FREQUENCY SHIFT BKR BR-1420

Configuring:

1. This device is equipped with a powerful DSP system which will filter alarms. Actively protect and maintain the original signals.

2. Setting is not a mandatory procedure in everyday use. The device will adapt automatically to the acoustic medium (the process takes about 10 seconds) and the system will provide additional 6-12 dB.

3. When poor condition (equipment warns several times) if the sound quality is deteriorated please turn down the volume, and press the quick calibration after a few seconds hiss (6 dB), high quality sound will be restored.

4 tone adjustment potentiometer position allows working with different microphones in order to avoid interference to the greatest extent.
