VHF Compact Synthesized FM Mobile
The Kenwood TK-780 Multi-Mode wireless mobile radio operates
on multiple systems types: traditional two-way conventional repeater and
simplex, trunking (LTR) with wide or narrow bandwidth.
Radios have large channel capacity: 600-channel
in Trunked Mode and 250-channel in Conventional Mode. It provides
more than enough channel space for company-wide, departmental and divisional
requirement. The unit dynamically allocates the 32 system and 250-group
memory capacity as system parameters are programmed. Each programmed system
can be either set for either conventional or trunked operation.
The high-resolution dot matrix liquid crystal display
furnishes the user with a simple easy-to-read interface.
System scan and group scan permit monitoring multiple
systems and talk groups for calls. Priority scanning is available with
programmed conventional systems. Talk Back scan permits users to respond
immediately to calls regardless of the pre-programmed or selected scan
Alphanumeric Two-Way paging (available soon). Two-Way
Alphanumeric Messaging provides the built-in capability to send and receive
both pre-stored status messages and custom alphanumeric text messages.
The received messages are stored in memory and can be reviewed. Each
unit has an electronic serial number for message identification.
The TK-780 mobiles have a Data Connection Port
for external mobile data terminals, PC-modems (requires KCT-19 option),
or Automatic Vehicle Location units.
Each key is programmable for virtually any radio
feature allowing the unit to be customized to fit user needs. Sophisticated
feature sets are available for special applications and supervisory personnel.
Flash memory, programming and cloning permit to
make updates, advanced feature sets and system architectural changes without
ever opening the unit. The radiosís flash memory can store an electronics
embedded message containing owner identification, property ID numbers,
user and department names, service records, etc. Cloning enables duplicating
of radios in the field via a simple interface cable without the use of
a PC. Additionally, all radios can have the programming password protection
to prevent unauthorized program extraction and duplication.
The TK-780 is equipped with an extra-large 2.25-inch
speaker element and delivers four watts of audio power for robust clarity
in noisy crowds and industrial environments.
The TK-780 lightweight and compact size facilitates
easy mounting even in the tight or awkward positions of today's vehicles.
The front panel can be inverted for correct viewing while leaving the built-in
speaker facing away from the mounting surface. The lightweight aluminum
die-cast chassis contributes to the TK-780 units' exceptional strength
while providing natural transmit heat dissipation.
The radios have high quality audio with 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.
Public Address (PA) and Horn Alert (HA) capability
is available with the optional KAP-1 unit. The PA functions outputs mic
audio through the radios external speaker or can feed a more powerful external
public address amplifier. The Horn Alert output can be used to trigger
a vehicle horn/light when a valid DTMF or Two-tone selective call is received.
DTMF keypad and microphone provide selective calling,
system access, remote control applications and access to automatic dialing
features such as the auto-dial memory for telephone interconnect and/or
integrated Radio-PABX systems.
The Kenwood TK-780 meets or exceeds a full range
of tough U.S. Department of Defense MIL-STD 81 0 C, D & E environmental
Encryption control (optional) provides secure voice
communications for law enforcement or private security from low-level inversion
to high-level encryption types.
Radio lock password feature prevents unauthorized
use of stolen radios with an access code to be entered every time the radio
is powered up.
