4 Precautions

This section includes some precautions that should be paid attention to for TRACER use and development.

4.1 Battery

The battery supplied with TRACER is not fully charged in the factory setting, but its specific power capacity can be displayed on the voltmeter at rear end of TRACER chassis or read via CAN bus communication interface. The battery recharging can be stopped when the green LED on the charger turns green. Note that if you keep the charger connected after the green LED gets on, the charger will continue to charge the battery with about 0.1A current for about 30 minutes more to get the battery fully charged.

Please do not charge the battery after its power has been depleted, and please charge the battery in time when low battery level alarm is on;

Static storage conditions: The best temperature for battery storage is -20℃ to 60℃; in case of storage for no use, the battery must be recharged and discharged once about every 2 months, and then stored in full voltage state. Please do not put the battery in fire or heat up the battery, and please do not store the battery in high-temperature environment;

Charging: The battery must be charged with a dedicated lithium battery charger; lithium-ion batteries cannot be charged below 0°C (32°F) and modifying or replacing the original batteries are strictly prohibited.

4.2 Operational environment

The operating temperature of TRACER outdoors is -10℃ to 45 ℃;please do not use it below -10℃ and above 45℃ outdoors;

The operating temperature of TRACER indoors is 0℃ to 42℃; please do not use it below 0℃ and above 42℃ indoors;

The requirements for relative humidity in the use environment of TRACER are: maximum 80%, minimum 30%;

Please do not use it in the environment with corrosive and flammable gases or closed to combustible substances;

Do not place it near heaters or heating elements such as large coiled resistors, etc.;

Except for specially customized version (IP protection class customized), TRACER is not water-proof, thus please do not use it in rainy, snowy or water-accumulated environment;

The elevation of recommended use environment should not exceed 1,000m;

The temperature difference between day and night of recommended use environment should not exceed 25℃;

4.3 Electrical/extension cords

When handling and setting up, please do not fall off or place the vehicle upside down;

For non-professionals, please do not disassemble the vehicle without permission.

4.4 Additional safety advice

In case of any doubts during use, please follow related instruction manual or consult related technical personnel;

Before use, pay attention to field condition, and avoid mis-operation that will cause personnel safety problem;

In case of emergencies, press down the emergency stop button and power off the equipment;

Without technical support and permission, please do not personally modify the internal equipment structure.

4.5 Other notes

When handling and setting up, please do not fall off or place the vehicle upside down;
