This product is equipped with a three-wire grounding-type plug with a third (grounding)
pin. This plug will only fit into a standard ground-type power outlet. If you are unable to
insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do
not cut or remove the grounding prong or use 2-wire extension cords or adapters to defeat
this safety feature of the product.
Do not allow anything to rest on the power cord. Do not locate this product where the
cord will be abused by persons walking on it.
Do not overload wall outlets and extension cords as this can result in the risk of fire or
electric shock.
Never push objects of any kind into this product through cabinet slots as they may touch
dangerous voltage points or short out parts that could result in a risk of fire or electric
shock.
Never spill liquids of any kind on the product.
To reduce the risk of electric shock, do not disassemble this product. There are no user
serviceable parts inside. Incorrect reassembly can cause electric shock when the unit is
subsequently used.
Unplug this product from the wall, remove the cords from the modular jacks in the unit,

—
—
—
—
—
When the power cord or plug is damaged or frayed.
If liquid has been spilled into the product.
If the product has been exposed to rain or water.

Avoid using the product during an electrical storm. There may be a remote risk of electric
shock from lightning.
If you suspect a gas leak, report it immediately, but use a telephone away from the area in
question. The telephone’s electrical contacts could generate a tiny spark. While unlikely,
it is possible that this spark could ignite a heavy concentration of gas. This product is not
approved for use in areas labeled by the Occupational Safety and Health Administration
(OSHA) as "explosive environments." Only "Explosive Atmosphere Telephones" may be
used in such hazardous environments.

1-2 Introduction

PRINCIPLES OF OPERATION
The MERLIN PFC Telephone consists of two modules: a voice module and a facsimile module, each
operating separately from the other. Two ports on the communication system controller are required for
the MERLIN PFC Telephone, two "wire runs" are needed (one for voice and one for facsimile), and
there are two jacks provided on the telephone. The voice jack on the MERLIN PFC Telephone is
labeled Voice Line and requires an analog (ATL) or hybrid port connection. The facsimile jack on the
telephone is labeled
Line and also requires an analog (ATL) or hybrid port connection.
The voice module is identical in operation and administration to a BIS-34D display telephone.

Figure 1-1. MERLIN PFC Telephone and Facsimile Buttons and Lights
The MERLIN PFC facsimile panel has four indicator lights and three buttons (see Figure 1-1). All four
lights are controlled by the facsimile module. The Stop and Copy buttons are connected to the
facsimile module and control its operation. The Start button is not connected to the facsimile module
but is connected to a button of the voice module (the fourth button from the bottom on the right). This
button is called FAX on the voice module’s button label sheet. Pressing the
Start button is the same as
pressing the FAX button on the telephone and the two can be used interchangeably. A block diagram of
these two modules is in Figure 1-2.

To send a facsimile the following sequence of operations must occur:
●
Insert the original document in the document feeder, face down.
●
Dial a call to a facsimile machine using the voice module.
●
Transfer the call to the facsimile station, using the transfer function of your communication system.
This can be done using the one touch transfer feature, or pressing
Transfer followed by a station or
intercom button, or
Transfer followed by dialing the facsimile station/intercom number.
The facsimile station will now be rung, and the facsimile module will automatically answer. No ring
will be heard. The facsimile module, sensing an original document in the document feeder, will
enter transmission mode to send the facsimile.
To receive a facsimile automatically:
The document feeder must be empty.
●
●
The call must be dialed directly to the facsimile station or routed by an attendant to that station.
The facsimile station will now be rung, and the facsimile module will automatically answer (as
above). No ring will be heard. The facsimile module, sensing an empty document feeder, will enter
reception mode to receive and print the facsimile.
