5.3. ACCESS IN THE CASE OF LOSS OF MASTER KEY/
STORAGE OF NEW MASTER KEYS
It is always possible to access a device, even without the MASTER keys, provided you have a blank key, i.e.
a key that has never been stored as user key on that device.
Proceed as follows:
— remove the front cover to access the confi guration button.
press the confi guration button (5) briefl y;

— press the confi guration button again briefl y;
— present the blank key which will be stored as MASTER key in addition to or in replacement of (if 3 have
already been stored) of the MASTER keys present.
— present this new MASTER key for at least 7 seconds so as to restore normal functioning.
— use this new MASTER key to access the device.

5.3.1. ACCESS PASSWORD

Access from the confi guration button can be protected using a 3-digit password.
When a password is entered in the device, the confi guration button can be accessed subsequently only
re-entering the password.
WARNING:
If all the MASTER keys of a device equipped with password are lost and you have forgotten the
password, IT IS IMPOSSIBLE TO ACCESS DEVICE PROGRAMMING. In this case, get in touch with
the URMET Technical Assistance Center in the area directly which will eliminate the password
without deleting any of the user keys.
The password can be set on any device without password (therefore on any device that leaves the factory).
Once the password has been entered, it cannot be modifi ed.
It can be deleted only using the complete memory reset procedure (see below): IT IS ADVISABLE
THEREFORE TO ENTER THE PASSWORD BEFORE STARTING TO STORE THE USER KEYS SO THAT
THIS CAN BE DELETED IN THE CASE OF ERRORS DURING THE ENTRY PHASE.

— Press and release the confi guration button again twice so as to set the other two digits. Now the display
will show the confi gured password. Press the confi guration button briefl y to confi rm the password. In
this way, you will access the MASTER key programming menu from which you can exit using a MASTER
key as described in the 'Key master key storage'.
