6-3. JOYSTICK CONTROLS.
If you experience problems operating any controls, turn off your SINGAR radio unit. Failure to
comply may result in death or injury to personnel and/or damage to equipment.
Electronic controls, devices, and systems may be
susceptible to electromagnetic interference (EMI) if
inadequately shielded or otherwise configured for
electromagnetic compatibility. When operating any of
the vehicle's controls while the SINGAR radio is on,
EMI could occur. If you notice controls not responding
correctly, or at all, turn your SINGAR radio off.
The FEL assembly is operated by hydraulic pressure
supplied by the vehicle's hydraulic system. The driver
controls the functions of the FEL using joystick controls
incorporated into the armrests of the driver's seat.
