Try
1. Turn the mode dial to SETUP.
2. While pressing both the down arrow button and the telephoto button, turn the power on.
3. A table will be displayed on the monitor. If "V 1.00" (or a lower number) is displayed in the CPU2 field, you will need to update your camera's firmware to the most recent version. SH is the shot counter.

I have a GX8 which is almost the same. I found the buttons a little hard to use.
See if you can find a HA-1 & DW-4 to go wide angle. The ring around the lens should screw off. Also your lens has a small nick at its bass like the GX8.
