A Little Sto About Walkie-Talkies
Once upon a time, people could only send messages by writing letters or
shouting loudly. Then, scientists discovered an "invisible magic wave"—Radio
Waves! These waves could travel quickly through the air and car sound over
long distances.
In the 20th centu, people invented walkie-talkies. The earliest walkie-talkies
were huge, like a brick, and could only be used by the milita or police. As
technology improved, walkie-talkies became smaller and more advanced, and
soon ordina people could use them to chat with friends. Today, you can
even build your own walkie-talkie and use it to communicate with your
buddies! How cool is that?
How Do Walkie-Talkies Work?
A walkie-talkie is like a "magic bridge."
1. When you speak: Your voice is captured by a small microphone and turned
into an electrical signal.
2. Electrical signal transformation: This signal rides on an "invisible fast
train"—radio waves—that quickly travels through the air.
3. Your friend's walkie-talkie receives it: The other walkie-talkie acts like a
catcher, grabbing the incoming radio waves and turning them back into
sound.
4. And then you can chat!
Isn't it amazing? These invisible and untouchable “waves” can actually car
sound ying back and foh!
A Brief Guide to Walkie-Talkies
A
Interesting Trivia
A walkie-talkie is like a superhero's "instant megaphone”—no need for SIM
cards or internet!
Radio waves travel incredibly fast, almost as fast as light!
But here’s a little secret about walkie-talkies: Only one person can speak at a
time; the other must remain silent, or else their voices will clash.
may result in accidental contact of positive/negative poles).
5."Modication by feel" is prohibited: Do not replace the original kit pas
(such as mismatched batteries, wires, etc.), or subtract/add components
(such as leaving out insulating pads). This may damage circuit stability and
cause overheating or leakage risks.
6.Guide children to recognize positive/negative poles (“+/-” signs on both
circuit board and batte). Wrong installation can burn the circuit board.
7.Remind children not to put small pas in their mouth throughout assembly:
especially screws and small buttons. If the child tends to bite objects, they
may wear child gloves during assembly (to avoid accidental picking up and
placing).
8.Handle metal pas carefully: Circuit board pins or batte electrodes may
scratch. If burrs are present, parents should use sandpaper to gently smooth
them out before handing pas to children.
Batte Precautions
● Turn o the walkie-talkie before replacing the batte. Install correctly
according to the “+/-” polarity marks in the compament. Do not install in
reverse.
● After installation, secure the batte cover with screws to prevent children
from accidentally opening the batte compament to access the batteries
during use.
● Replace the batte immediately if you nd the batte shell bulging,
deformation, leakage, electrode rusting, or if transmission/reception becomes
unstable during use. Dispose of used batteries properly.
● If the walkie-talkie will not be used for more than 1 month, remove the
batte to prevent leakage from damaging the circuit.
● Do not disassemble the batte compament. Do not touch the batte
terminals with metal objects (such as keys or coins) to avoid sho circuits.
WARNING! Please assemble under adult supeision.

metal pins or plastic burrs). If any pa is damaged (such as batte leakage,
cracked circuit board), stop using it immediately.
2.Store small pas safely: Place screws, batteries, and small buttons in a
dedicated storage box to prevent children from misplacing or swallowing
them.
3.Choose a at and open area for assembly: Clear the table of clutter
(especially cups, food, or metal objects), and place an insulating pad (such as
plastic mat or cardboard) to avoid sho circuits caused by contact with
conductive pas.
4.Parents read instructions rst: Understand the “pa relationships” and
“assembly sequence” before guiding children step by step. Incorrect order
may cause sho circuits (e.g., installing the batte before the circuit board

Disposal
The crossed-out wheeled-bin symbol on your product, literature,
or packaging reminds you that all electrical and electronic

collection locations at the end of their working life. Do not dispose
of these products as unsoed municipal waste. Dispose of them
according to the laws and rules in your area.
RF Safety
This two-way radio uses electromagnetic energy in the radio frequency (RF)
spectrum to provide communications between two or more users over a
distance. RF energy, which when used improperly, can cause biological
damage. Please refer to the following websites for more information on what
RF energy exposure is and how to control your exposure to assure
compliance with established RF exposure limits: http://www.who.int/en/
Keeping the radio at a proper distance is impoant as RF exposure decreases
with increasing distance from the proper antenna. Transmit no more than the
rated duty factor 50% of the time. Transmitting necessa information or less,
is impoant because the radio generates measurable RF energy exposure
only when transmitting in terms of measuring for standards compliance. For
users who wish to fuher reduce their exposure, some eective measures to
reduce RF exposure include:
- Reduce the amount of time spent using your wireless device.
- Use a speakerphone, earpiece, headset, or other hands-free accesso to
reduce proximity to the head (and thus head exposure). While wired
earpieces may conduct some energy to the head and wireless earpieces also
emit a small amount of RF energy, both wired and wireless earpieces remove
the greatest source of RF energy (handheld device) from proximity to the
head and thus can greatly reduce total exposure to the head.
- Increase the distance between wireless devices and your body.
This radio is designed for and classied as “General population/uncontrolled
use”. General population/uncontrolled environments are dened as locations
where there is exposure of individuals who have no knowledge or control of
RF exposure level.
Hand-held Mode
To control your exposure and ensure compliance with the uncontrolled
environment exposure limits, always adhere to the following procedure:
-To receive calls, release the PTT button.
-To transmit (talk), press the Push-to-Talk (PTT) button in
front of the face.
-Hold the radio in a veical position with the microphone
(and other pas of the radio including the antenna) at least
one inch (2.5 centimeters) away from the nose or lips.
Electromagnetic Inteerence/Compatibility
Nearly eve electronic device is susceptible to electromagnetic inteerence
(EMI) if inadequately shielded, designed, or otherwise congured for
electromagnetic compatibility. During transmissions, your radio generates RF
energy that can possibly cause inteerence with other devices or systems. To
avoid such inteerence, turn o the radio in areas where signs are posted to
do so, such as hospitals or healthcare facilities.
Persons with pacemakers, implantable cardioveer debrillators (ICDs) or
other active implantable medical devices should
- Consult with their physicians regarding the potential risk of inteerence
from radio frequency transmitters, such as poable radios (poorly shielded
medical devices may be more susceptible to inteerence).
- Turn the radio OFF immediately if there is any reason to suspect that
inteerence is taking place.
- Do not car the radio in a chest pocket or near the implantation site, and
car or use the radio on the opposite side of the body from the implantable
device to minimize the potential for inteerence.
Hearing Aids: Some digital wireless radios may inteere with some hearing
aids. In the event of such inteerence, you may want to consult your hearing
aid manufacturer to discuss alternatives.
Other Medical Devices: If you use any other personal medical device, consult
the manufacturer of your device to determine if it is adequately shielded
from RF energy. Your physician may be able to assist you in obtaining this
information.
ly shielded medical devices may be more susceptible to inteerence).
Protect your hearing
- Use the lowest volume necessa to do your job. Turn up the volume only if
you are in noisy surroundings.
- Limit the amount of time you use headsets or earpieces at
high volume.
- When using the radio without a headset or earpiece, do
not place the radio's speaker directly against your ear.
- Use carefully with the earphone maybe possible excessive
sound pressure from earphones and headphones can cause hearing loss.
CAUTION: Exposure to loud noises from any source for extended periods of
time may temporarily or permanently aect your hearing. The louder the
radio's volume, the less time is required before your hearing could be
aected. Hearing damage from loud noise is sometimes undetectable at rst
and can have a cumulative eect.
Batteries Safety
- Turn o your radio before removing or installing a batte. Store spare
batteries securely. Dispose of used batteries immediately and safely.
- Non-rechargeable batteries are not to be recharged
- Do not mix alkaline, standard (carbon-zinc) or rechargeable (Ni-Cd; Ni-MH)
batteries.
- Dierent types of batteries or new and used batteries are not to be
mixed.Do not mix batteries of dierent manufacturers, capacities, or sizes.
-Do not mix alkaline, standard (carbon-zinc) or rechargeable (Ni-Cd; Ni-MH)
batteries.
- Batteries are to be inseed with the correct polarity.Replacement of a
batte with an incorrect type can defeat the safeguard.
- Exhausted batteries are to be removed from the toy.
- The supply terminals are not to be sho-circuit.
- Rechargeable batteries are to be removed from the toy before being
charged
- Rechargeable batteries are only to be charged under adult supeision
- In the event of a batte leaking, do not allow the liquid to come into
contact with the skin or eyes. If contact has been made, wash the aected
area with copious amounts of water and seek medical advice immediately.
-If the batte compament (if applicable) does not close securely, stop
using the product and keep it away from children;
- Never put batteries in mouth. Swallowing may lead to serious inju or
death. If you think batteries might have been swallowed or otherwise placed
inside any pa of the body, please seek immediate medical attention and
contact the local poison control center.
- Do not dismantle, open or shred batteries. Batteries should be dismantled
only by trained people. •Disposal of a batte into re, or a hot oven, or
mechanically crushing or cutting of a batte, that can result in explosion;
