631 display getting dim


New member
I have had this unit for about 1 1/2 years and the display is so dim I can hardly see it. Going back and adjusting levels in the control panel doesn't help.
Is this the life expectancy of this device?

The white LED backlights are rated at 10K hours--which is a little over a year.
Thanks for the reply, I wish I would have known that I had to replace this thing every year, I guarantee I would have gone a different direction.
You should at least give repeat buyers a discount.

CC2 has a timeout function that can reduce the backlight in times of inactivity.
