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 DSR115). 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.

CHARGER LED INDICATORS
POWER (green) LED lit: The charger is connected to AC power.
CHARGING STATUS LED (green) pulsing slowly: The charger is charging the jump starter’s internal
battery, or the battery is fully charged and the charger is in Maintain mode.
CHARGING STATUS LED (yellow/orange) flashing rapidly: The charger has detected a problem
with the battery. See Troubleshooting for more information.
BAD BATTERY (red) LED lit: The charger has detected a problem with the battery.
SeeTroubleshooting for more information.
5. CHARGING THE INTERNAL BATTERY OF THE JUMP STARTER
IMPORTANT! CHARGE IMMEDIATELY AFTER PURCHASE, AFTER EACH USE AND EVERY 30 DAYS,
TO KEEP THE UNIT’S INTERNAL BATTERY FULLY CHARGED AND PROLONG BATTERY LIFE.
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%. Complete charging may take up to 48 hours.

GROUNDING AND AC POWER CORD CONNECTIONS
IMPORTANT: Only use the charger that was included with the jump starter to charge the internal battery of the
jump starter. Using a different charger could result in personal injury or property damage.
WARNING! RISK OF ELECTRIC SHOCK OR FIRE.
This battery charger is for use on a nominal 120V circuit. The plug must be plugged into an outlet
that is properly installed in accordance with all local codes and ordinances. The plug pins must fit the
receptacle (outlet). Do not use with an ungrounded system.
DANGER. Never alter the AC cord or plug provided – if it does not fit the outlet, have a proper outlet installed
by a qualified electrician. An improper connection can result in a risk of an electric shock or electrocution.
An extension cord should not be used unless absolutely necessary. Use of an improper extension cord
could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
• That the pins on the plug of the extension cord are the same number, size and shape as those of the plug
on the charger.
• That the extension cord is properly wired and in good electrical condition.
• That the wire size is large enough for the AC ampere rating of the charger, as specified:
