2. Safety Instructions

WARNING: Failure to follow these safety instructions can result in fire, property damage, or serious injury.

• Always operate the charger in a well-ventilated area, away from flammable materials.
• Never leave the charger unattended while in use.
• Ensure the correct battery type and charging parameters are selected before starting any operation. Incorrect settings can damage batteries or cause hazards.
• Do not charge two different batteries on the same channel simultaneously. Each channel is designed to charge one battery at a time.
• Avoid using the AC power cable and DC cable simultaneously.
• Keep the charger away from water, moisture, and extreme temperatures.
• The cooling fan may produce sound during operation; this is normal for heat dissipation. Do not obstruct the fan vents.
• Always use appropriate fire-resistant charging bags or containers for LiPo batteries.

5. Setup

Follow these steps to set up your HTRC T240 DUO charger:

1. Connect Power: Plug the AC power cable into the AC input port (100-240V) on the back of the charger and then into a wall outlet. Alternatively, for DC input (11-18V), connect the XT60 DC cable to the DC input port and to a suitable DC power source. Ensure only one power source is connected at a time.
2. Power On: Flip the ON/OFF switch on the back of the charger to the 'ON' position. The touch screen will illuminate.
3. Connect Main Plug: Connect the main plug of your battery to the output port (CH1 or CH2) on the front of the charger.
4. Connect Balance Extension Cord: For balance charging, connect the balance extension cord from your battery to the corresponding balance socket on the charger. Ensure the connection is correct, typically from right to left (negative to positive).
