SECTION 3  BATTERY SAFETY
This equipment contains rechargeable nickel-metal hydride (Ni-MH) batteries. 
Do not short-circuit the batteries.
Do not charge the rechargeable Ni-MH batteries used in this equipment in any 
charger other than the one designed to charge these batteries as specified in 
this manual.  Using another charger can damage the batteries or cause the 
batteries to explode.
Use only the appropriate type and size batteries specified in this manual.
Do not open or mutilate the batteries.  Released electrolyte is corrosive and 
can cause damage to the eyes or skin.  It may be toxic if swallowed.
Exercise care in handling the batteries in order not to short the batteries with 
conducting materials such as rings, bracelets, and buttons, etc.  Shorting the 
contacts on the batteries can cause overheating and burns.
Observe proper polarity orientation when installing the batteries.
Do not dispose of the batteries in a fire; they may explode.
Do not place the batteries in your regular trash. Ni-MH batteries must be 
collected, recycled, or disposed of in an environmentally sound manner.  
Contact your local waste management officials for other information regarding 
the environmentally sound collection, recycling and disposal of the battery 
contained in this product.

Owner’s Manual1-5
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 small 
enclosure unless proper ventilation is provided.
This product should be operated only from the type of power source indicated 
on the marking labels.

where the cords will be damaged by people walking on them.
Do not overload wall outlets and extension cords, as this can result in the risk 
of fire or electrical shock.
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.
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.
Unplug this product from the wall outlet and refer servicing to qualified service 
personnel under the following conditions:
If you see smoke coming from the unit, or if it smells burned.
When the power supply cord is damaged or frayed.
If liquid has been spilled onto the product.
If the product has been exposed to water or rain.
If the product does not operate normally when following the operating instructions.

1-6Specifications and Safety Information
SECTION 5  PRIVACY
Cordless telephones are radio frequency devices.  Communications between the 
handset and base unit 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 6  IMPORTANT ELECTRICAL CONSIDERATIONS
6.1 Electrical Safety
Unplug all electrical appliances when you know an electrical storm is 
approaching.  Lightning can pass through wiring and damage any device 
connected to it.  This telephone is no exception.
6.2 Range
Nominal values of the DECT system are:
164 feet (50 meters) – Indoor
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.  This telephone has been rated 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 the rating.  The maximum 
range rating of this telephone is meant to be used as a means of comparison 
against other range claims.    
6.3 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 
 WARNING
Do not attempt to unplug any appliance during an electrical storm.
 CAUTION
Changes or modifications to this product not expressly approved by 
NEC Corporation of America, or operation of this product in any 
way other than as detailed by this manual, could void your authority 
to operate this product. 
						

							Issue 1.0
Owner’s Manual1-7
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.
6.4 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 a PC, TV, fluorescent lighting, or electrical storm, etc.  
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 unit 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.  It may 
also be necessary to re-locate the base unit  
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.  
Finally, it should be noted that some cordless telephones operate at frequencies 
that may cause interference to nearby TVs or other electronic equipment.  To 
minimize or prevent such interference, the base of the cordless telephone should 
not be placed near or on top of other electronic equipment.  If interference is 
experienced, moving the cordless telephone unit farther away will often reduce or 
eliminate the interference.
6.5 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 must be more than 20 feet (6m) apart.  
If more than eight DTZ-8R-1s are used in the same area, there is a possibility that 
the following problem occurs:
Difficulty connecting the Handset with the Base Unit
Some noises can be heard during conversation
The DTZ-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. 
						

							Issue 1.0
1-8Specifications and Safety Information
Multiple base and handset units should not be closer than 20 feet (6m) 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).
