6.1 Target Creation<br />
In order to create a target for use in the Coupler Target screen or the Coupler<br />
EarSim screen, you must enter the Audiogram Entry screen, just as you would if<br />
you were creating a normal real-ear target.<br />
1. Enter the Audiogram Entry screen by pressing [F2] from the Opening screen<br />
and using the [NEXT] and [BACK] keys if necessary.<br />
2. Follow the instructions found in Section 5.3 to enter the patient’s audiogram<br />
and to create a real-ear target.<br />
3. Follow the instructions found in Section 5.3.6, if desired, to measure the<br />
patient’s RECD.<br />
4. Press [EXIT] to return to the Opening screen.<br />
5. Press [F3] to enter one of the coupler multicurve screens. Use the [NEXT]<br />
and [BACK] keys to enter the Coupler Target screen or the Coupler EarSim<br />
screen.<br />
6. Press [MENU] and [BACK] to enter the Target menu. Set the FIT RULE, AGE,<br />
AID TYPE, VENT, and TUBING (if applicable) in this menu using the arrow<br />
keys. If you select NAL-NL1 or MOD NAL as your FIT RULE, you will also<br />
have to set COMPRESSION, CHANNELS, AID LIMITING, and FIT TYPE.<br />
See Section 5.3.4 for details.<br />
7. Press [EXIT] to return to the measurement screen. You are now ready to perform<br />
the measurements and compare them to the displayed target.<br />
The Coupler Target screen converts the real-ear target into a coupler target displayed<br />
in either dB GAIN or dB SPL. The Coupler EarSim screen displays realear<br />
targets in either dB IG (insertion gain) or dB SPL. When the Coupler EarSim<br />
display is set to dB SPL, the patient’s HTL and UCL values are also displayed.<br />
To switch between the gain and SPL displays in each screen, use the [MENU]<br />
key to open the local menu, and use the arrow keys to select GAIN or SPL in the<br />
DISPLAY field. [EXIT] will close the local menu.<br />
Targets are usually tied to the source type and source level of CRV 2. If you<br />
would like to tie the target to a different curve, or to the currently selected<br />
curve, change the TARGET REF setting in the Target menu. See Section 6.3.3.<br />
If you have modified the actual numerical target values in the Audiogram Entry<br />
screen, or entered your own target entirely, you will not be able to enter the
