Quick-Start Guide - TBS CROSSFIRE Micro TX Revision 2017-08-23

The CROSSFIRE Micro TX has a standard JR-form factor and works with any radio that supports PPM-

stream and/or TBS CRSF-format output. Transmitter power is selectable between 25mW and 100mW, and

TX status is shown using a RGB LED lite behind the push button. Frequency band 868 MHz and 915 MHz

are supported.

Push button functionality

If there is no link (LED pulsing orange ):

• Long press: Toggle frequency between 868 MHz and 915 MHz. Once changed it will blink white 1x

for 868 MHz and 2x for 915 MHz.

• Short press: Enter bind-mode (LED blinking green ▀ ▀ ▀ ).

If the receivers needs to be updated it will start blinking blue (■ ■ ■ ■ ). Press the button again

to confirm. The update will start and the LED will be solid blue (▀ ▀ ▀ ) until the update is

complete. Once update is complete the LED will turn solid green (▀▀▀) or orange (▀ ▀ ▀ ).

If there is a link (LED solid green ▀▀▀ or orange ▀ ▀ ▀ ):

• Long press: Set failsafe

Configuration of the internal settings (region, output power, dynamic power, and operation mode) and

receiver configuration (output mapping, channel mapping ect. ) is done via any remote supporting CRSF

(TBS TANGO, OpenTX ect.) remote. The TBS CROSSFIRE Micro RX V2 comes with CH1: PPM, CH2-CH4 PWM
