TK-278/378 in
detail:
Large LCD display provides clear
legibility under any lighting conditions from bright sunshine to the dark of
night (backlight on). It also displays various icons showing current operating
status.
Tough, lightweight and compact
construction means the TK-278/378 will provide long-lasting field life. And
because they meet U.S. MIL-STD 810 C/D/E standards covering shock, vibration,
humidity, dust, and rain, they will perform in even the toughest conditions.
The vertical layered design, with the
battery pack forming the entire back of the unit and the transceiver components
forming the front, is a fresh departure from the conventional stacked design.
This approach results in a stronger chassis and a single PCB, and improves the
overall styling and appearance of the radio.
32-channel capacity (semi-duplex) ensures
plenty of room for applications today and tomorrow. And once programmed, users
simply select channels with the convenient rotary encoder located on the top of
the radio.
Busy channel lockout further improves
channel management by preventing transmit if another talk group is already on
the air.
A time-out timer limits the transmission
time of the radio. Settings include the time allowed for continuous transmit,
the period before the TOT alarm sounds, and the retransmit prohibit period and
associated time allowed for temporary receive. These help guard against misuse
or accidental key-ups.
Built-in QT signaling segregates talk
groups so users only hear traffic from other co-channel users in their own
group. Selectable QT means the user can temporarily change the QT frequency set
for each channel.
DTMF signaling adds another dimension to
paging with 3- to 10-digit DTMF code combinations available. 3-digit ID plus
1-digit group code Sel Call, and a 1- to 5-digit status code are also
supported, as is DTMF group calling.
Two types of ANI -- PTT ID and DIAL ID --
send connect and disconnect ID information. PTT ID is activated by the PTT, and
DIAL ID by the dial keys. It is also possible to individually set PTT ID as on
or off for each channel.
Monitor/Squelch OFF defeats the preset
signaling mode, or allows the squelch to be opened manually for receiving weak
signals.
Call alert lets you know you were called
with DTMF signaling.
DTMF transpond transmits a code telling
the caller that your radio received their DTMF paging signal.
Signaling AND/OR logic works when using
combinations of signaling systems. Squelch is opened when either one, or all,
signal requirements are met, depending on your settings.
Convenient dialing functions include Manual
Dial, Auto-Dial, Redial and Store & Send (display shows the
input DTMF code before it is sent).
The power saver feature automatically
places the receiver in a "sleep" mode for short intervals during periods of
inactivity.
Low battery alert causes the red TX LED
to flash a warning when voltage drops below threshold.
Other Features:
| The dial key also functions
as a D/A key, allowing users to add or delete scan channels at any time to
customize the scan list for temporary assignments or to avoid nuisance
traffic. |
| The talk around key switches
the radio to simplex mode (non-repeater) for close-in communications. |
- Priority scan
- 500 mW speaker audio output
- Built-in speaker mic jack
- Space for optional signaling
boards
- AUX switch turns its function on and
off.
