11.2 Cleaning the test strip tray
Keep the test strip tray clean and free of obstructions. Pay particular attention to
the reference pad (1) and the see-through LED window (2).
Always wear protective gloves when handling the test strip tray. See “2.4
Safety information” for further details.
Complete the following steps to clean the test strip
tray at least once a day:
1. Switch off the device and remove the test strip
tray by gently pulling it free from its slot.
2. Rinse the parts that can come into contact with
urine under running water. Wipe the tray with a
disposable towel dipped in 70 % (V/V) isopropyl
alcohol.
Take care not to scratch the white reference
pad.
3. Dry the test strip tray with a lint-free wipe.
Make sure that the test strip tray is complete-
ly dry before reinserting it.
4. Reinsert the test strip tray. See “4.5 Setup”.
11.3 Cleaning the printer roller
The printer roller can pick up grease and dirt that
can cause non-printing white spots or streaks on the
printout. It is recommended to clean the printer roller
at least every six months of device operation.
1. Switch off the device and press the printer cover
button to expose the printer roller.
2. Hold a lint-free wipe dipped in distilled water to the surface of the roller and
use the roller’s cog wheel on its left end to turn it. Make sure to wipe every part
of the roller surface.
11.4 The reference pad
The white reference pad on the test strip tray behind the test strip channel should
not get soiled or discolored during normal operation. Nevertheless, it is recom-
mended to check that it is intact whenever during cleaning the test strip tray.
If it is soiled or discolored, gently wipe it clean with a disposable towel dipped
in distilled water. Replace the reference pad if there are irremovable marks or
scratches on its surface. If the device is routinealy operated at or close to peak
throughput, the reference pad may need more frequent replacement.
