The battery life of the linear PCM recorder is short.

  • The battery life values listed in this Help Guide are measured values acquired under our measurement conditions and may shorten depending on the usage of your linear PCM recorder.

  • Your linear PCM recorder still consumes slight battery power while no operations are in progress. If you do not intend to use the linear PCM recorder for an extended period of time, it is recommended that you turn the power off. It is also recommended that you set [Auto Power Off] to a shorter period of time. This will help you save battery power in case you forget to turn off the power of the linear PCM recorder.

  • If you use REC Remote or play audio with a Bluetooth audio device, the battery life shortens. When you do not intend to the Bluetooth function, set [Bluetooth ON/OFF] to [OFF].

  • When you start charging the built-in rechargeable battery of your linear PCM recorder, the battery indicator appears quickly on the display window. However, this does not indicate that the battery is fully charged. When the battery is running out of power, it takes about 3 hours to fully charge the battery.

  • When you have not used your linear PCM recorder for an extended period of time, repeat charging and discharging (by operating the linear PCM recorder) for several times.

  • You are using your linear PCM recorder under the temperature of 5 °C (41 ºF) or below where the battery wears quickly. This is due to the characteristics of the battery and does not indicate a malfunction.

  • The built-in rechargeable battery is deteriorated.

    The rechargeable battery is capable of charging about 500 times but the rechargeable times vary depending on the usage of your linear PCM recorder. If the fully charged battery wears out in half the time it normally does, it indicates that the battery is deteriorated. Consult your nearest Sony dealer.
