CAN YOU HEAR ME NOW?

Stayed at the Sheraton Grand in Sacramento last week. I haven't followed the Americans for Disabilities Act too closely, but I have noticed that hotel rooms have continued to add more and more signage for the hearing impaired. One sign for the fire alarms that always catches my eye says "alarm sounds like whoop". I can't figure that one out because if you have never heard a whoop how would you understand that? and if you have, but cannot hear now (thus needing to read the sign) how would you know there is a sound?

In any case, this time at the Sheraton I noticed that the TV remote control bore a sign which read:

"CLOSED CAPTIONS PRESS MUTE"

Whoever came up with that one ought to go back to the drawing board!
