I walk on a treatmill every night after work. To ease the boredom of looking at my garage's bare walls, I listen to music thru a 3 year old Panasonic portable CD player with its 10 second anti-shock on. The player is placed on the display panel of the treatmill. Anyway, while I was grooving to the CD of Elvis' recent "Elv1s" compilation, the player skipped. It skipped another 2 times over the course of my 45 minute walk. It's not like I'm running, causing the skipping. The player has skipped before, but I attributed it to the vibrations caused by my walking. But it has skipped more in recent days. Is this an indication that the player is about to bite the dust? Am I looking for an excuse to buy another portable CD player. Does battery life affect the effectiveness of the anti skip feature?? Any advice will be helpful. (In Elvis' voice") Thank you very much.
