Unfortunately, lurkers can't reply. There are 22 lurkers logged onto the forum right now for every member, so odds are only 4 of the people who viewed your thread could reply.

The P5100 has no LED notifications. You can set notification to alert you by a tone and notifications will always appear in the Notification bar. You will have to check the specific manual as the notification setup differs from model to model
