Contact
Air
Note:
Test method complies with IEC 61000-4-2 [5].
In addition to the protection measures specified in the user's documents, ESD measures should be taken
to all exposed surface of equipment to be tested.
IV. RF induced currents
In CDMA equipment, the port where a cable of more than 1 meter may be connected to,
including control port, DC input/output port and the input/output port of the connection
line when cabinets are combined, should satisfy the requirements for RF induced
currents. The indices are shown in Table B-6.

Signal line port and control line port
Note:
Test method complies with IEC61000-4-6 [9].
V. Surge immunity
For CDMA equipment, the DC power input port, indoor signal line of more than 3 m,
control line (such as E1 trunk line, serial port line) and the cable that may be led out to
