3. Safety Information
Observe the following safety precautions to prevent damage to the battery, phone, or personal injury:

- Locate Battery Compartment: Turn your cordless phone handset over and locate the battery compartment cover.
- Remove Old Battery (if applicable): If replacing an old battery, carefully remove the compartment cover and disconnect the old battery's connector from the phone's socket.
- Connect New Battery: Align the connector of the Empire BF490210 battery with the socket inside the phone's battery compartment. Ensure the connector is inserted firmly and correctly. Do not force it.

5. Operating (Charging)
For optimal performance, follow these charging guidelines:
- Initial Charge: After installing the new battery, place the phone handset on its charging base for a continuous 12-16 hours. This initial charge is crucial for conditioning the NiMH battery and achieving its full capacity.
- Regular Charging: For daily use, return the handset to the charging base when not in use. This ensures the battery remains charged and ready.
- Charging Indicator: Refer to your phone's user manual for specific charging indicators (e.g., LED lights, screen icons).
- Use Original Charger: Always use the charging base and AC adapter that came with your cordless phone.
6. Maintenance
Proper maintenance can extend the life of your battery:
- Avoid Deep Discharge: While NiMH batteries are less prone to memory effect than NiCd, it's best to avoid completely draining the battery regularly.
- Clean Contacts: Periodically clean the metal contacts on both the battery and the phone's charging base with a dry, soft cloth to ensure good connection.
- Storage: If storing the battery for an extended period, charge it to about 50% capacity and store it in a cool, dry place. Recharge every 3-6 months to prevent over-discharge.
7. Troubleshooting
If you encounter issues with your battery, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Phone not powering on after battery installation. | Battery not properly connected or discharged. | Ensure battery connector is firmly seated. Place phone on charging base for initial charge. |
| Short talk time or battery not holding charge. | Insufficient initial charge, battery not fully conditioned, or aging battery. | Perform a full 12-16 hour initial charge. If issue persists, the battery may need to be cycled (fully discharge then fully charge a few times). |
| Phone not charging when on base. | Dirty contacts on battery or charging base, faulty charger. | Clean battery and charging base contacts with a dry cloth. Ensure the charging base is powered. Test with another known-good battery or charger if possible. |
