How to use the audiometer
With AC-powered
Plug the headphones into jack connector “12”.
Plug the patient feedback lead into “13” (accessory as an option).
Connect the power adapter into “14”.
Plug as well the power adapter into the mains power socket.
Press”1” - the green indicator light “2” comes on. The display screens “4” and “7”
will briefly show type of device and the version of the embedded software, and then
display screen “7” will read “1000 Hz” while display screen “4” will read “0 dB”.
Use keys “8” and “9” to set the frequency.
Use keys “5” and “6” to set the hearing level (when the audiometer reaches 100 dB,
the display indicates “! +100 dB” to alert the fact that a high sound output could
cause patient discomfort).
Select the operating mode by pressing key"3". When the pulse mode is selected, a
symbol such as
appears on the frequency display.
Use keys “10” and “11” to deliver the tone to the patient.
Press “1” to switch the device off.
With the battery option
Plug the headphones into jack connector “12”.
Plug the patient feedback lead into “13” (accessory as an option).
Press “1” to switch the device on. The display screens “4” and “7” will briefly show
type of device and the version of the embedded software, and then display screen
“7” will read “1000 Hz” while display screen “4” will read “0 dB”. If the battery is
undercharged, display screens “4” and “7” will blink, displaying “Battery” when
attempting to press a key. The device is still operational, but at this point it should
be connected to the mains power via “14” to power the audiometer and charge up
the battery. The indicator light “2” comes on to signal only when the power adapter
is plugged into the mains. It lights up orange while the battery is charging and
green when the battery is fully charged. The battery can be charged up without
pressing “1”. If the batteries have discharged too much, the audiometer will not
have enough power to run and will have to be connected to the mains power source.
From here on, the audiometer runs in exactly the same way as when this one is AC-
powered.
