COMMISSIONING
23 The Transmitter Interface Unit (NNR-A66) is fitted with
a power On/Off switch on the top of the unit.
24 Set the power unit to provide an antenna rotation
supply of either 27V (normal speed units) or 36V (high
speed units).
25 There is no specific commissioning procedure
applicable to the Transmitter Interface Unit.
