Attentions
1）The input power shall not exceed 10dBm to avoid damage.
2）Always connect antenna before power on, never power on without antenna load.
3）Power supply range 24-28V, clean power source recommended：24V with 2A current，28V with 1.5A current
4）Keep good ventilation for heat dissipation，adding heat sink or radiator fan is recommend.
5）Comply with local radio spectrum regulatory requirements.
