the unit. Never touch them.

The mounting tabs rise as the screws turn, allowing the

speaker to be removed.

Notes

• When loosening the mounting tab axis screws,

support the IR-820SP by hand to prevent it from

falling.

• Be sure to set the screwdriver's torque for under

0.58 N·m (6 kgf·cm.)

Failure to do so may cause the screw cap and the

mounting tab to fall off on the rear of ceiling panel.
