## What is ペンライト de YEAAH?

This application allows you to create penlight-like effects with your smartphone even if you do not have a penlight.
It can be used at various entertainment venues such as live concerts, theme parks, etc., where users can participate in the excitement of the event.
The app not only glows in multiple colors, but also displays an animated logo when shaken, making it possible to enjoy it more actively and positively than penlight apps that simply glow.

■ How to use

Press the menu button at the top right of the main screen to display the settings screen. (If it is not displayed, tap the screen to display it.)
There are two setting modes.

-"Settings In Bulk" mode
You can set screen colors, logos, decorations, etc. all at once.
You can choose from a variety of patterns, including a mode that changes when you shake the screen, a mode that changes automatically without shaking the screen, and a country support mode.
All you have to do is select the item you want to set and you're done! Once you have chosen one, close the screen and try shaking it.

- "Settings Each" mode
You can set screen colors, logos, and decorations individually.
We recommend using this mode after you get used to the "Collective Settings" mode! Choose your favorite color in the fixed colors, change the shake logo and decorations, and find your own favorite pattern!


■ Precautions
・Please be careful not to interfere with the organizer's performance when using it at an event. Please do not use smartphones, especially when they are not allowed to be used.
・Please make sure to attach an anti-drop device such as a strap to your smartphone to prevent it from falling out of your hand.
・Swinging the smartphone around without a fall prevention device attached may cause injury to others or damage the smartphone.
・When children are using the device, please be sure to use it with a parent or guardian and be aware of the safety of those around you.
