WWW.RADIOMASTERRC.COM Quick start guide MT12 Introduction Thank you for purchasing the RadioMaster MT12 radio system. Advanced and highly-versatile, the MT12 is adaptable for drivers of any skill level. To ensure safe and reliable operations, please read this manual carefully prior to use. As the software and hardware are constantly improved, the information contained in this manual is subject to change without prior notice. Please visit our website for up-to-date information and radio firmware. MT12 is an open-sourced, ergonomic surface radio with powerful multi-protocol or ExpressLRS capability. Able to bind to most contemporary protocols on the market, this is one radio to rule them all! MT12 runs EdgeTX, an open-sourced operating system; for more information, please visit the EdgeTX link below. -The RadioMaster team Radio-controlled vehicles commonly contain rotating parts such as gears and wheels able to rotate at high RPMs; when operating or maintaining your model, always use common sense and proceed with caution. Always disconnect power to the model during the assembly or maintenance process. Never operate the MT12 radio system in the following conditions: • In severe weather or strong windy conditions, such as rain, hail, snow, storms or electromagnetic environments. • In limited visibility. • In the proximity of other people, property, public roads, vehicles or animals. • When feeling unwell, or under the influence of drugs or alcohol. • If the MT12 radio system/model is damaged or showing signs of interference. • In areas with high 2.4GHz interference or where 2.4GHz radios are prohibited. • When the TX/RX battery is low. • In areas where local regulations prohibit the use of transmitters Safety Information Manual and firmware download MT12 is pre-installed with factory approved EdgeTX firmware. To download the latest manual or stock factory firmware, please visit the RadioMaster website: https://www.radiomasterrc.com To download the latest EdgeTX firmware for your MT12 radio system, please visit the EdgeTX website: https://www.edgetx.org Important MT12 is pre-installed with the most stable firmware at the factory at time of release. please only attempt to update the firmware if you are confident in the process. Incorrect firmware updates may cause the remote control to become inoperable. Damage as a result of improper firmware update may not be covered under warranty. 1 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. Power Requirements.

Please A comprehensive software installation guide is available from the link below for more detailed instructions: https://www.edgetx.org 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 1Turn off the transmitter. 2Cycle power to the receiver 3 times, the receiver LED will flash twice- indicating bind mode. 3Turn on the transmitter, long press the SYS button and choose the ExpressLRS LUA under the TOOLS menu. Scroll down to [Bind] and press enter. 4The 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. 4-IN-1 Version ExpressLRS Version Specifications Physical dimensions177.8*118.4*207.8mm Weight480 grams Operating frequency2.400GHz-2.480GHz Internal RF Options4-in-1 multi-protocol / ELRS 2.4GHz Supported protocols Module dependent Operational current: 160mA for 4 in 1. 400mA for ELRS 250mW .
