2.1
Electrical Safety
z
Always use caution when handling live electrical connections.
z
Do not install electrical equipment in wet or damp conditions.
z
Ensure that the power source for the system is adequately rated to assure safe operation
and provides current overload protection.
z
Do not allow anything to rest on the power cable, and do not place this product where
people will stand or walk on the power cable.
z
To avoid electric shock of user which caused by over-voltage from PSTN, DO NOT connect
the POTS port on this unit directly to external PSTN line.
z
This unit can only be used with the certified adaptor model included inside the package,
which complies with the requirement of limited power source.
DANGER:
Do not open the enclosure without CIG’s permission and technical support, which
is dangerous and voids the warranty.

Laser Safety
CAUTION:
Use of controls or adjustments, or performance of procedures other than those
specified herein may result in hazardous laser radiation exposure.
Invisible laser radiation may be emitted from the ends of un-terminated fiber cables or
connectors. Never look directly into an un-terminated cable or connector.
This ONT uses a class I laser device.
DANGER:
Personnel handling fiber optic cables must be trained for laser safety.
CAUTION:
Do not bend the fiber optic cable to a diameter smaller than 7.5 cm/3 inches.
Doing so may damage the fiber or prevent the signal from passing through properly.

Environmental Requirements
The ONT will operate in temperatures ranging from 0° C to 40° C, relatively humidity ranging
from 0° C to 85° C.
3.1.2
Power Requirements
The ONT will be shipped with a universal power adaptor. However, before installation, check if
the AC power input matches the specification printed on the power adaptor (input voltage,
current, etc.)
CAUTION:
Please use the power adaptor within the package only, or the replacement unit
that provided by CIG. Other power adaptor may cause damage to the ONT and other
disasters.
