# CC2500 RF Module
## Ares - *108*
Models: ARES Gamma 370, P-51D Mustang 350, RTF models with 6HPA-Tx and AZS12006-Rx (6 channel).
Autobind protocol:
- to bind, power on the TX first
- then power on the receiver - LED slow flash
- press receiver bind button - LED faster flash
- receiver LED will flash quickly (15 seconds) when bound LED turns solid
Receiver numbers (0-63) available for model match, MPM global ID used for unique module identifier. Changing the TX module or RX number will require re-binding the receiver.
Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.
Check the [Frequency Tuning page](/docs/Frequency_Tuning.md) to determine it.
