Prevent shut-down
and return to pre-
interference state
after manipulation
by operator.
(Power-on switch)
The quality of the main power
supply should be equivalent to that
of commercial or hospital settings.
If the HF-525 PLUS is to be
operated without a sufficient main
power supply, it is better to provide
the appropriate power using UPS or
battery.

Electromagnetic Susceptibility
HF-525 PLUS is manufactured to be used in the electromagnetic environment designated in the below table.
The user of HF-525 PLUS should check whether the equipment is used in such an environment.

Portable and mobile RF communication equipment
must not be used from a distance closer than the
recommended separation distance, which is
determined by an equation that calculates the
distance from all parts of HF-525 PLUS (including
the cables) to the transmission frequency.
Recommended separation distance
80MHz to 800 MHz
800MHz to 2,5 GHz
P is the maximum rated output (W) of the
transmitter according to its manufacturer, and d is
the recommended separation distance (m).
The field intensity
a
from fixed RF transmitter that is
detected by measuring electromagnetic waves
should be lower than the compliance standard in
each frequency range
