has a protective cover with a label “Caution against high voltage” so that no one will accidentally touch
it. Please ensure for your safety that the power switch is turned off and residual voltage in the capacitor
is discharged in a suitable manner when checking the inside of the antenna. Maintenance and
inspection should be conducted by qualified engineers only.
Precautions for maintenance
•
Caution against residual high voltage:
Capacitors used in the Control Box and the modulator circuit of the transmission unit may keep high
voltage for several minutes even after turning off power. The maintenance and inspection of this part
should be performed at least 5 minutes after powering off or applying the appropriate measure to
discharge the residual electrical charge.
• Keep inboard power source “Off”:
An electric shock is possible if the power switch is accidentally turned on during the maintenance
operation. In order to prevent such an occurrence, please ensure to disconnect the power breaker of
the onboard power source and the device. Furthermore, it is recommended to post the word-of-caution
tag shown to be in a
“working state” near the power switch of the device.
•
Caution against the dust:
Dust can temporarily cause distress to the respiratory system. Take care not to inhale dust when
cleaning the interior of the device. It is recommended you wear a safety mask.
•
Measures against static electricity:
Static electricity occurring from carpet on the floor of the cabin, clothes made of synthetic fiber etc., may
damage some electronic parts on the printed circuit board. Please work on the printed circuit board only
after taking measures against static electricity.
•
Prohibited matter:
Any Control Box and Scanner unit combination other than specified in the manual is prohibited and will
void manufacturer’s warranty.
•
Break in procedure of stored radar:
Follo
wing procedure is recommended for “Break In” of the stored radar.
Otherwise the radar sometimes exhibits unstable transmitting operation such as arcing at its initial
operation after long period of storage and make the operation more difficult.
1. Extend preheat time as long as possible (preferably 20 to 30 minutes).
