Power On And Start The System - JRC JMA-610 Series Instruction Manual

3.1.1 Power ON and Start the System

Attention
Wait for about 2 seconds before turning on the
power again.
At start of the system after the radar is installed,
after it has not been used for a long time, or after the
magnetron is replaced, preheat the equipment in the
standby state for 20 to 30 minutes before setting it
into the transmit state.
If the preheating time is short, the magnetron
causes sparks, resulting in its unstable oscillation.
Start transmission on a short-pulse range and
change the range to the longer pulse ranges in turn.
s
If the transmission is unstable in the meantime,
immediately place the system back into the standby
state and keep it in the standby state for 5 to 10
minutes before restarting the operation.
Repeat these steps until the operation is stabilized.
CAUTION
A malfunction may occur if the power in the
ship is instantaneously interrupted during
operation of the radar. In this case, the power
should be turned on again.
