・This device is used for collecting records, and necessary recording data should be promptly transferred to another recording medium.
・Due to repeated overwriting, the microSD card needs regular formatting or replacement with a new one.
・Fix the tire pressure sensor with double nuts. Check for air leaks with a spray bottle containing one drop of detergent.

【About Dark Current】
・If you use the parking monitoring function of this product, a current of about 17mA (dark current) is constantly generated even when the key is off. Therefore, if you do not ride your motorcycle for 1 week to 10 days or more, battery drain may occur. The factors that cause battery drain vary depending on battery capacity, deterioration status, mileage, and vehicle usage environment.
・If you do not use it for a long period, please check the battery voltage frequently or perform supplementary charging using a smart battery charger (such as KDR-B12). If you want to avoid dark current, please connect the positive and ACC wires to the accessory power supply. (The parking monitoring function cannot be used.)

The vehicle is being used in a manner prescribed by the Road Traffic Act.

What is a product defect?
A product defect is a malfunction which can be restored to the original specifications of the product by repair or replacement. However, cases where the product specifications (specs, functions) do not meet the user's requirements are not considered product defects.
What is an initial defect?
If a malfunction occurs due to defects caused by individual differences in materials or manufacturing during normal use within 6 months of purchase, and the symptoms can be clearly confirmed in advance with images or videos, it may be considered a manufacturing defect, and we will first mail a replacement product free of charge. After receiving the product, you will use the return envelope enclosed and return it to us for inspection. If the product is not found to be defective upon inspection, we will replace it for a fee. Even if it is within 6 months, depending on the product and the state of damage, it may not be considered a manufacturing defect. We will handle it as a manufacturer's warranty, not as a manufacturing defect.
What is a manufacturer's warranty?
If a breakdown or other problem occurs during normal use due to defects caused by individual differences in materials or manufacturing, etc., we will repair or replace the product free of charge within the warranty period set for each product (including shipping costs for repair or replacement). The purpose is to protect customers from damage caused by damage to products that would not normally be damaged due to individual differences in the product. In addition, the purpose is to understand the product-specific defects and characteristics that are discovered through actual use, and use this information to improve the quality of products that we plan in the future.
Warranty period
The warranty period is from the date of purchase to the date stated in the product information. If the warranty period has expired, repairs or replacements will be available for a fee. For products that cannot be repaired or replaced, please purchase a new product.

If there is no problem with the product, you will be charged for the round-trip shipping fee. Please be aware of this in advance. We strive to narrow down the cause of the defect as much as possible before returning the product so that the shipping fee is not borne by the customer. After-sales service staff cannot visually grasp the actual situation, and the problem assumed by the after-sales service staff may differ from the actual problem based on verbal or written explanations alone. Please be sure to attach photos and videos, and perform troubleshooting as much as possible before the after-sales service staff provides guidance.
