## Questions & Answers

**Q: Can anyone post the instructions on setting/resetting the password?**
A: It is on the instructions in the box. a. Press the "3" button for 3 seconds the alarm will sound a "tick" then input the old password (default setup is 0000)b. After two short sound of "tick" input the new password (note: password is a four-figured number)c. Input the new password again after a long sound "tick"d. After the alarm sounds two long sound of "tick", the password is changed

**Q: Does anyone have experience with both this product and Airzound products? Which is louder / better for alerting vehicles?**
A: The AirZound is both much louder and lower-pitched. And yet, this horn is quite loud (albeit high-pitched) and a bit obnoxious to use on other cyclists or pedestrians in quiet areas. The AirZound isn’t as loud as the pressure in its reservoir drops (rarely a problem, I feel sorry for anyone who has to use it so much that they run out of air pressure during a single ride) while the battery in this combo light/horn will last a long time – months – if the light isn’t used. The electric horn’s trigger can be put in a convenient spot up to about 6 inches from the horn itself but the AirZound’s trigger is a valve built right into the horn body and so can be a challenge to mount in a good spot on some bikes.

**Q: Can somebody give me a picture of english instruction paper or tell me how to set my own password?**
A: If you remove the battery for 10 seconds, the password will reset to default 0000. I never trust stuff - I left the battery out for a minute. Here's a dumb question: did you write this question - drop the instruction paper - and discover the English words on the back?

**Q: It says it has a bell/horn for the bike, is that really the case?**
A: It is a horn. Okay, it is also an alarm ... you go into a store, and if anyone moves the bike the alarm sounds ... Loud enough that people around will look - just to see what's going on, and probably see only a 'stuffed pants' person fleeing the scene. You turn it off using a password ... I also use a cable to attach it to a Something solid and immovable.
