FIRMWARE UPGRADE
The embedded software in the ES3S (the firmware) can be updated (e.g., when
new features are added or maintenance releases are made available). Updated
firmware and the PC application required to install updates will be available from
distributors or may be downloaded from the Micro Audiometrics web site.
Firmware load is done via the ES3S USB interface. In order to install new
firmware, the ES3S must be placed in update mode by holding down the
{Menu}
key as the instrument is powered on by pressing the
{On}
key. Once the firmware
update is completed, the ES3S will return to normal operational mode.
Note: If the ES3S is inadvertently put into Update Mode, it will remain in
that mode until the firmware is updated or until the instrument power is
disrupted (e.g., by unplugging the wall cube and/or removing at least
one battery).
