4.13 DIGITAL DISPLAY
When connected to a battery, the digital display can be used to indicate the battery's voltage. When not
connected to a battery, the digital display can be used to indicate the percent of charge or the voltage of
the jump starter's internal battery.
To check the internal battery's charge status, make sure the rotary switch is in the OFF position, then
press the display button on the front of the jump starter. The digital display will show the battery's percent
of charge. A fully charged battery will read 100%. Charge the internal battery if the display shows it is
under 100%.
NOTE: The internal battery's percent of charge is most accurate when the jump starter has been
disconnected from all devices and charging sources for a few hours.
To check the voltage level of the jump starter's internal battery, make sure the clips are attached to their
plastic storage holders and not touching each other, and then turn the rotary switch to the 12V position
(12V or 24V position on DSR160). The display will indicate the battery's voltage.
To check the voltage level of the vehicle's battery, make sure the switch in the OFF position, then
connect the clips to the vehicle's battery. The display will indicate the battery's voltage.
