Jumper X8 sets the control source of the LCD backlight. When jumper
assembled to position 1, external source is selected. When position 2
selected, internal (phone) control is selected.
Jumper X9 sets the current measuring ability on/off. If jumper is
assembled, internal (phone) control without current meter is selected. If
jumper has not been assembled, current measurement option is selected.
The current meter shall be placed between pins 19 and 20. Battery supply
comes from the phone.
Also it is possible to supply battery voltage to directly to UI–module. Then
the supply voltage shall be connected to pin 20. The jumper shall not be
assembled.
Jumper X10 sets the control source of the buzzer PWM signal. When
jumper assembled to position 1, external source is selected. When
position 2 selected, internal (phone) control is selected.
Note: The default setting for jumpers X7,X8 and X10 is position 2 and
jumper X9 is assembled.
