The switches across the top of the radar control panel have the following functions:
- OFF - both radar systems are off.
- STBY - the selected RT entered a three minute warmup period.
- NORM - narrow beam scan for selected radar. The other radar is off. If NORM is selected immediately, the card will still go through its three minute warmup operation.
- CONT - [Contrast] blanks out returns of maximum intensity weather.
- MAP - provides expanded beam for ground mapping.
- TEST - projects a test pattern on scopes and illuminates all the control lights. The selected system also starts the warmup period.
The antenna is capable of stabilizing with the aircraft attitude of 25º roll and 15º pitch. Manual pitch tilting is permitted with the UP/DN pitch control knob on the right hand side of the panel.
The variable gain control switch on the left hand side of the panel allows amplification (gain up) of the radar return signal on the scopes. When in the AUTO position, the gain is automatically controlled.
