Care and Maintenance
To get the best performance and longest service life possible out of your
icListen
, it is important to
properly care for and maintain your unit. Here are a few things which should be remembered when
using your
icListen
.
9.1
Firmware Updates
Occasionally, Ocean Sonics may provide firmware updates for
icListen
.
WARNING:
Applying firmware updates will cause all logged WAV, TXT and Epoch data to be erased from
the instrument.
Updates for
icListen AF
(Ethernet/SLIP Enabled) are applied using FTP, SCP or SFTP.
Ocean Sonics’
Lucy
software or any FTP client (such as FileZilla) may be used for this. When using SFTP or SCP, connect to
port 22, use “icListen” as the user name, and by default there is no password.
The update file will be
named icListenUpdateAF###.icu (with ### replaced by the release number of the update). Updates may
be applied either u
sing Ocean Sonics’ Lucy software, or a using an FTP client and web browser.
It is very important that
icListen
remains powered during the update process. Ideally the battery should
not be fully discharged during this process, to avoid the unit shutting down mid-update if the power is
interrupted. Shutting down
icListen
mid-update will leave the filesystem in an unknown state.
