MT12 is powered by 2x 3.7V 18650 Lithium Ion cells or a suitable 2s Lipo battery and is charged using the built-in
USB-C port. The charging circuitry is designed for charging 2x 3.7V Lithium Ion or 2s lipo batteries only. The
nominal voltage per cell is 3.7V and the maximum charging voltage per cell is 4.2V.
Never charge 3.6V LiFe and 3.6V 18650 Lithium Ion cells or packs with the onboard charger. Charging or using the
wrong battery chemistry/polarity may cause permanent damage to the PCB and in certain situations cause fires.
Check the voltage and condition of the battery regularly and never charge the device unattended. Only charge in
safe areas away from combustible materials. Refrain from charging the radio unit if it was exposed to water or was
damaged in any way. RadioMaster does not assume any responsibility for any adverse consequences caused by
the use or misuse of this product.

EdgeTX software is highly versatile, and has a large number of programming and mixing functions. Please
A comprehensive software installation guide is available from the link below for more detailed instructions:
https://www.edgetx.org
Model selection and protocol selection (ExpressLRS version)
MT12 ELRS units equipped with an internal ELRS module are capable of providing 10mW-250mW RF
output (limited to 100mw for EU LBT versions). In non-extreme circumstances, 100mW output at 500Hz
update rate is recommended, as higher RF output and update rates may significantly reduce battery life
and generate excessive heat.
Bind instructions
1：Turn off the transmitter.
2：Cycle power to the receiver 3 times, the receiver LED will flash twice- indicating bind mode.
3：Turn on the transmitter, long press the SYS button and choose the ExpressLRS LUA under the
TOOLS menu. Scroll down to [Bind] and press enter.
4：The LED on the receiver should now be solid, indicating successful bind.
Model selection and protocol selection
Depending on the package purchased, MT12 has a 4-in-1 quad-chip multi-protocol module or
ExpressLRS module built in. To view the latest list of all compatible protocols,
please visit https://www.-multi-module.org/ or https://www.expresslrs.org/ Please note that new protocols
will be constantly updated and added to the latest firmware. Some new protocols may require firmware
upgrades.
Long press the MDL button to enter the model settings, select MULTI in the SETUP page, and select the
desired protocol in the sub-options. The system will automatically turn on the corresponding RF module
according to the RF protocol you selected.
• Bind [BND] is used to start the binding process.
• Range [RNG] button can reduce the power to 1/30 to facilitate testing of remote-control distance.

模型选择及协议选择(内置ELRS高频模块)
MT12 内置ELRS具有10mW-250mW可调范围，最大功率为250mW，在非极限条件使用时，推荐将功率
限制为100mW，并使用500Hz速率，更高的速率会降低控制距离，更高的功率会带来较大的发热和耗电，
请您根据自身需求，合理调整功率及速率，以便达到性能和耗电的平衡。
对频流程：
1：关闭遥控器
2：重复上电接收机3次，接收器LED会进入双闪模式，表示进入对频模式。
3：打开遥控器，长按SYS按钮，在“TOOLS”菜单中选择“ExpressLRS ”LUA。向下滚动至[Bind]并按确定键。
4：接收机上的LED常亮后，表示对频成功
模型选择及协议选择
MT12枪控遥控器提供两种选择：4合1多协议内置模块和Express LRS内置模块，根据您购买的版本，支持不同的
协议。如需了解可兼容协议的最新列表，请访问以下网站：https://www.-multi-module.org
或https://www.expresslrs.org/。
请注意，新的协议将不断更新并添加到最新固件中。有些新的协议可能需要固件升级。
· 请长按MDL按钮进入模型设置，在SETUP页面中选择MULTI，并在子选项中选择需要使用的协议。系统根据
您选择的射频协议，会自动开启对应的射频模块，同时关闭其它三个射频模块。系统在同一时间只会开启一个
射频模块，以确保没有多余的无线电信号相互干扰。
· [Bnd]选项用于启动对频过程。
· [Rng]选项可将功率降低至1/30，以方便测试遥控距离。
