2.3 Turning the Radar On and
Off
Press the [POWER] key to turn the radar
on or off. The control panel lights and a
timer displays the time remaining for warm
up of the magnetron (the device which
produces radar pulses), counting down
from 1:30.
Note: When the power is reapplied within a
certain amount of time and circuits
remain charged, the warmup process
is skipped—you can transmit without
one and a half minutes st-by time.
The radar antenna emits high frequency radio
radiation which can be harmful, particularly to
your eyes. Never look directly at the antenna
from a distance of less than three feet when
the radar is in operation. Always make sure
no one is near the antenna before turning on
the radar.
WARNING !
