8)Operator Selectable Tone (TK-270G K types only)

This key switches the pre-set decode QT/DQT and encode QT/DQT to OST (Operator Selectable Tone) tone pair. Press this key, the transceiver enters OST mode. In this mode, the display shows "OFF" and the operator can select

one of the OST tone pair using the tuning control. The display shows "TONE ∗∗" and tone pair No. ∗∗ is selected.

Press OST key again, the transceiver exits from OST mode, and returns to the group/channel mode.

16 tone pairs for OST can be programmed by KPG-56D. OST is useful to access the repeater with same radio frequency and different tone (QT/DQT).
