Error Codes
ERROR1 → RF frequency lock circuit fault.
ERROR3 → During ACT sync ∼ the frequency bands between transmitter and receiver are different and not compatible. Press the MODE button or reset by power off.
ERROR4 → During ACT sync ∼ the frequency bands between transmitter and receiver are different and not compatible. Press the MODE button or reset by power off.

Cautions

Avoid using the same frequency bands when MIPRO IEM and wireless microphone systems are utilized at the same installation.
Using different impedance earphones, different battery types, high monitoring volume, cold/high temperature and higher gain settings may cause the receiver battery life to be different than specified. Earphones with sensitivity over 110dB/mW are recommended.
Remove the batteries when is not used for a long time and to prevent damaging to the electronics due to battery leak.

Note

Refer to actual product in the event of product discrepancy.
Frequency range and maximum deviation comply with the regulations of different countries.
