Operating Instructions; Important - Schumacher DSR PROBOOSTER DSR103 Manual Del Usuario

Maintaining the Battery
The SC3DSR maintains 12V batteries,
keeping them at full charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods

8. OPERATING INSTRUCTIONS

IMPORTANT: READ INSTRUCTIONS
BEFORE CONNECTING THE OUTPUT
VOLTAGE SELECTOR.
8.1 Voltage detection system
Your Booster is equipped with a voltage
detection system. After the connection of
the clamps on the battery terminals of the
vehicle, LEDs will indicate its voltage, as
follows:
• The green LED next to the 12V
connector lights up when the voltage
detected by the Booster is between 3V
and 14,4V.
• The orange LED next to the 24V
connector lights up when the voltage
detected by the Booster is over 14,4V.
NOTE: If your vehicle does not start when
the Booster is connected in 12V, your
vehicle may start in 24V:
• When its voltage is under 14,5V
• If you connected the Booster on the
wrong vehicle's battery
8.2 Detection of 24V
Detection of 24 volt on a vehicle where
the cables are not visible or when the
batteries are located on both sides of
the engine bay (construction, agriculture,
military or other large type engines).
Use a voltmeter in DC position:
Connect the negative to the mass of the
vehicle and the positive to the positive of
a battery.
• If the voltmeter indicates 12V, you are not
on the right battery.
• If the voltmeter indicates 24V, you are on
the right battery.
8.3 Selecting the voltage
1. Determine voltage of vehicle battery.
(Refer to the vehicle instruction manual.)
2. Make sure to plug the output voltage
selector into the correct connector.
of time. However, problems with the
battery, improper connections or other
unanticipated conditions could cause
excessive current draws. Occasionally
monitoring your battery and the charging
process is recommended.
8.4 Jump Starting a Vehicle Engine
IMPORTANT: Using the booster without a
battery installed in the vehicle will damage
the vehicle's electrical system.
IMPORTANT: Do not use the booster while
charging its internal battery.
WARNING! A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE RISK
OF A SPARK NEAR THE BATTERY:
1. Turn the vehicle's ignition OFF before
making cable connections.
2. Position the DC cables to reduce the
risk of damage by the hood, door and
moving or hot engine parts.
NOTE: If it is necessary to close the
hood during the jump starting process,
ensure that the hood does not touch
the battery clips or cut the insulation of
the cables.
3. Stay clear of fan blades, belts, pulleys
and other parts that can cause injury.
4. Check the polarity of the battery posts.
The POSITIVE (POS, P, +) battery
post usually has a larger diameter
than the NEGATIVE (NEG, N, -) post.
5. If the batteries are side by side:
Connect the red clamp (+) to the
positive terminal (+) of the battery,
and then connect the blue clamp (-) to
the negative (-) terminal of the other
battery.
6. If the batteries are on both sides of
the vehicle: Determine which post of
the battery is grounded (connected)
to the chassis. If the negative post is
grounded to the chassis (as in most
vehicles), see step A. If the positive
post is grounded to the chassis, see
step B.
