Proper Use
The MP3 car radio - recorder KH 2389 is designed
for private use to receive radio stations broadcasting
on FM / AM / LW frequencies and to play audio storage
media like CD, CD-R, CD-RW, USB stick, MP3 player,
SD and MMC. It is suitable to record MP3 or WMA
formats on SD or MMC (not included) of the played
broadcastings. The MP3 car radio recorder has a
removable control panel and an IR remote control
whose power is supplied exclusively with 1 x Lithium
battery, type CR2025, 3 V DC. The power for the MP3
car radio - recorder must be supplied exclusively by
connecting it to 12 V DC. The device is designed to
connect four loudspeakers with impedance of
4 - 8 Ohm / output max. 4 x 45 W, a fi nal amplifi er and
a CD changer. Any careless use or use that is not in
compliance with the intended purpose of the device
entails a loss of warranty.

the packaging material! Risk of suffocation!
• Do not allow infants and children unsupervised
into the vicinity of the device!
• Protect yourself against an electric shock!
Avoid any short circuits during connections:
- with the vehicle’s 12 V DC power supply
- with the max. 2 pairs of loudspeakers with
the impedance 4 - 8 Ohm
- with a CD changer
- with a terminal amplifi er
• Before connecting to the 12 V DC power supply
of a car, obtain information on how to maintain
electrical safety based on the vehicle‘s operation manual!
• Ensure that when connecting to a vehicle‘s 12 V
DC power supply, there is no voltage in the vehicle‘s connecting cables. Equip the connecting
cords with fuse holders (2 x 8 A)!
• When installing into a car, ensure that the vehicle
is out of operation and in a secure standstill
position! Turn off the ignition and bring the vehicle
into parking position with applied hand-brake.
