1>. The maximum working current is 5V 2A. Better sound quality when using 5V 2A or higher. We recommend using a 3.7-5V lithium battery. (The lithium battery should have charging protection!)
2. Dual 5 W stereo amplifier:
1>. The Bluetooth audio receiver card already has a double 5W power amplifier circuit. No need to connect an additional power amplifier. The output of double amplifiers cannot be connected in parallel or connected to the negative electrode, otherwise the power amplifier chip will be damaged.
3. How to use:
1>. Open the Bluetooth function of your mobile phone or other devices with Bluetooth function (such as laptops, tablets, etc.). Please delete other previously paired Bluetooth devices from your phone in case the Bluetooth connection is unstable.
2>. The phone automatically searches for the module labeled "DW-CT14+" and pairs it without the need for a pairing code or button.
3>. The LED of the module starts flashing after Bluetooth connection.
4>. It will automatically connect to an already paired device and automatically shut down after 10 minutes in standby mode.
4. Note:
1>. For your safety, use a normal lithium-ion battery with charging protection.
2>. Please use a stable power supply such as a 3.7V 5V lithium battery or a 5V power supply. Do not use disposable batteries, power banks, multifunctional transformers and other power supplies with unstable voltage and unstable current.
3>. The antenna should be far away from metal materials so as not to affect the transmission distance.
