Getting Familiar

Battery Maintenance

Please use BAOFENG designated battery; other batteries can cause explosions,

Note

1. Do not short-circuit the battery terminals or dispose of in fire. Do not disassemble the battery by yourself.
2. Charge the battery between temperature 0º C and 45º C. The battery cannot be fully charged beyond this temperature range,
3. Turn off the power when you charge the radio.
4. Remove the radio from charger when charging has completed.
5. Replace the battery when operating time becomes insufficiently low.
6. Do not charge when the battery or the radio is wet. Please dry it with a cloth before charging to avoid any danger.

If conductive metals, such as jewelry, keys or chains, contact the external charging contacts, damage or personal injury may occur,

Be sure the output DC is 5V/1A, when you choose micro USB for charging. Never exceed 1.5Ai It is also suggested to use the desktop charger while possible.

Installing External Headset
Gently displace (do not remove) the micro/speaker jack cover, insert the headset into the micro/speaker jack.

Basic Operation

Quick Start Guide

1. Carefully open the box and remove the radio body, battery.
2. Install battery in the radio body.
3. Turn on power knob by twisting gently counterclockwise, The radio will respond with "Open the radio, I" or whatever channel is selected by the taller selector.
4. Select your desired channel, the radio will respond with "One, Two, etc." 5, Press the PTT and talk!

Note
The battery included with the radio generally has enough power in it to test your radio- You should fully charge the battery for optimal performance.
The GT-22 is a cost-effective FRS analog radio. It can communicate with any other brand of radio that is FRS analog, but without spending an exorbitant amount of cash! You just need to make sure they are in the same channels and frequencies, and this can be simply checked by using the software.

Squelch
The squelch level will determine the signal strength at which the radio speaker is turned on. If the squelch level is low, the background noise of the radio speakers will be higher, the corresponding communication range will be further, but the anti-interference ability will be weaker.
The default setting of the squelch level is 3, You can adjust it through the menu "Squelch Level" in the software from level O to 9, and 0 is the lowest level.

Battery Save Function
This function can be set by the software.
By turning on this function the standby time can be much longer.

1. ON: Entering into the battery saving state automatically without any operation for I O seconds.
2. OFF: Battery saving is off.

Busy Channel Lockout
You can turn on/off this function via software.

1. If the current channel does not have CTCSS/DCS, when there is a signal, TX prohibited when you press PTT.
2. If the current channel does not have CTCSS/DCS, when there is a signal which does not have CTCSS/DCS, TX prohibited when you press PTT.
3. If the current channel does not have CTCSS/DCS, when there is a signal which has CTCSS/DCS, the radio will transmit when you press PTT,

Voice Broadcast
You can turn on/off this function via software.

1. ON: When the voice switch is on, the function and channel number are voice broadcast for each channel.
2. OFF: When the voice switch is off, there will be no voice broadcast on each channel.

Low Battery Indication
When the radio is in transmitting or standby and the battery capacity reaches the pre-determined low level, a low battery alert tone will be heard. The indicating tone will be "Please charge the battery". When the low battery alert occurs it cannot transmit, please change or charge the battery.

TOT
This function can be set by the software.
This feature provides a safety switch, which limits transmission time to the programmed value. This will promote battery conservation by not allowing you to make excessively long transmissions, and in the event of a stuck PTT switch, it can prevent interference to other users as well as battery depletion,

VOX
Speak to the microphone in a normal voice to transmit, no need to press PTT switch, turn VOX on/off through the software.

1. When VOX is on in your working channel:
   Speak to the microphone directly, it will transmit automatically.
   The radio stops transmitting when there is no voice, and waits for receiving,
2. When a headset with a microphone is used:
   When VOX is on, you should VOX again for the radio to identify voice volume.
   If the microphone is sensitive enough, the radio will start transmitting.
   If the microphone is not sensitive enough, the radio cannot collect your voice. Please adjust your voice volume to guarantee smooth communications.
3. VOX gain level: When the sound level is higher than the level of VOX, VOX automatically transmits. The VOX gain level can adjust from 1 to 5 levels.
4. When a signal is received, VOX will not transmit even if the sound level is higher than the set VOX gain level,

QT/DQT (CTCSS/DCS)
QT/DQT (CTCSS/ DCS) is the sub-audible signaling, to prevent the radio from receiving unwanted signals on the same frequency. When CTCSS/DCS is set, then within the communication range, you can only receive signals from the same frequency with the same QT/DQT setting. When the QT/DQT is off, you will get all the signals from the same frequency within the communication range.

CTCSS

DCS

   6. If you have to program multiple walkie talkies, you can repeat the above steps.

Trouble Shooting Guide

When reading or writing frequency, I do not get a response or it reports a communication error?

1. Check your programming cable to see if it is damaged.
2. Check the connection of the programming cable and computer serial port.
3. Check to find if the GT-22 battery level is low or depleted. If it is please replace or charge the battery.
4. Check the programming software is matched with the current model.
5. Check if you turn ON your radio.
6. Check that the proper software drivers are properly installed.

When programming is done, why can't my two radios talk to each other?

1. Make sure the two radios are on the same channel.
2. Check the same channel is set to receive the same QT/DQT (CTCS / DCS).
3. Check the range of the radios (Line of Sight).
