4 Attention

This section includes some precautions that should be paid attention to for HUNTER 2.0 use and development.

4.1Battery

The battery supplied with HUNTER 2.0 is not fully charged in the factory setting, but its specific power capacity can be displayed on the voltmeter at real end of HUNTER 2.0 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 -10℃ to 45℃; 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.

HUNTER 2.0 only supports the replacement and use of the battery provided by us, and the battery can be charged separately.

4.2 Operational environment

The operating temperature of HUNTER 2.0 is -10℃ to 45℃; please do not use it below -10℃ and above 45℃ ;

The requirements for relative humidity in the use environment of HUNTER 2.0 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), HUNTER 2.0 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

For the extended power supply on top, the current should not exceed 10A and the total power should not exceed 240W;

For the extended power supply of top and tail, each ports must not be greater than 24V10A, the total output current must not be greater than 15A, total power should not exceed 360W.

When the system detects that the battery voltage is lower than the safe voltage class, external power supply extensions will be actively switched to. Therefore, users are suggested to notice if external extensions involve the storage of important data and have no power-off protection.

4.4 Other notes

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

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