PROTECT YOUR FURNITURE!!

This system is equipped with non-skid rubber ‘feet’ to prevent the product from moving when you
operate the controls. These ‘feet’ are made from non-migrating rubber material specially formulated
to avoid leaving any marks or stains on your furniture. However certain types of oil based furniture
polishes, wood preservatives, or cleaning sprays may cause the rubber ‘feet’ to soften, and leave
marks or a rubber residue on the furniture.
To prevent any damage to your furniture we strongly recommend that you purchase small self­adhesive felt pads, available at hardware stores and home improvement centers everywhere, and
apply these pads to the bottom of the rubber ‘feet’ before you place the product on fine wooden
furniture.

POWER SOURCE

This Unit is designed to only operate on normal 120V~ 60Hz household power. Do not
attempt to operate the System using any other power source. You could cause damage to
the unit and void your warranty.
The remote control unit operates on 1 CR2025 Lithium battery (Included).

2. Turn the System on by sliding the Function Selector (12) to either “TUNER”, “USB/SD”

or “PHONO”. The LCD backlight will turn on.

Remarks:

If there is a malfunction due to electrostatic discharge (ESD), reset the unit by unplugging
the AC CORD from the outlet, wait 30 seconds and then plug the AC CORD in again to
reset to normal operation.

ACTIVATING THE REMOTE CONTROL

BATTERY CARE
i. If the unit is not to be used for an extended period of time, remove the battery. An old or

leaking battery can cause damage to the Remote Control.

ii. Do not dispose of batteries in fire, batteries may explode or leak.

BATTERY REPLACEMENT

When the battery becomes weak, the operating distance of the
Remote Control is greatly reduced and you will need to replace the
Lithium battery.

1. Remove the battery compartment from bottom of the Remote
Control.

2. Install 1 “CR2025” Lithium battery with the positive side facing up.

3. Replace the battery compartment.

IMPORTANT

: Be sure that the battery is installed correctly. Wrong polarity may damage the

Remote Control and void the warranty.

USING THE REMOTE CONTROL CORRECTLY

Note: The Remote Control is only for operating the USB and MMC Card functions.

z Point the Remote Control at the SENSOR (IR) located on the front of the System.
z The functions of the remote buttons are the same as the corresponding controls on the

main unit.

z The performance of the infrared SENSOR may be degraded causing unreliable

operation if there is a strong ambient light source in the same room.

z The recommended effective distance for remote operation is about 10-15 feet.

RADIO OPERATION

1. Slide the FUNCTION Selector (12) to the “TUNER” position.

2. Slide the BAND Selector (11) to either AM, FM or FM ST (FM Stereo Mode).

3. Rotate the TUNING CONTROL (10) until you reach the radio station you wish to listen

to. The radio station frequency shows on the LCD DISPLAY.

4. Adjust the sound level by rotating the VOLUME CONTROL (23).

5. To turn off the radio, Slide the FUNCTION Selector (12) to the “OFF” position. The

LCD DISPLAY will go “off”.

FM STEREO RECEPTION

With the BAND Selector (11) in the “FM ST” position, the FM Stereo Indicator “

” will
light up when listening to a strong station that is broadcasting in “Stereo”.
Slide the BAND Selector (11) to the FM position if the FM stereo reception is weak. The
reception may improve, but the sound is now monaural (MONO).

TIPS FOR BEST RECEPTION

AM – The AM antenna is located inside the cabinet of the main unit. If AM reception is

weak, change the position of cabinet until the internal antenna picks up the
strongest AM signal.

FM – During FM reception, always keep the FM Wire Antenna fully extended. If FM

reception is weak try repositioning the FM Wire Antenna until you find the strongest
FM signal.
