1.2.3 Maintenance Checks
1. With the system powered off, verify that all components and subsystems are properly
secured and that all cables are properly connected.
2. Verify the mandatory system modifications have been completed.
3. Verify the air filter is clean (clean it if necessary).
1.2.4 Functional System Test
1. Power on the system and verify the boot sequence completes without displaying an er-
ror message.
2. Perform the POST test and verify no errors occur.
3. Check the control panel function; press each key and verify the corresponding function
occurs.
4. Check the image and graphic overlay displayed on the monitor and verify they are con-
sistent with the transducer and user preset selections.
5. Check the system time and date, and reset as necessary.
6. Check the CD-RW drive functionality; check all operator controls and indicators, includ-
ing the foot switch (if installed), and the keyboard.
7. Always check the transducers, even when the transducers are not cover by a mainte-
nance contract. Replacement depends upon the type of maintenance contract.
- For each transducer, verify the transducer identification and operating frequency are
correctly displayed when the transducer is connected.
8. Perform a phantom scan with each transducer and evaluate the image quality.
- While scanning, flex the cable at the strain relief and verify that the image quality is
not affected.
- Check array transducers for signs of dropout (dark columns emanating into the im-
age).
1.2.5 Peripheral Device Check
Always check Siemens-approved peripheral devices (OEMs), even if the customer has not
signed a maintenance contract for them. The check includes cleaning and optimization of
settings if necessary. Replacement depends upon the type of maintenance contract. For
information about operating and cleaning of OEM peripheral devices, refer to the respec-
tive OEM operating instructions.
