the device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the PABLO® system.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [4] V/m.
Table 4: Guidelines and Manufacturers‘s declaration – Electromagnetic Immunity
Recommended separation distances between portable and mobile RF communications
equipment and PABLO® system
The PABLO® system is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. Users of this device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communication equipment
(transmitters) and the device as recommended below, according to 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.
NOTES:
- At 80 MHz and 800 MHz, the higher frequency range applies.
- These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
