radio. You should fully charge the battery for optimal performance.
The GA-2S is a cost effective UHF-FM analog radio. It can communicate with any
other brand of radio that is UHF-FM analog, but without spending an exorbitant
amount of cash! You just need to make sure they are in the same channels/frequen-
cies, and this can be simply checked by using the software. If they are not in the
same frequency, just program via computer. (See chapter 4)
1. Scan Function
When the radio is allowed to be scanned, which can be set by the software, you can
press the Monitor key to turn on or turn off the scan. When the scan begins the

which is defined as scan added. When there is signal in the scanning channel, it will
stop in that channel.
NOTE
Please note that scan is only available when there are two or more than two
memory channels and two or more scan added channels.

be higher, the corresponding communication range will be further, but the anti-in-
terference ability will be weaker.
The default setting of squelch level is 5. You can adjust it through the menu
"Squelch Level” in the software from level 0 to 9, and 0 is the lowest level.

9. Time-Out-Timer (TOT)
This feature provides a safety switch that limits transmission time to a programmed
value. This will promote battery conservation by not allowing you to make exces-
sively long transmissions, and in the event of a stuck PTT switch it can prevent
interference to other users as well as battery depletion. If the transmitting time
exceeds the TOT pre-set time, a beep will be heard and the radio will stop transmit-
ting.

Appendix A -- RF Energy Exposure and Product
Safety Guide for Portable Two- way Radios
ATTENTION!
Before using this radio, read this guide which contains important operating instruc-
tions for safe usage and RF energy awareness and control for compliance with
applicable standards and regulations.
This two-way radio uses electromagnetic energy in the radio frequency (RF)
spectrum to provide communications between two or more users over a distance. It
uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy
is one form of electromagnetic energy. Other forms include, but are not limited to,
sunlight and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which when used improperly, can cause biological
damage. Very high levels of x-rays, for example, can damage tissues and genetic
material.

Experts in science, engineering, medicine, health, and industry work with organiza-
tions to develop standards for safe exposure to RF energy. These standards provide
recommended levels of exposure for both workers and the general public. These
recommended RF exposure levels include substantial margins of protection.
All Radioddity two-way radios are designed, manufactured, and tested to ensure
they meet government established RF exposure levels. In addition, manufacturers
also recommend specific operating instructions to users of two-way radios. These
instructions are important because they inform users about RF energy exposure and
provide simple procedures on how to control it.
Please refer to the following websites for more information on what RF energy
exposure how to control your exposure to assure compliance with established RF
exposure limits:

Radio License
Governments keep the radios in classification, most of the classified walkie-talkie
need to get local government License and operation is allowed. For the following
specified classification: the USA FRS. Australian CB, the individual license is not
required.

RF energy exposure standards and guidelines (if appropriate)
Your Radioddity two way radio complies with the following RF energy exposure
standards and guidelines:
1.United States Federal Communications Commission(FCC), Code of Federal Regula-
tions; 47 CFR part 2 sub-part J
2.American National Standards Institute(ANSI)institute of Electrical Electronic
Engineers (IEEE)c95.1-2005
3.IEEE Std. 1528: 2013 and KDB447498, Evaluating Compliance with FCC Guidelines
for Human Exposure to Radio Frequency Electromagnetic Fields
4.Institute of Electrical and Electronic Engineers (IEEE)C953-2002
5.International Commission on Non-lonizing Radiation Protection (ICNIRP)
6.Ministry of Health (Canada) Safety Code 68: Industry Canada RSS-102
7.International Electrotechnical Com-mission IEC62209-2. 2010

Operating Instructions
1.Transmit no more than the rated duty factor of 50% of the time. To Transmit
(Talk), push the Push To Talk (PTT) button to receive calls(listen), release the PTT
button. Transmitting 50% of the time, or less, is important because the radio
generates measurable RF energy exposure only when transmitting in terms of
measuring for standards compliance.
2. Transmit only when people outside the vehicle are at least the recommended
minimum lateral distance away from a properly installed according to installation
instructions, externally mounted antenna.
3.When operating in front of the face, worn on the body, always place the radio ina
Radioddity approved clip, holder, holster, case, or body harness for this product.
Using approved body worn accessories is important because the use of Non-Radi-
oddity approved accessories may result in exposure levels, which exceed the
IEEE/ICNIRP occupational/controlled environment RF exposure limits.
4.1f you are not using a body worn accessory and are not using the radio in the
intended use position, in front of the face or at the body in the PTT mode or
alongside of the head in the phone mode, then ensure the antenna and the radio
are kept 2.5 cm (one inch) from the body when transmitting. Keeping the radio at
a proper distance is important because RF exposures decrease with increasing
distance from the antenna.

Protect your hearing
1.Use the lowest volume necessary to do your job.
2.Turn up the volume only if you are in noisy surroundings.
3.Turn down the volume before adding headset or earpiece.
4.Limit the amount of time you use headsets or earpieces at high volume.
5.When using the radio without a headset or earpiece, do not place the radio's
speaker directly against your ear.
Note: Exposure to loud noises from any source for extended periods of time may
temporarily or permanently affect your hearing. The louder the radio's volume, the
less time is required before your hearing could be affected.
Hearing damage from loud noise is sometimes undetectable at first and can have a
cumulative effect.
Safety Operation
Forbidden
1.Do not use charger outdoors or in moist environments, use only in dry
locations/conditions.
2.Do not disassemble the charger, which may result in risk of electrical shock or fire.
3.Do not operate the charger if it has been broken or damaged in any way.
4.Do not place a portable radio in the area over an air bag or in the air bag deploy-
ment area. The radio may be propelled with great force and cause serious injury
to occupants of the vehicle when the air bag inflates.

To reduce risk
1.Pull by the plug rather than the cord when disconnecting the charger.
2.Unplug the charger from the AC outlet before attempting any maintenance or
cleaning.
3.Contact Radioddity for assistance regarding repairs and service.
Use of Communication Devices While Driving
1.Always check the laws and regulations on the use of radios in the countries and
areas where you drive.
2.Give your full attention to driving and to the road.
3.If available, use the hands-free facility.
4.1f driving conditions or regulations require it, pull off the road and park before
making or answeringa call.
