5.Dimension

Remark:

1, radio power supply requirements: The maximum output current is not less than 2A, and the linear DC power supply is the best choice. If using switching power supply, the power supply with smaller ripple and better EMC characteristics should be selected.

2, the radio must be connected the antenna before the radio is powered on, a long-time antenna open-circuit working may cause damage to the radio.

6.Accessories

1.Standard accessory:

DB9connector

Small sucker antenna (Users can select high gain antennas for better communication results according to actual use.)

3.5 4-band audio plug
