ACME Silent Dog Whistle AC535GP []

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. This training dog whistle can produce sounds ranging from those audible to humans to those only dogs can hear. By rotating the lower part of the flute, you can change its length and adjust the pitch. First, start by finding sounds that your dog reacts to. You can teach your dog commands by blowing into the device, and use it as a signal for training and discipline. You can check the sound quality in the video.
