Clicking this menu brings up a second menu with four entries, each of which bring up a menu like the one below on the right:  
  
As you can see from the menu on the left, we allow you to create a different chime for every quarter-hour. On the right menu:   

• Clicking "None" means you want no chime to sound.
• Clicking "Talking" causes the chime to be announced by a human voice.
• Clicking "Ship's Bells" invokes the Navy's traditional method of marking the passage of time. 12:00 is eight bells, 12:30 is one bell, 1:00 is two, 1:30 is three, and so on, adding a bell every half-hour until eight bells at 4:00. Then 4:30 is one bell, and so on. Since most people don't need this feature, the bell sounds are not included with the clock install program (to keep the download as small as possible). If you want to use this feature, download our bells from our site. This feature is only available on the hour and half-hour, not at :15 or :45 minutes.
• Clicking the entry just above the horizontal line allows you to select a WAV file for the chime. You can select any WAV file from any directory. 
• The clock also offers PC-speaker sounds, which can be selected below the horizontal line. Note: the PC-speaker sounds do not work correctly on some PCs. If you have multimedia options installed, we recommend you use a WAV file for your clock sounds.
