The Grand Tour 1
This chapter familiarizes you with the Strata CTX DKT2204-CT and DKT2304-CT
Cordless Digital Telephones (e.g., handset, batteries, base and charging units, fixed
buttons). Chapter 4 – Feature Access Codes, beginning on p age 37 covers the four
pre-assigned flexible buttons.
Your cordless digital telephone is engineered to work with your Toshiba digital
telephone system and provide you with reliability, long life, and outstanding
performance.
The cordless digital telephone is compatible with all Strata CTX and Strata DK
telephone systems (exce pt Strata DK24/5 6/96, Release 3). All it requires for
connection is a digital station port.
Fully charged, your cordless digital telephone provides:
• DKT2204-CT: six hours of talk time and four days of standby time.
• DKT2304-CT: seven hours of talk time and five days of standby time.
There is a fast charger in the handset and a trickle charger in the base.
You can use your cordless as a stand-alone phone attached to a digital port, or in
conjunction with a DKT3000/2000-series digital telephone—in which case both
phones share the same digital port a nd exte nsion nu mber. You c an swit ch betwe en use
of your DKT and your cordless, just by pressing a button.
Note If using a DKT3000 digital telephone, it must be set to operate in DKT2000
mode.
Strata CTX DKT2204-CT/DKT2304-CT Cordless Digital Tel ephones 06/03 1
The Grand Tour
Technology
Some of its features are:
• Liquid Crystal Display (LCD) that wraps using two lines, total of 32 characters
• Ringer and handset volume control
• Single button access to: Conference, Hold, Redial, Message and Transfer features
• Four programmable function buttons
• Charging stand (with spare battery charging capability on DKT2204-CT)
• AutoStandby
• AutoTalk
• Vibrate ringer alert
• Out-of-range protection
• Low-battery protection system
• Wall-mountable separate base and charging unit
• Headset jack (2.5mm)
• Stand-alone or DKT operation
• High quality ultra-secure conversation with 32Kbps Adaptive Differential Pulse
Code Modulation (ADPCM) voice code combination.
• Three ring tones
Technology
Your DKT2204-CT uses digital 900 MHz spread-spectrum technology, which
represents state-of-the-art design and engineering. The DKT2304-CT uses 900 MHz
Digital Narrow Band technology. These technologies provide:
• Unsurpassed range, several times greater than conventional analog or cordless
digital telephones.
• Clarity that is so good, it is indistinguishable from corded telephones in most
environments.
• (DKT2204-CT) Fully secure communications for up to 10 cordless digital
telephones within a given environment.
• (DKT2304-CT) Maximum security for up to 30 cordless digital telephones that is
almost impossible to scan.
2 Strata CTX DKT2204-CT/DKT2304-CT Cordless Digital Telephones 06/03
Applications
Your cordless digital telephone brings mobility and productivity to office telephones.
Greater call access cuts down on “telephone tag” delays. Its compact design makes it
easy to take with you.
Benefits
Your cordless digital telephone uses advanced technology and provides important
features that place it far above the compe ti ti on i n func ti onality and value. You benefit
from much greater performance than other cordless telephones currently available.
This means better sound quality, longer range, greater security, multi-line access,
helpful LCD display information, and many other important advantages.
The cordless digital telephone provides many advantages over a single-line analog or
digital telephone. Some of those advantages are:
• Your cordless digital telephone has four flexible feature buttons. They have the
same functions as the first four buttons on the 3000/2000-series desk DKT. If you
do not use these buttons for the assigned features, you can invoke other features
with access codes.
The Grand Tour
Applications
• Your cordless digital telephone rings to the same extension number as the regular
DKT it is used with, enabling you to answer via either telepho ne. Both follow the
same forwarding and hunt ing r egardl ess of which t elephone is in use . This i s much
simpler than having a separate extension number and standard station port for a
single-line cordless.
• An SLT cordless is not only a cumbersom e alternative to the Toshiba digital
cordless; but also, if you forget to forward your calls, you cannot receive the calls
on your SLT cordless. With your cordless digital telephone it is easy. Just press a
button, grab your cordless, and go!
• A Message Waiting icon appears on the LCD when message(s) are in the
user’s mailbox.
In addition to the benefits mentioned above, the DKT2204-CT also has the following
benefits:
• Spread-spectrum technology provides five to seven times greater range than
conventional cordless telephones, making your cordless digital telephone much
more useful and valuable.
Strata CTX DKT2204-CT/DKT2304-CT Cordless Digital Tel ephones 06/03 3
The Grand Tour
Handset
• 900 MHz spread-spect rum oper ation pro vides maximu m secu rity with a freq uency
range that is almost impossible to scan. Regular 900 MHz cordless digital
telephones are difficult to scan, but less so than spread spectrum. Analog cordless
telephone frequencies are easy to scan and provide virtually no security from the
outside. Hackers and thieves can use this to hear conversations and pick up credit
card numbers.
• Sound quality is better on your cordless digital telephone than non-spread
spectrum 900 MHz digital cordless telephones. Sound quality on conventional
analog cordless telephon es is s o poor by compari son that they ar e onl y practi cal for
short range usage.
Handset
Your cordless handset has special function buttons (shown below) and an LCD that
shows operating conditions.
Note The handset and bas e unit of your cordl ess t eleph one is equipp ed with the sa me
security code. In order for this handset to operate, it must be installed with the
matching base unit.

Low Battery
Your cordless telephone comes equipped with one rechargeable battery:
• DKT2204-CT: BT2499 battery that provides six hours of talk and four days of
standby time (fully charged).
• DKT2304-CT: BT930 battery that provides seven hours of talk and five days of
standby time (fully charged).
A “fast charge” in the handset and a “trickle charge” in the charging unit enables the
extended talk and standby times.
When the battery is low, the Battery icon displays on
the LCD (shown right) and the handset beeps. Low
battery symptoms are:
• On a call
• All buttons and functions operate
• Handset beeps once every three seconds
Note To continue your call, you must replace the battery pack within 20 seconds.
• In standby mode
• None of the buttons operate
• LCD messages are cleared
• Handset beeps every 15 seconds for three minutes
• Cannot make or receive call
T o resto re your bat tery capa city, return the handset to the charging uni t for char ging or
replace the handset battery with a charged one. If the handset is on the charging unit
for one minute, battery low condition is cancelled. The Battery icon is turned Off and
battery low tone stops.
For more information on installing and charging the battery, see Step 8: “Install
Handset Battery Pack” on page 23.

Cleaning Charging Unit Contacts
To maintain a good charge, it is important to clean all
charging contacts on the handset, spare battery pack
(DKT2204-CT only) and charging unit about once a
month (shown right). Use a pencil eraser or a soft dry
cloth. Do not use any liquids or solvents.

Charging Spare Battery Packs (DKT2204-CT only)
The charging unit of your cordless telephone is equipped to charge the spare battery
pack with or without the handset in the front slot.
1. Slide the spare battery pack into the second slot in the
charging unit until the retaining clip snaps over the top of
the pack.
2. Make sure the
%$77&+$5*( indicator doesn’t light, check to see that
%$77&+$5*( indicator lights. If the
the AC adapter is plugged in, and that the battery pack is
making good contact with the unit’s charging contacts.
Note Charge the battery pack without interruption for 12~15
hours.
3. When charging is complete, press out on the latch and
remove the battery pack for use. Or, if you don’t need the
battery pack immediately, leave it in the charging compartment. It will not
overcharge.

Simultaneous Convers ati on Chann el s
Simultaneous Conver sation Channels
DKT2204-CT
The DKT2204-CT cordless digital telephone has 10 operating channels available.
A common misconception is that this limits a customer to 10 cordless telephones. This
is not the case. Each cordless digital telephone can operate on any of the 10 channels.
When you turn on a cordless digital telephone, the telephone selects an available
channel within its’ range. In a given cordless range, 10 simultaneous calls can be
made. In most businesses, it is unlikely that all 10 channels will be in use at the same
time. Typically 20 to 30 telephones can share the 10 channels.
Another factor i s the dist ribut ion of the t el ephones in a faci lity. If your cordless digital
telephones are disbursed throughout a facility, there should not be contention for
channels. If ther e are more th an 10 cordl ess dig ital te lephones i n one area an d 10 user s
are using their cordless telephones, an 11
time.
DKT2304-CT
The DKT2304-CT cordless handset has 30 operating channels available. A common
misconception is that this limits a c ustomer to 3 0 handsets. T his is not the case. Each
handset can operate on any of the 30 channels because each one selects an available
channel within its range. In a given range, 30 simultaneous calls can be made.

Another factor is the distribution of the telephones in a facility. If your handsets are

Range and Performance
Range and Performance
The DKT2204-CT operates up to 1.1 miles and the DKT2304-CT .7 miles from its
base in a completely unrestricted test environment. Typically, ranges of 300 to 400
feet are possible, dependi ng on t he buil ding s truct ure i n which it i s used. For opt imum
range and performance from your handset, try the following:
• Place the base units at least three to six feet away from the DKT; three feet from
metal structures; and six feet from computers, fax machines or other electronic
equipment.
• Use an AC outlet not associated with computer or electromagnetic equipment.
• Wherever possible, put the base unit in the middle of the coverage area.
• Mount the base unit high in the room for maximum range.
• If you have two to three cordless telephones, put them 12 feet apart.
• If you have four to 10 cordless telephones, put them 20 feet apart.
• If you want to use more than one cordless telephone in your office, they must
operate on different channels. Press the
CT) button on the handset to select a channel that provides the clearest
communication.

Radio Interference
Radio interference occasionally interrupts conversations, which does not mean that
your unit is defective. Move to a different location while you are talking. If the
interference continues, move the base unit. If there is still interference, contact your
System Administrator.
Telephone Line Problems
The FCC and IC have 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 may 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.
50 Strata CTX DKT2204-CT/DKT2304-CT Cordless Digital Telephones 06/03
If you are having trouble with your telephone service, you must first disconnect your
telephone to dete rmine i f it is the ca use of your pr oblem. If you det erm ine th at it is th e
cause, you must leave it disconnected until the trouble has been corrected.
Privacy
Cordless telephones are radio devices. Communications between the hand set and base
unit of your 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, your communications can be received by radio receiving devices other than
your own cordless telephone unit. Consequently, any communications using your
cordless telephone may not be private.
