Warning: Class 1 Laser
To prevent possible damage to your eyes caused by
hazardous radiation:
•
Do not look directly into optical connectors. Some optical
equipment emits invisible radiation that can cause
permanent damage to your eyes.
•
Do not turn on the meter unless a fiber is attached to the
port.
•
Do not use a magnifying device to look at the optical
outputs without the correct filter.
•
Use of controls, adjustments, or procedures that are not in
this manual can cause exposure to hazardous radiation.

Caution
To prevent damage to fiber connectors, to prevent data
loss, and to make sure that your test results are as accurate
as possible:
•
Do not connect APC connectors to the meter. An APC
connector will cause damage to the fiber endface in the
connector on the meter.
•
Use only patch cords that comply with GR-326-CORE
specifications. Other patch cords can cause unreliable
measurements.

•
Use the correct procedures to clean all fiber connectors
before each test. If you do not do this or if you use
incorrect procedures, you can get unreliable test results
and can cause permanent damage to the connectors.
™
•
Put protective caps on all connectors when you do not use
them.
•
Do not connect the meter to a network that is on. If you
do, the meter can cause problems in the network.
•
If ACTIVE LINE blinks, immediately disconnect the meter
from the fiber. Optical power levels more than +7 dBm can
cause damage to the detector in the meter.
