It is important to handle the equipment correctly and with care. The microphone acts as a counterweight to help stabilise the Rode PSA1 Studio Arm, which means that any forceful adjustments could cause the microphone to tip over and cause damage.
Only attempt to adjust the arm using the adjustable handles
Hold the arm with both hands when using the handles
Do not attempt to remove the clamp from its original position
