Ailunce HD1 Dual-Tone Multi-Frequency Signaling (DTMF)

Does the HD1 supports DTMF?

Absolutely Yes. Ailunce HD1 is a dual-band DMR radio. The original firmware doesn't support DTMF. But we have added it via upgrading the firmware.

If your radio firmware is before V1.54, you need to upgrade the Newest firmware to achieve the DTMF. Only the V1.54 and the above V1.54 support DTMF function.
