OPERATION OF FLEXIBLE ARM
Your new LS-135 & LS-150 light has been carefully designed to give you
optimum performance to enable you to easily articulate and place the
light exactly where you need it. These design attributes include:
• The lamp has been offset at a 12° angle relative to the Luminaire
housing, allowing the physician an unobstructed view of the field
of interest.
• A pole to flexible arm joint that allows the flexible arm to be freely
rotated about the pole 270°.
• A flexible arm to Luminaire joint that allows rotation of the
Luminaire about the flexible arm 300°.
• A 24" flexible arm that allows you to easily articulate and hold the
Luminaire in an infinite number of positions.
Please use the following guidelines for proper articulation of the flexible
arm:
• The flexible arm should be articulated (bent), NOT TWISTED.
Twisting of the flexible arm beyond its rotation stops will
decrease the life of the arm and can cause it to lose its ability to
hold position.
• Failure of the flexible arm due to twisting may void the warranty.
Special Note: We recommend that you DO NOT acutely bend the
flexible arm as shown below.
