TK-272G/372G

A Starring Role in Every Situation, Every Application

Get a flying start with Kenwood's TK-272G/372G - tough

portables that offer top performance, operating ease and

versatility. Intergrated QT & DQT signaling, 32-channel memory

capacity, priority scan, High output (500 mW speaker), and a built-

in speaker mic jack are just some of the many features that make

these radios an unbeatable investment.

Strength & Durability

A clear demonstration of Kenwood's high standards of design, manufacturing and

quality assurance is the fact that our facilities are ISO-9001 certified. Reliability is built

into every one of our products from the component level up. So when it comes to

choosing the communications equipment on which your buiness must depend, you can

rely on the "Kenwood" brand.

Vertical Layered Design

In a fresh departure from the conventional stacked design, the battery pack forms the

entire back of the unit and the transceiver components from the front. This approach

results in a stronger chassis and a single PCB, and improves the overall styling and

appearance of the radio.

MIL-STD 810 C/D/E

The TK-272G/372G are manufactured along Kenwood's demanding technical and

industrial standards, meeting or exceeding the tough environmental standards used by

the U.S. Department of Defense. These radios pass U.S. MIL-STD 810 C/D/E standards

covering shock, vibration, humidity, dust, and rain, for reliable performance in even the

toughest conditions.

Die-Cast Chassis and Polycarbonate Case

The monocoque aluminum die-cast chassis-heat sinks borrows a

principal from aircraft construction for rigid strength. Surrounding this

and forming an integral part of the chassis, is the super-tough

polycarbonate case to provide years of durability. The heavy-duty belt

clip and antenna mount are also integrated into the chassis for

strengthened unit construction.

Weather-Resistant

Integrated elements like gasket seals and the polyvinyl speaker cone prevent moisture

penetration for confident wet weather use.

Performance

Kenwood employs the lastest in surface-mount techniques, multi-layer epoxy PCBs,

advanced integrated circuits and hybrid components to ensure that the TK-272G_372G

portables provide rugged, power-efficient performance.

Companded Audio

The Compandor noise-reduction feature enhances audio clarity on narrow bandwidth

systems and is programmable per channel. Voice intelligence components are amplified

and compressed at the transmit end then re-expanded on the receive end to reproduce

the original audio signal.

Heavy-Duty Antenna Mount

The antenna's industry-standard SMA connector provides improved mechanical and

electrical performance.

High Output Audio

A large 1-3/8 inch speaker provides 500 mW audio output. This enables the user to hear

transmissions clearly even in the noisiest environments.

User-Friendly Interface

An essential part of performance is operating ease. And thanks to a sophisticated

ergonomic layout, with carefully arranged controls, these radios are simple for anyone to

use. Setup and maintenence are also easy.

Alphanumeric LCD Display

The 8-channel display panel provides quick recognition of operating status and present

settings with alphanumeric and icon characters. For enhanced nighttime viewing,

pressing the backlight key illuminates the LCD display and keypad, and if no other keys

are operated, backlighting shut offs after 5 seconds.

Busy Channel Lockout

Lockout further improves channel management by preventing transmission if another

talk group is already on the air.

Built-IN QT and DQT Signaling

QT & DQT functions segregate talk groups so users only hear calls from their own group

for clearer, improved communications.

Built-In 2-Tone Decoder and Encoder

The decoder and encoder functions offer 2-tone paging code assignable to any channel.

An incoming message is signaled with audible and visible alerts.

Call Alert

Notifies you as to whether the call received had DTMF or 2-tone signaling.

DTMF Transpond

Transmits a code telling the caller that your radio received their DTMF paging signal.

Signaling And/Or Logic

For improved response when using combinations of signaling systems, squelch is

opened when either one, or all, signal requirements are met.

Dialing Features

Telephone interconnect is possible with the DTMF memory Auto-Dial and redial

features. Kenwood also offers the TK-270G/370G modles with full DTMF manual dialing

capabilities.

Two-Color LED

The two-color LED provides traditional transmit/warning (red), receive (green), and alert

(orange) visual indications. This LED is recessed to limit omni-directional visibility to

everyone except the radio operator.

Versatility

In a fast-moving world, technology has to remain flexible. And the TK-272G/372G

portables have been expressly designed to allow you to develop your communications

capabilties.

Flash Memory Advantage

Flash memory permits updates, advanced feature sets and system architectural

changes to be made electronically without ever opening the unit. This means fast

changes for the system operator and less down time for users.

Unit Cloning

Cloning enables duplication of radios in the field via a simple interface cable without the

use of a PC or special equipment.

Wide/Narrow Channel Bandwidth

The TK-272G/372G can be programmed for wide or narrow bandwidth operation per

channel to accommodate all channel allocations now and in the future.

High-Channel Capacity

32-channel cpapcity (semi-duplex) ensures plenty of room for applications today and

tomorrow. And once programmed, users can select specific channels within the set

range.

DTMF Decode

This feature adds another dimension to paging with convenient 3- to 10-digit DTMF

code combinations available. 3-digit ID plus 1-digit intermediate code SEL Call, and 1-

to 5-digit status code are also supported, as is DTMF group calling.

PC Programming and Tuning

Radio parameter programming and tuning can be accomplished via the accessory

connector from a PC-compatible computer without ever having to open the radio to

save both time and expense (requires optional programming cable and software).

Power Output Settings

Programmable power levels provide one of two settings (High/Low) for each of the

channels so the radio can be tailored for mixed transmit range requirements. Output

levels can be programmed at 5W/1W on VHF and 4W/1W on UHF.

ANI Function

Two types of ANI - PTT ID (per channel) and DIAL ID - send connect and disconnect ID

information. Repeater/RIC access is enabled through key operation or ID transmit with

PTT set to On.

Scan With Priority

Channel scanning provides users with an easy way to monitor multiple channels for

activity. Priority Scan enables the radio to automatically check for activity on an

important main channel during the channel scan sequence and while receiving a call on

another non-priority channel. Multi-group and single group scans are available to limit

scanning to the currently selected group or to scan all channel groups.

Dead Beat Disable (D.B.D.)

Useful when functions of the radio need to be rendered unusable, reception of a pre-

determined DTMF signal can either disable the units' signal transmission, or prohibit

signal transmission, while muting signal reception volume.

Embedded Message

The radio's flash memory can store an electronic message containing owner

identification, property I.D. numbers, user and department names, service records, etc.

A radio can be electronically identified even if external labels, markings or factory serial

numbers have been removed.
