■ Remote control
Problem
The remote control does not work
nor function properly.
The remote control does not
“learn” new functions.
Cause
Wrong distance or angle.
Direct sunlight or lighting (from an inverter type of
fluorescent lamp, etc.) is striking the remote control
sensor of this unit.
The batteries are weak.

Even if the manufacturer code is correctly set, there
are some models that do not respond to the remote
control.
The batteries of this remote control and/or the other
remote control are too weak.
The distance between the two remote controls is too
much or too little.
The signal coding or modulation of the other remote
control is not compatible with this remote control.
Memory capacity is full.
Remedy
The remote control will function within a maximum
range of 6 m (20 feet) and no more than 30 degrees
off-axis from the front panel (see page 10).
Reposition this unit.
Replace all batteries with new ones and press RESET.
Set the manufacturer code correctly (see page 66).
