Store and display data
1. To store the results of the test, press the button which matches the tested ear, as
illustrated below.
The memory buttons are labeled for the right ear and for the left ear. When
test results are stored in memory, the RIGHT STORE or LEFT STORE message
appears momentarily on the LCD. Then the tympanogram which has been stored
reappears along with the right or left symbol (to indicate the contents of that
memory).
2. Press either the Left or Right memory button to recall the information stored in
memory. You may recall memory contents at any time.
Erase memory contents
You can erase memory contents in two ways:
• By storing a new test. The device automatically erases the previous test when you
store a new test.
• By pressing either the Left or Right memory button for more than three seconds. This
action erases memory contents for that ear.
Change the default frequency
The default frequency set at the factory is 226 Hz. However, if the majority of your
patients are infants less than six months old, you may set 1000 Hz as the default
frequency. Use the procedure below to switch from one frequency to another.
1. Allow the Handle to power down.
2. Unscrew the battery cover in a counter clockwise direction using the #1 Philips
screwdriver provided. Save the screw.
