Portable and mobile RF communications equipment should be used no closer to
any part of the Keeler K-LED II or chargers, including cables, than the
recommended separation distances calculated from the equation applicable to
the frequency of the transmitter.

Note 1 At 80MHz and 800MHz, the higher frequency range applies.
Note 2 These guide lines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
¹ Field strengths from fixed transmitters, such as base stations ( 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 Keeler K-LED II / charger is used exceeds the applicable RF compliance level above, the Keeler K-LED II / charger should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orientating or relocating the Keeler K-LED II / charger.
² 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 Keeler K-LED II / charger
The Keeler K-LED II and charger are intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Keeler K-LED II / charger can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Keeler K-LED II / charger as recommended 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 metres (m) can be determined
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.
