Use Of Hazard Information; Precautionary Labels; Certification - Hach SC4500 Instructions D'utilisation

2.1.1 Use of hazard information

Indicates a potentially or imminently hazardous situation which, if not avoided, will result in death or
serious injury.
Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death
or serious injury.
Indicates a potentially hazardous situation that may result in minor or moderate injury.
Indicates a situation which, if not avoided, may cause damage to the instrument. Information that
requires special emphasis.

2.1.2 Precautionary labels

Read all labels and tags attached to the instrument. Personal injury or damage to the instrument
could occur if not observed. A symbol on the instrument is referenced in the manual with a
precautionary statement.
This symbol, if noted on the instrument, references the instruction manual for operation
and/or safety information.
This symbol indicates that a risk of electrical shock and/or electrocution exists.
This symbol indicates the presence of devices sensitive to Electro-static Discharge (ESD)
and indicates that care must be taken to prevent damage with the equipment.
Electrical equipment marked with this symbol may not be disposed of in European
domestic or public disposal systems. Return old or end-of-life equipment to the
manufacturer for disposal at no charge to the user.

2.1.3 Certification

Pacemaker precautions. If electromagnetic interference (EMI) occurs, it can either:
• Stop the stimulating pulses from the pacemaker that control the rhythm of the heart.
• Cause the pacemaker to supply the pulses irregularly.
• Cause the pacemaker to ignore the rhythm of the heart and supply pulses at a set
interval.
Current research shows that cellular devices are not a significant health problem for most
pacemakers wearers. However, persons with pacemakers should use precautions to
make sure that their device does not cause a problem. Keep the device a minimum of
20 cm (7.9 in.) from the user.
