• What do the red and green sectors on the dial mean?
These are the silence periods for maritime radiotelephony. During the red sectors (minutes 15–18 and 45–48) and the green sectors (minutes 0–3 and 30–33), emergency frequencies were kept clear for distress calls. This makes this clock recognizable as an authentic radio room clock.

• What battery does the clock require?
One AA battery (Mignon 1.5 V). This is not included.

• How do I replace the battery or set the time?
Take the clock off the wall or from the separate A130 mounting plate, replace the battery or adjust the time, and hang it back up.

• How accurate is the clock?
The quartz movement is accurate to approximately ±6 minutes per year. Setting it occasionally, for example when switching to summer or winter time, is sufficient.

• Can the clock be hung on board?
Yes. The housing is made of mirror-polished 18/10 stainless steel, and the front is mineral glass. Hang the clock inside in a dry place, such as the cabin, and not outside in wind and spray. If the boat remains in the water during winter, remove the battery to prevent leakage.

• Is there a warranty on the clock?
Yes, you receive a 2-year statutory warranty. This covers defects not caused by external influences or improper use, including issues with the operation and the movement.
