JENSEN Wireless Speakers eliminate the hardest part of adding
speakers to almost any location in your home — running and hiding
hundreds of feet of speaker wire. Like FM radio, the JENSEN Wireless
Speaker System’s 900MHz signals travel through walls, floors, ceilings
and other obstacles, delivering high-quality sound virtually anywhere
in or about the home,
The JENSEN Wireless JW250 stereo speakers are designed to provide
high»quality sound in challenging locations, such as a home office,
dining room, or outdoor patio. The mounting holes on the back of the
speakers allow them to be easily mounted on a wall to provide hours
of music enjoyment.
The JENSEN Wireless JW250 Speaker System is compatible with most
audio sources, i.e. TVs, VCRs, stereo receivers/amps, personal stereos,
boom boxes, DSS receivers, and individual stereo component pieces
(DVD/CD players, cassette players, etc.) The contents of this manual
cover various connection options and detailed operating procedures for
making the JENSEN Wireless JW250 Speaker System a valuable part of
your daily routine. If, after having reviewed the instructions you have
any questions, please contact our Customer Service Department at 1-
800-732-6866.

CONNECT THE TRANSMHTER
Connect the transmitter as follows:
Step 1 Power the Transmitter
1. Insert power cord from 12V AC Adapter (L) into the transmitter
Power Input Jack (G). Note: Be sure to use the 12V DC
100mA Adapter.
2. Plug AC Adapter (L) into any standard wall outlet or surge
protector.
Note: There is no transmitter ON/OFF switch. The transmitter should
be left plugged in and powered at all times. When the JW250 is not in
use for an extended period of time you may wish to unplug the AC
Adapter.

ADJUST THE TRANSMITTER
Adjust the transmitter as follows:
STEP 1 Turn ON your Audio Source (i.e. Stereo Receiver, TV, PC,
etc.) so that you can hear sound coming from the source.
STEP 2 Pivot the Transmitter’s Antenna (K) to an upright, vertical
position.
STEP 3 Set Transmitter Level.
1. Set the Channel Select Switch (J) to either channel A or B.
2. Turn the Input Level Control (H) all the way to the left (your left
when looking at the transmitter controls), as shown.
3. Check status of Audio Level Indicator (F). If Audio Level
Indicator (A) flickers intermittently, proceed to CONNECT THE
SPEAKER.
4. If the light does not flicker or is solid red adjust the PC's Volume
Control up or down as necessary to make the Audio Level
Indicator flicker intermittently.
CONEEQ! THE SPEAKER
Connect the speaker as follows:
Sten 1 Pgwer the Speaker
Select from the following options to power the JW250:
Power Option 1 — “C" Cell Batteries
1. Turn the speaker Power On-OffNolume Control (C) to the “OFF”
position (all the way counter-clockwise - it will “click” off).
2. Remove the Battery Compartment Cover (E).
3. Insert four (4) “C" batteries (not included) into the speaker
following the polarity (“+” and “—“) as diagrammed in the battery
compartment.
4. Replace the Battery Compartment Cover.
Power Option 2 — AC Adapter
1. Turn the speaker Power On-Off/Volume Control (C) to the “OFF"
position (all the way counter—clockwise — it will “click" off).
2. Insert the power cord from the Speaker AC Adapter (M) into the
Speaker Power Input Jack (D).
3. Plug AC Adapter (N) into any standard wall outlet or surge
protector.
Note: Be sure to use the AC Adapter rated 6V DC 200mA.
Step 2 Tgng the Sneaker
Adjust the speakers as follows:
Turn On and Tune the Speakers
1. Use the speaker Power On—Off/Volume Control (C) to turn the
speaker “ON.”
2. Turning the Tuning Control Knob (B) until the Tuning Indicator
Light (A) illuminates green, indicating that the speaker is tuned
to the signal from the transmitter. With the volume up, you
should now be able to hear the audio source.
3. Adjust Volume (C) as desired.
Note: If the Tuning Indicator flashes, try fine—tuning. If the light still
flashes, check the transmitter settings to make sure the signal is
strong enough, as indicated by the steady flashing Audio Level
Indicator on the transmitter. As needed, adjust the transmitter.
MORE FINE-TUNING
If, after fine-tuning, interference in the form of static and/or “drop-
outs” can be heard, adjust Channel Select Switch (J) to the other
channel and re-tune the receiver. If you are unable to achieve clear
sound, please refer to “Troubleshooting."
MORE HELPFUL INFORMATIQN
ABOUT FIXED-LEVEL OUTPUTS
A fixed-level, or line-level audio output is considered ideal since it
provides an audio signal unchanged by adjustments to the audio
source's (stereo, etc) volume control.
Hint: Fixed-level audio outputs from stereo receivers/amps will
typically be designated as Tape, Tape 1, and Tape 2 outputs, DAT
(digital audio tape) outputs, VCR audio output connections, and
auxiliary audio outputs. Tape, Tape 1, Tape 2 and DAT outputs are
usually marked as ‘TAPE OUTPUT,’ TAPE OUT,’ TAPE REC,’ or ‘TAPE
RECORD.’ Jacks
Many PC soundcards have a “Line Out” that is a fixed-level output.
Depending on the fixed output level of the soundcard, this signal may
not be strong enough for your optimal signal strength.
ABOUT VARIABLE-LEVEL OUTPUTS
A variable—level output is an audio signal that changes in relation to
the volume adjustments on the PC. The speaker output on a
soundcard is a variable-level output.
As the volume of the PC goes up and down, so too does the strength
of the audio signal sent to the transmitter. This can affect the quality
of the sound you hear on the home stereo, and may require increasing
the volume level of the audio source to achieve \a strong enough audio
signal for use with the Matrix, or decreasing the audio source volume if
sound from the headset is distorted by a too—strong signal.
TROUBLE SHOOTING
The following troubleshooting guide outlines possible problems and
corrections associated with the installation/operation of a wireless
system.’ If problems persist, please call 1—800—732—6866 and a
knowledgeable consumer service representative will assist you.
TROUBLE CHECKS AND ADJUSTMENTS '
No Sound
- Check that the outlets the transmitter and receiver are plugged
into are providing power.
- Check that the AC Adapters are fully inserted into the wall
outlets and the power cords from the AC adapters are firmly
connected to the Power Input Jack on the transmitter and
receiver.
- Check that the PC is turned on and providing sound as it
normally would.
. Check that the home stereo volume is turned up.
. If you are using the speaker output on your sound card, adjust
the volume on the PC up as necessary until the Audio Level
Indicator flashes (about half the time) and sound is heard
through the home stereo when the receiver is tuned.
No Sound/Distortion/Static
. Check that the receiver Tuning Indicator is lit. If not, adjust the
Tuning Control until the green indicator light comes on.
. Check that the antenna is in the upright position.
. Check that the transmitter Audio Level Indicator is flickering
intermittently. If using a fixed output and the light is on
solid/flickering very rapidly, or if the light is not on at all, adjust
the PC's volume control so the light flickers intermittently.
. Change the position of the transmitter’s Channel Select Switch to
change operating frequency. Then readjust the receiver’s Tuning
Control until the Tuning Indicator comes on.
- Try changing physical location of the transmitter. Locate as high
and free of obstruction as possible. Avoid placing directly on top
of a PC (or other electronic equipment), if possible.
- Try changing antenna position, particularly if you think you may
be near maximum transmitting range.
- Try moving transmitter and receiver closer together. Sending
the signal through certain materials, such as glass, tile, and
metal can decrease the effective transmitting distance of the
system.
Sound From One Speaker Only
0 Check left/right balance control on your PC’s volume control.
. Try fine-tuning the receiver at different transmitter Frequency
Control settings.
