Guidelines and Statement of Manufacturer - Electromagnetic Immunity
The instrument is expected to be used in following specific electromagnetic environments, and
the purchaser or the user should ensure that it is used in these electromagnetic environments:

The distance between
portable or mobile RF
communication device and
any used part (including
cable) of DBP-01H should
not less than the
recommended isolation
distance. The distance
should be calculated by the
formula corresponding to
the transmitter frequency.
