Electromagnetic Compatibility
The use of ALGO 7i devices in close proximity to other electronic equipment or with other
electronic equipment in a stacked form should be avoided, as this could result in improper
operation (e.g. occurrence of unwanted noise). Electronic equipment may include e.g.
mobile phones, pagers, walkie-talkies, or RFID systems. If such an application cannot be
avoided, ALGO 7i and the other electronic devices should be observed to make sure they
are working properly. It may be necessary to implement suitable corrective measures
(e.g. new orientation or positioning of ALGO 7i or shielding). Please also refer to section
10: Electromagnetic Compatibility Information.
Portable radio frequency communications equipment (radio equipment) including their
accessories such as antenna cables and external antennas should not be used closer than
30 cm (12’’) to
the ALGO 7i and its accessories.
During testing it is recommended to keep low-power radio equipment
(≤ 2 W)
at a
distance of at
least 3 m (118’’)
from the ALGO 7i and its accessories.
It is recommended to keep very strong sources of radio frequency emissions (e.g. high-
power transmitting antennas from radio or TV stations) at a distance of at least 2 km
(6560 ft.) from ALGO 7i (minimum required distance depends on signal power and
directional characteristics of the sender).
Failure to do so may result in a reduction of device performance.
Use of other accessories than the ones specified or provided by PATH MEDICAL may result
in higher electromagnetic emission or reduced immunity to interference of the device
and may result in improper device operation.

Accessories
The Flexicouplers and Jelly Tab sensors are marked
“
single use only
”
and must be
replaced between patients to avoid cross-infection. Do not clean or reuse these items.
Do not connect any accessories other than those supplied by Natus Medical. Accessories
other than those specified by the manufacturer are not compatible with the device and
may result in device damage or improper functionality of the device. If connecting
accessories which do not comply with the same safety requirements as this product, this
may lead to a reduction in the overall system safety level.
Cleaning the device and its accessories is very important for compliance with hygienic
requirements and to avoid any cross-infection. For further information please refer to
section
Always handle cables and transducers with care. Do not excessively bend or twist any
cable. The cable may break and hence deteriorate overall device functionality or reduce
the overall system safety level. Do not drop, throw or hit any transducer on a hard object.
Sensitive parts (e.g. ATA Cable microphone and loudspeakers) may get damaged and
deteriorate measurement performance. Do not use a cable or transducer if any damage
is suspected.
