intended for some USB devices.
•  You cannot connect a computer to the USB input 
terminal of the unit.
•  Make sure all important data has been backed up to 
avoid losing the data.
•  Do not leave a USB device in the car, expose to 
direct sunlight, or high temperature to avoid 
deformation or cause damages to the device.
•  Some USB devices may not work immediately after 
attaching USB device or turn on the power.

PocketFlat head screws—M5 × 8 mm (3/8") *2
When installing the unit without using the sleeve
In a Toyota car for example, first remove the car radio and install the unit in its place.
Electrical connections 
  Make sure to disconnect the battery’s negative terminal.
•  Be sure to ground this unit to the car’s chassis again after installation.
Note:
It is recommended to connect to the speakers with maximum power of more than 50 W (both at the rear and at the front, with an impedance of 4 Ω to 8 Ω). If the 
maximum power is less than 50 W, change “AMP GAIN” setting to prevent the speakers from being damaged (see “Menu operations” on page 3).
