NOTE: If you use Set or Read Lock Levels to secure lists on the device, all settings can be modified
by anyone who can find their way to the Set Lock Level or Read Lock Level parameters.
Passwords
Enabling passwords provides an additional layer of security. With passwords enabled, you select a Lock
Level defining what users can view or set prior to entering a password. Then when the user enters the
password, the user has the permissions as were set in the Read Lock and Set Lock security Levels.
Enabling Passwords
Before you enable passwords, note that it is vital you save the password for future use in accessing
restricted Lists. You must determine a safe place to store your passwords outside of the device.
1. Go to
Operations — Factory — Lock
2. Scroll to and select
Password
Enable
, then select
On
.
3. Press the Left Arrow to go back to the Lock list, then scroll to select
Locked Access Level.
4. Use the slider to select the
Locked Access Level [1-5]
, which defines what users have access to prior to
entering a password. Refer to the Security Lock Levels table.
5. (This step is optional, and not recommended in most scenarios) Press the Left Arrow to go back to
Fac-
tory - Lock
, then scroll to Rolling Password and select Off or On. This configures the device to change a
Public Key Code every time power is cycled. This public key code is then used in a formula along with the
user or admin password to discern the real time password for the device.
Rolling Password Formula for user passwords: (Password x Public Key) Mod 929 + 70
Rolling Password Formula for admin passwords: (Password x Public Key) Mod 997 + 1000.
6. Press the Left Arrow to go back to the Lock list, then scroll to select
User Password.
7. Use the numeric slider to set the password. The default is 63, which you can keep or change. Be sure to
make note of this number and save it somewhere outside the device for future use.
This takes effect after a power cycle.
Once in effect, users must enter this password to gain access to the device beyond the Locked Ac-
cess Level set in step 4. After the password is entered, they will be subjected to the Read and Set Lock
Levels configured separately in
Read Lock
and
Write Security
(Refer to "
Changing List Set Lock
and Read Lock Levels
").
8. Press the Left Arrow to go back to the Lock list, then scroll to select
Administrator Password
. This is the
password you will need if you wish to change any future user passwords.
9. Use the numeric slider or +/- keys to set the password. The default is 156, which you can keep or change.
