Troubleshooting

After inserting the batteries in the remote control,
the display does not illuminate:
• The batteries are exhausted or the polarity is incorrect;
replace the batteries or check polarity.
When pressing the recessed clock adjustment
button, the hour figures on the display do not flash:
• The recessed button has not been pressed correctly;
keep it pressed for at least 5 seconds.
When pressing any button all symbols appear on
the display:

after having removed the obstacles.
• The receiver on the unit or the remote control is
exposed to intense sun radiation; avoid direct sunlight
on the unit, draw curtains or shut shades, or move the
remote control.
• Signal transmission is obstructed by severe electroma-
gnetic field interference; avoid sending signals when
computers or household appliances (food processors,
coffee makers, etc.) are operating close by. Cellular
or cordless telephones may also interfere with the
control.
When pressing the stop button the unit does not

the cool air coming into contact with the room air.
A slight whistling noise is heard when the air
conditioner starts or stops:
• This is due to the refrigerant beginning to circulate or
an adjustment of the refrigerant pressures. This is a
normal operating condition.
