14.1 Forgotten password
Passwords can be changed by the systems administrator(s) and by users with the acti-
vated right Edit User (see section "Edit user" p. 88). If the administrator Admin has for-
gotten the password and no one else has the right Edit user use the function Factory
settings (see section "Factory settings" p. 83) to reset the system and load a backup file
(see section "Backup" p. 98) to restore it.
14.2 Slow heating and cooling
The Biometra TRIO is equipped with a strong ventilator for the cooling of the heat sink.
The inlet of this fan is located at the bottom side of the instrument. Make sure the inlet
is not clogged by dust or other material (e.g. a sheet of paper placed under the cycler
can be attached to the inlet as the fan is in operation). Dust can be removed easily from
the inlet using a conventional vacuum cleaner.
14.3 Auto restart
The Biometra TRIO Thermal Cycler features an automatic restart. If a power failure oc-
curs during the run the instrument will continue the run when the power returns. In case
of long- term power failure (longer than 30 minutes) the instrument the instrument
keeps the sample block at 4°C (freeze step) and the user can decide to repeat the run
with the same samples or to discard them.
Note: After power failure the user has to log in again. In addition for a limited time in-
formation can be displayed.
14.4 Auto restart due to unrecognized power failure
High voltage fluctuation can lead to an automatic restart of the Thermal Cycler. In this
case the cycler restarts at the step where there power failure has occurred. A message is
displayed showing (a) that a power failure occurred during the run and (b) when and at
which step the program was started again. To avoid voltage fluctuation, do not connect
the cycler to a socket shared by a strong power consumer like a refrigerator or a centri-
fuge.
Note: After power failure the user has to log in again. In addition for a limited time in-
formation can be displayed.
