Changing the Passcode
To change an existing passcode, first enter the existing
password as described above in ““Using a Passcode””.
Refer to Figure 54
While still in the PASS function display, select a new
passcode using the UP and DOWN buttons in the PASS
display.
Press and hold the FUNC button until the “ SEt ” (setting
password) appears in the display. Release the FUNC
button. The number in the display is your new password.
Be sure to record it.
To disable the passcode, set the new password to 0000
(press and hold both UP and DOWN to do this quickly).
Press and hold the FUNC button until “
diS ” (passcode
disabled) appears in the display.
If the passcode is forgotten, it can be disabled by
removing the batteries. In rental or managed commercial
operations, it is recommended that a tamper-evident seal
be affixed to the rear plate of the acre counter (securing
the battery compartment).
Battery Replacement
The battery operated acre counter uses 3 AA-size
alkaline batteries. Although the batteries typically last
between 5 and 10 years, they should be inspected
annually, as low batteries can leak corrosive chemicals,
and damage the electronic acremeter.
If battery replacement is needed, the acre counter
displays “
LObA ” (low battery).
For battery inspection or replacement, dismount the acre
counter from the implement and remove the 4 screws on
the back of the case. This will separate the housing from
the rear plate. Replace the batteries with 3 high quality
AA alkaline batteries.
Note: The module is dust and splash resistant, but under
no circumstance should it be submerged in any
conductive, corrosive or flammable liquid.
