APPENDIX
The Slave Display Unit will not change the radar video even if the tuning control is adjusted
because the tuning is controlled by the Master Display Unit. The tuning indicator at the
upper left of the display will show "SLAVE".
The change of the range scale on the Slave Display Unit depends upon the range scale on
the Master Display Unit. In general, the Slave Display Unit can not change the range scale
into a higher one than that on the Master Display Unit. However, a higher range scale may
be selected by the Slave Display Unit if the pulse length/repetition frequency is the same as
on the Master Display.
Scanner Safety Switch
If the Scanner Units are changed over in the condition that the safety switch of one Scanner
Unit is set to "OFF" while the other is set to "ON", "SSW OFF" will be indicated on both the
display.
