or scuffed, contact the customer service for replacement.
NOTE: Do not use any material that will scratch the feed table insert or the white plastic
calibration chip. Do not use solvents of any kind to clean the calibration chip.
4. Wipe the feed table surface and feed table mounting groove with a damp cloth. Wipe the feed
table dry with an absorbent tissue.
NOTE: Residual water or solution on the feed table or feed table insert will cause
damage to the electronic components inside the instrument.
5. To replace the feed table insert in the feed table:
Hold the feed table insert in the same manner as when it was removed( holding it by the end
opposite the calibration chip ). With the front end angled upwards, insert the calibration chip
end about midway onto the feed table. Slide the insert in while lowering the front end until the
insert is laying flat against the table and resistance is felt. Then place the thumb against the
front edge of the insert and two fingers against the underside of the feed table. Apply a
counter-pressure to the feed table while pressing the insert firmly inward. The insert is
properly positioned in the feed table when the front edge is flush with the retain rails of the
feed table.
6. After replacing the feed table insert, the LEDs must be recalibrated. To ensure this occurs,
turn the instrument off, wait several seconds, and then turn it on again before testing
additional samples.
7.3 Disinfection
The only part of the UA-66 instrument that comes into contact with the urine specimen is the
feed table insert. To disinfection the insert, perform the followings:
1. Remove, clean and dry the feed table insert as instructed in 7.2.
2. Prepare one of the following solutions for use in disinfection:
a. 2% glutaraldehyde solution - Cidex
P
TM
(use full strength) is a commercially available
product that is acceptable for use. Refer to the labeling accompanying this disinfection
product for complete instructions on its use.
b. 0.05% sodium hypochlorite solution – dilute 1 mL of 5% sodium hypochlorite (e.g.,
Clorox® Bleach) into 99 mL of water for a 1:100 dilution.
c. Isopropyl alcohol (70% - 85%), undiluted.
3. Fill a tall, narrow container to a depth of 4 inches (10 cm) with the disinfection solution.
4. Immerse the feed table insert into the disinfection solution. So the white plastic calibration
chip must be above the liquid level.
NOTE: Do not allow the disinfection solution to come into contact with the white
plastic calibration chip, located on the feed table insert, or with any other portion of the
feed table or instrument.
5. Allow the feed table insert remain in the solution for 10 minutes.
