Common Faults & Maintenance
Battery leaks
The 535 and 535E have a Varta NiMH battery inside that is extremely prone to leaking. Remove it ASAP from any one of these that you have. The 535X does not have this battery inside.
Other Notes
The LCD on any of the models in this series are prone to developing Vinegar Syndrome, especially so since these were only sold in Japan.
