NOTICE

Data loss or damage to the system due to voltage drop

By a power failure or momentary voltage drop the operation unit or software of this system

may get damaged or data loss may occur. Use only uninterruptible power supply.

WARNING

Malfunction of analyzer and incorrect results due to interfering electromagnetic

fields

Devices that emit electromagnetic waves may cause the instrument analyzer to malfunc-

tion. Do not use this device in close proximity to sources of strong electromagnetic radia-

tion (for example, mobile phone, transceiver, cordless phone) as these can interfere with

the proper operation.

Class B FCC rule compliance

This equipment has been tested and found to comply with the limits for Class B digital

device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reason-

able protection against harmful interferences when the equipment is operated in a resi-

dential area. However, this equipment generates, uses, and can radiate radio frequency

energy and, if not installed and used in accordance with the present manual, may cause

harmful interference to radio communications.

The electromagnetic environment should be evaluated prior to operation of the device.

Class B International rules

Class B equipment is suitable for use in domestic establishments and in establishments

directly connected to a low voltage power supply network which supplies buildings used

for domestic purposes (CISPR 11, 4.2).

WARNING
