Schumacher VTV-20 User Manual

Model: VTV-20

OPERATING INSTRUCTIONS

1. Plug the short cable into the 12V accessory port of the vehicle
with the good battery. Wait for the Power and Status lights to
glow steadily.

2. The long cable plug should now be lit. Plug this end into the
accessory port of the disabled battery. If the connection to the
disabled battery is good, the plug and status light will blink.
If the light does not blink, check your connections. Also, try
turning the engine ignition key to the ACC position.

3. The plug will blink continuously. Try starting the vehicle after 5
to 10 minutes or if the plug stops blinking. If the vehicle does
not start, the plug will continue to blink.

4. If the vehicle does not start after 5 to 10 minutes of charging,
wait 15 additional minutes before trying again. When the 15
minute waiting period is up, try starting again.

to hear a clicking noise while charging.
