EMC information
CAUTION
Avoid stacking or placing other equipment adjacent to
Power-PRO
and
SMRT
charger to prevent improper operation of
the products. If such use is necessary, carefully observe
Power-PRO
and
SMRT
charger and the other equipment to
make sure that they are operating properly.
Recommended separations distances between portable and mobile RF communications equipment and Power-
PRO and SMRT charger
Power-PRO
and
SMRT
charger are intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of
Power-PRO
and
SMRT
charger can help prevent
electromagnetic interferen ces by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and
Power-PRO
and
SMRT
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 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.
