Note: If the tactile option is installed with the Colt audiometer, the frequency knob can only set
both channels to one frequency. Use the tablet sliders to set different frequencies.
SISI:
Touch the REVERSE tab for the test channel. Leave the stimulus in the other channel off. Touch
the PULSE tab to enable the action. Adjust the level, frequency and desired dB resolution (1, 2
or 5, see section 3.1.7 ) as needed.
A test stimulus is generated at a level higher than the steady state tone as set by the dB tab in a
short pulse every 5 seconds.
DLI :
Touch the REVERSE tab for the test channel. Leave the stimulus in the other channel off. Touch
the PULSE tab to enable the action. Adjust the level, frequency and the desired dB resolution
(1, 2 or 5, see section 3.1.7 ) as needed.
A test stimulus is generated at a level higher than the steady state tone as set by the dB tab
alternating at 250 milliseconds on and off.
This option is somewhat similar to SISI.
