ELI 250/210__________________________________________________________________________

Cleaning and Inspecting Techniques

This section contains instructions for periodic cleaning and inspection of the instrument as preventative maintenance measures. It also contains specific cleaning procedures to be conducted after disassembly. Parts having identical cleaning procedures are grouped under common headings. No special tools are required.

Interior Cleaning

WARNING

Ventilate work area thoroughly when using solvents. Observe manufacturers warnings on solvent containers with regard to personnel safety and emergency first aid. Be sure that first aid equipment is available before using chemicals. Observe all shop safety and fire precautions.

Magnetic Cleaning

CAUTION

Do not use solvents to clean transformers or inductors. The chemical action of solvents may remove the varnish from the wire coils, rendering the components useless. The solvent also neutralizes the adhesive of the cover tape, resulting in eventual tape separation from the windings.

Clean transformers and inductors with a dry, non-metallic, soft bristle brush.

Printed Circuit Board Cleaning

The printed circuit board assemblies in the ELI 250/210 system contain static sensitive devices. Use special handling procedures to prevent damage due to ESD.

Clean assembled parts with a vacuum cleaner or low pressure compressed air (30 psi). Take care when cleaning printed circuit boards that wires or component leads are not bent back and forth in such a manner as to weaken them and cause them to eventually break.

Dry with low pressure compressed air.

2-2

____________________________________________________________________________Section 2

Metallic and Plastic Parts Cleaning

CAUTION

Do not wipe over surfaces of nameplates or labels with abrasive cleaners or materials, as this will eventually wear away the nameplate information. Do not use solvents to clean plastic parts.

Brush all surfaces and parts with a nonmetallic, soft bristle brush.

Wipe metal surfaces with soft, nonabrasive cloth dampened with isopropyl alcohol.

Dry surfaces with clean cloth.

Wipe surfaces of nameplates and labels with dry cloth.

Exterior Cleaning

Use a damp cloth to clean external covers and the line cord. Do not use alcohol, solvents, or cleaning solutions. These cleaning agents may damage the surfaces of the instrument.

Printhead Cleaning

Open the writer cover as explained in the section on final assembly.

Apply isopropyl alcohol to a clean cloth, and wipe the writer printhead until all foreign matter is removed. Dry the printhead thoroughly before use. Use a dry clean cloth for this.

After cleaning is completed, inspect the unit using the techniques described previously.

After the inspection is complete, install the cover as explained in the section on final assembly.

Inspection of Writer Assembly Harness

Visually inspect the wire harnesses for wear, maintenance damage, corrosion, deterioration, and damage resulting from dropping.

If no defects are found, install the cover and restore the unit to service.

If a defect is found in the cables, replace the damaged cable with a new cable.

Configuration Page 1

Software Version

The displayed number identifies the firmware version of your electrocardiograph.

Cart Number

Cart numbers indicate which electrocardiograph transmitted a particular ECG.

Site Number

This option identifies the site of your ELI 250. Site numbers designate the hospital, clinic, or institution for ECG records stored in a Mortara Instrument, E-Scribe data management system and must be defined for transmitting and retrieving ECGs from the data management system. You can use up to four digits for the site number, numbers from 0 –4095 are supported.

Site Name

This option defines your clinic, hospital, or office name. You can enter up to 30 alphanumeric characters. The site name prints at the bottom, left edge of the ECG printout.

Telephone Number

This option specifies the telephone number for modem transmission (to another unit or to an E-Scribe data management system). Enter up to 30 alphanumeric characters, and use the BACKSPACEÍ key to erase entry errors.

To wait for an additional dial tone, use the letter W. For example, you may need to dial a 9 to get an outside line.

EXAMPLE: 9W14145554321

To insert a pause use a comma (,).

To change tone dialing to pulse dialing, use the letter P.

EXAMPLE: P14145554321

3-8

____________________________________________________________________________Section 3

(If necessary, you can use both the letter W and the letter P in the same phone number.)

TIP: Instead of entering the configuration menus, use a shortcut to quickly delete or modify a phone number. From the application screen, simultaneously press Ï (SHIFT) + ALT + P. To edit an existing number, use the tab key.

Language

There are several languages available on the cardiograph.

CAUTION: upon selecting a new language and exiting the configuration screen, function labels are immediately translated.

If an unknown language is visible, use the following steps to revert to the language of your country:

1.F6 from Real-Time ECG View

2.Select number 3

3.Simultaneously press Ï (SHIFT) + ALT + C

4.Press F2 (▼) four times

5.Press F3 (►) until the desired language appears

6.F6 to return to Real-Time ECG View

Volume

This option defines the keyboard click loudness. Available settings rage from 0 (off) to 8 (loud).

TIP: Use the BACKSPACEÍ key to erase entry errors

Battery Timeout

This setting determines when the cardiograph will switch off in order to conserve the battery life of the unit. The battery timeout will only occur if the keypad has not been depressed for the time specified. The battery timeout setting is ignored if an active ECG signal is detected, during transmission, or while rhythm printing.

Flash Size

Flash Size indicates the ECG storage capacity of your electrocardiograph. Normal Flash Size is the standard memory capacity. If the optional expanded memory has been installed, Expanded will be displayed.

ID Format

This option defines the format for the patient ID information prompts. There are three standard formats: short, standard, or long. A custom ID format is optional when downloaded from the E-Scribe Data Management System.

The short format includes the patient's last name and first name, patient ID number, date of birth, which will automatically calculate the age, and gender field.

The standard format includes the patient's last name, patient ID number, age, height, weight, gender, race, medication 1, medication 2, and a location field.

The long format is identical to the standard format except that it includes the patient's first name, room and comment fields.

The custom format, which is designed in the Mortara E-Scribe Data Management System, can be downloaded to the ELI 250. The custom ID format is uniquely designed to meet your facility’s needs. Please see Appendix A to download a Custom ID.

AC Filter

The ELI 250 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that the proper AC filter is selected.

Paper Speed

The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm printouts and display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for display or rhythm printing.
