== What it settles == * The current limits used on the wiki's Series 3 and 3a troubleshooting pages: the table on printed p. 19 gives maximum (and typical) standby and on-and-idle currents for the Series 3 and for 256K/512K, 1 MB and 2 MB Series 3a machines.<ref name="sm-19">''Series 3a Service Manual'', p. 19 (PDF p. 25), "Series 3/3a Current Levels".</ref> * Two LCD versions were fitted, Seiko with positive polarity and Hitachi with negative polarity, and few non-English machines have the Seiko module.<ref name="sm-6">''Series 3a Service Manual'', p. 6 (PDF p. 12).</ref> * Psion recommends replacing the battery wires whenever a machine is taken apart, because they flex every time the case is opened and closed, and gives the routing of the wire through the battery moulding.<ref name="sm-16">''Series 3a Service Manual'', p. 16 (PDF p. 22), "Battery Wire Assembly".</ref> * TAB LCD hinge springs are coloured blue and non-TAB springs black.<ref name="sm-15">''Series 3a Service Manual'', p. 15 (PDF p. 21).</ref>
