How to use the “BOOST BUTTON” on the XP-3 Smart Clamps?

In most situations, you will not need to use the Boost Button on the Smart Clamps. The “Boost” Button is designed to allow for Jump Starting a Vehicle when the battery has very low voltage or no voltage reading. In these emergency situations, the “Boost” Button allows the jump starter clamps to be energized to start the Vehicle for emergency Boost Starting.

CAUTION MUST BE USED WHEN PRESSING THE BOOST BUTTON! THE CLAMPS ARE LIVE WITH ENERGY ONCE PUSHED.

WARNING PLEASE NOTE THE FOLLOWING.

A) The Smart-Clamps must be connected to the XP-3 for the “Boost” Button to operate. It needs power.

B) BEFORE pressing the “Boost” Button double check to make sure all connections are correct. Once the “Boost” Button is pressed the Clamps will have “live” 12v voltage at the Clamps. Always connect Red Clamp to Positive (+) Terminal of Battery. Black Clamp to Negative (-) Terminal of Battery.

C) You will hear a “click” when you have pressed the boost button correctly, you may need a pen, fingernail or edge of a key to press the button correctly due to the “Boost” Button being indented in the Smart-Clamp Housing.

D) Once the “Boost” Button is pressed you will have 25 seconds to attempt your jump-start. After that time the “Boost” will turn-off. You will need to press the Boost Button again to re-engage the Boost feature.
