• Under limited visibility.
• In areas where people, property, powerlines, roads, vehicles, or animals may be present.
• If you are feeling tired or unwell, or under the influence of drugs or alcohol.
• If the radio or model appears to be damaged or not functioning correctly.
• In areas of high 2.4GHz interference or in locations where the use of 2.4GHz radios is prohibited.
• When the battery in the TX16S MKII or the model is too low to function.
• In areas where local regulations prohibit the use of model aircraft.

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.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

This product contains a radio transmitter with wireless technology which has been tested and found to be compliant with the applicable regulations governing a radio transmitter in the 2.400GHz to 2.4835GHz frequency range.

Antenna Separation Distance

When operating your RadioMaster transmitter, please be sure to maintain a separation distance of at least 20 cm (approximately 8 inches) between your body (excluding fingers, hands, wrists, ankles, and feet) and the antenna to meet RF exposure safety requirements as determined by FCC regulations.

Power Requirements

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 a maximum charge capacity of 4.2v.

Model and Protocol Selection (Multi-protocol module)

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/

Please note that current protocols may be updated, and new protocols added, without prior notice.

MODEL SETUP

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.

• 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.

Model and Protocol Selection (ExpressLRS)

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.

Support, 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.
