Many new and factory radios require a reset code when disconnected from
battery power. This is an anti-theft feature. Before unplugging power, you must
determine
if
your radio/source unit requires a reset code. Check the operation
manual for your vehicle or contact the dealer.

This is a critical step to insure
your
amplifier
is properly adjusted to match the signal
output level
of
your
source unit.
THIS IS NOT A VOLUME CONTROL! . .
MIN
MAX
1.
If
possible, with the source unit
off
, confirm that the primary volume control
is
turned down (counter clockwise).
2. Turn on the source unit (CD,
or
MP3
player). Re-confirm that the volume is
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center
or
"O
" adjustment. Make sure that the green LED on
the end
of
the amplifier
is
illuminated.
3. Play a clean musical selection
of
which you are very familiar. CD is preferred.
Do not use radio signals
for
level setting. Hit play and start turning the volume
of
the source unit up.
4. Stop increasing the source unit volume when you reach 3/4 (about 75%)
or
until
you hear speakers begin to slightly start producing distortion.
5. Increase the amplifier gain (clockwise) until distortion is heard, then back
the level down (counter clockwise) until the distortion is eliminated. Small
adjustments may need to be made
to
balance the levels
of
multiple amplifiers.
