The battery indicator may red and the buzzer may beep periodically when the battery is powered on but is not properly connected to the Jet unit.
a. Turn off the device.
b. Connect the Jet to the battery using the connection cable.
c. Turn the device back on.
2. Check the connectors and ports for water or moisture.
Water remaining inside the connectors or ports may affect communication between the battery and the Jet. If any, dry the connectors thoroughly before reconnecting.
If the issue continues, please provide:
1. A short video showing the red indicator light and beeping behavior while the battery is connected to the Jet.
