3.2.9 USB Cable Clamp Attachment/Removal
This clamp is used to prevent the USB cable connected to the USB Host Interface on the bottom of the PS-A
unit from being unplugged due to vibration or other causes.
Attachment
(1) Place the PS-A unit face-down on a flat surface as shown below. Your PS-A unit has four USB
connectors.
(2) As shown, insert the USB Cable Clamp’s band through the Bridge. Pass the USB cables through the
Cable Clamp’s band and securely tighten the clamp band around the cables.
• When using two or more USB ports, be sure to first connect one USB cable to the lower
USB connector, and then connect the second USB cable to the upper USB connector.
• When using only one of the USB ports, be sure to use the lower USB connector. This
allows you to securely clamp the USB cable in the cable clamp.
• Be sure the clamp is securely holding the USB cable’s plug and collar.
• Be sure the clamp is positioned as shown below, with the clamp pointing upwards - not to
the side. This is to keep the clamp from interfering with nearby connectors and their
cables.
