• Can I charge LiFE or Li-ion 3.6V batteries with the HelloRadio built-in charger?

  No. The built-in charging circuit is designed strictly for 2x 3.7V Li-ion 18650 unprotected cells or 2x 3.7V Li-poly cells (2S 7.4V pack). Charging incorrect battery types like 6.6V LiFE or 3.6V nominal Li-ion cells may cause fire or damage to the radio.

• What separation distance is required for the antenna?

  When operating the transmitter, maintain a separation distance of at least 20 cm between your body (excluding hands and feet) and the antenna to meet RF exposure safety requirements.

• How do I update the firmware on my HelloRadio V14 or V16?

  The units ship with stable EdgeTX software. Firmware updates should only be performed by experienced users via the USB-C connection or SD card. Incorrect updates can render the radio inoperable. Official firmware can be found on the HelloRadio webindawo.

• What should I do if my HelloRadio transmitter gets wet?

  Do not attempt to charge or power on the radio if it has become wet or damaged. Disconnect the battery immediately and contact the retailer or support for guidance.
