VM700A Option 01 (NTSC) & Option 11 (PAL) User Manual
To Enable or Reset the Password Function. Turn off the VM700A and remove the
holding screws for the left side panel. Slide the left side cover of the VM700A
back to expose the 6-section DIP switch on the A5 circuit board. To enable
Password, set position 3 (from the front of the DIP switch) UP. When power is
turned on again, the Password function is enabled, and you can set a password
using the procedure given previously.
To either reset the password, if it should become unknown for some reason, or
disable the function, set position 3 of the DIP switch DOWN, turn on the
VM700A, and let it complete its power-up routine. The Password function is
now disabled, and the unknown password is visible in the Password file and may
be edited.
To re-enable Password, turn off the VM700A and set position 3 of the DIP
switch UP. Close the side panel and replace the holding screws for the panel.
To Change the Current Password. Select (touch) the Password file icon.
Type in the current password and press Done or Return.
Touch the current password.
Type in the new password (up to 15 characters).
Press Return or Done and select the Update & Exit soft key to put the new
password into effect, or press Cancel or No Change & Exit to keep the old
password.
When the Password function is first enabled, the default password is null; no
password is needed to Update & Exit, Rename, Delete, or Create a directory or
file. Once a password is set, it will be requested when you attempt to Update &
Exit, Rename, Delete, or Create a directory or file (i.e., every time you change
the contents of non-volatile memory). If the correct password is entered, the
requested action is completed. The VM700A allows three unsuccessful attempts
to enter a password before displaying the message No Password, no access! and
canceling the requested action.
Changing the password to null has the same effect as disabling the Password
function with the DIP switches.
File(s) in the Selected Measurements directory contain a list of all the measure-
ments Auto mode can perform. They allow you to select a subset of measure-
ments for the VM700A to perform. The current Selected Measurements file
provides Auto mode with a list of measurements to perform, while the current
Auto Limit file provides the limits at which those measurements generate
Caution and Alarm messages.
The Selected Measurements System Default file is the only file available for
selection when the instrument is shipped. This file cannot be edited and all the
