When routing 
RCA 
cables, keep the 
cables 
away from the power 
cables 
and output 
speaker wires. 
•  If 
you are using a source unit without a remote turn-on 
lead, 
the 
EQS755 can 
be 
turned 
on 
with a switched accessory 
lead. 
This accessory power source is located 
in 
the 
factory harness at the back 
of 
the radio. This lead 
turns on and off with the ignition 
key. 
• 
Do 
not open the case. There are no user-serviceable parts inside. If 
you require 
assistance, consult your 
Clarion 
dealer or

authorized Clarion 
service center. 
Tools 
and additional 
components 
You 
will 
need: 
• 
A Phillips-head screwdriver when mounting the unit

•  A 
small flat-head screwdriver to adjust theAUX gain controls if you connect 
an 
MP3 
player or video source. 
• 
High-quality 
RCA 
input and output cables. 
Extra 
cable 
can cause signal 
loss 
and act as 
an 
antenna for noise. Use 
only 
highquality 
RCA 
cables that are no 
longer 
than necessary to make a direct connection with the source 
unit and amplifiers.
