SCP-498 appears to be a Koway Brand RT-800 electronic alarm clock with yellow LED display, set to the U.S. Central Time Zone. When heard by a subject, the alarm has been seen to induce a state of increased alertness until reset. This effect prevents restful sleep in SCP-498's vicinity, although micro-naps are possible. Other than the "snooze" button and the display, none of the other functions on the device appear operational.
