Additional Notes
• The SECURITY GUARD system requires any
control (other than the one with the assigned
4-digit security code) to enter the security
code before the snowplow can be activated.
Once the security code is established, the
SECURITY GUARD system recognizes that a
control with the same security code is attached,
and does not require a manual unlock to activate
the snowplow. The system will recognize the
control as "safe" and will automatically unlock.
• In the event that a snowplow is locked and cannot
be manually unlocked or reset, contact your
Authorized Distributor.
• REMINDER: Record your security code for future
reference.
Manual Unlock
If the SECURITY GUARD™ system is activated
and you are using a control with a different 4-digit
code than the established security code, you will be
required to manually enter the 4-digit security code
before operating a locked snowplow.
1. Turn the vehicle ignition to the "ON" or
"ACCESSORY" position.
2. Turn the control to the "ON" position.
3. The POWER light will
fl
ash rapidly, indicating that
the snowplow is locked.
4. Enter the 4-digit security code.
5. After entering the correct security code, the
POWER light will change from
fl
ashing rapidly to
a solid light to indicate the snowplow has been
successfully unlocked.
NOTE: If the plow/vehicle electrical connection
is lost or disconnected, the SECURITY GUARD
system will reset, requiring any control that is not
programmed with the established 4-digit security
code to manually re-enter the security code to
activate the snowplow.
Clearing an Established 4-Digit Security Code
1. Turn the vehicle ignition switch to the "ON" or
"ACCESSORY" position.
2. If the snowplow is locked (the control POWER light
will be
fl
ashing at a fast rate), unlock the snowplow
by following the Manual Unlock procedure.
3. Turn the control to the "OFF" position. Verify that
the power indicator is OFF.
