Using this throttle is easy. First, connect it to your Phaserunner or Baserunner via the Main9 Plug. Make sure the power is off during the connection. Then, turn on the On/Off Power Switch to start using the throttle. You can see the battery voltage on the numeric readout. To use the front lights, plug them into the 5.5 x 2.5mm DC Jack. For regen braking, connect your brakes to the 4pin JST - SM Ebrake Plug. When it comes to maintenance, keep the throttle clean and dry. Avoid exposing it to extreme temperatures. If you notice any issues with the voltage readout or other functions, check the wiring connections first. Also, make sure the battery voltage is within the 12V - 95V range for proper operation.
