Sensitivities should only be reduced when there are no locatfons at which the Ferroguard Screener Beamn will stay green. There are two sensiCivify dials at the bottom of the Ferroguard Saeener, one which controls the amber threshold, and one which mntmis the red threshold. As standard 6oth dials will 6e set to 10 (most sensitive). You will have been supplied with a small saewdrivery this is can be used m rotate the sensitivity dials. I � f. � " '� � � There is a third dial which allows the user to tum on an audible alert which will sound when the beacon tums red If at your chosen location the beamn does not stay green then you can reduce the sensitiviTy by � following the instruc[ions below. � 1) Usingtheadjustmentscrewdnverpwvided, � rotate both the amber and red dials counter dockwise by one dick so they are set m 9. � 2) Press the screen bvtton, move back b' (2m) and observe the beacon and magnimde dlsplay- 3) If the beamn stays on green then the adjustment is mmplete. If you still see regular flickers of amber or red, then repeat steps 1 and 2(Turn 6oth dials to down 1 dick and observe) until you achieve steady green. If you find you have to adjust the sensitivities to b or below, please contact Metrasensfor advice. 15 AFi.nev�.... �.e,...i Ferroguard Screener 7 Appendix_B- Maintenance r �,� ,-�,,,�� Annualtc IingbyMehasensaPP/ovedFeimguardtechnicians. Metrasens or your bcal distribumr offer a rervice contract that indudes annual inspec[ion and testing. During inspection our approved technlcian will ensure the rystem Is working to Its full specification. Many hospitals adopt this as thelr only formal procedure and do not conduct their own testing, particulady if they have a 4ixed regular MRI staff. The reason is that regular staff members very qulckly leam the behavlors of Fermguard - and in particular how it responds to certain stimuli from ierromagnetic o6jects in the vicinity. A rystem failure would be immediately obvious to them. Less obvious would be a slow reductlon in sensltivity - in (acY this may not be at all apparent unless It was faldy severe. However, this mode of failure has never o¢urred in practice so far. We view this option as being the minimum acceptable testing regime. Irrespective o( further testing options Metrasens recommends all Ferroguard sites to have this service connact. .,- ._„_...p �`� Fo da ly checking Metasere remmmend a short mutine at the begmning oi a shlk or the beginning oithe day m mnfirm everything is OK and for the staH to check themselves.
