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 builtin 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 1to 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 predetermined 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.
SmarTrunk™ Omni Board Compatable
Expand to conventional and conventional system capacity with the OMNI board,
available from the SmarTrunk™ Corporation.
