or above each button.
To activate certain transceiver features, you must press F (function) and another button at the same time.
Those key combination instructions are printed as the first button name, +, then the second button name. For
example, F+ TOT means hold down F while you press TOT.
Button names are printed in small, bold, capital letters such as CLR or MR. Words, symbols, and numbers
that appear on the display are printed using a distinctive typeface, such as 146.940 or MR.
FCC INFORMATION
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions : (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

INTRODUCTION TO AMATEUR RADIO
Your transceiver is the perfect first radio for anyone entering the exciting world of amateur radio, s well as a
great additional transceiver for the experienced amateur radio operator. Your transceiver opens a door for you
to the world from almost anywhere! All you need is an Amateur Radio Operator’s License (Technician Class
or higher) issued by the Federal Communications Commission (FCC). If you do not have a license, it is easier
than ever to get one, and help from licensed operators is available. Here are a few tips to help you get started.
You can turn on your transceiver and scan the entire band to hear what is going on; however, do not attempt to
transmit until you get your license. If you transmit without a license, you are in violation of federal law that
can lead to severe penalties. Note that ham operators take the FCC rules very seriously and want nothing to do
with “bootleggers” – their term for people who operate without a license.
Find out if there is a ham radio club in your area. Most clubs welcome new transmissions, write to the
American Radio Relay League (ARRL) at the following address to find out how to cntact a local affiliate. The
ARRL is the national organization representing amateur radio in the United States. The league has more than
150,000 members. Most are ham operators, or members in the process of obtaining their license.

Starting for the license exams. Do not be intimidated by the word “study” because most people can go from
knowing absolutely nothing about amateur radio to passing the Novice and Technician written exams in less
than a month.
The exams test your knowledge of basic radio regulations and elementary radio theory. Many clubs hold
license classes which can be a fun and easy way to learn about amateur radio. There are good books, cassette
tapes, computer programs, and many other study aids available. Your local RadioShack store sells FCC
License Preparation study guides for amateur radio operator licenses. While you are no longer required to
VERSION III
2001/2/28
BG TECH.
learn Morse code for a Technician Class license, we encourage you to learn it anyway so you can advance to
higher levels of operating privileges.
There is no fee to take the Novice exam. As soon as you pass the Novice exam, you can immediately take the
Technician exam. All license level tests are administered by a three-member Volunteer Examiner Team.
Contract the ARRL for a schedule of exam opportunities in your area.
The Technician Class license lets you use the transceiver to communicate directly with other operators, and
use repeaters for distant communication.
Amateur radio is a great hobby that has enriched the lives of millions of people all over the world. The ARRL
would be glad to hear from you if you need more information or would like to join!

PREPARATION
You can operate your transceiver from any of four power sources;
Li-Ion batteries
Alkaline batteries
AC Power (using an optional AC adapter)
Vehicle battery power (using an optional DC adapter)
USING INTERNAL BATTERIES
Using Rechargeable Batteries
You can power your transceiver using two lithium ion batteries supplied as a sealed pack.
The battery pack has a built-in circuit that lets you recharge Li-Ion batteries. To charge the batteries, connect
an supplied external AC to DC adapter to the battery pack’s CHG jack.
Caution) Please, clear the contact on the radio to the lithium ion battery pack with alcohol from time to time.
Testing Internal Batteries
To test the batteries, hold down PWR for about 1 second. The battery voltage briefly appears. The bars of
battery icon on LCD appears as a battery monitor indicator. There more bars in side the icon, the stronger the
batteries. When there are no bars in side of battery icon and flashes, recharge the battery or replace all the
batteries if Alkaline batteries are used as soon as possible.
Using Non-Rechargeable Batteries
You can power your transceiver using four alkaline batteries using alkaline battery.
USING AC POWER
You can power the transceiver using a 13.8V DC power supply with a size H Adapta-plug adapter. This is
available at your local RadioShack store.
USING VEHICLE BATTERY POWER
VERSION III
2001/2/28
BG TECH.
You can power the transceiver from a vehicle’s 13.8V power source or cigarette lighter socket using 13.8 V
DC to DC power adapter and a size H Adaptaplug (neither supplied). Both are available at your local
RadioShack store.
CONNECTING THE ANTENNA
Place the threaded base socket of the supplied antenna over the antenna connector on the top of the
transceiver and turn the antenna clockwise to tighten it. To remove it, turn it counterclockwise.
Caution : Do not over-tighten the antenna
Note : You can connect an external antenna to the transceiver using an SMA to BNC adapter. This adapter and
suitable antennas are available at your local RadioShack store.
ATTACHING THE BELT CLIP
Use the Philips screwdriver and the two supplied screws to attached the supplied belt clip to your transceiver.
Do not over-tighten the screws.
ATTACHING THE WRIST STRAP
To attach the supplied wrist strap to the top of the belt clip, thread the strap’s small loop through the opening
in the top of the clip. Then insert the longer loop through the smaller loop and pull on the strap until the loop
is tight.
CONNECTING A MICROHONE/SPEAKER
You can connect an external communications headset (consisting of a microphone and speaker) to the
transceiver so you can use it privately. Lift the hinged, rubber dust cover from the MIC and SPK jacks on top
of the transceiver. Then insert the plug of an optional voice activated headset with microphone, or an optional
communication headset, into the jacks.
Caution : Use only microphone and speaker accessories that do not share a common ground for the speaker
and microphone. Doing otherwise might damage the transceiver.
VERSION III
2001/2/28
BG TECH.
Note : Connecting a headset’s plug to the transceiver’s SPK jack automatically disconnects the internal
speaker.
You can also connect an optional mono earphone to the SPK jack. This lets you use the transceiver’s push-to
talk button to transmit as usual. Your local RadioShack store carries a wide selection of suitable
communication headsets, earphones, and separate components.

SYSTEM FEATURES
Your transceiver can transmit and receive a low-level, selectable, subaudible tone at the same time as it
transmits (TX) or receives(RX) a regular signal. This special tone lets you listen only to other radio set to the
same tone frequency when you use the transceiver in simplex operation. It also lets you match your radio to
the subaudible tone frequency used by a local repeater.

don’t receive in signal, it goes to scan in sub. If pressing PTT, it transmits in last memory channel
before entering the dual watch mode and dual watch is canceled.
If “M” key is held down, it scans in sub frequency till "M" is released. If released “M” key, it waits
200 msec in main channel and back to the sub frequency.
The initial frequency in main and sub. is same.
RECEIVING AIR BAND
Select Air band frequency by pressing
and tune the frequency you want to hear pressing
or rotate Ch rotary switch. When the mode is air band, “A” appears on the top of LCD.
The air band RX range is 108.000 ~ 136.9875MHz.
