Warning when installing in a car without 
an ACC (accessory) position on the 
ignition switch
After turning off the ignition, be sure to press 
the power on/off button on the unit (or (OFF) 
on the card remote commander or the rotary 
commander) for 2 seconds to turn off the 
clock display.
Otherwise, the clock display does not turn off and 
this causes battery drain.
To turn the unit on, press the power on/off button 
(1) on the unit.
Note
If the unit is turned off by pressing the power on/
off button on the unit (or (OFF) on the card 
remote commander or the rotary commander) for 
2 seconds, it cannot be operated with the card 
remote commander or the rotary commander 
unless the power on/off button on the unit is 
pressed, or a cassette is inserted to activate the 
unit first.
