SHOOTING
3.1
Maintenance
Regular maintenance is important for good performance. Check the points mentioned
below every 3 to 6 months to keep the radar sensor in good working order. Observe
the safety instructions at the front of this manual when working on the mast.
3.2
Replacement of Fuse
The 5A fuse (Type: FRU-2P5S-FU-5A-A, Code No.: 000-168-869-10) in the fuse hold-
er on the cable assembly protects the radar sensor from overcurrent and equipment
fault. If you cannot turn on the power, check the fuse to see if it has blown. If the fuse
has blown, find the reason before you replace the fuse. If the fuse blows again after
the replacement, contact your dealer for advice.

• Cracks
• Foreign material
If a crack is found, repair it temporarily with a small
amount of sealing compound or adhesive. Bring the unit

freshwater-moistened cloth. Do not use commercial
cleaners to clean the sensor; they can remove paint and
markings or deform the plastic.
