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 S-A60M/S-A32F/S-A55V
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
S-A60M/S-A32F/S-A55V 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 S-A60M/S-A32F/S-A55V turn-on lead. This
switch will then be used to turn on (and off) the
S-A60M/S-A32F/S-A55V. 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.
