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.
