 | The product design allows the battery to be changed with the B&R device switched either on or off. In some countries, safety regulations do not allow batteries to be changed while the module is switched on. |
| Any BIOS settings that have been made will remain when the battery is changed with the power turned off (stored in nonvolatile EEPROM). The date and time must be reset later since this data is lost when the battery is changed. |
| The battery is only permitted to be replaced by a Renata CR2477N battery. The use of another battery may present a risk of fire or explosion. The battery may explode if handled improperly. Do not recharge, disassemble or dispose of in fire. |
