Operation

This device must be powered to preserve the vehicle’s saved settings. You may use
a 12V battery or a 9V “radio” battery to supply this power (neither one included).

1. If using a 12V battery: connect the Red alligator clip to the positive (+) pole
of the battery and the Black alligator clip to the negative (-) pole of the
battery. Plug connector into the Jack on side to the tool. WARNING: 12V
lead/acid batteries can be very dangerous. Always wear safety gloves and
ANSI-approved safety goggles when working with 12V lead/acid batteries.
Do not allow battery to overheat.

If using a 9V battery: open the battery cover of the device, and install a new 9V
battery, attaching the battery plug to the battery. Close the battery compartment
cover.

2. Using either a spare 12V battery or an installed 9V battery, two green LED
lights will illuminate indicating the device has power. Do not short out the
12V Lighter adapter on a metal surface, it is now powered.

3. Be sure that vehicle ignition and all accessories, including lights, radio,
interior light, etc. are OFF Before using this device. If any powered item is
ON, the memory device may fail.

4. Press and hold the Red Button on the device while inserting the plug into the
vehicle cigarette lighter outlet.

5. One Green LED will now glow, indicating a good connection through the
vehicle cigarette lighter outlet.

NOTE: On some vehicles, the key must be left in the “Accessories” setting
for the cigarette lighter outlet to be active.

6. Release the Red Button. Both green LED lights will now glow indicating a
good connection.

7. You may now disconnect the vehicle 12V battery. Keep in mind that the
temporary power supply will only last as long as the battery used.

8. When the work is finished, reconnect the vehicle 12V battery.

9. Press and hold the Red Button on the Memory Saver while you remove the
Memory Saver device from the cigarette lighter outlet. Do not leave the unit
connected after use.

Green LED’s do not light when connected to 12V battery or 9V battery
installed. Possible causes: Battery has no charge, or faulty connection.

Solution: Check the charge of the battery and recheck the battery
connection and polarity.

Green LED’s do not light even though battery is charged and properly
connected. Possible Causes: Fuse is blown or device is damaged. Solution:

Test and/or replace 3 Amp fuse. Only replace fuse with same kind and
amperage fuse

Single Green LED does not glow after device is connected to cigarette
lighter outlet in step 4, page 4. Possible cause: Cigarette lighter outlet is

not active or not in good condition. Solution: Try moving ignition key to
“accessory” position and repeat steps 3-5 on page 4. If this still doesn’t
work, inspect the condition of the cigarette lighter outlet. Try the cigarette
lighter. With the vehicle battery disconnected, clean the outlet. (NOTE:
