3. Istruzzjonijiet Operattivi
3.1 Informazzjoni dwar id-Displej tal-LCD
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.

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:
- Agħfas il- C button to select the desired slot.
- Agħfas u żomm il- V button to enter manual setting mode.
- Uża l- C button to cycle through options (charging voltage, charging current).
- Uża l- V buttuna biex taġġusta l-valur magħżul.
- Confirm your selection by pressing and holding the V button, or wait for the setting to automatically apply after a few seconds of inactivity.

4. Manutenzjoni u Kura
- Żomm il-ċarġer nadif u niexef. Uża drapp artab u niexef biex timsaħ il-wiċċ.
- Evita li tesponi l-ċarġer għal temperaturi estremi, dawl tax-xemx dirett, jew umdità għolja.
- Do not attempt to disassemble or modify the charger, as this will void the warranty and may cause damage.
- Aħżen il-ċarġer f'post frisk u niexef meta ma tkunx qed tuża.

5 Issolvi l-problemi
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.
- Batterija bil-ħsara: 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 Charger Not Powering On
- Kun żgur li l-kejbil USB-C huwa konness sew kemm mal-ċarġer kif ukoll mas-sors tal-enerġija.
- Try a different USB-C cable and/or power adapter to rule out faulty accessories.
- Ivverifika li s-sors tal-enerġija jaħdem.
5.3 Batteriji Mhux Qed Jiċċarġjaw
- Iċċekkja l-polarità tal-batterija. Kun żgur li l-batteriji huma mdaħħla sew.
- 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.
