Network power quality should be
qualified for typical hospital or
commercial environments. If
users need continuous infusion
even during power interruption, it
is recommended to use UPS or
battery.

Portable and mobile RF communications device should
not be closer than the recommended separation distance
from any part of WIT-601 Infusion Pump; the distance
shall be calculated using the formula corresponding to the
transmitter frequency.
Recommended separation distance
80MHz to 800 MHz
800MHz to 2.5 GHz
If p is the maximum rated output power (watts) provided
by RF device manufacturer, then d is the recommended
separation distance (m). (b)
Fixed RF transmitter’s field strength is determined
through electromagnetic site survey; each frequency band
should be lower than the line Compliance level. (a) (b)
