Precaution
Sassy is designed with highest quality components and handcrafted to extreme precision for
extended service lifespan. Still, users are advised to be cautious on usage to avoid damage due to
carelessness.
1. Avoid high-G force shock on Sassy. Due to nature of vacuum tubes, extreme shock may lead to
microphonics noise at output
2. Microphonics is the ringing noise induced by vibrations of vacuum tubes. Though
countermeasure has been taken to minimize it. When happens, keep device steady for few
seconds and the noise shall fade away soon. If noise extended, keep device steady and turn
Sassy off then back on.
3. Please recharge battery before use. It takes 3-hour to fully charge when battery is empty
4. Sassy, same as all electronic devices, shall avoid high humidity or water-spill
5. Only use certified 5V USB charger and cable for battery recharge
