tolerances and vehicle levelness.

The TGSS should be secured to the mounting plate with bolts in all 3 bolt holes using 6 mm
Hex Head bolts and locking washers.
The bolts should be tightened to 5.4-7.3 Nm (48-65 in lbs).
Appropriate length bolts are routed from the underside of the unit through the mounting
plate and tightened into the shock absorbers on the unit’s base. The bolts should engage the
threads in the shock absorbers to a maximum depth of 6.35 mm (¼”).
NOTICE
At completion of installation, the validation steps
outlined in ‘HY33-5005-IB/US Instructions TGSS
740’ should be followed.
