## Questions & Answers

**Q: No real instructions included in the box. Any link? I most likely missed an email thinking it was spam**
A: The link is listed on the webpage describing the product, under product information subheading technical specifications.  For your convenience, I have included it here:  https://m.media-amazon.com/images/I/A1lnIHkuKNL.pdf

**Q: After soldering the components do I need to program this with software on my pc or is this a simple learning to solder kit?**
A: No software needed this is a soldering kit.

**Q: is there any way to make it a 12 hour clock instead of a 24 hour military clock?**
A: Thanks for your question. I am sorry for that the item just has 24 hour military clock, can't be made it into 12 hour. If you have any other questions, feel free to contact us. Thanks for you kindly understanding and have a nice day.

**Q: After assembly, the buzzer continues to buzz as soon as power is supplied to the unit. I am able to navigate through the menus fine. any solutions?**
A: When I plug in my clock, it shows 12:59 and one minute later the alarm will ring as the default alarm is set for 1:00.  After going through the menu and setting the correct time and turning off alarms it works fine.

If your clock buzzes all the time, you probably have a short when you soldered the buzzer causing power to be supplied to the buzzer continously.  Recheck the soldered connections at the buzzer.
