Safety Precautions
• Toxic materials which upon contact or inhalation, could result in injury, impairment of
health, or death.
Confined spaces are not designed for human occupancy. They have restricted entry and
contain known or potential hazards.
Examples of confined spaces include manholes, stacks, pipes, vats, switch vaults, and
other similar locations.
Standard safety procedures must always be followed prior to entry into confined spaces
and/or locations where hazardous gases, vapors, mists, dusts, or fibers may be present.
Before entering any confined space check with your employer for procedures related to
confined space entry.
1.4 FCC Requirements
1. The Federal Communications Commission (FCC) has established Rules which permit
this device to be directly connected to the telephone network. Standardized jacks are
used for these connections. This equipment should not be used on party lines or coin
lines.
2. If this device is malfunctioning, it may also be causing harm to the telephone network;
this device should be disconnected until the source of the problem can be determined
and until repair has been made. If this is not done, the telephone company may
temporarily disconnect service.
3. The telephone company may make changes in its technical operations and
procedures; if such changes affect the compatibility or use of this device, the
telephone company is required to give adequate notice of the changes.
4. If the telephone company requests information on what equipment is connected to
their lines, inform them of:
a. The telephone number that this unit is connected to,
b. The ringer equivalence number [1.4B]
c. The USOC jack required [RJ11C], and
d. The FCC Registration Number.
Items (b) and (d) are indicated on the label. The ringer equivalence number (REN) is
used to determine how many devices can be connected to your telephone line. In most
areas, the sum of the RENs of all devices on any one line should not exceed five. If too
many devices are attached, they may not ring properly.
Equipment Attachment Limitations Notice:
The Canadian Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective,
operational and safety requirements. The Department does not guarantee the equipment
will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment must
also be installed using an acceptable method of connection. In some cases, the
company's inside wiring associated with a single line individual service may be extended
by means of a certified connector assembly (telephone extension cord). The customer
should be aware that compliance with the above conditions may not prevent degradation
of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance
facility designated by the supplier. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications company cause
to request the user to disconnect the equipment.
