Transmitter-crippling device

The Transmitter-crippling device is a device invented by Ray which he planned to use to disable the transmitter's signal. The device made its debut in Chapter 28 of the The Promised Neverland series.

Jailbreak Arc
When Norman and Ray visited an injured Emma in their orphanage's infirmary, Ray gave Norman the transmitter-crippling device he has made, and instructed him to use it to disable the transmitter in his ear in order for him to escape Grace Field by himself without the transmitter's disturbance. Ray revealed how the device he made is created using parts of the gifts he has received from Isabella over the past couple of years, such as the instant camera he got from her a few days ago.undefined Norman placed the device into his pocket as he proceeded to climb up the wall using a bundle of ropes. But due to the steep cliff which lies behind the walls, he could not use the device. He then went back to Grace Field, returning the device back to Ray.undefinedundefined

Usage
A few days before Norman's shipping date, Ray gave him the transmitter-crippling device he created and adviced him to use it to aid his escape. Ray commented how he created it out of parts of the gifts he has been receiving from Isabella over the past 5 years of being her spy. Several noticeable gifts Ray has assembled to make it are an ipod, a nutcracker, a toy tank, a radio, a handheld console and the instant camera's strobe. Ray also explained how it can be used by placing it near the back of the ear where the transmitters are implemented, the device will cripple the transmitter and prevents Isabella's radar from receiving its signal.undefined
