Questions & Answers

Why tha devices make a little noise or buzzing sound

Asked by: Oscar
In some cases, users, particularly younger individuals, may notice a faint buzzing or high-pitched noise coming from the device. This sound is typically associated with the ultrasonic sensor component, which can emit a subtle noise as it begins to fail. If this is the case, we recommend replacing the unit. The UT-305-2 is a suitable and compatible replacement for the W-1000A.
