Basic Information & Instruction:
If you`re not skilled or comfortable with Electronics, Soldering, and Safety you should not be purchasing this chip! It is intended for experienced individuals.

The USB is pre-soldered so there are only 3 connections and you should already know what these are but:

- White is your power out. Connect to center pin of your connector
- Red. Battery + (positive) connection
- Black. Battery - (negative) connection
- There needs to be a final connection for return path which is to the case or outside of your connector to your battery negative

As standard, there is no reverse polarity protection. To add this, you will need to move the black lead from its current location to the Bat-. Please see the SX350 Wiring Guide & Technical Information page for more information.

Once connected press the fire button 5 times to turn the unit on.


- Press 3 times to Lock
- Press 3 times to Unlock
- Press 5 times to enter menu

Once in the menu it will come up in your power settings at a preset. There are 5 presets M1 to M5.

To set, enter the menu and tilt the unit left. This will jump from preset to preset.
Select the preset you want to adjust. Tilt the unit to the right and it goes into adjust mode. Adjust to the level you desire for that preset and once there press the fire button to the next menu.
Exit and lean the unit and you are out of the program. Repeat above steps for each preset.

All functions in the menu:
