Mains power quality should be
that of a typical commercial or
hospital environment.
If the user of the Keeler Pulsair
IntelliPuff Tonometer requires
continued operation during
power mains interruptions, it is
recommended that the charger be
powered from an uninterruptible
power supply.

Portable and mobile RF communications equipment
should be used no closer to any part of the Keeler
Pulsair IntelliPuff Tonometer, including cables, than
the recommended separation distances calculated
from the equation applicable to the frequency of
the transmitter.

Where p is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey¹,
should be less than the compliance level in each
frequency range.²
