Using the Prisma HD
Reading with the Prisma HD
Place the Prisma HD on a suitable table near the television
and sit in front of it. Ideally the television should be at eye
level or slightly below, and the Prisma HD reading table
should be level with your elbows when seated. A good
reading position prevents problems with your back, neck
and arms.
