Moisture condensation
On a rainy day or in a very damp area, moisture
condensation may occur inside the lenses and
display of the unit. Should this occur, the unit
will not operate properly. In such a case, remove
the disc and wait for about an hour until the
moisture has evaporated.
To maintain high sound quality
Be careful not to splash juice or other soft drinks
onto the unit or discs.
To prevent the wireless rotary
commander RM-X5S from falling off
(supplied with CDX-M770 only)
If the wireless commander falls off, it could
cause an accident.
•Be sure to attach the supplied strap when
installing the rotary commander near the
steering wheel.
•Be sure that the strap does not get caught on the
car controls (gear, shifter, etc.).
•Be sure to tighten the stopper of the strap after
hanging the strap on the indicator switch, etc.
