Radar Initialize

Before adjusting, set the radar as follows: 
    IR: 2, ES: off, EAV: off, 24nm range, long pulse 
    (Same as default setting of PICTURE1) 
To adjust the cable attenuation manually, choose MANUAL and click the left button. Choose 
a value below the letter of MANUAL and rotate the wheel so that noise just appears on the 
screen when the gain is set to 80. Default setting is 30 for the antenna cable length of 15m. 
The setting range is 0 to 73. 
To adjust automatically, choose AUTO and click the left button. It takes about five minutes to 
complete the adjustment, after which the radar goes into stand-by.
