When the battery is low (less than 4 hours of autonomy remaining), the Pedestrian TAG alerts both audibly and visually:

• Audible: Beeps intermittently 5 times every 10 minutes
• Visual: Red LED flashes

Yes, but the vibration is standard and cannot be changed.

No. Both the sounds and vibrations (intermittent and continuous) are predefined and only work as described in the previous question.

ATTENTION Zone:
• Sound: Intermittent
• Vibrational: Intermittent
• Visual: Green LED blinks
DANGER Zone:
• Sound: Continuous
• Vibrational: Continuous
• Visual: Green LED blinks

There are three: sound alarm, vibrational alarm, or both together.
