ALTERNATIVE AMPLIFIER TURN-ON OPTIONS (Fig. 3)
If your head unit does not have a traditional amplier turn-on lead, refer to the options
below for connection.
Please check your head unit for the conditions listed below: (Fig. 3)
a. The head unit does not have a remote turn-on or power antenna lead.
b. The head unit's power antenna lead is activiated only when the radio is on (turns off in
Bluetooth 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
KTA-200M 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
KTA-200M 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 KTA-200M turn-on lead. This switch will then
be used to turn on (and off) the KTA-200M. 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 amplier will remain on and drain the battery.
