Rosen A10 Owner’s Manual
USING THE INCLUDED WIRELESS HEADPHONES
The system comes with two pair of wireless infrared (IR) single-
channel headphones (AC3003). These headphones receive a signal
from an IR transmitter built into the A10. These headphones allow
rear-seat passengers to listen without using the vehicle speakers.
To turn the headphones on and off, push the Power ON/OFF button
on the right ear piece. The Power LED on the left ear piece indicates
when headphone power is on. Power turns off automatically after
three minutes of no audio, in order to preserve battery life.
To adjust the headphone volume, rotate the thumb wheel on the
headphones.
To adjust the headphone size for differently-sized heads, slide the
top as needed (see below).

The A10 IR transmitter has two output channels, A and B. Using A and
B, the A10 can transmit two different audio programs at the same
time. When using optional Rosen AC3072 dual-channel headphones,
listeners can switch between Channels A and B. For more, see P. 22.
LISTENING OVER THE CAR SPEAKERS
The system uses an FM Modulator (FMM) to send audio through the
vehicle radio and speakers. To listen to the A10 over your speakers:
1 Make sure system MUTE is off. Press SPEAKER. “SPEAKER
SOUND ON FM _ _ . _” appears. (If “SPEAKER SOUND DIS-
ABLED” appears, select an FM frequency as described below.)
2 Turn on the car radio. Tune to the FM frequency displayed on the
screen, such as “FM 87.7”.
3 If no system audio is heard, try changing the FMM frequency and
re-tuning the radio to the new frequency.
To change the FM Modulator frequency:
Press SPEAKER. “Speaker Sound on FM _ _ . _” will be displayed.
Now use the Left and Right buttons to change the frequency. The
FMM frequencies are 87.7, 87.9, 88.1, 88.3, 88.5, 88.7, 88.9,
106.7, 106.9, 107.1, 107.3, 107.5, 107.7, and 107.9. After you
select a frequency, re-tune your radio and check for clear sound.
The system saves the frequency you select, and returns to it each
time the system is turned on. You may want to store the FM Modulator
frequency as a preset of your radio for ease of use.
Note: If there seems to be a strong station on the FM
Modulator frequency, and you are hearing a radio station
mixed in with the system audio, change the FM Modulator
frequency. Avoid frequencies used by local radio stations.
If the words “SPEAKER SOUND DISABLED appear, the Internal FMM is
turned off. It can be turned on by pressing the left or right arrow keys
and selecting an FM frequency. If the words “HEADPHONE SOUND
ONLY” appear, an external FM Modulator is probably being used. In
this case, the SPEAKER button turns the external FMM on and off.
The Rosen external FMM is uses either FM 87.9 or FM 88.3. If you
have any questions about your FMM, please ask your Rosen dealer.
