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 ACT Plus
exceeds the applicable RF compliance level above, the ACT Plus
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the ACT Plus
b
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 ACT Plus
®
The ACT Plus is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the ACT Plus
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the ACT Plus
below, according to the maximum output power of the communications equipment.

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: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
Cautions:
• Do not use non-Medtronic components with Medtronic in-line-powered external devices.
The use of non-Medtronic components may result in damage to Medtronic components,
increased emissions, or decreased electromagnetic immunity of the Medtronic devices
or systems.
• Do not use Medtronic in-line-powered external devices adjacent to, or stacked with,
other electronic devices. Using Medtronic devices in these configurations may result in
decreased electromagnetic immunity of the Medtronic devices or systems.
