You can also change this setting using <TX> <RPT mode>.
• Set up repeater offsets using <TX> <RPT OFS>.
• Set up VFO coarse-tuning step size using the VFO Coarse
Tuning menu entry.
• Set up PL tone encode pitch and on/off using <TX> <PL TONE>.

• DTMF tones (dual-tone, multi-frequency) can be transmitted in FM
mode. Use <TX> <DTMF> to bring up the DTMF window. Hold PTT, tap
digits or symbols on the provided keypad, then release PTT. You can
also create stored DTMF commands. Hold <CMD1> - <CMD6> to enter
a sequence. Tap the return arrow to complete entry. The CMD button
can then be tapped to play the sequence back (while PTT is asserted).
