3. Setup and Initial Charging

Upon delivery, your EMPIRE EPP-FNB57 battery is not fully charged. For optimal performance and battery longevity, it is crucial to perform an initial charge.

1. Initial Charge: Recharge the battery overnight (approximately 12-16 hours) before its first use. Use a compatible Yaesu/Vertex charger designed for Ni-CD batteries.
2. Inserting the Battery: Align the battery with the battery compartment on your Yaesu/Vertex two-way radio. Slide the battery into place until it clicks securely. Ensure it is firmly seated to maintain proper electrical contact.
3. Removing the Battery: To remove, locate the battery release latch (if present on your radio model), depress it, and slide the battery out.

4. Operating Instructions

Once the battery is properly installed and charged, your radio is ready for operation.

• Powering On/Off: Refer to your specific Yaesu/Vertex radio's user manual for instructions on powering the device on and off. The battery provides the necessary power for the radio's functions.
• Battery Life: The actual operating time will vary depending on your radio model, transmission power, usage patterns (transmit/receive/standby ratio), and environmental conditions.
• Charging During Use: Some radio models may support charging while the radio is in operation. Consult your radio's manual for this feature.

5. Maintenance and Storage

Proper maintenance and storage will extend the life of your Ni-CD battery.

• Regular Charging: Ni-CD batteries benefit from being fully discharged periodically before recharging to prevent the "memory effect." However, avoid prolonged deep discharge, which can damage the cells.
• Charging Environment: Charge the battery in a well-ventilated area at room temperature. Avoid charging in extremely hot or cold conditions.
• Cleaning: Keep the battery contacts clean using a dry, lint-free cloth. Dirty contacts can interfere with charging and power delivery.
• Storage: If storing the battery for an extended period, ensure it is partially charged (not fully charged or fully discharged). Store it in a cool, dry place, away from direct sunlight and extreme temperatures.
• Disposal: When the battery reaches the end of its life, do not dispose of it in household waste. Ni-CD batteries contain cadmium, which is a hazardous substance. Recycle it at an authorized battery recycling facility.

6. Troubleshooting

If you encounter issues with your battery, consider the following common solutions:

• Battery Not Charging:
  • Ensure the battery is correctly seated in the charger.
  • Verify the charger is plugged in and receiving power.
  • Check for any visible damage to the battery or charger contacts.
  • Confirm the charger is compatible with Ni-CD batteries.
• Short Operating Time:
  • Ensure the battery was fully charged before use (especially the initial overnight charge).
  • The battery may be nearing the end of its lifespan and require replacement.
  • Operating the radio at high power or frequent transmissions will reduce battery life.
• Radio Not Powering On:
  • Check if the battery is properly installed and fully charged.
  • Inspect battery and radio contacts for dirt or corrosion.
  • Test with a known good battery if available.

If problems persist after attempting these solutions, contact customer support.
