Passcode
The “P-WORD” function allows you to protect:
- the total acre count,
- pulses per 400 feet and
- width
settings with a 4-digit passcode. This prevents accidental
and malicious changes to those settings. As provided by
the factory, the passcode feature is disabled, and you
can modify those function values at any time.
Press the button until the “P-WORD” LED is lit. The
display reads either:
“
Ent ” (enter passcode) or
“ dIS ” (passcode disabled)
Enable and Set Passcode
The P-WORD display must show “ dIS ” in order to enable
and set a passcode on a unit which presently has no
passcode (see below for changing an existing
passcode).
Refer to Figure 8
Use the UP and DOWN buttons to select a passcode in
the range 0001 through 9999 (0000 disables).
Press button to accept the passcode. If the module
enters sleep mode before you press the button, the
passcode is not set.
Note: The protected function values remain unprotected
until the next time the module enters sleep mode.
Using a Passcode
If the P-WORD display shows “ Ent ”, a passcode must be
entered, or the protected function values cannot be
changed.
Refer to Figure 9
Enter the passcode using the UP and DOWN buttons.
When your passcode is displayed, press the
button to
test the passcode.
If the passcode is correct, you can change the protected
settings.
The protected settings are unprotected, and the
password remains viewable in the P-WORD display
function, until the module next enters sleep mode. When
button is next pressed, the passcode is again required
to change protected settings.
If the entered passcode is not correct, the protected
settings cannot be changed. When the “P-WORD”
function is selected again, “
Ent ” appears in the display.
