Seiwa Radar tuning - Manual (Page 9)

2 Automatic and Manual Tune (non necessary at first
installation)
The Tune control is used to tune the receiver in the Radar antenna for maximum target
returns on the display. The radar comes from the factory already tuned so this operation is
not necessary at first installation. In general radar tuning may be necessary if any
component of the radar is replaced for maintenance.
The Radar receiver can be tuned in Automatic or Manual mode. In Automatic Tune
mode, the Radar tunes itself automatically on all range scales. It is recommended to
execute the Tune function in Automatic mode. This generally ensures that the Radar
receiver is always tuned to receive the maximum signal.
If you choose the Manual Tune, you will need to adjust it again after 10 minutes, after
you have turned on the Radar, since the required setting will change after the magnetron
has warmed
