Information Sources

In a crisis, reliable information is vital. When is it safe to leave the house? Where should you evacuate? Is the tap water still safe? These questions are answered by radio even when the internet and mobile networks are down. Authorities use radio as the primary channel for emergency notifications — you should be prepared to receive them.

Physical maps and a compass complement digital navigation in situations where GPS signal or mobile coverage is unavailable. The combination of a crank radio, battery radio, map, and compass keeps you informed and capable of action in almost any emergency situation.

Radio & Reception

• Crank RadioEssential

  A crank radio is the most important information device for emergencies. It operates completely independently from power or batteries — the built-in dynamo charges the internal battery by hand crank. One minute of cranking provides approximately 30-60 minutes of reception. Choose a model with AM, FM, and ideally DAB+ as well as a weather alert channel. In a disaster, official emergency radio stations provide critical up-to-the-minute guidance. Find out in advance which frequencies authorities in your region use for emergency communication.

• Battery-Powered RadioEssential

  A battery-powered radio is the most reliable option for extended, uninterrupted reception without cranking. Unlike a crank radio, it allows hours of comfortable operation on a shelf or table. Choose a model that uses standard AA or AAA batteries, which are easy to source. A radio with a telescoping antenna typically receives better than integrated antennas. Always keep a fresh set of spare batteries available and store the radio in your emergency backpack.

Navigation & Orientation

• Physical MapsRecommended

  Physical maps are the navigation medium that works without power, internet, or GPS. In an emergency it may be necessary to avoid familiar routes and take detours through unfamiliar terrain — a topographic map gives you the overview that no smartphone app can fully replace in offline mode. Include current maps of your region (1:50,000 scale), your city, and neighbouring districts. Mark important locations in advance: hospital, fire station, evacuation points. Laminated maps handle rain and moisture better.

• CompassRecommended

  A compass allows reliable direction finding without power or signal. Combined with a physical map, you can determine your position and navigate safely. Liquid-filled compass needles stabilise faster and are more shock-resistant. Practice map reading with a compass beforehand — it is easier than it sounds but requires some practice. Keep the compass away from metal and electronic devices, as these can deflect the needle.
