CONNECTION CHECK LIST
Please check your head unit for the conditions
listed below:
Remote Turn-On Lead
a. The head unit does not have a remote turn-on
or power antenna lead.
b. The head unit’s power antenna lead is activated
only when the radio is on (turns off in the tape
or CD Mode).
c. The head unit’s power antenna lead is logic level
output (+) 5 V, negative trigger (grounding
type), or cannot sustain (+) 12 V when
connected to other equipment in addition to
the vehicle’s power antenna.
If any of the above conditions exist, the remote
turn-on lead of your R-A90S must be connected
to a switched power source (ignition) in the
vehicle. Be sure to use a 3 A fuse as close as
possible to this ignition tap. Using this
connection method, the R-A90S will turn on and
stay on as long as the ignition switch is on.
If this is objectionable, a SPST (Single Pole,
Single Throw) switch, in addition to the 3 A fuse
mentioned above, may be installed in-line on
the R-A90S turn-on lead. This switch will then be
used to turn on (and off ) the R-A90S. Therefore,
the switch should be mounted so that is
accessible by the driver. Make sure the switch is
turned off when the vehicle is not running.
Otherwise, the amplifier will remain on and
drain the battery.
