For this reason the chain counter must be at least:
• 25 cm from the compass.
• 50 cm from any radio receivers.
• 1 m from any radio transmitters (except for SSB).
• 2 m from any SSB radio transmitters.
• 2 m from the radar beam path.
After selecting the instrument position, follow the steps given below:
•
Fix the drilling template sheet onto the surface using adhesive tape.
• (Fig. 1) drill 4 holes for the bushes using a Ø 11.5 mm bit.
• (Fig. 2) prepare the central opening with a suitable tool following the indications on the template.
• Remove the template and any cutting burrs present at the holes.
WARNING: an inaccurate cut can compromise the tightness of the gasket between instrument and panel.
