Rio 4+ When switched on no bleeps and green light is on. As soon as forward or reverse is selected bleeps start and switch off to stop. Battery been on charge for 16 hours and reads 26v off load. Have checked the micro switch on the drive/frere wheel knob. Any ideas please.

If the Medicare Technology Rio Series 4+ is not functioning properly despite a fully charged battery, possible issues include:

1. Charger still plugged in – Unplug the charger before use.
2. Motor in freewheel mode – Re-engage the freewheel lever.
3. Circuit breaker tripped – Push the circuit breaker button to reset.
4. Fault on the scooter – Ensure the wigwag paddle is released, then turn the scooter off and on again.

These checks can help diagnose why the scooter is not operating even with a fully charged battery.

    This portion of the content will provide the user with basic information that describes the problems with EMI, known sources of EMI, protective measures either to lessen the possibility or exposure or to minimize the degree of exposure, and suggested action should unexpected or erratic movement occur. Attention: It is very important that you read this information regarding the possible effects of electromagnetic interference on your Rio scooter.
  • Page 8 2.4.2 POWERED SCOOTER ELECTROMAGNETIC INTERFERENCE (EMI) Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EM energy very close to the control system of the scooter while using these devices.
