Introduction
Laser Safety Information for Optional Optical Transceivers
The FrameScope Pro is a powerful handheld instrument that
measures the performance of your key network resources and
troubleshoots the active network equipment.
The FrameScope Pro allows the performance of Voice over IP
(VoIP), IPTV, and DSL network resources to be verified. The
FrameScope Pro also integrates network performance analyzer
features such as Auto Discovery, network performance testing,
traffic generator, and fault finding with wiremap testing
feature.
The laser sources specified by this user’s guide are classified
according to the IEC 60825-1 (2001).
The laser sources comply with 21 CFR 1040.10 except for
deviations pursuant to Laser Notice No. 50, dated 2001-July-26.

AC power supply requirements
The provided AC adapter accepts an input voltage between 90 V
and 240 V with a line frequency between 50 Hz to
60 Hz ± 5%. The AC adapter provides an output of 12 VDC, 1.5 A
with a ferrite core clamp.
Line power cable
The type of power cable shipped with each FrameScope Pro
depends on the country of destination.
To avoid the possibility of injury or death, you must observe the following
precautions before switching on the FrameScope Pro.
• If the FrameScope Pro is to be powered via a step-down transformer,
ensure that the common terminal connects to the earth pole of the
power source.
• Only insert the power cable plug into a socket outlet with a protective
earth contact. Do not use an extension cord without a protective
conductor.
