Explanation Of Symbols - Philips DL8791 User Manual

Note 2: These guidelines may not apply in all
situations. Electromagnetic propagation is affected
by absorption and reflection from structures,
objects and people.
Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the device, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.Recommended separation distance
d = 1.17 √P
d = 1.17 √P 80 MHz to 800 Mhz
d = 2.33 √P 800 MHz to 2,5 GHz
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 meters (m). Field strengths
from fixed RF transmitters, as determined by an
electromagnetic site survey, should be less than
the compliance level in each frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
Field strengths from fixed transmitters, such
as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due
to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured
field strength in the location in which the device is
used exceeds the applicable RF compliance level
above, the device should be observed to verify
normal operation. If abnormal performance is
observed, additional measures may be necessary,
such as re-orienting or relocating the device.
Over the frequency range 150 kHz to 80 MHz,
field strengths should be less than 3 V/m.
Recommended separation distances
between portable and mobile RF
communications equipment and the
Medical device
The device is intended for use in an electromagnetic
environment in which radiated RF disturbances are
controlled. The customer or the user of the device
can help prevent electromagnetic interference by
maintaining a minimum distance between portable
and mobile RF communications equipment
(transmitters) and the device as recommended
below, according to the maximum output power of
the communications equipment.
Separation distance according to
frequency of transmitter

100 39ft 39ft 75½ft
For transmitters rated at a maximum output power
not listed above, the recommended separation
distance d in meters (m) can be estimated using
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.
Note 1: At 80 MHz and 800 MHz, the separation
distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all
situations. Electromagnetic propagation is affected
by absorption and reflection from structures,
objects and people.
Frequency range: 2400-2478 MHz.
Output power, highest setting: 5 dBm.
Modulation: 1-Mbps GFSK.
EMC Guidance
-
The device needs special precautions regarding
EMC and needs to be installed and put into
service according to the EMC information
provided in the accompanying documents.
-
Wireless communications equipment such as
wireless home network devices, mobile phones,
cordless telephones and their base stations,
walkie-talkies can affect this equipment and
should be kept at least a distance d = 3.3 m
(11 ft) away from the equipment.
Note: As indicated in IEC 60601-1-2:2007 for ME
equipment, a typical cell phone with a maximum
output power of 2 W yields d = 3.3 m (11ft) at an
immunity level of 3V/m.
FCC Compliance information
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any
interference received, including interference that
may cause undesired operation.
Radio interference
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses
and can radiate radio frequency energy and, if
not installed and used in accordance with the
instructions, may cause harmful interference
to radio communications. However, there is no
guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference
to radio or television reception, which can be
determined by turning the equipment off and
on, the user is encouraged to try to correct the
interference by one or more of the following
measures:
-
Reorient or relocate the receiving antenna.
- Increase the separation between the equipment
and receiver.
- Connect the equipment to an outlet on a circuit
different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV
technician for help.
RF Radiation exposure statement
This equipment complies with FCC RF radiation
exposure limits set forth for an uncontrolled
environment. For wrist-worn operation, this
equipment has been assessed and meets the
FCC RF exposure guidelines for portable devices.
Do not attempt to repair or modify this equipment.
Any repairs or alterations made by the user to the
equipment may void the warranty and compliance
of the equipment. Changes or modifications made
to this equipment not expressly approved by
Philips may void the FCC authorization to
operate this equipment. For assistance visit
