The last time I used my little VX-2 Yaesu handheld was probably 8 years ago.The battery was flat and I had forgotten how to operate it! Charging the battery was no problem, but how did you set the CTCSS tone?
I Googled "VX-2 Yaesu operating manual" and this link appeared:
https://www.manualslib.com/manual/969822/Yaesu-Vx-2r.html#manual
Problem solved. I expect there are all sorts of manuals somewhere on the internet.
The Yaesu VX-2 can be obtained from Radioworld at just over £117.
