YAESU SBH-28 Desktop Rapid Charger Instruction Manual

1. Introduction

The YAESU SBH-28 is a desktop rapid charger designed for use with the YAESU FT-70DR handheld transceiver and its compatible battery packs. This charger provides a convenient and efficient method for recharging your radio's battery, ensuring your device is always ready for operation. It requires an external AC adapter (such as SAD-18B, SAD-24B, or SAD-25B, typically supplied with the radio) or a 12V DC adapter (SDD-13) for power.

2. Safety Information

• Use only the specified YAESU AC adapters (SAD-18B, SAD-24B, SAD-25B) or the SDD-13 12V DC adapter. Using an incorrect power adapter may damage the charger or the radio and could pose a fire hazard.
• Do not expose the charger to water or moisture.
• Do not attempt to disassemble or modify the charger. Refer all servicing to qualified personnel.
• Ensure the charger is placed on a stable, flat surface away from direct sunlight and heat sources.
• Keep out of reach of children.

5. Operating Instructions

To charge your FT-70DR radio or its battery pack:

1. Ensure the SBH-28 charger is properly connected to a power source as described in the Setup section.
2. Carefully place the FT-70DR radio (with its battery attached) or a standalone battery pack into the charging cradle. Ensure the contacts on the battery/radio align with the charging terminals in the SBH-28. The radio or battery should sit securely in the cradle.
3. Refer to your FT-70DR radio's instruction manual for details on the charging indicator light behavior (e.g., color changes, blinking patterns) to confirm charging status. The SBH-28 facilitates rapid charging.
4. Once the battery is fully charged, remove the radio or battery pack from the cradle.

6. Maintenance

• Keep the charging contacts clean and free of dust or debris. Use a dry, soft cloth to wipe them if necessary.
• Do not use harsh chemicals or abrasive cleaners on the charger.
• Store the charger in a dry environment when not in use.

7. Troubleshooting

• Charger not powering on or radio not charging:
  • Verify that the power adapter is securely connected to both the SBH-28 and the wall outlet/DC source.
  • Ensure you are using a compatible YAESU power adapter (SAD-18B, SAD-24B, SAD-25B, or SDD-13). Incorrect adapters may not provide sufficient power or may have incorrect voltage/polarity.
  • Check the power outlet or DC source for functionality.
  • Ensure the radio or battery pack is correctly seated in the cradle, making proper contact with the charging terminals.
• Charging indicator light flickers or shows inconsistent status:
  • This can sometimes occur if the radio or battery is not perfectly seated. Try re-seating the radio/battery in the cradle.
  • Ensure the power adapter connection is firm.
  • Consult your FT-70DR radio's manual for specific interpretations of indicator light behavior.
