Troubleshooting
If a system error message appears on the screen during
operation and you cannot resolve the problem, contact
Advanced Instrument Technical Service for assistance
(see
Contacting Advanced Instruments
).
For quickest results, have the model and serial number
from the bottom of the instrument available when you
speak to a technician.
If you need to send your OsmoTECH XT for servicing, a
technical service representative will provide you with an
RMA number. Units are not accepted for service without
an RMA number.
CAUTION:
Do not open or remove the instrument
covers unless you are advised to do so by a service
engineer.
If you are advised to open or remove the
instrument covers, always unplug the power cord first.
You could be exposed to electric shock, excessive
temperatures, or mechanical hazards
