MODEL PS-1275A:

Two switches permit Battery Type and Charge Rate selection.

Switch #1 permits selection of either Conventional or Maintenance Free and Deep- Cycle batteries. If you are not sure of your battery type, use the (Regular) Conventional Setting.

Switch #2 (3 Charge Rate Modes)

Mode 1 – Select 2 amp automatic for 12 volt smaller (<31 AH [Ampere Hour]) or warm larger lead-acid batteries.

Mode 2 – Select 12 amp automatic for larger 12 volt batteries for a fast charge. Mode 3 – Select 75 amp Engine Start to assist in engine cranking of 12 volt systems.

DO NOT use on 6 volt systems. Use the 75 amp engine start position for cranking automobiles or light trucks. Use only with battery in the vehicle. This will reduce the chance of damaging sensitive electronic equipment in the vehicle.
