4. Operating Instructions

After installation, place your telephone handset on its charging base for an initial charge. For Ni-MH batteries, it is recommended to fully charge the battery before its first use to optimize battery life.

• Initial Charge: Allow the battery to charge for at least 12-16 hours before the first use, even if the phone indicates a full charge sooner.
• Normal Use: For daily use, return the handset to the charging base when not in use. This helps maintain the battery's charge.
• Discharge Cycles: To prolong the overall lifespan of Ni-MH batteries, it is beneficial to allow the battery to fully discharge occasionally (e.g., once every few months) before recharging it completely.

5. Maintenance and Storage

• Cleaning: Keep the battery contacts and the telephone's charging contacts clean using a dry, soft cloth.
• Storage: If the battery will not be used for an extended period, store it in a cool, dry place at room temperature. For long-term storage, it is best to store Ni-MH batteries with a partial charge (around 40-50%) rather than fully charged or fully discharged.
• Avoid Extreme Temperatures: Do not expose the battery to extreme heat or cold, as this can degrade performance and shorten its lifespan.

6. Troubleshooting

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

• Battery Not Charging:
  • Ensure the handset is correctly seated on the charging base.
  • Check that the charging base is properly connected to a power source.
  • Clean the charging contacts on both the handset and the base.
  • Verify the battery is correctly installed and its connector is secure.
• Short Talk Time/Standby Time:
  • The battery may not be fully charged. Ensure it has undergone a full initial charge or a complete recharge cycle.
  • Ni-MH batteries can develop a 'memory effect' if not fully discharged occasionally. Try a full discharge/recharge cycle.
  • Battery lifespan naturally decreases over time. If the battery is old, it may need replacement.
• Phone Not Powering On:
  • Ensure the battery is correctly installed and charged.
  • If the issue persists, the phone itself may have a fault, or the battery may be defective.
