Check the following:
- Ensure the Bluetooth on the OdysseyControl is turned on.
- Ensure the switch on the BatteryPlus35 Remote Switch input is not activated.
- Ensure the BatteryPlus35 is not in Storage Mode as this will turn power to the OdysseyLink off, meaning the OdysseyLink cannot talk to the OdysseyControl.
If the BatteryPlus35 is in Storage Mode, the operational LED status indicator on the BatteryPlus35 will emit a single yellow flash.
Connect the BatteryPlus35 to a power source and begin battery charging. When the battery is sufficiently charged, communication between the OdysseyLink and OdysseyControl will automatically reestablish.
