The analogue tachograph on your vehicle becomes faulty. How long do you have before you must have it repaired?

Explanation: If the tachograph on your vehicle becomes faulty, you should take it to an approved tachograph repairer as soon as possible. If you can't return to your base within a week of finding the fault, it must be repaired while you're away. While the tachograph is faulty or broken, you must keep a manual record of your activities.
