The batteries or the BA 2015 accupack is going flat (LOW BATT).

In addition, the 4-step indication in the display tells how much power is left in the batteries or BA 2015 accupack:

3 bars	charge status approx. 100%
2 bars	charge status approx. 70%
1 bar	charge status approx. 30%
Battery symbol flashes	LOW BATT

The lock mode icon	appears on the display when

the lock mode is activated (see “Activating/ deactivating the lock mode” on page 40).

Modulation indication

The audio level (AF) display shows the wireless microphone modulation.

If the audio input level is too high, the audio level display (AF) shows full deflection for as long as overmodulation lasts. You can change modulation by changing the input sensitivity of the wireless microphone, as described on page 38.
