3. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
3.1 എൽസിഡി ഡിസ്പ്ലേ വിവരങ്ങൾ
The LCD display provides real-time information about the charging process for each slot. This includes battery health, charging status, charging mode, voltage, current, and charged volume.
ചിത്രം 3.1: വിശദമായത് view of the UMS4 LCD display, showing various charging parameters such as charged volume, charging time, charging current, battery voltage, charging mode, cut-off voltage, and battery type.
3.2 Automatic and Manual Mode Selection
Upon battery insertion, the UMS4 automatically detects the battery type and capacity, then selects the appropriate charging current and voltage. For LiFePO4 and 3.8V Li-ion batteries, manual selection is required.
The charger automatically selects between three charging modes: Constant Current (CC), Constant Voltage (CV), and -dV/dt, based on the battery type and capacity.

3.3 Adjusting Charging Parameters
To manually adjust charging parameters:
- അമർത്തുക C button to select the desired slot.
- അമർത്തിപ്പിടിക്കുക V button to enter manual setting mode.
- ഉപയോഗിക്കുക C button to cycle through options (charging voltage, charging current).
- ഉപയോഗിക്കുക V തിരഞ്ഞെടുത്ത മൂല്യം ക്രമീകരിക്കുന്നതിനുള്ള ബട്ടൺ.
- Confirm your selection by pressing and holding the V button, or wait for the setting to automatically apply after a few seconds of inactivity.

5. പ്രശ്നപരിഹാരം
5.1 "EE EE" Error Message
If the display shows "EE EE", it indicates one of two conditions:
- Over-discharged IMR Battery: The battery is severely discharged. The UMS4 has an over-discharged battery activation feature that attempts to revive such batteries. If the error persists, the battery may be beyond recovery.
- കേടായ ബാറ്ററി: The charger has detected a damaged or faulty battery. Remove the battery immediately and dispose of it safely. Do not attempt to charge damaged batteries.

5.2 ചാർജർ ഓണാകുന്നില്ല
- Ensure the USB-C cable is securely connected to both the charger and the power source.
- Try a different USB-C cable and/or power adapter to rule out faulty accessories.
- പവർ സ്രോതസ്സ് പ്രവർത്തിക്കുന്നുണ്ടെന്ന് ഉറപ്പാക്കുക.
5.3 ബാറ്ററികൾ ചാർജ് ചെയ്യുന്നില്ല
- Check battery polarity. Ensure batteries are inserted correctly.
- Clean the battery contacts and charger contacts with a dry cloth to remove any dirt or residue.
- Ensure the battery type is compatible with the UMS4 charger.
- If charging LiFePO4 or 3.8V Li-ion batteries, ensure manual mode selection for voltage is correctly set.
