| For mobile communications with
maximum performance and operating convenience in
an ultra-compact package, look to new TK-768/868
Series synthesized dash-mount radios. Synthesized
channel frequency generation provides up to 32 semi-duplex
channels for any application, from the simplest
to the most sophisticated. Wideband design provides
coverage across the most common VHF & UHF bands.
VHF: 148 ~ 174 MHz and 136 ~ 156 MHz. UHF: 450 MHz
~ 476 MHz, 470 MHz ~ 496 MHz, 488 MHz ~ 512 MHz,
and 400 MHz ~ 425 MHz.

- Advanced design RF power modules
provide an economic choice between low and high
power models with power output of 45W or 25W for
TK-768 Series and 35W or 25W for TK-868 Series.
- Priority scan allows user to
monitor multiple channels for calls and if need
be, prioritize a main channel. Other features
such as programmable reverts, delete/add, and
off-hook scan allow the radio to be customized
for both simple and sophisticated users.
- Emergency function is available
to secretly notify the dispatcher that an emergency
has arisen.
- The user-selectable tone function
allows operators to temporarily re-programme the
radio's signal tone; this permits communication
with talk groups outside of their own.
- PC programmability means even
complex radio configurations are easily and accurately
implemented and stored. For enhanced flexibility
in the field, technicians can programme the radio
using the "self-program" mode or wired
clone function.
- A large, easy-to-read LCD display
renders clear legibility under any lighting conditions.
Channel and operational status information are
shown using large, easy-to-understand indicators.
- "Installation-ready" ultra-compact
and lightweight design.
Today's vehicles are limited in space and mounting
surface which makes the 140mm (5.5-inch) width
and the mere 1kg (2.2 lbs) weight an installer's
dream. Each mobile package includes an adjustable
mounting bracket and a durable compact microphone
that doesn't require a ground connection, making
installation fast and easy. Also, the internal
speaker's position can be changed 180 degrees
by inverting the front panel.
- Die-cast chassis/heatsink and rugged
design that meets tough MIL-STD 810 C,
D & E specifications for shock, vibration
and dust means that you will have reliable performance
and sustained return on your investment for many
years. The rugged, easy-to-use microphone has
been newly designed with a telephone-style connector
and heavy-duty cable to protect against failure.
- The high-performance transceiver
design means the TK-768(H)/868(H) are equally
suited to urban, suburban and rural environments.
Built-in QT squelch segregates talk groups
so users only hear traffic from other co-channel
users in their own group. This reduces user misunderstandings
and confusion.
- DTMF encode/decode signaling
is also built-in creating a simple, inexpensive
"selective call" paging for fleets of
any size (10 digit codes, millions of combinations).
It can be used to privately call individual mobiles
within a fleet and also provide an alert output
to trigger a vehicle horn, headlights, or strobe
bar. Also, it is capable of displaying up to 5
characters of receiving signal status on the LCD.
- Voice encryption-ready: whether
protecting sensitive information or eliminating
dispatch "pirates", electronic eavesdropping
can be made virtually impossible by using many
of the encryption or voice scrambler devices available.
The TK-768/868 series mobiles have connection
provisions specifically made to accommodate any
of these devices.
- Programmable time-out timer cuts
off transmissions beyond an adjustable limit preventing
accidental keyups and overlong communications.
Busy channel lock-out prevents users from transmitting
on channels already in use.
- Programmable/assignable keys
provide one-touch control over radio functions
such as the home channel function. All are customizable
by your technician. A high-quality speaker with
4-watt amplifier delivers loud, clear audio output.
The rotatable front panel is design-engineered
to the operator's ergonomic requirements, providing
the optimum in safety and operating ease. Volume
and channel controls are up/down switches instead
of traditional knobs, and the large LCD display
is easily viewed from any angle.
