Take 2 batteries from the battery charger in the control room and put them in both the PPU (3) and VCG (4) unit, even if you only use PPU. You may leave the VCG unit in the closet if you don't use it.
Place the respiratory sensor (1) horizontally +/- 5 cm above the navel of your subject and secure it with the Velcro band.
Put the finger clip (2) on the left ring finger. Put the side with the light on the opposite side of the finger nail.
Note: For those of you who use the Philips MR Physiology recording system to measure and analyze VCG and respiratory signals, it is good to know that MR scanners with wireless VCG devices have a different sampling frequency than wired systems. Philips reports the sampling frequency of current wireless systems to be 496Hz. Based on gradient signals in the log files a rate of 496.03Hz has been reported (roughly a 0.2s difference on an hour measurement). The frequency of wired systems (7T!) is 500Hz. In most use cases this difference is negligible within fMRI trials, but the time difference can vary significantly over longer periods of time.
