Features

Your RadioShack BTX-128 CTC-

SS•VHF Business Band Trans-

ceiver is a portable, two-way

business radio service transceiver

that you can carry almost any-

where. The transceiver is com-

pact and light, making it an ideal

choice for your business needs.

Your transceiver has these fea-

tures:

38-Tone CTCSS (Continuous

Tone Control Squelch System) —

helps reduce interference from

other transceivers which are oper-

ating on the same frequency and

in the same area.

Built-in VOX — allows hands-free

operation of your transceiver us-

ing an optional headset and mi-

crophone.

Programmable Frequencies —

you can program the transceiver

to any VHF business band fre-

quency you have a license to use

— no crystals to buy!

Rechargeable Battery Pack and

Battery Charger — the supplied

battery charger lets you conve-

niently recharge your transceiv-

er’s battery pack while it is on the

transceiver.

Earphone/Speaker and External

Microphone Jacks — let you con-

nect an external earphone or

speaker and an external micro-

phone for clearer communica-

tions in noisy areas.

Battery Low Indication — the

transceiver beeps when the bat-

tery pack is low.

Flexible Antenna — provides ex-

cellent reception.

Belt Clip — lets you attach the

transceiver to your belt or waist-

band.

ate this transceiver. Unless you

are already licensed to operate on

one of the preset frequencies, you

must apply for a frequency

through the PCIA (Personal Com-

munication Industry Association),

a non-profit organization that as-

signs frequencies nationwide to

help prevent conflicts between dif-

ferent businesses using transceiv-

ers in the same area. For more

FCC Part 90 Rules

You must be familiar with Part 90

of FCC Rules before you operate

your transceiver. The operation

instructions in this manual con-

form to Part 90, but do not cover

all items in Part 90.

19-1217.fm Page 5 Tuesday, August 3, 1999 1:18 PM

Overall, Part 90 states that:

• You must have a valid license

before you use the trans-

ceiver.

• As licensee, you are respon-

sible for proper operation of

all transceivers operating

under your license authority.

• You can let unlicensed per-

sons operate this transmitter,

as long as you take precau-

tions to prevent unauthorized

transmissions.

• You must use this transceiver

only for the commercial use

of your business, and only

when other commercial chan-

nels (such as the telephone)

are either not available or not

practical.

• You must always yield the

operating frequency to com-

munications that involve the

safety of life or property.

• You must take reasonable

precautions to prevent harm-

ful interference to other ser-

vices operating on the same

frequency.

• You must not transmit pro-

gram material of any kind

used in connection with com-

mercial broadcasting.

• You must not provide a ser-

vice that is normally handled

by telephone or telegraph

unless such broadcasts

involve the safety of life or

property or in emergencies

such as an earthquake, hur-

ricane, flood or a similar

disaster where normal com-

munication channels are dis-

rupted.

• During each transmission or

exchange of transmissions,

you must identify your sta-

tion with the call sign issued

to you by the FCC, or once

each 15 minutes during peri-

ods of continuous operation.

• You must keep a written

record of any maintenance

or modification made to the

transceiver, and you must

make this record available

for inspection upon demand

by the FCC.

Violating any of the provisions of

Part 90 can result in fines and/or

confiscation of equipment.

19-1217.fm Page 6 Tuesday, August 3, 1999 1:18 PM

Your transceiver might cause TV

or radio interference even when it

is operating properly. To deter-

mine whether your transceiver is

causing the interference, turn off

your transceiver. If the interfer-

ence goes away, your transceiver

is causing it. Try to eliminate the

interference by:

• moving your transceiver

away from the receiver

• contacting your local

RadioShack store for help

If you cannot eliminate the inter-

ference, the FCC requires that

you stop using your transceiver.

Additional FCC Regulations

The Business Radio Service is

under the jurisdiction of the

(FCC). Any adjustments or alter-

ations that would alter the perfor-

mance of the transceiver so it no

longer meets the original FCC

type acceptance or would change

the frequency-determining meth-

od are strictly prohibited.

Replacement or substitution of

crystals, transistors, ICs, regulator

diodes, or any other component

that is of a unique nature with

components other than those rec-

ommended can violate the techni-

cal regulations of the FCC rules or

violate type acceptance require-

ments of the rules.

Before you operate the transceiv-

er, you must obtain your license. It

is illegal to transmit without the

appropriate license, which you

can get by submitting a complet-

ed FCC Form 600 to the FCC (or

through the PCIA). Furthermore,

you are required to understand

Part 90 of the FCC Rules and

Regulations prior to operating

your transceiver. It is the user’s

responsibility to see that this unit

is operating at all times in accor-

dance with the FCC Rules and

Regulations.

Exposure to Radio Frequency

Energy

The design of your radio, which

generates radio frequency (RF)

electromagnetic energy, complies

with the following national and in-

ternational standards and guide-

lines:

GHz (EME - Electromagnetic

Fields)

To assure optimal radio perfor-

mance and to ensure that expo-

sure to RF energy is within the

guidelines in these standards, the

following operating procedures

should be observed:

For hand-held operation: The ra-

dio should be held in a vertical

position with the microphone one

to two inches away from the

mouth, and the antenna should

be kept one to two inches from

the head or body when transmit-

ting.

For body-worn operation: The an-

tenna should be kept at least one

inch from the body when trans-

mitting.

ElectromagneticInterference/

Compatibility

Nearly every electronic device is

susceptible to electromagnetic in-

terference (EMI) if inadequately

shielded, de-signed, or other-

wise configured for electromag-

netic compatibility.

Turn your radio off in any facilities

where posted notices instruct you

to do so. Hospitals or health care

facilities

19-1217.fm Page 8 Tuesday, August 3, 1999 1:18 PM

may be using equipment that is

sensitive to external RF energy.

Turn your radio off when on board

aircraft when instructed to do so.

Any use of the radio must be in

accordance with airline regula-

tions or crew instructions.

WARNING

Potentially Explosive

Atmospheres

Turn your radio off when in any

area with a potentially explosive

atmosphere, unless it is a type es-

pecially qualified for such use (for

example, FMRC Approved).

Sparks in such areas could cause

an explosion or fire resulting in

bodily injury or even death.

Do not replace or charge batteries

in a hazardous atmosphere. Con-

tact sparking may occur while in-

stalling or removing batteries and

cause an explosion.

Areas with potentially explosive

atmospheres are often, but not al-

ways, clearly marked. They in-

clude fueling areas such as below

deck on boats, fuel or chemical

transfer or storage facilities, areas

where the air contains chemicals

or particles such as grain, dust, or

metal powders, and any other

area where you would normally

be advised to turn off your vehi-

cle’s engine.

Blasting Caps and Areas

To avoid possible interference

with blasting operations, turn

your radio off near electrical

blasting caps or in a ‘blasting ar-

ea’ or in areas posted “Turn Off

Two-Way Radio.” Obey all signs

and instructions.

For Vehicles With an Air Bag

An air bag inflates with great

force. Do not place objects, in-

cluding portable or mobile two-

way radios, in the area over the

air bag or in the air bag deploy-

ment area. If improperly installed

or placed wireless equipment is

in the air bag deployment area

and the air bag inflates, serious

injury could result.

19-1217.fm Page 9 Tuesday, August 3, 1999 1:18 PM

Antennas

Do not use a radio with a dam-

aged antenna. If a damaged an-

tenna comes into contact with the

skin, a minor burn might result.

Batteries

All batteries can cause property

damage, injury, or burns if a con-

ductive material such as jewelry,

keys, or a beaded chain touches

exposed terminals. The material

may complete an electrical circuit

(short circuit) and become quite

hot. Exercise care in handling any

charged battery, particularly when

placing it inside a pocket, purse,

or other container with metal ob-

jects.

CAUTION

Chargers and Power Cord

To reduce risk of damage to the

supplied battery charger when

disconnecting it from AC power,

pull by the plug rather than the

power cord.

Make sure the power cord is lo-

cated so that it will not be stepped

on, tripped over, or otherwise sub-

jected to damage or stress.

Do not operate the charger with a

damaged cord or plug; replace

them immediately. Do not operate

the charger if it has received a

sharp blow, been dropped, or oth-

erwise damaged in any way; con-

tact your local RadioShack store.

Do not expose chargers to rain or

snow.

An extension cord should not be

used unless absolutely neces-

sary. Use of an improper exten-

sion cord may result in a fire or

electric shock. However, if an ex-

tension cord is used, make sure

that:

• The pins and plug of the

extension cord are the same

number, size, and shape as

those on the plug of the

charger.

• The extension cord is prop-

erly wired and in good condi-

tion.

• The cord size is 18 AWG for

lengths of up to 100 feet,

and 15 AWG for lengths up

to 150 feet.
