The RS800CX watch is shipped with the H3 Transmitter, which is 2.4GHz-only. The RS800CX watch can receive both the 5KHz and the 2.4GHz, but the standard transmitter is 2.4GHz only. This will not work with the 750T, 751T or any other Cybex equipment.
More information: All Cybex equipment has the same wireless receiver technology in them. We use the 5kHz analog signal that Polar pioneered and still uses today. We can receive coded or non-coded 5kHz transmitters. Sample Polar belts are the T31 (5kHz), T31 Coded (coded 5kHz), Wearlink (coded 5kHz), Wearlink Hybrid (coded 5kHz and 2.4GHz WIND), H1 (coded 5kHz), H2 (5kHz and 2.4GHz) and H7 (5kHz and Bluetooth).
We do not support (so far) the new Bluetooth, 900MHz, 2.4GHz, or ANT+ transmitters unless they are ‘combo’ types which also use 5kHz.
