A The test is applicable only to equipment potentially sensitive to
magnetism. CRT display interruption value is allowed to be higher than
1A/m.
B Only applicable to cables longer than 3m.
C Not applicable to input port expected to connect to battery or
chargeable battery (before recharging, it should be removed or
disconnected from the equipment). For equipment with DC power input
port (using AC-DC power adapter), test should be conducted on AC input
port of AC-DC power adapter specified by the manufacturer. If there is no
specific requirement, typical AC-DC power adapter should be adopted. The
test is applicable to DC power input port designed for extended long
distance connection.
D “5/6cyle” refers to “5 cycles under 50Hz test” and “6 cycles under 60Hz
test”.

Radio-frequency emission
GB 4824
Type A
The equipment is designed and tested based on Type-A equipment in GB4824. In family
environment, the equipment may cause radio interference, and thus protective measures should
be taken.
Electromagnetic environment evaluation is suggested before the equipment use.
