*Note: Power to the MJS-84 can be supplied in three ways; 5V to 9V connected to the jack
or ‘DC IN’ banana socket or Vbat direct (3.2V to 4.2V) via the ‘METER’ connector (using
this method the jumper must be removed otherwise excessive current will be drawn
through the jig current sink. See Figure 3).

A charger can be connected to the charger jack, ensure that the phone supply is con-
nected to the ‘DC IN’ and that the jumper is also connected.
