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-A75M/R-A60F 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-A75M/R-A60F 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-A75M/R-A60F turn-on lead. This switch will then be used to turn on (and off ) the R-A75M/RA60F. 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.
