NOTE If necessary, to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna
and the ME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1 m test distance is permitted by IEC
61000-4-3.
a)
For some services, only the uplink frequencies are included.
b)
The carrier shall be modulated using a 50 % duty cycle square wave signal.
c)
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it
does not represent actual modulation, it would be worst case.
During power outage, pump will stop functioning. It is suggested to be use with a stable power source or an uninterruptable
power supply source. The pump will return to its normal operation when power is resumed.
