Most RockJam keyboards require a DC 9V power adapter (often 500mA or 1000mA depending on the model) with a center-positive plug. Always check the specific voltage rating on the back of your device or in the user manual.
Turn on your karaoke party speaker and switch it to Bluetooth mode (you may hear a sound signal). On your mobile device, search for the Bluetooth name (often 'RockJam' or the model number like 'RJPS150') and select it to pair.
A faint click or static noise when powering the keyboard on or off is normal for many electronic keyboards and does not indicate a fault.
Many RockJam models, such as the RJ493 or RJ549, feature MIDI capabilities or AUX connections. Check if your model has a USB MIDI port (Type B or Type C) to connect to a tablet, laptop, or PC for use with music software.
