Charging time can vary according to the remaining battery charge and the charging environment.
The following are approximate charging times when charging is performed under the conditions described.
- When the transmitter's battery is completely depleted
- Operated using the AC adapter included with the KATANA-AIR/KATANA-AIR EX (PSB-12U)
NOTE:
-When charging via the TRANSMITTER IN jack on the KATANA-AIR unit, you must turn on the power to the KATANA-AIR.
-The transmitter that has not been used for a long time may be battery completely discharged (or near status). The transmitter in a discharged state does not charge through the TRANSMITTER IN jack.
| Charging via USB | Charging via the TRANSMITTER IN jack | |
|---|---|---|
| 40 deg. C/104 deg. F | After approximately 10 minutes, the indicator flashes red, and charging remains paused thereafter (because charging is inhibited at high temperatures). | After several minutes, the indicator flashes red, and charging remains paused thereafter (because charging is inhibited at high temperatures). |
| 35 deg. C/95 deg. F | After approximately 1 hour, the indicator flashes red (for several seconds), subsequently lighting up orange, and charging is fully completed in a total of approximately 2 hours. | After approximately 10 minutes, the indicator flashes red (for several seconds), subsequently lighting up orange, and low-speed charging is performed. At approximately 5 hours, charging is about 90% complete. |
| 30 deg. C/86 deg. F | The battery is fully charged in approximately 2 hours. | After approximately 30 minutes, the indicator flashes red (for several seconds), subsequently lighting up orange, and low-speed charging is performed. At approximately 5 hours, charging is about 95% complete. |
| 25 deg. C/77 deg. F | The battery is fully charged in approximately 2 hours. | At about 1 hour, the indicator momentarily lights up red or green, or flashes red for several minutes, and subsequently lights up orange and low-speed charging is performed. The battery is fully charged in approximately 4 hours. |
| 5 deg. C/41 deg. F | The battery is fully charged in approximately 2 hours. | The battery is fully charged in approximately 2 hours. |
