SammichFM Kit LCD Backlight

Apologies if this has been covered before, but I recently bought a SammichFM kit from Wilba, with the (really nice) neg. green LCD display. I decided to try to put together the base PCB without the jumper to supply a larger voltage to the LCD backlight. The display looks OK, but is quite dim. Should I add this jumper at JR4A? I'm reluctant to try it without confirmation that it won't fry the display.

Cheers,

All the LCDs I sell now are high-power LCDs and require a shunt in JR4... otherwise the LCD only gets low current (max. 25mA) which is only good for edge-lit LCDs like some white-on-blue LCDs or the amber/true green ones I was selling in the first few batches (before I switched to standard yellow-green LCDs).
