Getting Started 1

•If you need to turn off the power, unplug the instrument at the mains or

remove the power cable connector from the appliance coupler at the

rear of the instrument. For this reason, the power cable connection

should be easily accessible - allowing you to turn off the power quickly.

If the instrument is in a cabinet, it must be disconnected from the line

power by the system’s line power switch.

•This instrument may be labeled with one of the safety symbols shown

below (if the instrument is not labeled with a certain safety label, the

respective safety measures do not apply to that instrument):

This label is located near certain parts of the instrument

that get hot during operation. This applies to the white

surface below the lid of the N7783B Thermal Cycling Unit,

i.e. the trench that the fiber is placed into. Avoid touching

this surface during operation.

This label denotes laser output ports of instruments that

contain laser sources. Refer to Table 1 on page -8 for

further details.

Initial Safety Information

The laser sources specified by this user guide are classified according

to IEC 60825-1 (2007).

The laser sources comply with 21 CFR 1040.10 except for deviations

pursuant to Laser Notice No. 50, dated 2006-June-24.

Table 1 Parameters of Lasers Included in certain instruments (see column headers for

respective product options)

•Under no circumstances look into the optical output of the instrument

or to an optical cable attached to the optical output when the device is

operational. The laser radiation can seriously damage your eyesight.

•Do not switch on the instrument when there is no termination to the

optical output connector, to the optical fiber or to the attached device.

•The use of optical instruments with this product will increase eye

hazard.

•Refer servicing only to qualified and authorized personnel.
