Why is my Marantz CD5003 CD Player remote controller not working?
- CCharles StokesAug 19, 2025
The remote controller might not be working due to several reasons: * The distance between the unit and the remote controller might be too great. Try using the remote controller nearer the unit, within the operational range. * There might be an object placed between the unit and the remote controller. Remove any objects that could be blocking the signal. * The batteries in the remote controller may be exhausted. Replace all the batteries with new ones. * The remote sensor of the unit could be exposed to strong light. Avoid exposing the remote sensor to strong light. * The REMOTE CONTROL switch on the rear panel might be set to EXTERNAL. When using the unit alone, ensure the switch is set to INTERNAL.
