New Zoom Multistomp MS70 not working?

Hi guys.
Ive just bought this pedal but its not working. I’m running it off batteries into an amp. The amp is tested and working fine. I have to connect a jack into the right input for it to start up. And then connect my guitar into the left jack (mono). Which is the opposite of what it should be. However in the troubleshooting section it says you have to connect the input jack to the amp if running off batteries. Which is what im doing. But i’m getting no sound at all through the amp. It was however working yesterday. All i did was add a few patches to the memory. The batteries are fully charged and brand new? I’m perplexed as i’ve run out of ideas?

Many thanks for any help.
