FCC INFORMATION
FEDERAL COMMUNICATIONS COMMISSION
AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used
properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio
communication. It has been tested and found to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart J of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be necessary to correct the
interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the
Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

FCC REQUIREMENTS FOR TELEPHONE-LINE EQUIPMENT
1. The Federal Communications Commission (FCC) has established rules which permit this device to be
directly connected to the telephone network with standardized jacks. 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 the repair has
been made. If this is not done, the telephone company may temporarily disconnect service.
3. If you have problems with your telephone equipment after installing this device, disconnect this device
from the line to see if it is causing the problem. If it is, contact your supplier or an authorized agent.
4. The telephone company may make changes in its technical operations and procedures. If any such
changes affect the compatibility or use of this device, the telephone company is required to give
adequate notice of the changes.
5. 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.
c. The USOC jack required: RJ-11C.
d. The FCC registration number.

3
CDC STATEMENT
Items (b) and (d) can be found on the unit’s FCC 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 (5.0). If too many devices are attached, they
may not ring properly.
6. In the event of an equipment malfunction, all repairs should be performed by your supplier or an
authorized agent. It is the responsibility of users requiring service to report the need for service to the
supplier or to an authorized agent.
CERTIFICATION NOTICE FOR EQUIPMENT USED IN CANADA
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications-network protective, operation, 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 (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—in this case,
your 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.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.

MULTI-PURPOSE AMPLIFIER AND TWO-PRONG CARBON AMPLIFIER
CAUTION:
Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority,
or electrician, as appropriate.
The LOAD NUMBER (LN) assigned to each terminal device denotes the percentage of the total load to be
connected to a telephone loop which is used by the device, to prevent overloading. The termination on a
loop may consist of any combination of devices, subject only to the requirement that the total of the load
numbers of all the devices does not exceed 100.

4.1 Setup Process 1
If your phone system appears in
Table 4-1, follow these steps to set
up your amplifier. You will not be
able to achieve compatibility
without first following all of the
setup instructions.
1. Remove the lid for the
battery compartment by
sliding it to the left and then
lifting it off. See Figure 4-1.
Figure 4-1. Removing the Lid.
2. Adjust the telephone type
switch according to
Table 4-1.
Figure 4-2. Adjusting the Telephone Type
Switch.
3. If batteries are required
according to Table 4-1,
insert two AA batteries as
indicated on the bottom of
the battery compartment.
See Figure 4-3.
Figure 4-3. Inserting the Batteries.
4. Make a call and adjust the
transmit control according
to the level indicated in
Table 4-1 or to a satisfactory
level. See Figure 4-4.
Figure 4-4. Adjusting the Transmit Control.
5. To replace the battery lid,
align it at the right-hand
side of the battery
compartment and press
down. Then slide it to the
right. See Figure 4-5.

4.2 Setup Process 2
If your telephone system does not
appear in Table 4-1, follow this
process. You will not be able to
achieve compatibility without
completing all the points included
in Chapter 3, How to Make a Call.
1. Remove the lid for the
battery compartment by
sliding it to the left and then
lifting it off.
Figure 4-6. Removing the Lid.
2. Make sure that the
telephone type switch is in
position C.
Figure 4-7. Adjusting the Telephone Type
Switch to Position C.
3. Take the phone off the
hook and make a call. If you
do not get a dial tone, go to
setup process 2a on the next
page. If you achieve a
connection, adjust the
transmit control to either
position 1 or 10. (The
middle settings of the
transmit wheel have little
effect in telephone type C
setting. Setting 1 or 10 will
give the best results.)
