The intensity levels available vary with the frequency selected ipsilaterally as follows:
226 Hz Probe Tone
1000 Hz Probe Tone
NOTE:
1000 Hz is not available when using the 1000 Hz Probe Tone option.
NOTE:
Although four frequencies are available during the tymp and ipsilateral reflex test mode, most
situations require only one or two frequencies to be tested. A selection of the most commonly used
frequencies is available; however, it is strongly recommended that only one to two frequencies per
test are selected. Holding the probe in the same position for the length of time required to test four
frequencies may become uncomfortable for both the tester and individual being tested.

Only 80 and 90 dB HL are available on the Combo Probe.
TEMPORARY PROGRAMMING OF IPSILATERAL ACOUSTIC REFLEX TEST
FREQUENCIES
The instrument defaults to a 1000 Hz Ipsilateral test stimulus when the
TYMP REFLEX
button is first
pressed. Any combination of the four available frequencies (500, 1000, 2000, 4000 Hz) for 226 Hz
Probe Tone and three frequencies (500, 2000, 4000 Hz) for 1000 Hz Probe Tone can be selected either
temporarily or as revised default parameters. To temporarily modify the default condition:
1.
Press the
Tymp Reflex
button.
2.
Select the test
frequencies
by pressing the desired Frequency button (e.g.,
500 Hz
or
1000 HZ
).
Pressing the Frequency button a second time will deselect that frequency from the test
sequence. Test frequencies must be selected before the probe is in the ear. Each frequency
selected will be indicated on the display. For example, if 2000 Hz is selected along with 1000
Hz, the la
bel “I 1000” will a
ppear at the top of the first column of numbers for reflex an
d “I
20
00” will appear
directly below it. If 500 is also selected, the screen will be modified so that
“I 500”
appears at the top of the first column of reflex number
s, “I 1000” will appear directly
below “I 5
0
0” and “I
2000” will a
ppear at the top of the second column of reflex numbers and
directly to the r
ight of “I 500” and
so on.
To change the default setting, see the
Program Mode
section.
