To Perform Tympanometry: 

The system defaults to the right ear in the adult test mode with a constant pressure speed throughout the test using a 226 Hz probe tone. To perform tympanometry:

• press TYMPANOMTERY icon
• press START
• during testing, the START button turns to a yellow STOP button
• when testing is complete, the yellow STOP button turns back to a green START button

How do I change testing parameters for tympanometry?

The tympanometry display screen is shows below.  The left portion of the screen shows an RED highlighted box. Above the box is a RED horizontal header with the letter "R" in the far left hand side, indicating "Right Ear". The system defaults to the right ear.  To change ears, touch the general area of the red highlighted box.  The display will now show a tympanogram graph with a BLUE highlighted box and a BLUE horizontal header. The right portion of the blue header will show "L" for "Left Ear". 

The display screen also features several touch buttons for changing various parameters as follows:

1: Mode button (adult or children): icon above indicates "Children function".  When performing tympanometry, this option distracts child by showing animations on the display during testing. 

2: Single vs Three Sequence button: Single option (designated with 1) performs one tympanogram; three sequence option (designated by 3) performs three tympanograms in sequence with ability for provider to select the one to be saved in database. 

3:Pressure Range button:  default setting =200/-400 daPa; other option is +100/-200 daPa.

4: Probe Tone button: default 226 Hz; other option is 1000 Hz.

5: Pressure Variation Rate button: AUTO introduces pressure at max speed and then reduces when approaching peak compliance (to improve definition). FAST option generates pressure variation rate constantly at the max speech throughout the entire test. 

6: Start button:  pressing this button starts the tympanometry procedure

To Perform Acoustic Reflex Testing: 

To perform tympanometry:

• press REFLEX icon
• press START
• during testing, the START button turns to a yellow STOP button; the system automatically performs acoustic reflex testing for selected frequencies using established parameters
• when testing is complete, the yellow STOP button turns back to a green START button

The SETUP icon may be used to select/deselect test frequencies, set start and stop intensity levels (50-100 dB HL range), and increment levels (5 or 10 dB HL). 

To Perform Rapid Screening: 

This feature performs tympanometry and a reflex testing sequentially, eliminating the need to perform tympanometry and reflexes separately. The user can define which frequencies to include in reflex testing, and the unit offers the ability to save up to 3 test parameters

• press QUICK icon
• during testing, the START button turns to a yellow STOP button; the system performs tympanometry and immediately transitions to acoustic reflex testing for selected frequencies using established parameters
• when testing is complete, the yellow STOP button turns back to a green START button

How is the r16m powered?

The unit can operate on its own internal rechargeable battery (Li-Ion), or connected to a standard power cord (included) that plugs into a wall outlet, or when placed on the charging cradle. 

How do I turn the r16m on?

Briefly press the main switch located at the top left side of the unit.  To switch the device off, press the same button for about 2 seconds and then release.  

What is the PIN code for my device and why do I need one?

The standard PIN code is 1 2 3 4.  When turning the device on for the first time, enter the standard PIN code to unlock the device.  Once unlocked, the PIN can be changed.  Resonance updated the user interface to comply with European regulations and to protect patient data. 

How do I change the PIN code for my device?

• press SETUP
• press CHANGE PIN icon
• follow the instructions

How do I exit out of the CHILDREN tympanometry mode? The display keeps showing an animation and I can't get back to the main menu.

Press and hold the arrow button in the upper left hand corner of the screen. 

What is the PUK code for my device and why do I need one?

The PUK code is a second code for unlocking the device in case the wrong PIN code is entered after three attempts. Entering the wrong PIN code three times will lock the device.  The PUK code will be needed to unlock the unit. 

Where do I find the PIN and PUK codes for my device?

The PIN and PUK codes for your device appear at the bottom portion of the Pin and Puk document packaged with the unit (it should reside in a plastic bag containing the USB pen drive and stylus pen).  The standard PIN code is 1 2 3 4 which can be changed to a custom code.  The PUK code is unique to the device.  The PIN and PUK document should be filed for future reference in the event the wrong PIN is entered three time, locking the device, and to quickly access the serial number of the device. 

Where is the serial number of the unit?

The serial number of the r16m is located in several different places.  The serial number may be found on the bottom of the r16m.  It is listed on the PIN and PUK document included in product packaging.  In addition, the USB thumb drive packaged with the unit contains a file listing the serial number of the r16m unit.   

How do I perform tympanometry? 

Press the TYMPAOMETRY button on the main page.  To start the exam, ,press the green START button

How do I change from right to left ear? 

When selecting TYMPANOMETRY, a tympanogram graph with a RED highlighted box and RED horizontal header will appear.  The letter "R" will appear on the far left of the red header indicating right ear.  The system defaults to the right ear.  To change ears, press the red tympanogram graph. The display will now show a tympanogram graph with a BLUE highlighted box and a BLUE horizontal header. The right portion of the blue header will show "L" for left.   

How do I select the probe tone frequency for tympanometry?  

By default, the unit is set to perform tympanometry using a 226 Hz probe tone. Press the 226 Hz icon to switch to 1000 Hz probe tone.   

What is the purposes of the button in the top right corner that has an image of a tympanogram with the number 1 (or the number 3) underneath it?

Two test options are available:  one single tympanogram (designated with the number 1), or three in a sequence (designated with the number 3).  If you choose number 1, pressing start will result in the unit performing one tympanogram.  If you select three, three consecutive tympanomgrams are performed, providing you with the option to select the one to be saved in the database. 

What is the AUTO versus FAST pressure variation rate? 

The generation of the pressure variation rate (expressed in daPa/sec) into the ear can be set to two modes.  AUTO generates the pressure variation rate at the maximum speed, then reduced when approaching the peak compliance to improve its definition.  FAST generates the pressure variation rate constantly at maximum speed throughout the entire tympanometric test.

Can I change the start and stop pressure range for tympanometry?  

The unit provides two options.  The default setting of the unit is +200/-400 daPA.  Alternatively, ,+100/-200 daPa is the other option.

Things to Know Before you Buy

Three different versions of the r16m are available; make the most informed decision by reading this

Three versions include r16m-LITE, r16m, and r16m-D. All three versions offer 226 Hz and 1000 Hz probe tone.  All three versions offer ipsilateral acoustic reflex capabilities at 0.5, 1, 2 and 4 kHz. The main differences involve contralateral acoustic reflex capabilities, acoustic reflex decay capabilities, Eustachian Tube Function (ETF) test features as follows:

In addition, the r16m and r16m-D versions can be upgraded with OAE software modules whereas the r16m-LITE can not be upgraded.  

The r16m may be upgraded with available OAE software modules

If you are anticipating the future need, considering, or in need of a tympanometer with DPOE capabilities, r16m is a viable choice.
