What
to
do
• Check the settings on your receiver or amplifier Refer
to
the owner's guide that came with
it for instruction on settings
• If your
251™
speakers are connected as a second set
of
speakers
to
your receiver or
amplifier, check that the connections have been made
to
the
"B"
terminals and that
the
"B"
speakers are selected
to
play
• Check the tonal balance setting on your receiver or amplifier
• Check the balance control on your receiver
or
amplifier and make sure it's centered
• Check the wires connected
to
the speaker that does not play Make sure the wires are
in
good condition and are firmly connected Review the "Making the connections" section on
page 9
• Disconnect the working speaker from the receiver or amplifier
• Switch the cord
of
the "faulty" speaker from its original receiver or amplifier jacks
to
the
other set
of
jacks (the working speaker was originally attached to those jacks)
- If the speaker
now
works, the problem is
in
your receiver or amplifier Reconnect your
speakers
to
a working unit
- If there is still no sound from the speaker, continue below
• Remove the cord from the working speaker and connect it
to
the "faulty" speaker
- If the speaker now works, the problem was
in
the original speaker cord

in
the speaker

Cleaning your
speakers
Use a cloth dampened
in
mild detergent and water
to
remove dust
or
dirt from the outside
of
your
251
speakers Or use a hose
to
rinse them thoroughly with fresh water Do not use
enough pressure
to
force water behind the grille and into the drivers
or
the acoustic ports
Protecting
the
speaker
wire
The bare ends
of
the speaker cord can be affected by exposure to the elements This is
especially true
of
saltwater exposure
You
may use a silicone caulking material, such
as
RN
adhesive,
to
protect the connections It is commonly available at hardware stores If you do
use caulking, apply it only after the wires are connected and the knobs tightened down
Check the connections annually, and reapply as needed
