Procedures 1
[1] PRF Fine Tuning
• Fine-tune the transmitting repetition frequency of the
transmitter in the range 90 to 100%.
• If radar's interference patterns are concentrically displayed,
increment or decrement the set value by 3 to 4 in order to
heighten the effect of interference rejection.
• The same operation can be performed by pressing the
[TX/STBY] key several times.
• One of 32 levels 0-31 can be set.
[2] Jamming
• Use the jamming function to control the transmitting repetition frequency of the transmitter.
• This function is effective when interference patterns caused by radar equipment of the same model do
not disappear.
[4] XMIT Repitation FREQ
• Select the operation mode the transmitting repetition frequency of the transmitter.
Press [RADAR MENU] key twice.
Press [5] key.
The TRX Setting Menu will appear.
Detail information about antenna operation can

NORMAL Standard mode:
ECONOMY Power saving mode:
HI POWER High sensitivity mode: Sensitivity improves when long pulses are used,
Both appropriate sensitivity and magnetron's life
expectancy are maintained.
Sensitivity slightly lowers, but the service life of
magnetron is prolonged when short pulses are
used.
but the service life of magnetron is slightly
shortened.
