TABLE OF CONTENTS
This is a highly versatile, yet compact hand-held transceiver
that is built and tested to stringent specifications. The
following features are built into your Transceiver.
☆ Smallest and lightest transceiver in this class.
Dimensions: 83.5mm (height)x55mm(width)x31mm(depth)
(excluding protrusions and battery case).
Weight: 185g (excluding battery case and antenna)
☆ Paging function is available when an optional DTMF is
installed. This feature allows you to page one specific
station or all group stations via a 3-figured DTMF signal.
When a paging signal is received, a beep sound and the
display will inform you that someone has you paged. The
paging station can be identified by means of its individual
code.
☆ Code Squelch operation is available with when an optional
DTMF is installed. The Transceiver will hear only stations
using the identical code.
☆ Tone Squelch operation is available with an optional
CTCSS. The Radio will hear only stations using the
specific tone frequency. Tone frequencies can be selected
via the rotary channel selector.
☆ DTMF and CTCSS can used together.
☆ An optional High Power Rechargeable Battery Pack or an
external power supply of 13.8V enable powerful
transmission.
☆ A wide range of acceptable external power supply
voltages (5 to 16V DC) allows you to power it from an
automobile battery.
☆ High Sensitivity.
☆ Up to 40 memory channels are available.
☆ Independent tone frequencies and offset frequencies can
be programmed in any memory.
☆ Internal Dual-Watch allows the Transceiver to watch.
• the selected dial-frequency and the stored frequency in
memory address Ml;
• the selected dial-frequency and any other memory
frequency
• the selected dial-frequency and each memory frequency
under scanning in sequence, (up to 40 channels)
• the selected dial-frequency and call frequency
☆ Either Pause or Busy scan functions can be selected.
Scanning the dial-frequency provides a VFO full band
scan. Scanning of a memory frequency provides all
memories scan.
☆ A single pushbutton press opens the squelch so you can
easily check the volume setting.
☆ A Battery-Save function allows you to reduce the current
drain during receiver standby.
OPTIONAL ACCESSORIES
☆ An Auto-Power Off function reduces the current drain if you
forget to turn the transceiver off. DTF145
☆ Frequencies can be entered directly from the keyboard or RBP072
via a rotary channel selector. RBP120
☆ A Function button allows you to change the frequency with SOOmAh)
a 1 MHz step when you turn the rotary channel selector. CHA072
☆ Selected frequencies and operating mode may be locked CHA120
to prevent inadvertent key operation. PCA145

CONTROLS AND CONNECTIONS
®
© Power On-OFF SwitchA^olume Control
This is to turn the power on and off and to control the
volume. Rotate the control clockwise to turn the power
on,and rotate it clockwise further to increase the volume.
The Squelch Off button should be held depressed or the
Squelch Control rotated fully counterclockwise while
controlling the volume.
© Squelch Control
This is to control white noise. Rotate it clockwise slowly
and set the control where the noise stops.
NOTE:
(1) DO not rotate the control clockwise too far.
(2) The control should be placed where the white noise is not
heard during following operations; Scanning, Dual-Watch,
Battery-Save, Paging and Code Squelch.
(3) Adjust the control with the channel which is not receiving
the signal.
© Rotary Channel Selector
This is to select the transmit/receive frequency. It is also
used to change the tone frequency, channel step and
memory address number. Rotate the selector clockwise
to increase the frequency and counterclockwise to lower
it. The interval by which the frequency changes is referred
to as "Channel Step". The Channel Step which is
initially set to 10kHz can be changed to 5, 12.5, 20, 25 or
50kHz. (Refer to Changing the Channel Step, contents 14).
0 External Speaker Jack: S

a) Hold the Transceiver and place your thumb on the
Lock button.
b) Push up the Lock Button and pull the battery case as
illustrated to clear the lock.
c) Pull the battery case further and remove it from the
Transceiver.
10
If you are using the battery pack for 6 AA battery, insert
3
size AA batteries into the battery pack. Be sure that the
batteries are inserted with correct polarity.
NOTE:
Apply the new batteries only.

Attach the battery to the Transceiver. Engage the battery
on the slot of the bottom of the Transceiver and push the
battery case until it latches in the proper position.
■ Turn the power switch on and set the volume control to a
5
comfortable listening level.
Rotate the squelch control clockwise slowly until the
6
noise from the speaker stops.
NOTE:
Do not rotate the control clockwise too far. Excessive
squelch reduces the radio sensitivity and may prevent
reception.

1 Setting an Operating Frequency
0 With a rotary channel selector
You can change the operating (transmit and/or receive)
frequency by rotating the rotary channel selector. As the
selector rotated, the displayed frequency changes in
10kHz steps. It changes in 1MHz steps when rotated with
the function button held depressed.
( Procedure)
Rotate the rotary channel selector clockwise to increase the
displayed frequency and counter clockwise to decrease it.
• Although the channel step is initially set to 10kHz at the
factory,you may use any one of six options, 5, 10,12.5, 20,
25 and 50kHz. How to select the channel step is outlined
under "Changing the Channel Step”, contents.
0 With buttons on the front panel
You can change the operating frequency with numeral
buttons of “0” to “9”.
( Procedure )
Example:To set 145.80MHz
a) a 10MHz figure
b) a MHz figure......................press”5”
c) a 100kHz figure.................press”8”
d) a 10kHz figure
..................
..................
press”4”
[14] will be displayed.
[145] will be displayed.
[145.8] will be displayed.
press”0”
[145.80] will be displayed.
(information)
• The frequency step rate as the selector rotated is referred
to as a channel step.
14
When four numeral buttons are pressed correctly, a long
beep tone will be generated informing you that frequency
setting is complete.
(information)
If you want to cancel the setting in the middle of the
operation, press the */MR /ENT button. The display will return
to the previous frequency.
This is called the dial-frequency mode.
Expanding the receive frequency:
For receiving 130-170 MHz.
( Procedure )
1. Turn power off.
2. Press [3]+[CALL] while turning power back on.
(information)
Returning the receiving range to normal:
CAUTION! This resets the radio and erases all memories.
Press [FUNC]+[CALL] while turning power back on.
15
Changing the memory to the 40 channel mode
This function changes the memory size from 20 to 40
channels. Turn off the radio. Press and hold [CALL] and [6] at
the same time. Turn on the radio.
/ U C D ~i I
I I L U I
Note: “6" is display. Turn radio off, then back on. Normal
display returns. Call channel can not be changed
while in 40 channel mode. If you wish to use the call
channel in 40 channel mode, you must program it
before you put the radio in 40 channel mode.
Programming Frequency in
Memory [*/MR/ENT Button]
Up to 40 memories may be programmed. They are saved
under the addresses 0 through 39 (in 40 channel mode) or 0
through 9 and 0 through 9 (in 20 channel mode).
( Procedure)
(When the memory is vacant)
1. Select VFO mode (no “M” in display)
2. Input frequency, tone, and offset (if needed) and press
[MR/ENT]
3. Select memory 0-9, 0-9, or 0-39 by rotating dial knob.
4. Hold [FUNC] and press [MR/ENT] to store the memory. A
long beep tone notifies you that the operation is complete.

@ Example: To recall the memory frequency
successively
Keep the Transceiver in the memory mode. Press the

desired address number. The stored frequency under the
address number will be displayed.
(information)
• In 20 channel mode the numeral button can only recall
the address number within either M or M memory groups.
When the recalled address number is vacant (i.e. no
frequency is stored), “M” on the display will flash and the
dial-frequency will be indicated.
The */ MR /ENT button switches the dial-mode and
