Factory Default Firmware Adjustment:

RT3S walkie talkie supports "Recording function" or "120,000 digital contacts import ing function", but these two function are not available and applicable at the same time due to firmware difference.
Previously the factory default firmware of RT3S is with Recording function.
But now the factory default firmware of RT3S is adjusted to firmware that supports the function of importing 120,000 digital contacts. That means you can directly import 120,000 digital contacts by programming software, instead of flashing into firmware by yourself.

How to check：
Please check whether "ContactsCSV" shows in menu option "Radio Settings".
If yes, then firmware of your RT3S is with 120,000 digital contacts importing function.
If you need recording function,please contact us for a solution.
