0 . [ Description of Key Features of Technician's Note ]

This diary is not just a simple work log.

It was designed as a diary for professional technicians,

and was personally designed and produced by a technician who has worked in this field for a long time.

All content includes explanations;

you can import image files from your smartphone,

take photos of only the necessary parts with your smartphone,

save them,

and import PDF files to save

so you can refer to them immediately when needed.

For example,

you can take photos of only the key parts of drawings or part lists,

and save them,

and use the zoom in/out function for reference.

There is no need to spend time creating and saving images.

Just take photos with your smartphone camera and save them.

Photos have built-in graphics (circle, square, straight, pencil, crop, etc.) and cropping functions, so a separate image editing app is not required.

All data can be backed up and restored.

Backed-up data can be passed down to a successor or sold to others.

1. [Know-how Diary]

The diary is a core feature that allows you to take photos of problems and your experience handling them, along with explanations, to save them.

Save your own field experience or the experiences of others, and do not waste time relying on old memories for the same content.

Search by keyword for data categorized by manufacturer and equipment, and utilize it immediately.

1. [My Own Error Codes]

Error codes provided by manufacturers do not support solutions for all causes.

They can only provide the scope of the malfunction or hints.

By analyzing and saving your experiences in resolving specific codes,

you can create a practical error code book.
**Save the code where the problem occurred and the experience of handling it by taking photos along with explanations.**

You can refer to them if the same problem arises again.

Save your own field experience or the experiences of others, and do not waste time relying on old memories for the same content.

Search by keyword for data stored categorized by manufacturer/equipment and utilize it immediately.

2. [Managing Electrical Wiring Diagrams/Electronic Diagrams]

Many booklets are required to refer to the vast number of drawings categorized by manufacturer/model.

The actual drawings are small and difficult to read.

Now, import the drawings as image files or use your smartphone camera to photograph and save the necessary parts.

Then, you no longer need heavy booklets, and easily find what you are looking for using the zoom in/out functions.

You can refer to photos along with explanations.

Search by keyword for data stored categorized by manufacturer/equipment and utilize it immediately.

3. [Managing Machine Drawings/Part Lists]

You can refer to photos along with the descriptions.

Search by keyword for materials saved by manufacturer and equipment, and use them immediately.

4. [Assembly Sequence / Equipment Setup Management]

Disassembly and assembly relying on memory lead to mistakes.

Even after assembly is complete, you often feel anxious wondering if anything is missing or if it was assembled incorrectly.

In fact, there are many cases where you have to redo the work.

Record the key points related to the disassembly or work process.

Checking periodically while working will reduce your worries.

Also, setting up equipment is complex and difficult to remember.

If you attach photos along with explanations of the setup sequence or details, you will no longer have to waste time.

5. [Parts Management]

There are many types of parts, and many are similar, making them difficult to remember.

If you record part numbers, names, and specifications, along with descriptions and photos, you can look up everything related to the parts.

Additionally, if you document how to modify discontinued parts, you can perform consistent work quickly.

6. [Managing Parts Requiring Dimensions]

Some parts, such as tires, wheels, and hoses, require dimensions.

If you record detailed characteristics along with descriptions and save photos, you can easily find and utilize data managed by manufacturer/equipment.

7. [Catalog Management]

Catalogs record specifications, performance, and other details regarding equipment.

By importing images, PDF files, or directly photographing and saving key sections of the catalog, you can easily find and utilize data managed by manufacturer/equipment.
