1.7 Basic Usage Notes
WARNING
Measurement port cover
The cover prevents dust and other contaminants collecting in the
measurement port. Keep this cover closed except when a cable is
connected.
Condensation
Condensation may occur in the Network Master when it is taken into a
warm room after use outdoors, etc. In this case, allow the Network
Master to dry out thoroughly before powering up.
Temperature range
Use the unit within the operating temperature range (0° to +40°C) and
store it within the storage temperature range (–20° to +60°C). If the unit
is left in a car or other enclosed space for a long time during summer, the
ambient temperature may exceed the specified range, resulting in
malfunction.
Safety
Only use the Anritsu AC Charger/Adapter or Ni-MH Battery Pack,
otherwise the unit may be damaged.
Laser
NEVER look directly into the Network Master optical connector or end of
a connected cable, otherwise laser light may enter the eye and cause
injury. In addition, some SFP modules output high-power optical signals.
To prevent damage to connected equipment, check that any connected
photo-receiver will not be saturated. Anritsu accepts no responsibility for
damage caused to connected communications devices.
Maintenance
Anritsu recommends annual inspections (charged) of the Network Master
by an Anritsu Customer Service Center.
For other usage notes, read the safety-related information in this manual
thoroughly before use.
