Recommended separation distances between portable and mobile RF communications equipment and
the EQUIPMENT or SYSTEM for EQUIPMENT or SYSTEM that ara not LIFE-SUPPORTING
Guidance and manufacture's declaration- electromagnetic immunity
NOTE 1 At 80 MHz and 800 MHz, 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
a
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 Sphygmomanometer
(MD2520/MD2540/MD2580) is used exceeds the applicable RF compliance level above, the Sphygmomanometer
(MD2520/MD2540/MD2580) should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Sphygmomanometer (MD2520/
MD2540/MD2580)
b
Over the frequency range 150kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the Sphygmomanometer (MD2520/MD2540/MD2580)
The Sphygmomanometer (MD2520/MD2540/MD2580) is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Sphygmomanometer (MD2520/
MD2540/MD2580) can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Sphygmomanometer (MD2520/MD2540/
MD2580) as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum oulput power not listed above, the recommended separation distance d in metres
(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 10 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 strucbJre8, objects and people.
Appendix IV
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 hwristful 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 hwristful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause hwristful
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 into an outlet on a circuit different from that to which the receiver
is connected.
- Consult the dealer or an experienced technician for help.
• To comply with the limits of the Class B digital device, pursuant to Part 15 of the FCC Rules,
this device is comply with Class B limits. All peripherals must be shielded and grounded.
Operation with non-certified peripherals or non-shielded cables may results in interference
to radio or reception.
• Any changes or modifications not expressly approved by the grantee of this device could void
the user's authority to operate the device.
WARNING
Symbol for the marking of electrical and electronics devices according to Directive 2002/96/EC.
The device, accessories and the packaging have to be disposed of waste correctly at the end of
the usage. Please follow Local Ordinances or Regulations for disposal.
