The earth bonding arrangement must ensure that the maximum peak voltage between the
unit case earth and any field cable conductor is less than 350V. Voltages in excess of this
can cause permanent damage to the unit's RFI protection filters.
Notes:
1.
Only Transmitters have turbo mode heating which can be disabled. The Receiver uses
proportional heating, which cannot be disabled.
2.
Even with turbo mode heating disabled the Transmitter window still receives standard
levels of heating.
3.
Do not reverse the Receiver power supply connections. This will not damage the unit,
but the unit will not function.
