If you have a SportŪ 80C, SportŪ 80M, Multi-SportŪ 2 ^S, Multi-SportŪ 3 ^S, or the G2 version of the models listed you have a T on the transmitter dial that is used to select the tone function.

• For the SportŪ 80 / SportŪ 80 G2 models it works by selecting T on the intensity selection dial and pressing any stimulation button.
• For the Multi-SportŪ / Multi SportŪ G2 models it works by selecting T on the intensity selection dial and pressing the appropriately colored button for the receiver on which you wish to activate the tone.

If you have a multi-dog Classic 70 ^XLS, Trashbreaker Ultra ^XLS, or the G2 version of either model you select the tone feature by selecting T on the intensity selection knob and pressing the appropriately colored button for the receiver on which you wish to activate the tone.  For a 4, 5 or 6-dog system the toggle switch must be in the correct position for the receiver as well.

You cannot select T (tone) and a stimulation level at the same time.  The T also acts as a safety no-stimulation setting.
