Figure 4: View with Unit Cover Removed
Link Bar must be unattached from dog silhouette (See Figure 3)
to completely remove unit cover.
The 9-volt battery in the radio receiver needs to be replaced periodically. If after use the
unit begins to "act up", a new 9-volt battery in the radio receiver unit will often return
the backing dog to normal operation.
If the dog backing unit does not stop at the up or down position
• First remove unit cover and reattach the link bar to dog silhouette see Fig 3.
• Verify that a new 9-volt battery is in receiver and the backing dog battery is fully
charged.
• Verify that the 3-pin connector is mated properly and locked in place.
• Verify that the rotating bar is properly tripping the limit roller (each end of the
rotating bar should trip the limit switch roller). If not, it needs adjusting. (See Figures 5
and 6.)
