Maintenance
Durability Features
The Armor X12 is IP68, IP69K, and MIL-STD-810H certified, meaning it is resistant to dust, water immersion, high-pressure water jets, and drops. To maintain these ratings:
- Ensure all port covers (USB, headphone jack, SIM tray) are securely closed before exposing the phone to water or dust.
- After exposure to water, especially saltwater, rinse the phone with clean fresh water and dry it thoroughly before charging or opening any ports.
- Avoid intentional drops from excessive heights, as the MIL-STD-810H rating covers specific drop test conditions.
