When data are entered from the keyboard, each character appears immediately in the display. It can be erased by back-
spacing, and corrected as necessary.
Press the keyboard ENTER key to terminate input, otherwise the Urisys 1100
system cannot start reading. Press the keyboard Escape key to delete the entire entry or turn the Urisys 1100 system off
and then on again.
6.7 Data Transmission to a PC or Host Computer
In unidirectional mode, the results are transmitted immediately together with the sequence number, Patient ID (if en-
tered), date and time.
In
bidirectional mode, transmission can only be accomplished by using the “Send” function when “MEMORY” is dis-
played. If a bidirectional PC/host communication link cannot be established, the Urisys 1100 system aborts transmission
after several attempts and reports an “INTERFACE ERROR !” (see Section 8).
In
ASTM
mode the results, sequence number, Operator ID, Device ID, Patient ID (if entered), date and time of the meas-
urement, and of the last calibration will be sent to the host.
For further information on the serial interface, refer to Section 9.1.

ATTENTION:
Ensure that all required data is backed up on a regular basis.
7. Cleaning and Maintenance
The Urisys 1100 system is designed for maintenance-free operation. Protect the instrument from extremes of temperature
and high atmospheric humidity (see Section 10), and keep it out of bright light (direct sunlight, spot lamps, etc.).
Maintain hygiene by keeping the exterior parts and surfaces of the instrument clean. For cleaning we recommend applying
a commercial cleaning agent or disinfectant (preferably 70 % alcohol) with a moist cloth. Take care that no liquid enters the
instrument.
7.1 Cleaning the Test Strip Tray
BIOHAZARD: Liquid waste and strip waste are potentially biologically hazardous. Always wear gloves if
handling those materials. Dispose of the used test strips according to the regulations for handling poten-
tially infectious material.
When inserting and removing test strips, take care that no urine residues come into contact with the retaining bar mecha-
nism.
To prevent carry-over and an accumulation of urinary deposit, wipe off residues of urine from the tray with a lint-free cloth
after each reading (see Figure 16).

At the end of each working day, clean the tray with water and, if necessary, with a commercial cleaning agent and disin-
fectant. The procedure is as follows:
1. Switch off the instrument.
2. Pull the tray out of the instrument.
3. Rinse the contaminated parts of the tray under running water, then clean with 70 % alcohol or another suitable disin-
fectant. Slight crystalline deposits, especially those contaminating the retaining bar mechanism or the cogs on the un-
derside of the test strip tray, may be removed with a soft brush. Dry the parts with a dry, lint-free cloth.

CAUTION: Take care not to damage the grey reference pad during cleaning, and ensure that it is
completely clean and dry before proceeding to read.
