Application lock function

You can use the application lock to prevent third parties from operating

the projectors using EMP Monitor and from changing settings without

authority. Opening and closing EMP Monitor and status monitoring can

still be carried out even when the application lock is applied.

In addition, when a password has been set, the password must be entered

in order to cancel the application lock. This ensures that the application

lock can not be easily cancelled, and thus improves system security.

Switching application lock between enabled and

disabled

Procedure

Select "Application lock" from the Tool menu.

The application lock will be enabled and no operations will be possible

other than opening and closing EMP Monitor and disabling the

application lock.

Procedure

Select "Application unlock" from the Tool menu.

The password entry window will be displayed, so enter the

set password and then click "OK".

If no password has been set (default setting), click OK without en-

tering a password. It is recommended that you enter a password in

order to strengthen security.

The application lock will be cancelled and operations can be carried

out as normal.

Carry out the following operations while application lock is cancelled.

Procedure

Select "Environment setup" from the Tool menu.

The Environment setup window will be displayed.

Select "Change the application lock password".

Enter the password in both the "New password" and "New

password (confirm)" boxes and then click "OK".

The password can be up to 16 bytes in length. Single-byte alphanumeric

characters can be used.
