5. Maintenance

5.1 Waterproof and Floating Features

Figure 5.1: The Retevis RM22 is IP67 waterproof and designed to float, making it resistant to saltwater and easy to find.

The RM22 is IP67 rated, meaning it is protected from dust and can withstand immersion in water up to 1 meter for 30 minutes. If the radio falls into water, it will float and activate a flashing indicator light to aid in recovery. After exposure to saltwater, it is recommended to rinse the radio with fresh water and dry it thoroughly to prevent salt buildup and corrosion.

5.2 Cleaning and Storage

• Wipe the radio with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure the charging port cover is securely closed when not charging to maintain water resistance.
• Store the radio in a cool, dry place when not in use, away from direct sunlight and extreme temperatures.
