2.1
Switching the Radar System On and Off
Switching the radar system ON is done by means of one of the ON/OFF switches or
POWER buttons situated on the radar indicators. When this is done, all indicators and
transceivers are switched on.
 1)
 and
After the warm-up phase of the magnetron - 3 minutes for X-Band and 3.5 minutes for S-Band - stand-
by operation is achieved and the radar function can be switched on; see 
The act of switching an indicator on never causes a transceiver to be switched directly into radar
Mode.
If an attempt to switch over to radar operation occurs before stand-by operation is achieved, the indi-
cation WARM UP appears instead of the list of transceivers.
Switching the radar system OFF: Switch off all indicators by means of the ON/OFF switch
 2)
. As long
as there is one of the switches in the ON state, all electronics units of the indicators and transceivers
remain switched on and.
Stand-By Operation
The main difference between stand-by operation and radar operation is that, during stand-by operation,
the transceiver is not transmitting and the antenna is not rotating. Therefore, the radar video is absent on
the PPI, and none of the functions that depend on the transceiver can be operated yet.
During stand-by operation, the magnetron is kept at its operational temperature.
1)  
If an display electronics unit is exposed to very low temperatures (around -15°C or less), it can happen that its computer does not start up.
The screen of the associated monitor then remains dark, or becomes dark after a short time. In this case, the radar system must remain
switched on for about 30 minutes (in spite of the dark screen) so that the display electronics units will warm up. If the radar system is then
switched off and is switched on again after a waiting time of a few seconds, the computer will start up in the normal way.
2)  
If a indicator has a POWER key, that indicator is switched off by prolonged pressing of this key.
