• ON-OFF key: turns on and off the instrument. When you turn the instrument on, the display will switch on about three seconds later
• SETUP key: allows you to enter and scroll menu. To exit, press it repeatedly until you go back to the standard screen
• Display. When you turn the instrument on, it shows all segments on, and then the sound pressure level (94 or 114dB) will appear in standard view
• Calibrator cavity for conventional 1/2 inch microphones
• “Down” key: in standard mode, it selects 94dB and 114dB pressure levels alternatively. In menu mode, it decreases the current value
• “Up” key: in standard mode, it selects 94dB and 114dB pressure levels alternatively. In menu mode, it increases the current value
