Common Settings

The common settings screen offers setup of user preferences to the audiometer.

To enter the common settings screen, hold the setup button and use either attenuator wheel to highlight common settings.

Release the setup button to enter the settings screen.

Once inside this menu, use the right attenuator wheel to choose between the different options listed and the left attenuator wheel changes the individual settings for each selection.

There are different sections to the screen such as intensity, representation, pulse and so forth.

The first section to be reviewed is the intensity section.

Intensity

'Intensity steps' default the startup settings for the decibel step size.

Options include 1, 2 or 5 dB.

Once this is set and saved, this will be reflected on the dB button on the audiometer.

The default level when changing output can be set from off to 50 dB in 5 dB steps.

This sets the intensity level for channel 1 when changing the transducer during a test.

When off is selected, the decibel level will remain at the last setting before the transducer is changed.

'Channel two start intensity from off to on' allows the audiometer to have a preset level defined when channel 2 is turned on.

This setting is selected from minus 10 to 50.

'Channel two intensity when changing frequency' can be set from off to 10 dB.

When off is selected, the channel 2 intensity will remain where it was last left.

By choosing any other option, the channel 2 intensity will be set to that level: 0, 5 or 10.

Representation

Representation has three options for selection.

1. Show maximum intensities

This will be displayed by a darker shading on the audiogram.

When this is unchecked, this darker shading is removed.

Showing the maximum intensities is a good reminder to the examiner of the limits of the transducer.

There's a safety feature within the audiometer where the maximum intensity can be increased by selecting the extended range button.

For more information on the extended range button, review the keyboard button overview or the instruction for use manual.

2. Show masking cursor

This allows a visual cursor on the audiogram at the level where the masking is being introduced.

This is an addition to the intensity level at the top of the screen.

3. Default symbols

This allows you to select other symbol settings.

US symbols is the default setting.

Pulse

The pulse section allows changing the pulse length for the multi and single pulse presentation.

Default settings are 200 milliseconds for the multi pulse and 500 milliseconds for the single pulse lengths.

Startup

The startup section has one option: 'Ask for settings at startup'.

This allows for a user profile menu to immediately be available once the audiometer's been turned on and booted up.

This option is only necessary when multiple user profiles have been saved within the device.

Automatic output selection

Automatic output selection has three options.

1. Use insert masking for bone

This should not be checked.

This is a special insert masking transducer that is not a standard accessory with the device nor used in the United States.

2. Channel two opposite channel 1 output

This will allow the audiometer to automatically change the transducer of channel 2 when channel 1 is changed.

For example, if the examiner changes to the left phone in channel 1, channel 2 will be switched to the right.

It is important to note that if channel 2 is set to OFF, this will not switch the transducer until it has been turned on.

3. Use HF phone

The last option is use HF phone.

This selection defaults the high-frequency phones or HDA200 to the phone button on the audiometer.

This is a convenient setting when an examiner uses the high-frequency phones as the standard headphones throughout the testing process.

Once activated, the HF phone function key is highlighted yellow during the test session.

If you do not use HF phones, select the function key to override the setup of the session.

Once you save the session or reboot the audiometer, the HF phone setting will return to the setup configuration.

Standard

The standards section only allows you to change the filter mode.

The linear setting is recommended in the United States.

Hardware

The last section in common setup is hardware, which has seven options.

1. License key

The first option allows for upgrading a license.

This field is only modified when working directly with Interacoustics.

2. Display light

This allows you to modify the LCD screen to your preference.

3. LED light

The LED light is a light on the audiometer keyboard that you can dim.

4. Printer type and 5. Printing color mode

When a printer is connected to the hardware, you must modify the printer type and printer color mode for connectivity purposes.

Select the printer from the list as well as the printing color mode you prefer.

6. Output thresholds in single graph with HF

You must check this when printing from the hardware and to display the high-frequency results from 9 to 20 kHz.

7. Time

The time field allows you to set the date and time.

This is displayed when saving the client session and is included on the printout from the device.

Once within the field, use the attenuator wheel to cycle through the selections and press the tone switch to set the selection.

Other options

The bottom of the screen offers multiple function key selections.

These include 'Client', which allows a list of those saved clients that are within the audiometer.

The 'Install' function key is used to install firmware, Wave files or a logo for printout.

'Language' provides a list of languages for selection that converts all text within the LCD screen.

'Back' moves you out of this screen to return to the testing function of the audiometer.

Lastly, 'SaveAs allows you to save any changes made to the setup screen.

When the protocol is saved, you can save within a current user setting or create a new user setting.

When making changes to a setup screen, shut the device and turn it back on for changes to take place.
