ZORRO is powered by 2x 3.7V 18350 Lithium-Ion cells and is charged using the built-in USB-C port. The charging circuitry is designed for charging 2x 3.7V Lithium-Ion batteries only. The nominal voltage is 3.7V and the maximum charging voltage is 4.2V.
Never charge 3.6V LiFe and 3.6V 18350 Lithium-Ion 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.

Model selection and protocol selection

Depending on the package purchased, Zorro has a 4-in-1 quad-chip or a CC2500 single-chip multi-protocol module built-in. To view the latest list of all compatible protocols, please visit https://www.multi-module.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 on 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.
Need to add something here about bind ELRS.

FCC RF Exposure Information and Statement

This radio is designed for and classified as “General population/uncontrolled Use”, the guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. The exposure standard for wireless radio employs a unit of measurement known as the Specific Absorption Rate, or SAR, the SAR limit set at 1.6W/kg.
Body-worn operation; this device was tested for typical body-worn operations with the back of the handset kept at 0mm for body-worn. To maintain compliance with RF exposure requirements, use accessories that maintain a 0mm for body-worn.
