The following table shows the recommended maintenance procedures for the S2, patient accessories, and Li-Ion Battery 
Charger. The S2 should be serviced once a year by a Mortara authorized service technician; however, it is good practice 
to periodically ensure the telemetry device is in proper working order. This can be performed by a clinician or biomed 
at the hospital or healthcare delivery organization familiar with the S2 telemetry device, ECG signal acquisition, as well 
as general maintenance/calibration of biomedical equipment. 

 

To accomplish these steps in their entirety and verify the correct operation of the system, appropriate patient simulators 
or other equipment may be required.   Refer to the service manual for further details. 

 

Mechanical Integrity 

Check for cracks, abrasive edges and other signs of damage. 

ECG Telemetry 

 

Connect ECG leads to Patient Simulator. 

 

Start a new monitoring session. 

 

Verify that waveforms for all leads are properly shown on the LCD. 

Li-Ion Battery Charger

Check for cracks, abrasive edges and other signs of damage. 

 

Check that all connectors and AC cord length is unbroken and smooth along its 
length. 

 

Verify proper LED indicators during battery charging. 

ECG Cables 

 

Enzymatic detergent such as ENZOL (US) or CIDEZYME (outside the US). 

 

Distilled water. 

 

Disinfectant solution (such as CIDEX OPA, or a 10% solution of household 
bleach (5.25% sodium hypochlorite) in distilled water). 

 

Soft, lint-free cloths and/or soft-bristled brushes. 

 

Protective gloves and eyewear. 

 

1.  Remove the battery from the telemetry device.

it can cause corrosion. 

5.  Wipe smooth surfaces with the cloth. 
6.  Use a soft-bristle brush on visibly soiled areas and irregular surfaces. 
7.  Remove detergent from product using cloth dampened in distilled water.
