• Calibrate: Choose your required frequency with the rotary knob.
• Test: Play the tone to one ear at an audible level (e.g., 40 dB). Use the attenuator knob; decrease in 5dB steps until the patient can no longer hear the tone, then increase to their threshold.
• Record: Indicate the threshold for that frequency on the audiogram form.
  Repeat: Repeat the steps for all necessary frequencies and the opposite ear to fill in the audiogram.282
