For Safety

For safety, do not open the equipment covers.

If repair is required, contact the sales representative, branch office, or agent at the

telephone number and address given in this document or in the equipment opera-

tion manual.

Although not recommended by Anritsu Corporation, if it is really imperative to

open the covers for emergency repair, take great care not to touch any dangerous

parts. Always request repair by a trained engineer who understands the hazards.

Anritsu Corporation will not accept liability for any injuries sustained as a result of

the equipment or supplied for repair. This is because equivalent

parts with the same functions, performance and reliability as the

parts specified in the circuit diagrams and parts list have been used

or supplied. Since the parts are equivalent, they have absolutely no

adverse effect on the equipment specified functions, performance or

reliability.

Laser Radiation Markings

For Safety

WARNING

Class 1 Safe laser presenting no danger when used according to

design specifications.

Class 2 Laser radiating in 400 to 700 nm wavelength range. In

principal, this class of laser is not safe, but the danger to

the eyes is eliminated by the eye avoidance reaction in-

cluding the blink response.

Class 3A Laser radiating in 400 to 700 nm wavelength range. The

danger to the eyes is eliminated by the eye avoidance

reaction including the blink response. For lasers radiat-

ing at other wavelengths, the degree of danger to the na-

ked eyes is not greater than Class 1.

Class 3B The eyes will be damaged if direct laser radiation enters

the eyes. Normally there is no danger if the diffused

beam is observed.

CAUTION

Use of Controls or adjustments or performance of procedures other

than those specified herein may result in hazardous radiation expo-

sure.
