4.1 Battery Installation and Charging

The TX16S Mark II MAX Edition operates on a DC voltage range of 6.6-8.4V. It features new charge circuitry with integrated reverse-polarity protection and optimized charge IC for better balancing and USB-C charge current management.

1. Open the redesigned battery cover located on the rear of the transmitter.
2. Insert the compatible battery pack, ensuring correct polarity.
3. Close the battery cover securely.
4. To charge, connect a USB-C cable to the transmitter's USB-C port. The charging status will be indicated on the display.

4.2 Firmware (EdgeTX / OpenTX)

The transmitter comes with EdgeTX installed by default (touch screen enabled). Firmware updates can be performed via USB-C online or SD card offline upgrade methods.

• USB-C Online Upgrade: Connect the transmitter to a computer using a USB-C cable and follow the instructions provided by the EdgeTX or OpenTX community for online updates.
• SD Card Offline Upgrade: Download the desired firmware to an SD card, insert it into the transmitter's SD card slot, and follow the on-screen prompts for offline updates.

4.3 Module Installation

The TX16S features a JR compatible module bay, allowing for the use of external RF modules in addition to the internal multi-protocol module.

• Internal Module: The transmitter includes an internal 4-in-1 multi-protocol module (CC2500 CYRF6936 A7105 NRF2401) or an internal ELRS (Sx1280) module, depending on the option purchased.
• External Module: To install an external module (e.g., Team Black Sheep MicroTX), slide it into the JR compatible module bay on the rear of the transmitter until it clicks into place.
• Module Selection: The TX16S allows switching between internal RF and external modules (like Crossfire) via software settings, eliminating the need for physical module swapping.

5. Operating Instructions
