• To ensure the signal transmission, it is recommended to set up the relay at least 2 m higher than the
crops.
• DO NOT obstruct the antennas during use.
• DO NOT set up the relay outdoors during thunderstorms to avoid lightning strikes.
• The relay should be used in the temperature range of 0° to 40° C (32° to 104° F). High temperatures
can lead to fire or an explosion. Low temperatures can negatively affect the performance of the
battery.
• The battery temperature will be high after use. Charge the relay until it cools down to room
temperature. Otherwise, charging may be disabled. Charge at a temperature range of 5° to 40° C (41°
to 104° F). The ideal charging temperature range is 22° to 28° C (72° to 82° F). Charging within the
ideal temperature range can prolong battery life.
• Extinguish any battery fire using water, sand, or a dry powder fire extinguisher.
• The electrolytes in the battery are highly corrosive. If any electrolytes make contact with your skin or
eyes, wash the affected area with water and see a doctor immediately.
