following:

T Read and understand all instructions.

T Follow all warnings and instructions marked on the product.

T Unplug this product from the wall outlet before cleaning. Do not used liquid

cleaners or aerosol cleaners. Use a dry cloth for cleaning.

T Do not use this product near water; for example, near a sink or in a wet area.

T Do not place this product on an unstable cart, stand, or table. The telephone

can fall, causing serious damage to the unit.

T To protect the product from overheating, do not block or cover any slots or

openings in the base unit. This product should never be placed near or over a
radiator or heat register. This product should not be placed in a built-in
installation unless the proper ventilation is provided.

T This product should be operated only from the type of power source indicated

on the marking label.

T Do not allow anything to rest on the power cord. Do not locate this product

where the cord will be damaged by people walking on it.

T Do not overload wall outlets and extension cords, as this can result in the risk of

fire or electrical shock.

T Never push objects of any kind into this product through the base unit slots, as

they may touch dangerous voltage points or short out parts that could result in a
risk of fire or electrical shock. Never spill liquid of any kind on the product.

T To reduce the risk of electric shock, do not disassemble this product. Contact

qualified service personnel when some service or repair work is required.
Opening or removing covers may expose you to dangerous voltages or other
risks. Incorrect reassembly can cause electric shock when the appliance is
subsequently used.

T Unplug this product from the wall outlet and refer servicing to qualified service

personnel under the following conditions:

P When the power supply cord is damaged or frayed.

P If liquid has been spilled onto the product.

P If the product has been exposed to water or rain.

Cordless DECT

these instructions.

P Use only the appropriate type and size battery pack specified in the manual.

P Exercise care in handling the battery in order not to short the battery with conducting

materials such as rings, bracelets, and buttons. The battery or conductor can
overheat and cause burns.

Privacy

Cordless telephones are radio devices. Communications between the handset and
base of the cordless telephone are accomplished by means of radio waves which are
broadcast over the open airways. Because of the inherent physical properties of
radio waves, communication can be received by radio receiving devices other than
your own telephone unit, consequently, any communications using the cordless
telephone may not be private.

SECTION 4IMPORTANT ELECTRICAL CONSIDERATIONS

Do not attempt to unplug any appliance during an electrical storm.

Unplug all electrical appliances when you know an electrical storm is approaching.
Lightning can pass through your household wiring and damage any device connected
to it. This telephone is no exception.

Caution:

Changes or modifications to this product not expressly approved by
NEC Unified Solutions,
other than as detailed by this manual, could void your authority to
operate this product.

Inc., or operation of this product in any way

Cordless DECT Document Revision 1

___________________________________________________________________________________

Range

Nominal values of the DECT system are:

T 164 feet (50 meters) – Indoor

T 984 feet (300 meters) – Outdoor

The telephone is designed to achieve a maximum range of up to 350 feet (depending
upon the environment), by transmitting and receiving according to the highest
specifications set forth by the FCC. We have rated this phone to operate at a
maximum distance with the qualification that the range depends upon the
environment in which the telephone is used. Many factors limit range, and it would be
impossible to include all of the variables in our rating. The maximum range rating of
this telephone is meant to be used as a means of comparison against other range
claims.

Telephone Line Problems

The FCC has granted the telephone company the right to disconnect service in the
event that your telephone causes problems on the telephone line. Also, the
telephone company may make changes in facilities and services which can affect the
operation of your unit. However, your telephone company must give adequate notice
in writing prior to such actions to allow you time for making necessary arrangements
to continue uninterrupted service.

If you are having trouble with your telephone service, you must first disconnect your
telephone to determine if it is the cause of your problem. If you determine that it is the
cause, you must leave it disconnected until the trouble has been corrected.

Radio Interference

Radio interference may occasionally cause buzzing and humming in your cordless
handset, or clicking noises in the base unit. This interference is caused by external
sources such as TV, fluorescent lighting, or electrical storm. Your unit is NOT
DEFECTIVE. If these noises continue and are too distracting, check around your
office to see what appliances may be causing the problem. In addition, we
recommend that the base not be plugged into a circuit that also powers a major
appliance because of the potential of interference. For best performance, ensure that
the antenna on the base unit is fully extended.

In the unlikely event that you consistently hear other voices or distracting
transmissions on your telephone, you may be receiving radio signals for another
cordless telephone or other source of interference.

___________________________________________________________________________________

Owner’s Guide 1 - 5

Document Revision 1 D

___________________________________________________________________________________

term

Cordless DECT

Finally, it should be noted that some cordless telephones operate at frequencies that
may cause interference to nearby TVs and VCRs. To minimize or prevent such
interference, the base of the cordless telephone should not be placed near or on top
of a TV or VCR. If interference is experienced, moving the cordless telephone farther
away from the TV or VCR will often reduce or eliminate the interference.

More than One Cordless Telephone

If you want to use more than one cordless telephone in your office, they must operate
on different channels and more than 20 feet apart.

If more than eight DTL-8R-1s are used in the same area, there is a possibility that the
following problem occurs:

T Difficulty connecting the Handset with the Base Unit

T Some noises can be heard during conversation

The DTL-8R-1 is limited to five RF channels. The RF channel is changed
automatically to find the best channel.

Depending on your environment, the maximum number of cordless devices used
without interference varies.

Multiple base and handset units should not be closer than 20 feet at any time.

Radio interference causes interruptions in conversation. When this happens, your unit
is not defective. When noise continues, move to a different location while you talk.
(You might even need to move the base unit.) When the situation persists, contact the
National Technical Assistance Center (NTAC).

SECTION 4APPLYING POWER TO THE CHARGING UNIT

The unique design of the telephone allows the user to place the handset in the
charging unit with or without the belt clip attached. The charging unit can charge a
second battery with or without the handset being charged. The battery packs can
automatically be recharged either in or out of the handset.

Figure 3-3 Applying Power to the Charging Unit

Use only the supplied AC adapter for the charging unit.

The AC adapter furnished with this telephone may be equipped with a polarized line
plug (a plug having one blade wider than the other). This plug will fit into the power
outlet only one way. If you are unable to insert the plug fully into the outlet, try
reversing the plug. Refer to Figure 3-4 Polarized Plug.

If you cannot plug the AC adapter into the outlet, the outlet may need to be replaced.

Route the power cord where it will not create a trip hazard, or
where it could become chafed and create a fire or other electrical
hazards.

5.2 Mounting the Base Directly to the Wall

If a standard wall plate is not available, mount the telephone directly on the
wall. Before mounting the telephone, consider the following:

 Select a location away from electrical cables, pipes, or other items

behind the mounting location that could cause a hazard when inserting
screws into the wall.

 Make sure the wall material is capable of supporting the weight of the

base unit.

 Use #10 screws with anchoring devices suitable for the wall material

where the base unit will be placed.

To mount the telephone:

1. Insert two mounting screws 3-15/16" apart. Allow 3/16" between the wall
and screw heads for mounting the telephone.
