Embarrassed to ask, cannot figure out how to get into recovery on new 5.1 joying HU

Even adb reboot recovery isn't working I've tried holding reset but it just appears to actually reset unlike my 4.4 unit. However this unit has a rotary volume knob and physical buttons. I tried a combination of reset and the buttons as well. This is the unit I have, anyone care to make me feel like an idiot and tell me how easy it is?



Thanks
Dave
