Acoustics buzzer alarms
When applying the inverter to acoustics devices, some inferior acoustics
devices will buzz, this is because the output wave from the inverter is modified
sine wave inverter�
TV Interference
You can get minimum interference through use of a filter� On some occasions,
when the interference of every weak signals becomes too obvious, you can try
the following:
• Place the inverter far from the TV and TV antenna�
• Try to change the direction of TV signals cable and TV antenna to reduce the
interference to minimum�
• Use screen cable antenna of highly quality�
