The password may be changed at this time by keying in
eight numbers on the front panel keypad. (The MODEL
2500 accepts prefixed zeros as discrete, which means the
instrument requires all eight digits of a number such as
00000004 in order to interpret the number 4 as the
password.) When the new password has been keyed in,
press the ENTER key. The keyboard now can be
unlocked for data entry only with the new password.
The password cannot be retrieved once entered, and
should be recorded in a secure location.
Changing values in the Model 2500 system may
activate alarms, which must be cleared before
placing the unit in service.
