TROUBLESHOOTING

If there is no sound from either of the

speakers:

• Check that the unit is plugged into an active

electrical outlet.

• Check that the unit is turned on, and that a

source is selected and playing. If Tape or CD

was selected, make sure that a cassette or disc

has been inserted.

• Check that the Mute function has not been

selected and, if it has, turn it off using the

remote control.

• Adjust the Volume Control ⁄.

• Check all wires and connections between the

main unit and the speakers (see page 9). Make

sure all wires are connected, and that none of

the speaker wires are frayed, cut or punctured.

• If an external (auxiliary) source was selected,

make sure that the external unit is either

plugged into an active electrical outlet or pow-

ered by fully charged batteries. Make sure that

the external unit is turned on and playing.

Make sure that all wires between the main unit

and external unit are connected correctly, and

that none of the wires are frayed, cut or punc-

tured.

If there is no sound coming from one

speaker:

• Check all wires and connections between the

main unit and the speakers (see page 9). Make

sure all wires are connected and that none of

the speaker wires are frayed, cut or punctured.

If the system plays at low volumes but

shuts off as volume is increased:

• Check all wires and connections between the

main unit and the speakers (see page 9). Make

sure all wires are connected, and that none of

the speaker wires are frayed, cut or punctured.

If there is low (or no) bass output:

• Make sure the connections to the left and

right speaker inputs have the correct

polarity (+ and –).

• Consider experimenting with the Boost func-

tion ﬁ by selecting either PowerBass or Super

Boost.

• Consider adding a powered subwoofer to your

system.

If there is low (or no) treble output:

• Check all wires and connections between the

main unit and the speakers (see page 9). Make

sure all wires are connected, and that none of

the speaker wires are frayed, cut or punctured.

• For Model SG3030, make sure the yellow plug

is connected to the correct Tweeter/Midrange

jack on the rear panel of the main unit.

• Consider experimenting with the Boost func-

tion ﬁ by selecting Treble Boost or Super

Boost.

• As a preventive measure to avoid damaging

your speakers, make sure never to exceed the

maximum volume when playing your system.

If the unit does not respond to remote con-

trol commands:

• Make sure the batteries are not weak, and

replace them if necessary.

• Make sure the remote sensor in the front

panel of the main unit is not blocked.

• Make sure the remote is no further than 23

feet (7 meters) away from the main unit, and

that it is aimed at the sensor head-on and not at

too much of an angle (no more than 30 degrees

from the center line).

• Turn off any fluorescent light in the vicinity of

the JBL Soundgear main unit.

If the tuner (radio) buzzes or does not play

properly:

• Make sure you have tuned in to a frequency

that is in use in your area.

• Check the antenna connection, and adjust

the placement of the antenna wires for best

reception.

If RDS (Radio Data System) information

does not appear in the display:

• Make sure you have selected the FM band, as

RDS is not available on AM.

• Make sure the station you have tuned is

broadcasting an RDS signal by checking the

Web site listed on page 12.

• When the station’s signal is weak, the audio

signal may come through without the RDS

signal.

• For the first few seconds, the RDS data will

be garbled until the unit fully processes the

signal.

When attempting to delete a single preset

station, all presets are erased:

It is not possible to delete a single Preset sta-

tion, although it can be changed to a different

station (see page 12).

When attempting to delete a single track

from a programmed CD play list, the entire

play list was erased:

It is not possible to delete a single track from a

play list, although the track can be replaced by a

different track (see page 14).

If no sound is heard when tape is playing:

• Make sure tape is not blank.

If tape does not record:

• Make sure record protection tabs have not

been removed from cassette. If they have, you

may cover the protection holes with adhesive

tape.

• Make sure a source is playing.

• If dubbing, make sure the tapes are in the cor-

rect decks – the source in Deck A, and the blank

in Deck B.

• Make sure you are not attempting to record

onto a tape in Deck A, as that deck is for play-

back only.

If tapes sound distorted:

• Make sure to use only normal bias tapes in

the unit.

• Make sure tape heads are clean and demag-

netized.

If a tape recording tapes over material

recorded earlier in the same session:

• Make sure you have selected either One side

or All sides, but not Endless loop, using the

Play Mode function h.

If a tape rewinds past zero:

The unit detects the beginning of the tape

rather than the counter number and this behav-

ior is normal.

If Deck A does not auto-reverse:

Deck A is not equipped with this feature, and

will always stop at the end of each side.

If CD does not play:

• Make sure drawer contains disc to play.

• Make sure disc is not upside down in tray.

• Make sure disc is of type CD or CD-R only.

If CD skips or stutters during play:

• Make sure disc is not damaged.

• Make sure main unit is set securely on a sta-

ble surface, free from vibrations.

If the unit did not turn on at the pro-

grammed alarm time:

• Check programmed time – was AM or PM

selected correctly? Was 24-hour or 12-hour time

display selected as desired?

• Make sure the unit was not left turned on.

If the unit did not turn on and make a

recording at the programmed alarm time:

• Make sure time was programmed correctly.

• Make sure a blank tape was inserted in

Deck B and rewound.
