(Battery nor AC adapter included with purchase.) Please read and follow the instructions included in the box to ensure optimal performance. If using a battery: A rechargable Ni-MH battery is recommended for best performance and is a more cost-effective alternative to a common Alkaline (single-use) battery. If using an Alkaline battery, it must be NEW. Refer to product information sheet included in box for recommended brands. DO NOT use a Carbon-Zinc battery (often labeled "Heavy-Duty"). This type of battery cannot produce enough power to operate the motor. To get the most life out of the battery, use in intervals no greater than 5 to 10 minutes. Operating in this manner will yield approximately 45 minutes of use. If your tube guy begins to get stuck in a downward position, it is time to replace the battery or recharge if using a rechargeable battery. If using an AC adapter, it must follow the below specifications: Input: AC 100-240V (50-60 Hz) Output: DC 9V (1A or 2A)
