OPERATING FEATURES
1. Operation Features
The TK-380 is a UHF FM Radio designed in both 5tone
Model and DTMF/2tone/DMS Model. The programmable
features are summarized.
This transceiver can handle up to 250 groups with 250
channels in each group.

5Tone
Basic
Full
Full (Special Setting)
DTMF/2tone/DMS
1-1. 5tone Model
In this model, you can program Basic or Full level features.
When you select Basic level, only 1frame 5tone can be
programmed, and various functions are limited.
When you select "Special setting" in the Full Level, you can
use Encode/Decode format. Using Encode/Decode format, you
can further program the transceiver to run the script.
1-2. DTMF/2tone/DMS Model
You can use Option signalling which is DTMF or 2tone(only
for Decode) or DMS(Digital Message System -FFSK signalling)
for every channel.
2. Transceiver Controls and Indicators
2-1. Physical Layout
Note: The transceiver is also available without the DTMF
keypad (-).
2-2. Panel controls
The key on the top and front panel is momentary-type push
buttons. The functions of these keys and knob are explained

After the group number (or channel number) reaches the
highest group number (or channel number), it goes back to
lowest group number (or channel number).
Group numbers (or channel numbers) not set are skipped.
Caution : The FPU (KPG-60D) allows selecting between
group selector and channel selector.
3 Volume/Power switch
Transceiver Power and Volume switch. Turn clockwise to
switch On the transceiver. Turn counterclockwise fully to
switch OFF the transceiver. Also adjusts the volume level.
When the power is switched off, all the parameters, such

battery voltage alert function.
0 A, B,
2 C, and D 3 key (Programmable)
- DTMF keypad (keypad model only)
