How does First Aid for Noise work?

Simple Installation.

The unit is supplied with bolt type terminals so in the case of a single appliance or charger installation all you have to do is cut the positive and negative wires, and connect the filter in-line.

Connect the cables going to the battery to the terminals marked ‘battery’. Connect the cables going to the affected appliance or charger to the terminals marked Appliances / charger.

WARNING

The Filter is clearly marked with Battery on one side and Appliance / Charger on the other side, please note that accidentally installing the unit in reverse will not damage the unit, however noise filtration is unidirectional.

So noise and interference will not be eliminated when connected in reverse, so be careful to correctly install the filter as marked.

In the event of accidental reversed installation simply correct the direction of the filter and all noise and interference will once again be eliminated.
