Please follow the steps below at first to self-check - Use Support 5V -1A Charging with USB-C Port to charge MEAZOR (takes 2 hours to fully charge). Please note that MEAZOR doesn't support adapters with fast charging protocol. - Unplug and wait 4 seconds then restart the device. If you still have still cannot to charge, please contact support@hozodesign.com for further assistance.

Please send the following information to our support team to help a quicker investigation: - Has the blue indicator light always on and the screen does not light up of the MEAZOR? - Which specific function/condition leads to crashes? - What is the frequency of product crashes? - MEAZOR firmware version number - MEAZOR serial number Please send us pictures or videos about the MEAZOR crash if you could, so that we could forward to our engineer to solve your problem faster, and please contact us at customersupport@hozodesign.com at your convenience.

The serial number of MEAZOR could be found beside the box, and all the products with the serial number on the box is eligible to the 1-year limited warranty, it’s not a test device or demonstration. We've updated the position of the serial number and didn't update it in the user instruction for devices produced before Mar, 2022.

The measurable distance of laser measurers ranges from from 0.1m-25m (0.3feet-82feets), the measurement accuracy stands ±2mm (±0.08 inch)

Rolling Ruler is recommended to measure the length that less than 5m. The measurement accuracy is ±0.2% on rough surfaces, and the accuracy will be impacted due to human error when measuring long distance.

There are three blue indication lights at the bottom of the product for aligning the measurement start/end points.

4 built-in scale modes with 57 scales in total - Metric Architecture - Metric Engineering - US Architecture - US Engineering

There are 2 modes of 2D floorplan scanning function: 1. Point Scanner: Point Scanner is a manual positioning mode that allows you choose key points around the room for precise floorplan captures. It fit measuring demands of floorplan and room plan. 2. Curve Scanner: curve scanner is an automatic mode that can perform scanning by simply turning the machine 360 degrees. It suits measuring demand of odd-shape/curve-shape objects, structures and architectures.

Curve scan is designed mainly for the measurement of irregular curves. Place the product horizontally on the edge of the curved surface and turning the body 360 degrees. The measurement could be sent to the APP for editing via Bluetooth.

Point scanner and curve scanner can measure the maximum area of 1200m² (12900feet²). The measurement error is proportional to the area of the scanned floor: ±0.5cm-±10cm (0.2inch-4inch). The source of the measured area and accuracy data is from laboratory test results.

MEAZOR does not support internal data storage, but if you use MEAZOR App, there is no limit on data storage.

The theoretical standby time for a fully charged MEAZOR is around 30 days, and the continuous working time last around 16 hours. Battery capacity is 650mah.
