Guidance and Manufacturer's Declaration: Electromagnetic Immunity
AHTO Irrigation Pump is intended for use in the electromagnetic environment specified below. The
customer or the user of AHTO Irrigation Pump should ensure that it is used in such an environment.
NOTE: Ut is the a.c. mains voltage prior to application of the test level.

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.
