Cautions to Observe Prior to Charging Li-Ion Batteries

• Li-Ion chargers are designed exclusively for Li-Ion batteries. Ensure you have the correct charger for the battery chemistry and number of cells in series. To calculate cells, divide battery voltage by 3.6VDC (e.g., 14.4VDC battery has 4 Li-Ion cells).
• The charge voltage should correspond to the number of cells multiplied by 4.2VDC (e.g., a 4-cell Li-Ion battery typically charges at 16.8VDC). Note: Voltages are typical and may vary. Consult battery specifications if unsure.
• Ensure the battery specifications allow for the maximum charge current indicated on the charger.
• Ensure the battery specifications are suitable for the environmental conditions during charging.
• Never attempt to charge non-rechargeable batteries.
• Connect the charger to the mains ? before connecting to the battery. This minimizes sparks due to potential differences between terminals. Ensure charger terminals are not short-circuited and polarity is correct.
• Ensure correct polarity when connecting to battery terminals. Reverse polarity may cause a fuse to blow or render the charger useless.
• The charge cycle begins when the charger is connected to the mains.
• If the charger is disconnected from mains during a charge cycle, it will restart a new cycle upon reconnection.
• Recommended minimum and maximum battery capacity varies. Follow the battery manufacturer's datasheet and recommendations. 1C is the typical maximum current for Li-Ion cells (e.g., 1A for a 1Ah battery). For example, a 1A charger typically recommends 1Ah minimum capacity. Max capacity recommendations vary based on termination methods (e.g., C/40 for timers, 100x current detection for others).

To detach: Push down on the "Push" handle while pulling the product from the wall.

If not wall-mounted, the bracket can be used as a handle following the same procedure.

Explanation of Li-Ion Battery Charge Cycle

(See tables for methods for each charger model)

Charging Method A

• STEP 1 - CONSTANT CURRENT CHARGE: Connect charger to mains. Charger is in constant current mode, charging at maximum indicated current. LED is ORANGE ?. This allows rapid charging up to 80-95% capacity.
• STEP 2 - CONSTANT VOLTAGE CHARGE: Charger enters constant voltage mode, charging with decreasing current until it drops below the termination level. LED is ORANGE ?. Battery reaches full capacity.
• STEP 3 - CHARGE COMPLETE: LED is GREEN ?. Battery is fully charged. Charge current is zero. Battery voltage remains at Step 2 level. Charger returns to Step 1 if battery is used. A load exceeding cut-off current initiates a new charge cycle.

Diagram A Description:

The diagram shows three steps: Step 1 (CC Charge), Step 2 (CV Charge), and Step 3 (Charge complete).

• INDICATOR: ORANGE ? (Steps 1 & 2)
• INDICATOR: GREEN ? (Step 3)
• Charge Current: Starts high in Step 1, decreases in Step 2, and becomes zero in Step 3.
• Charge Voltage: Rises in Step 1, stays constant in Step 2, and drops to a standby level in Step 3.
• Cut-Off Current is indicated at the end of Step 2.

Charging Method B

• STEP 1 - CONSTANT CURRENT CHARGE: Connect charger to mains. Charger is in constant current mode, charging at maximum indicated current. LED is ORANGE ?. This allows rapid charging until battery voltage reaches a set level.
• STEP 2 - CONSTANT VOLTAGE CHARGE: Charger enters constant voltage mode with decreasing current. LED is ORANGE ?. When battery reaches 90-95% capacity, current drops, and LED changes to YELLOW ?, indicating near full charge. Constant voltage charge continues to full capacity.
• STEP 3 - CHARGE COMPLETE: LED is GREEN ?. Battery is fully charged. Charge current is zero. Battery voltage remains at Step 2 level. Charger returns to Step 1 if battery is used. A load exceeding cut-off current initiates a new charge cycle.

Diagram B Description:

Electromagnetic Compatibility

To prevent unsafe product situations, the EMC EN60601-1-2 standard has been implemented. This standard defines immunity levels and maximum emission levels for medical devices. Mascot medical devices have been tested and conform to IEC/EN 60601-1-2 (3rd & 4th editions), though special precautions may be necessary.

Mascot products are suitable for Domestic, Residential, Office, and Hospital environments, except in locations with high EM Disturbances (e.g., near High Frequency Surgical Equipment or Magnetic Resonance Imaging systems).

When used as specified, the product is expected to fulfill its essential performance (powering Medical Electrical Devices or charging batteries for them).

WARNING: Avoid using this equipment adjacent to or stacked with other equipment, as it may result in improper operation. If necessary, observe both units to ensure normal operation.

WARNING: Using accessories, transducers, or cables other than those provided by the manufacturer could increase electromagnetic emissions or decrease immunity, leading to improper operation.

WARNING: Portable RF communications equipment should be used no closer than 30 cm (12 inches) to any part of the power supply or battery charger, including cables, to prevent degradation of performance.

Guidance and Manufacturer's Declaration

Mascot products are intended for use in the specified electromagnetic environment. The customer or user should ensure it is used in such an environment.

These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people. Field strengths from fixed transmitters (e.g., base stations, radio broadcasts) cannot be predicted accurately. An EM site survey may be considered. If measured field strength exceeds applicable RF compliance levels, observe the Mascot product for normal operation. If abnormal performance occurs, re-orienting or relocating the product may be necessary.
