What are the steps to install a memory card in FirstDefender RMX?

• A. Shut down detector, open access door
• B. Power on, insert card, restart
• C. Connect USB, copy data
• D. Remove battery, insert card, reboot

Answer: (A)

Safe device maintenance and handling procedures require ensuring the unit is not powered when you access its internal components. Shutting down the detector eliminates power, reducing the risk of short circuits or data corruption as you insert the memory card. Opening the access door then provides the physical entry to reach the memory card slot, allowing you to seat the card properly without forcing anything while energized. The other options involve operating the unit during the installation, which can cause damage or unsafe conditions, or describe data transfer methods rather than installation, or remove the battery in a way that isn’t the standard safe sequence. Following a powered-down state and access to the slot is the proper approach.
