1.  InPUt VOlUME COntROllER

It is a controller to control the volume of InpUT 1 - 6. Use by controlling to desired volume.

Set the controllers of unused input terminals to minimum.

2. InPUt SIgnAl InDICAtOR

If there is an input signal to InpUT 1 - 6, due input signal indicator lights up.

3. tOnE COntROllER

It is a controller to control BASS (100Hz) and TreBle (10kHz). Users can control to their desired tones.

4. MAIn VOlUME COntROllER

turning clockwise, the volume increases.

5. ChIME SWItCh

It is a switch to sound 4-note scale of chime. While chiming, a chime indicator on the left side of the switch
lights up.

6. OUtPUt lEVEl InDICAtOR

It  is  an  indicator  to  indicate  the  level  of  the  signal  being  printed.  Output  level  is  indicated  with  3  -  4dB
interval.

7. SIREn On/OFF SWItCh
