Maico MA 53 Audiometer Device Analysis Report

Overview and Device Description

The product shown in the images is a clinical audiometer device designed in a portable case form, used for conducting hearing tests (audiometry). The device has an integrated carrying and storage case. The analyzed images show 1 unit of the Maico MA 53 main unit, along with various accessories inside. The general condition of the product, based on signs such as yellowing and wear on the label, indicates that it is used.

Brand and Model Information

A detailed examination of the device’s front panel clearly shows that its brand is Maico and its model is MA 53. This information is indelibly printed on the device.

Physical Condition and Deformation Analysis

While the physical condition of the device is generally good, some cosmetic defects due to use have been observed.

• Casing: The grey plastic casing of the device has no significant breaks, cracks, or dents. However, there is slight yellowing and discoloration, particularly on the lid and edge areas, which appears to have occurred over time.
• Labels: The label explaining the functions, located on the inside of the device lid and titled “Second – Level – Functions MA53”, is quite worn. There is peeling at the edges of the label, and wrinkles and dirt accumulation on its surface.
• Buttons and Knobs: All buttons on the front panel and rotary adjustment knobs on the sides are physically in place, and no cracks or breaks have been detected on them.

Mechanical and Electronic Components Examination

Based on visual inspections, no significant malfunction is observed in the mechanical and electronic components.

• Mechanical Components: The lid hinges and locking mechanisms of the device appear sturdy. The inner foam compartment where accessories are placed is in a condition to perform its function.
• Electronic Components: The device’s digital screen has no cracks or physical damage, but since the device is not operational, no comment can be made about the screen’s functionality. There are various socket inputs on the sides of the device, and these inputs physically appear flawless.
• Battery: A statement regarding battery testing is present on the label inside the lid, which suggests that the device might have an internal battery. However, no observation can be made about the battery itself or its physical condition (swelling, leakage, etc.).

Accessories and Equipment

Various test accessories are found in the device’s storage compartment. The available accessories include:

• One headset with headphones, one red and one blue.
• Various connection and power cables.
• Other unidentified test apparatuses and cables.

It cannot be determined solely by looking at the images whether the full list of accessories matches the original set or if any parts are missing.

Label and Code Information

Detailed technical labels on the device, apart from brand and model information, have been examined. However, the following information was not found in the images:

• Serial Number
• Lot Number
• REF Code
• Year of Manufacture

A label containing this information could not be detected in the available images.

Potential Risk Assessment

The fact that the device is used and the yellowing of the plastic components indicates that the product has a certain age. The highly worn function label inside the lid may indicate heavy usage. Nevertheless, no critical risk factors, such as serious physical damage, crushing in cables, rust, or broken parts, that would directly impede the device’s operation or lead to a malfunction in the near future, were observed in the images. Despite its cosmetic defects, the device physically maintains its integrity.
