It features a programmable sleep mode with independent sleep volume, too (select 15, 30, 60, or 90 minutes), so you can drift to sleep or wake to your choice of a favorite radio station, a favorite CD track, or any of the unit's 4 nature sounds: ocean surf, rushing brook, forest spring, and wind chimes. The T617S's 2 alarms each function independently, so both can be set for either the same or different wake signals.

For radio listening, you'll enjoy drift-free digital PLL (phase-locked-loop) tuning with 12 preset stations for 1-touch tuning convenience for your favorites (6 FM, 6 AM). Use the clock's handy Smart Knob to quickly and easily adjust all settings and major functions.

Ideal for a portable MP3 player or cassette player, the T617S's auxiliary audio input broadens your listening options to include any source you deem appropriate. Hookup with portable audio devices is a snap using the supplied stereo minijack-to-minijack audio cable.

And, just to make sure you never miss an important appointment (if only some quality time with your shower or morning coffee), the clock also comes with Timex's Sure Alarm battery backup. Just install 3 AAA batteries (not included) to activate this feature. In the event of a power failure--or if you disconnect the AC power cord to move the clock--Sure Alarm will maintain your clock and alarm settings for the life of the batteries, ensuring that the alarms will sound at the appointed time (while operating on battery power, the alarms will sound only as buzzer).
