• Expect a communication range of approximately 2.6 Nautical Miles (5 km) in open sea areas. In urban environments, the range may be around 2.8 km, depending on obstructions.
• Always ensure the charging port cover is securely closed when near water to maintain the IP67 waterproof rating.
• Utilize the selectable 3W/1W power output: 3W for maximum range when needed, and 1W to conserve battery life during shorter-range communications.
