Section 1 - Care, Warranty, and Service
1. Care and Safety
Never open the device, as there is a risk of electric shock. If necessary, contact Hitachi
Service.
Before Connecting the Machine to the AC Mains, one must ensure that the grid
Voltage meets the equipment’s settings.
Never expose the equipment to rain, moisture, or direct sunlight in order to avoid the risk
of fire or electric shock.
Avoid risks of accidents with regards heights and electricity. Always install or
maintain this equipment using qualified technicians.
Never turn on the equipment without connecting it to an Antenna or RF Load, as this may
cause serious damage to the Equipment.
Never unplug any Power Amplifier Drawers while the Transmitter is on, as this
may result in a risk of equipment damage.
