Trunked Format provides both programmable LTR® trunked and conventional systems, partitioned for operation on multiple systems. LTR trunking systems automatically provide communications on any available channel within a pool of channels on each system.
These radios feature all traditional LTR trunking functions such as System Scan & Group Scan for multiple system/multiple talk group calling, Fixed Priority IDs, Transmit Inhibit and a Decode ID Block allow convenient dispatcher fleet control and monitoring. Conventional system partitions are programmable for multiple channels. Priority scan permits scanning of all channels while simultaneously monitoring a priority channel, allowing for activity even while receiving a call on another non-priority channel.

¹ Trunked Format, priority scan is only available within one conventional system partition; it can not check channels on other programmed conventional or trunked system partitions.

CONVENTIONAL FORMAT
Conventional Format provides traditional operation programmable for multiple channels in one contiguous channel group or multiple channel groups accommodating different geographical areas, user organizations, special use or temporary requirements. Set priority scan for single group or multiple group scan so you can scan a current channel group while scanning all other groups.

LARGE CHANNEL CAPACITY
The demands of large systems, multiple systems and growing fleets are accommodated with the large-capacity 32 Systems / 250 Group IDs in Trunked Format or 250 channels in Conventional Format.²

Trunked format operation offers both system and group scan, permitting monitoring of calls on multiple systems and multiple talk groups per system. Priority scanning is available within programmed conventional systems. Conventional format operation permits single priority scanning within a single channel group or among multiple channel groups. Talk Back scan permits users to respond immediately to calls regardless of the pre-programmed or selected scan revert channel.

FleetSync™ ADVANTAGE :

FleetSync™ DIGITAL MESSAGING & SIGNALING -"BASIC"

The FleetSync "Basic" feature set is included in each radio providing a cost-effective fleet unit identification, selective calling and messaging system for dispatch operations.³ Each radio can have an ID with a unique Fleet and Unit number. This is used for all FleetSync signaling and data messaging (250 fleets/ 4000 units per fleet), allowing large fleets or multiple fleets to share the same radio system(s).

PTT ID is a digital ANI (Automatic Number Identifier) that can be sent on each PTT using the FleetSync 10. An associated alphanumeric username can be displayed on an SD-Series base mobile LCD (Caller 10* enabled), a base station decoder unit or dispatch software. Personnel are clearly identified during mission-critical tasks so the dispatcher/supervisor can immediately confirm who is talking, thus maximizing fleet management efficiency and call processing.

Caller ID Stack* stores (in volatile memory) the three most recently received PTT IDs for recall and review, allowing a user to check for missed voice calls.

Selective Calling permits a base station and/or fleet radios to signal individual radios or groups of radios by simply selecting their FleetSync 10 and hitting PTT. The receiving radio(s) are call alerted.

Extended Status Message List (50*) provides up to 50 pre-stored sixteen-character alphanumeric messages permitting a base to send a larger variety of job task messages. Fleet radios can display and respond accordingly with appropriate acknowledgements.
Special reserved Emergency, Emergency Man-down*, Emergency Mode Off *, Horn Alert (mobiles)* and Radio Stun/Acknowledge/Resurrect statuses are provided.

The FleetSync Enhanced option extends the FleetSync Basic feature set to include custom Short Text Messaging, Long Text Messaging, and the FleetSync PC Serial Interface.

PC Serial Interface enables serial communications between a FleetSync-capable mobile radio (e.g. SO-Series model) and a FleetSync- compatible peripheral device or dispatch software.4

 4 Short Tex! Messaging requires a FleetSync-capable base station mobile to be serially interfaced via the "PC Serial Interface" feature with a computer running FLeetSync-compatible dispatch software.

PERFORMANCE:

IMPRESSIVE SPECIFICATIONS, WORLD-CLASS PERFORMANCE
High-stability 2.5PPM oscillators, an efficient MOS-FET power module and advanced filtering are just some of the engineering features that give these transceivers the performance and power to serve in any modern radio system.

WIDE-BAND COVERAGE
A discrete MOS-FET power module results in wide coverage for local, regional and statewide frequency needs. This wide- band coverage means both traditional and newly allocated frequencies can be accommodated.

COMPANDED AUDIO
The compander noise-reduction feature enhances audio clarity especially on wide and narrow bandwidth systems and is programmable per channel. Voice intelligence components are amplified and compressed at the transmit end then re-expand- ed on the receive end to reproduce the original audio signal. This feature works on wide and narrow band channels.

WIDE BATTERY SELECTION
Kenwood offers a lightweight Li-Ion battery (KNB-24l), ideal for low- temperature environments; a durable  Ni-Cd battery (KNB-25A); and a powerful Ni-MH battery (KNB-26N) for extra- long life.
A convenient and exclusive Kenwood feature is the battery status indicator (High/Sufficient/Low Very Low), giving the user an immediate visual indication of the amount of charge left. The belt clip is designed to stay in place when changing batteries.

STRENGTH & DURABILITY:

MIL-STD 810 C/D/E ENVIRONMENTAL TESTS
In addition to Kenwood's own demanding technical and industrial standards, the TK-2140/3140 meets or exceeds all the tough US Department of Defense MIL-STD 810 C, D & E environmental standards in eleven categories including the demanding driven rain standard. This means that you can count on these radios to keep on performing even in storm-like conditions.

DIE-CAST CHASSIS
The aluminum die-cast chassis contributes to the TK-2140/ 3140's durability and strength while facilitating heat dissipation. The super-tough polycarbonate contoured case contributes to durability for many years of use in rough conditions.

WEATHER-SEALED UNIVERSAL CONNECTOR
The universal accessory connector and battery contacts use spring-action gold-alloy elements for excellent contact, conductivity and anti-corrosive properties. The universal connector is designed for compatibility with many other Kenwood audio accessories such as the KMC-25 while maintaining compatibility with MIL-STD 810C, D & E standards.

SECURITY:

PASSWORD-PROTECTED PROGRAMMING AND CLONING
Cloning enables field duplication of radios using a simple inter- face cable, without a PC or special test components. For users who do not require this cloning capability, programming a secure password prevents cloning of a lost or stolen portable. As a further security measure, all radios can have the programming password(s) protected to prevent unauthorized program information extraction and duplication.

RADIO-LOCK PASSWORD
Preventing unauthorized use of lost or stolen portables, this feature requires an access code - with a maximum of six digits - to be entered every time the radio is powered up.

EMBEDDED MESSAGE
The radio's flash memory can store an electronic message containing owner identification, property 10 numbers, user and department names, service records, etc. A radio can be electronically identified even if external labels, markings or factory serial numbers are removed.
