What’s in the box
This transceiver comes shipped with below items and accessories in the box:
Dual-band Radio
2200mAh Battery
Dual Band Antenna
Desktop Charger
Adapter
Earpiece Kit
Wrist Strap
Belt Clip
User manual
Assembly
Before the radio is ready for use we need to attach thew antenna and battery pack, as well as charge
the battery .
Antenna
This transceiver is fitted with a Male SMA connector. To mount your antenna (Female SMA connector),
align the two connectors and turn clockwise until it stops.
Notice
Please make sure to install the antenna and battery is charged when start using a radio.
Do not over-tighten your antenna to avoid damage to the outer materials and the connect base.
When installing the antenna, please remember to grip it by the base and screw.
When you choose using an external antenna, make sure its SWR is about 1.5:1 or lower to avoid
damage to the transceiver.
Do not hold the antenna with your hand or wrap the outside of it to avoid interference to the transceiver.
Never transmitting without an antenna.
Belt clip
There are two parallel screws mounted on rear radio body, remove them and thread through the holes
on the belt clip as you screw them back into the radio body.
Do not add any form of glue to fix the screws on the battery clip.
The solvents in the glue may cause damage to the battery casing.

05 06
Battery
Before attaching or removing the battery make sure your radio is turned off by turning the power/volume
knob all the way counter-clockwise.
Installation
Make sure the battery is aligned in parallel with the radio body with the lower edge of the battery about
1-2cm below the edge of the radio.
Once aligned with the guide-rails, slide the battery upward until you hear a click sound to lock the
battery in place.
Removal
To remove the battery, press “PUSH” buckle on the middle top (see Figure 2. 1,”Radioddity GA-510
Radio, overview”), as you slide the battery downward.
Charging and battery maintenance
Charging
Battery should be fully charged before initial use. Optimum battery efficiency will be achieved after the
three full battery charge and discharge cycles.
How to hook up and use the charger correctly:
1. Plug the DC connector of the power adaptor into the charger base.
2. Plug the AC connector of the power adaptor into an AC wall outlet.
3. Place the radio in the charging base.
4. Make sure the radio is making contact with the charger. When the red LED comes on steady, your
radio is charging.
5. The radio is fully charged once the charger’s green status LED goes steady. Please remove the radio
at that time to avoid over-charging.

The charger and battery are fitted with matching notches so that the battery can be charged individually!
That is very practical if you have two batteries, that you can charge one battery while still using your radio.
Radio should be POWERED OFF during charge cycle.

07 08
Battery Maintenance
The battery is provided without power from the factory; please let it charged for at least four to five
hours before you start using your radio.
Use only batteries approved by the original manufacturer.
Never attempt to disassemble your battery pack.
Do not expose your batteries to fire or intense heat
Dispose of batteries in accordance with local recycling regulations.
Prolonging your battery’s life
Only charging batteries in normal room temperatures.
When charging a battery attached to the radio, power off the radio for a faster charge.
Before the charging is completed, do not unplug the power to the charger or remove the battery.
Never charge or use a wet battery.
Batteries wear out over time. When the radio is operated in a shorter time, please consider
purchasing a new battery to replace.
Battery’s performance will be reduced in temperatures below Zero. When working in cold
environments, it is suggested to prepare a spare battery. Preferably inside your jacket or in a similar
location in order to keep the battery warm.
Dust can interfere with the connection between the battery and the radio. If necessary wipe the
contacts with a clean cloth to ensure proper contact with radio and charger.
If your battery has become wet, take it down from the radio, wipe it dry with a towel or soft tissue, and
put it in a plastic bag with a handful of dry rice. Tie the bag up and leave there overnight.
The rice will absorb any remaining moisture in the battery.
This method is only effective against minor splashes (light rain for instance). A soaked radio may
possibly be defective to use.
Storage
In order to prevent damage from over-discharge, the battery must be left with partial power. This radio
uses a lithium-based battery and a 40% charge is recommended. This level minimizes age-related
capacity loss while keeping the battery in operating condition and allowing self-discharge.

Chapter 3. - Basic Use Making a call
Press and hold the PTT button on the side of the radio body to transmit. While transmitting, speak
approximately 3-5cm from the microphone. When you release the PTT your transceiver will go back
to receive mode.
Channel selection
There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For daily use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode.
However, Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO)
mode is also used for programming channels into memory. For details on how to program your
transceiver see Chapter 9, Programming.
Ultimately which mode you end up using will depend entirely on your use case.
Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the [ ] and [ ] keys.
Each press will increment or decrement your frequency according to the frequency step you've set your
transceiver to. For details on how to set the frequency step on your transceiver see Chapter 4, Working
the menu system and the section called "1 STEP" in Appendix B, Menu definitions.
Power and volume
Before we turn the power on, make sure you have attached the battery and antenna as described in
Chapter 1, Initial setup.
Turning the unit on
To turn the unit on, simply rotate the volume/power knob clockwise until you hear a “click”. If your radio
powers on correctly there should be an audible double beep after about one second and the display
will show a message or flash the LCD depending on settings for about one second (see "35 PON
MSG - Power On Message" in Appendix B' Menu definitions). Then it will display a frequency or
channel. If the voice prompt is enabled, the voice will announce "frequency mode" or "channel mode”.
Turning the unit off
Turn the volume/power knob counter-clock wise all the way until you hear a "click". The radio is now off.
Adjusting the volume
To turn up the volume, turn the volume/power knob clock-wise.
To turn the volume down, turn the volume/power knob counter-clock-wise. Be careful not to turn it too
far, as you may inadvertently turn your radio off.
Just because you can program in a channel does not mean you're automatically authorized to
use that frequency.
Transmitting on frequencies you're not authorized to operate on is illegal, and in most
jurisdictions a serious offence. If you get caught transmitting without a license you can and will
get fined, and in worst case sent to jail.
However, it is legal in most jurisdictions to listen. Contact your local regulatory body for further
information on what laws, rules and regulations apply to your area.

Chapter 5. - Scanning
Radioddity GA-510 features a built-in scanner for the VHF and UHF bands. When in Frequency (VFO)
mode it will scan in steps according to your set frequency step. In Channel (MR) mode it will scan your
channels.
Scanning modes
The scanner is configurable to one of three ways of operation: Time, carrier or search, each of which
is explained in further details in their respective section below.
Procedure 5.1. Setting scanner mode
1. Press the [MENU] key to enter the menu.
2. Enter 1 and 8 on your numeric keypad to turn to scanner mode.
3. Press the [MENU] key to select.
4. Use the [▲] and [
▲
] keys to select scanning mode.
5. Press the [MENU] key to confirm and save.
6. Press the BACK key to exit the menu.
Time operation
In Time Operation mode, the scanner stops when it detects a signal, and after a factory pre- set time
out, it resumes scanning.
Carrier operation
In Carrier Operation mode, the scanner stops when it detects a signal, and after a factory preset time
with no signal it resumes scanning.
Search operation
In Search Operation mode, the scanner stops when it detects a signal.
To resume scanning you must press and hold the # key again.
Tone Scanning
Scanning for CTCSS and DCS Tones/Codes
CTCSS tone and DCS code scanning mode can be accessed with or without a signal being present.
The scanning process itself only occurs while signal is being received.
Not all repeaters require a CTCSS tone or DCS code for access will transmit one back. In that case,
the transmitter of a station that can access the repeater would need to be scanned. In other words:
this would be done by listening to stations on the repeater's input frequency.
Before setting CTCSS/DCS scanning, set the receiving frequency to ensure that the signal can be
received at the receiving frequency, and cancel the dual standby function, and make the radio work in
the frequency mode.
Scanning for CTCSS Tone
1. Press the [MENU] key to enter the menu.
2. Enter 2 and 8 on your numeric keypad to come to Menu 28: Scan CTCSS
3. Press the [MENU] key to begin CTCSS scanning.
4. CTCSS code keep changing to indicate that the radio is in CTCSS scanning mode. In this mode,
the lower display will cycle through the CTCSS tones as they are being tested. Once the frequency
of the received CTCSS tone is determined, the CTCSS tone will stop changing.
5. Press the BACK key to exit the menu.

6. Press the BACK key to exit the menu.
DTMF is an in-band signaling method using dual sinusoidal signals for any given code. Originally
developed for telephony systems, it has proved a very versatile tool in many other areas.
In two-way radio systems, DTMF is most commonly used for automation systems and remote control.
A common example would be in amateur radio repeaters where some repeaters are activated by
sending out a DTMF sequence (usually a simple single-digit sequence)
Table 7.1. DTMF frequencies and corresponding codes
Scanning for DCS Tone
1. Press the [MENU] key to enter the menu.
2. Enter 2 and 9 on your numeric keypad to come to Menu 29: Scan DCS
3. Press the [MENU] key to scan.
4. The DCS changes indicate that the machine has entered the DCS scanning status, then DCS
changes rapidly according to the standard sequence. When the radio finds that the DCS in the
receiving signal is consistent with one of the standard sets of DCS, the radio stops scanning and
receives the speech.
5. Press the BACK key to exit the menu.

Chapter 8 -Selective calling
Some times when you're working with larger groups of people using the same channel, communication
can get very crowded or disorderly. To minimize this problem, several methods of blocking out unwanted
transmissions on your frequency have developed. In general, there are two forms of selective calling
in two-way radio systems: Group calling, and individual calling.
Group calling, as the name suggest, is a one-to-many form of communication. Every radio in your
working group is configured the same way and any radio will make contact with every other radio in
the group.
Individual calling, sometimes also known as paging, is a one-to-one form of communication.
Every radio is programmed with a unique ID code. And only by sending out a matching code can you
get that radio to open up to your transmissions.
Radioddity GA-510 features three different ways of group calling
CTCSS
DCS
Tone-burst (1000Hz, 1450HZ, 1750Hz,2100Hz)
Radioddity GA-510 does not feature any form of individual calling
CTCSS and 1750Hz tone-burst are also popular methods among amateur radio operators to open up
repeaters.
CTCSS
CTCSS is set with menus 11 RX CTCSS and 13 TX-CTCSS.
For a complete list of available CTCSS codes and corresponding sub-tone frequencies, see Table C.2,
"CTCSS Frequencies" in Appendix C, Technical specifications.
Procedure 8. 1. CTCSS setup how-to
1. Press the [MENU] key to enter the menu.
2. Enter 1and 1 on the numeric keypad to get to receiver CTCSS.
3. Press [MENU] to select.
4. Enter desired CTCSS sub-tone frequency in hertz on the numeric keypad.
5. Press [MENU] to confirm and save.
6. Enter 1 and 3 son the numeric keypad to go to transmitter CTCSS.
7. Press [MENU] to select.
8. Enter desired CTCSS sub-tone frequency in hertz on the numeric keypad. Make sure it's the same
frequency as that you entered for receiver CTCSS.
9. Press [MENU] to confirm and save.
10. Press BACK to exit the menu system.
If you have the keypad lock enabled on your radio, you can still send DTMF tones the regular
way without having to unlock your radio.
Using these features does NOT mean that others won't be able to listen in on your transmissions.
They only provide a method to filter out unwanted incoming transmissions. Any communications
mode while using these features will still be heard by anyone not employing filtering options of
their own.
Also, you cannot change the CTCSS or DCS settings while in memory (MR) mode.

27 28
To turn CTCSS off, follow the same procedure but set it to off with the 0 key instead of selecting a
CTCSS sub-tone frequency.
For more operation details, see the section called"11- RX CTCSS" and the section called"13- TX CTCSS"
in Appendix B, Menu definitions.
DCS
DCS is set with menus 10 RX DCS and 12 TX DCS
For a complete list of available DCS codes, see Table C.1, "DCS Codes" in Appendix C,
Technical specifications.
Procedure 8. 2. DCS setup how-to
1. Press the [MENU] key to enter the menu.
2. Enter 1and 0 on the numeric keypad to get to receiver DCS.
3. Press [MENU] to select.

5. Press [MENU] to confirm and save.
6. Enter 1 and 2 on the numeric keypad to go to transmitter DCS.
7. Press [MENU] to select.
8. Enter desired DCS code on the numeric keypad. Make sure it's the same code as that you entered
for receiver DCS.
9. Press [MENU] to confirm and save.
10. Press BACK to exit the menu system.
To turn DCS off, follow the same procedure but set it to off with the 0 key instead of selecting a DCS
code.
For more operation details, see the section called"10 RX DCS" and the section called"12 TX DCS" in
Appendix B, Menu definitions.
Memory channels are an easy way to store commonly used frequencies so that they can easily be
retrieved at a later date.
Radioddity GA-510 features 128 memory channels that each can hold: Receive and transmit frequencies,
transmit power, group signaling information, bandwidth, ANI/ PTT-ID settings and a six-character
alphanumeric identifier or channel name 1.
Frequency Mode vs. Channel Mode
Switch between Modes by Using Pressing the VFO/MR Button
Frequency Mode (VFO) - Used for a temporary frequency assignment, such as a test frequency or
quick field programming if permitted.
Channel Mode (MR) - Used for selecting pre-programmed channels.
Manual programming
Manual programming is somewhat difficult until you get used to it, especially when programming in
duplex channels. Note that the ANI S-CODE IDs can only be set from a computer. When programming
channels it is important to remember that you can only save memory channels when working on the
upper display in VFO mode.

Part Ill. How-to and setup guides.
Part three covers is a collection of how-to documents to help you set up your
radio for specific working environments.
CHAPTER 10 REPEATERS
On manual programming you cannot overwrite an existing channel. You must first delete the
channel before updating or replacing it.
To create a new channel, start by switching your radio to Frequency (VFO) mode using VFO/MR key.
When in Frequency (VFO) mode, select your desired receive frequency using the numerical keypad.
After that, use the menu system to configure the finer details of the channel you're wanting to program
to memory, such as transmit power, bandwidth, CTCSS or DCS and more.
For more information on how to use the menu system see Chapter 4, Working the menu system and
Appendix B, Menu definitions. Information regarding how to set up CTCSS and DCS can be found in
Chapter 8, Selective calling
