Password reset for Digital Instruments, Digitisers and Acquisition Systems

These reset procedures should be used if your password has been forgotten.

It is not, in general, possible to recover a forgotten password. The procedures below can only be used to reset the password to the factory default. The password should then be changed immediately. Güralp recommend the use of a random password generator such as that at random.org to generate truly strong passwords.
The default passwords of Güralp equipment are widely known. Do not connect any unit to the Internet without first changing the default password to something stronger. Strong passwords are essential for Internet-connected systems.

If the procedure linked here is not able to reset the password on your unit, please contact for assistance.
