IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS – This manual will show you how to use your
memory saver detector safely and effectively. Please read, understand and
follow these instructions and precautions carefully, as this manual contains
important safety and operating instructions.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION.
FOR THIS REASON, IT IS IMPORTANT THAT YOU FOLLOW THESE
INSTRUCTIONS EACH TIME YOU USE THE MEMORY SAVER DETECTOR.
WARNING: Pursuant to California Proposition 65, this product contains
chemicals known to the State of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.
•Read the entire manual before using this product. Failure to do so could
result in serious injury.
•Use the memory saver detector in a well-ventilated area.
•This memory saver detector is not intended for use by children.
•Do not expose the memory saver detector to rain or snow.
•Do not operate the memory saver detector if it has received a sharp blow, been
dropped or otherwise damaged in any way; take it to a qualied service person.
•Inspect the battery for a cracked or broken case or cover. If the battery is
damaged, do not use the memory saver detector.
•Do not disassemble the memory saver detector; take it to a qualied service
person when service or repair is required. Incorrect reassembly may result in
a risk of re or electric shock.
•Follow these instructions and those published by the battery manufacturer
and the manufacturer of any equipment you intend to use in the vicinity of the
battery. Review the cautionary markings on these products and on the engine.
PERSONAL SAFETY PRECAUTIONS
•Wear complete eye protection and protective clothing when working near
lead-acid batteries. Always have someone nearby for help.
•Have plenty of fresh water, soap and baking soda nearby
for use, in case battery acid contacts your eyes, skin or clothing. Wash
immediately with soap and water and seek medical attention.
•If battery acid comes into contact with eyes, ush eyes immediately for at
least 10 minutes and get medical attention.

•3•
•Neutralize any acid spills thoroughly with baking soda before attempting to
clean up.
•Remove all personal metal items from your body, such as rings, bracelets,
necklaces and watches. A lead-acid battery can produce a short circuit
current high enough to weld a ring to metal, causing a severe burn.
•Never smoke or allow a spark or ame in the vicinity of the battery or engine.
USING THE MEMORY SAVER DETECTOR
Use the memory saver detector cable to save the vehicle’s on-board
diagnostic computer settings (radio programs, diagnostic codes, etc.) while the
battery is disconnected from the vehicle during repair or maintenance.
NOTE: Some vehicle manufacturers do not allow the use of a memory
saver through the OBDII. Consult the vehicle manufacturer before use, to
determine if a memory saver is acceptable for use on the vehicle.
1. Make sure that the power source used is greater than or equal to 12VDC.
If using a portable battery device, make sure it is fully charged.
2. Turn off the vehicle, remove the key, and make sure all accessories are off.
WARNING: Verify all vehicle accessories are OFF (fan, interior lights, etc.).
Headlights must be in OFF position, not AUTO position. To prevent overloading
of a vehicle fuse, OBD-L fuse or other vehicle damage, do not use the memory
saver through the OBDII port if the vehicle’s current draw is 4 amps or more
when the vehicle is in a KEY OFF condition (use an amp clamp to measure
the amperage draw). If unable to measure the vehicle’s current draw, turn the
vehicle’s key to the OFF position and wait 25 minutes. This ensures that all
retained accessories are in a power OFF state (for example: fan, headlights, etc.).
3. Connect the 12V power plug of the OBD-L to your 12V DC power supply.
Make sure plug is rmly in place. The yellow CONNECTED LED in box #1
will light, indicating a good connection.
WARNING: Do not connect the 12V power plug of the
OBD-L into the power outlet within the same vehicle
from which you are removing the battery.
4. Connect the OBD-L 12V OBD diagnostic connector
to the vehicle’s OBD plug. Make sure the connector
is fully engaged. The yellow CONNECTED LED in
box #2 will light, indicating a good connection.
5. Verify that the green PROCEED LED in box #3
is lit, indicating you may disconnect the vehicle’s
battery. If the red DO NOT PROCEED LED in box
#3 lights, do not disconnect the vehicle’s battery;
disconnect the OBD-L and check the internal fuse
or contact a qualied service personnel for electrical
system repair.

6. Disconnect the vehicle’s battery cables and cover the positive and
negative cables with an insulator, such as electrical tape. This prevents
the connectors from touching metal, each other, or the chassis and
causing a short circuit, due to the vehicle’s electrical system receiving
power through the OBD connection.
WARNING: When working with the vehicle’s battery, review all of the battery
manufacturer’s safety instructions, warnings and directives regarding battery
disconnection, removal and replacement.
7. Remove the old battery and put the new battery into position.
8. Remove the insulator from the positive cable and connect it to the positive
terminal of the new battery.
9. Remove the insulator from the negative cable and connect it to the
negative terminal of the new battery.
10. Once the new battery is connected, unplug the memory saver’s OBD
connector from the vehicle’s OBD plug and disconnect the 12V DC plug
from the 12V power supply.
FUSE REPLACEMENT
The 12V power plug adaptor operates with a supplied 5A 250V glass fuse.
1. Access the fuse compartment by turning the tip of the adaptor in a
counterclockwise direction.
NOTE: The fuse is spring-loaded and caution must be taken to ensure that the
spring does not “y out” of the end of the fuse compartment when it is opened.
2. Remove the fuse and replace it with one of the same type and rating.
3. Close the adaptor by turning the tip in a clockwise direction.
