king surelock antenna signal meter SL1000

[Green army]

Hi all

Help, I’ve inherited the above piece of kit but other than the power light the remaining lights don’t light!

The meter has been stuck onto the bulkhead so cannot access the back very easily, am I right in assuming this is where the pp3 9volt battery goes.
Any assistance/advice greatly received

Thanks

Martin
