Press the MENU button, rotate the SUB-TUNE knob to select Menu #12,
That is "TONE-FRQ".
Then rotate the MEM/VFO CH knob to set the right PL.
Then press the MENU again to exit.

To activate PL just select FM-mode and press the grey TONE knob (3).
There is a sign ENC visible. You can check that the PL is correct
by pressing the MENU again. IF not, just rotate the MEM/VFO CH knob.

If that doesn't work out, maybe the memory backup battery has run out
of juice. Check also the position of the battery backup switch.
