WWW.RADIOMASTERRC.COM Quick start guide TX16SMKII Introduction The best just got better Thank you for purchasing the RadioMaster TX16S MKII Multi-protocol radio system. RadioMaster is proud to bring this ground-breaking product to the market and would like to thank customers just like you and the community for making this dream possible. The MKII version has had several improvements thanks to feedback from users like you. Please take a moment to read this quick start reference before using your new TX16S MKII radio. Many radio control models are equipped with powerful motors and sharp spinning propellers. Please exercise caution when working on models. Ensure power is disconnected from your models and remove propellers when performing maintenance. Do not operate the TX16S MKII radio system under the follow conditions. • During bad weather or high wind conditions such as rain, hail, snow, storms or electromagnetic events. • Under limited visibility. • In areas where people, property, powerlines, roads, vehicles or animals may be in present. • If you are feeling tired or unwell or under the influence of drugs or alcohol. • If the radio or model appear to be damaged or not functioning correctly. • In areas of high 2.4GHz interference or in locations where use of 2.4GHz radios is prohibited. • When the battery in the TX16S MKII or the model is too low to function. Safety & Precautions. Manuals and firmware downloads. The TX16S MKII is shipped with EdgeTX software installed as standard. To download the latest software and manual please visit https://www.radiomasterrc.com Further firmware information. EdgeTX: http://edgetx.org OpenTX: www.opentx.org ExpressLRS: https://www.expresslrs.org/2.0/ Multi Protocol Module: https://www.multi-module.org/ CAUTION! The TX16S MKII is shipped with the most stable firmware at the time of manufacture. Please only update firmware if you are experienced and confident in updating system firmware. Incorrect updates may render the radio inoperable. 1 -RadioMaster Team. DO NOT charge 6.6v LiFE battery packs or Li-ion 18650 cells with nominal voltage of 3.6v. Incorrectly charging the wrong battery type may lead to damage of the radio or fire. Regularly check the health and condition of your batteries and never leave your radio charging unattended. Always charge in a safe area away from combustible materials and surfaces. Do not charge if your radio becomes wet or damaged in any way. RadioMaster does not accept any liability for the use or misuses of this product. Antenna Separation Distance When operating your RadioMaster transmitter, please be sure to maintain a separation distance of at least 20 cm between your body (excluding fingers, hands, wrists, ankles and feet) and the antenna to meet RF exposure safety requirements as determined by FCC regulations.

Warranty and Repairs. Please retain your proof of purchase and contact the retailer you purchased your TX16S MKII from, should you experience any problems with your radio hardware. Warranty is valid for one year from the date of purchase. Power Requirements. Model and protocol selection (multi-protocol module) Model and protocol selection (ELRS) The TX16S MKII has built in USB-C charging for 3.7v Lithium cells. The Charging circuit is designed for 2x 3.7v Li-ion 18650 unprotected cells or 2x 3.7v Li-poly cells (2s 7.4v LiPO pack) only with a nominal cell voltage of 3.7v and maximum charge capacity of 4.2v. A wide variety of modules is available for TX16S MkII units with the 4-in-1 module. To find out whether a certain protocol would work with your radio, please visit: https://www.multi-module.org/ Press and hold the MDL button and scroll to the MODEL SETUP page. Under internal RF, set the Mode to MULTI and select the RF Protocol/ sub protocol as desired. Once the protocol is selected, the corresponding RF chip will be activated. Note: -The Bind button starts the bind process, if a compatible receiver is in bind mode within range, it will bind to your receiver. -Range mode cuts the RF output by a factor of 30, allowing for easy range testing. Bind method 1.Turn off the radio. 2.Cycle power to the receiver 3 times, the receiver LED will start blinking, indicating it’s in bind mode. 3.Turn on the radio, enter the ExpressLRS LUA, and select Bind. 4.The receiver LED will now stay illuminated, signaling a successful bind process. Please note that current protocols may be updated, and new protocols added, without prior notice.
