Precautions
• Always use two or more AN-820A units in pairs, installing each
pair of units at least 1 m (3 feet) apart.
• Make sure the units installed are visible from where the
wireless microphone or transmitter is used.
• Avoid installing the units:
- near a window or metal paneling
- immediately adjacent to electrical equipment, which may
produce RF interference
- where they are vulnerable to physical damage.
