DEAR JENSEN ® CUSTOMER
Selecting fine audio equipment such as the unit you've just purchased is
only the start of your musical enjoyment. Now it's time to consider how you
can maximize the fun and excitement your equipment offers. This
manufacturer and the Electronic Industries Association's Consumer
Electronics Group want you to get the most out of your equipment by playing
it at a safe level. One that lets the sound come through loud and clear
without annoying blaring or distortion and, most importantly, without affecting
your sensitive hearing.
Sound can be deceiving. Over time your hearing "comfort level" adapts to
higher volumes of sound. So what sounds "normal" can actually be loud
and harmful to your hearing. Guard against this by setting your equipment
at a safe level BEFORE your hearing adapts.
To establish a safe level:
Start your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and
clearly,and without distortion.
Once you have established a comfortable sound level:
Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or loss
in the future. After all, we want you listening for a lifetime.
We Want You Listening For a Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and
enjoyment. Since hearing damage from loud noise is often undetectable
until it is too late, this manufacturer and the Electronic IndustriesAssociation's
Consumer Electronics Group recommend you avoid prolonged exposure
to excessive noise.

This unit is designed to operate on 120V/60HzAC house current. Operating
this unit from any other power source may cause damage to the unit, and
such damage is not covered by your warranty.
The radio is also pre-loaded with 2 x “AA” batteries for the battery back-up
and for the Auto Time Set clock system.
BATTERY BACK – UP SYSTEM
The Battery Back-up System ensures the clock and alarm settings will be
retained during a power interruption or power outage (in order to preserve
the battery life the Display will not light). All clock settings will be kept in
memory, however, the clock time may require adjustment for exact accuracy
once the power returns. If the batteries are not installed, the Display will
blink”12:00” when the power is restored. This will indicate that you have to
reset the time and alarm settings.

to the polarity diagram engraved inside the compartment.
3. Replace the battery compartment Door.
IMPORTANT:Be sure that the batteries are installed correctly. Wrong
polarity may damage the unit.

these batteries should be replaced after every year or when batteries
become exhausted.

AUTO TIME SET

4. Pacific Standard Time (PST)
DAYLIGHT SAVING TIME
Slide the DST (Daylight Saving Time) switch on back of the unit to turn
Daylight saving time on/off. The clock comes with DST in the ON position
as the default. This setting is correct unless you live in Arizona or parts of
Indiana where DST is not observed.
