• What do the red and green sectors on the dial mean?
These are the periods of radio silence used in 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 a genuine 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?
You rotate the clock out of its mounting ring on the wall, replace the battery or set the time, and rotate it back in. No tools are required for this.

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

• Can the clock be hung on board?
Yes. The casing is made of mirror-polished 18/10 stainless steel. Hang the clock inside in a dry place, such as the cabin, and not outside where it may be exposed to wind and spray. If the boat is left in the water over the 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.
