Alpine MRV-V500 Benutzeranleitung

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 (+) 5V, negative trigger (grounding type), 
or cannot sustain (+) 12V 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 MRV-V500 must be 
connected to a switched power source (ignition) 
in the vehicle. Be sure to use a 3A fuse as close 
as possible to this ignition tap. Using this 
connection method, the MRV-V500 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 3A fuse 
mentioned above, may be installed in-line on 
the MRV-V500 turn-on lead. This switch will then 
be used to turn on (and off ) the MRV-V500. 
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.
