Mini1300 v1.01 VSWR Freq Markers and snapsot issue

[SolarPoweredWok]

I have been unable to find detailed documentation of this Mini1300 analyzer, so I am not sure if this is a firmware limitation or I need instructions on "how to". Mine has v1.01 firmware.

Issue 1. Using the Frequency Sweep Mode on the VSWR screen there is M1 M2 and M3 to the right. I assume markers which I wanted to set up on the display but unable to get them to function. I tried moving the vert dotted line located at the min VSWR to 2:1 and clicked M1 but nothing displayed or stored.

Issue 2. Screen Snap Shots were saved and I can view OK in Manage Snap Shot menu, however how can I transfer out of the mini1300 to my Windows PC. The PC cannot see the Mini1300 as a drive when connected. Do i need a specific driver?
I am using the USB port used to charge the analyzer. I think the other port is for firmware upgrades (assume), however it is not seen by the PC either.

Many thanks in advance.
