About M12S Super Response Modes:
If you're using Analog servos in your model, DO NOT use the SHR or SSR Channel Response Mode for those channels. Use the NOR Channel Response Mode with Analog servos. Using SHR or SSR Channel Response Modes with Analog servos can result in poor performance or even damage to the servos and/or the receiver. SHR and SSR Channel Response Modes should only be used with Digital servos. While the SHR Channel Response Mode can be used with any brand of Digital servo, the SSR Channel Response Mode should only be used with Airtronics or Sanwa Super Response SRG Digital servos. Not all ESCs are compatible with SHR or SSR Channel Response Modes. If your ESC does not operate correctly, change the Throttle Channel Response Mode to NOR. SSR Channel Response Mode is only available when used with compatible FH4 or FH4T Super Response receiver.

About Telemetry Support: The included RX-472 2.4GHz FH4T Super Response SSL receiver does not feature full Telemetry support (e.g., Temperature data and RPM/Speed data). Full Telemetry capability is supported only when used with a Sanwa Super Vortex series ESC plugged into the SSL slot. This is due to the fact that full internal Telemetry support slows the Response Time of the receiver and Sanwa chose to include a receiver that will allow you fastest Response Time possible for competition racing. Full Telemetry support requires the use of an Airtronics or Sanwa 2.4GHz FH4T Telemetry-capable surface receiver (RX-461, RX-462) or SSL-compatible ESC (e.g. Super Vortex series ESC). Steering and Throttle Output and Lap Times can still be viewed when used with non-Telemetry capable receivers.
