CAUTIONS:

Electrostatic discharge (ESD), or static shock, is a naturally occurring

phenomenon. ESD is common in conditions of low humidity, which can be

caused by heating or air conditioning. Static shock is a discharge of the

electrical energy from a charged body to a lesser or non-charged body. The

degree of discharge can be significant enough to cause damage to a transducer

or an ultrasound system. The following precautions can help reduce ESD: anti-

static spray on carpets, anti-static spray on linoleum, and anti-static mats.

Excessive bending or twisting of cables can cause a failure or intermittent

operation.

2.2 Equipment Protection

To protect your ultrasound system, transducer, and accessories, follow these

precautions.

CAUTIONS:

Excessive bending or twisting of cables can cause a failure or intermittent

operation.

Improper cleaning or disinfecting of any part of the system can cause

permanent damage.

Do not handle PCBs without proper static protection. Damage to components

may result from improper handling.

Do not use any of the ultrasound system connectors to operate accessories or

peripherals, when the ultrasound system is in the SiteStand mobile docking

station.This may cause damage to the equipment. This does not apply to the

ECG cable. The ECG cable must always use the dedicated I/O connector on

the ultrasound system.
