1.2.14 Service Shell
The Service Shell is for service purposes only.
The Service Shell lets users have access to internal functions of the device. When you need
assistance with your device, the service personnel use the Service Shell to monitor internal
conditions for example, the switch or CPU registers.
Do not execute internal functions without service technician instructions. Executing internal
functions such as deleting the content of the non-volatile memory (
NVM
) possibly leads to
inoperability of your device .
