two conditions: {1) this device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 ofthe FCC Rules. These limits are designed toprovide reasonable protection against harmful
interference when the equipment is operated in acommercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in aresidential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his/her own expense.
How To Use
Charging Modes.
The Genius2D has two (2) automatic modes, and will begin chargin~ when both the battery and power are connected. Do not operate
the charger until you con~rm the Genius20 charger is compatible with your battery type and voltage. Below is a brief description:
Mode
Standby
12V
NORM
Explanation
The charger is connected to AC power but no battery is detected, and the charger is not charging. Energy Save is
activated during this mode, drawing microscopic power from the electrical outlet.
-----------~-----~------~
For charging 12-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free, Calcium batteries and AGM.

On-Board Mounting.
Mount the charger near the battery, ensuring the cables and charger are secure and away from any moving parts {eg. fan blades, belts,
pulleys}. Secure the provided mounting bracket to the vehicle's chassis using the two included self-tapping screws. For best results,
mark the position using the bracket, and pre-drill two small pilot holes. Once the bracket is secured, use the velcro strap to secure the
Genius20 in place.
Connecting to the Battery.
Do not connect the AC power plu~ until all otherconnections are made. Identify the correct polarity ofthe battery tenninals on the
battery. Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for anegative
ground system {most common}. Ifyour vehicle is a positive ground system {very uncommon), follow the below instructions in reverse
order.
1.) Connect the positive {red) eyelet terminal connector to the positive (POS,P,+) battery tenninal.
2.) Connect the negative {black) eyelet terminal connector to the negative {NEG,N,-) battery terminal.
3.) Connect the battery charger's AC power plug into asuitable electrical outlet.
Begin Charging.
1 .} Verify the voltage and chemistry of the battery.
2.) Confinn that you have connected the eyelet tenninal connectors properly and the AC power plug is plugged into an electrical outlet.
3.) All LEDs will flash momentarily, then the charger will begin charging without user intervention.
4.) The charger can now be left connected to the battery at all times to provide maintenance charging.

Understanding Charge LEDs.
The charger has one (1) Charge LED. This Charge LED indicates the connected battery(s} state-of-charge (SOC}. See the explanation
below:
LED
Pulsing Red LED
Solid Green LED
Pulsing Green LED
Explanation
The Red Charge LED will slowly pulse "on" and "off" when the battery is less than 75% fully charged.
When the battery is 100% charged, the Charge LED will be solid green.
The Green Charge LED will slowly pulse "on" and "off'' when the battery is between 75% and 100%
charged and dunng battery optimization charging. It is normal for optimization charging to occur on
a regular basis after the battery is fully charged.
Understanding Advanced Diagnostics.
The Error, Hot, and Standby LEDs together shall indicate error conditions shown in the table below:
Error Reason/Solution
Error LED

Reverse polarity. Reverse the battery connections. Or battery voltage is too low for charger
to detect.
Charger is outside ofits safe operating temperature and is not charging. Allow charger to cool down.
Battery will not hold a charge. Have battery checked by a professional.
Possible battery short. Have battery checked by a professional.
Battery voltage is too high for the selected charge mode. Check the battery.

The estimated time to charge a battery is shown below. The
size ofthe battery (Ah) and its depth ofdischarge (DOD) greatly
affect its charging time. The charge time is based on an average
depth of discharge to a fully charged battery and is for reference
purposes only. Actual data may differ due to battery conditions.
The time to charge a normally discharged battery is based on
a50% DOD.
