Charging

Unable to charge the battery.
When the battery pack is fully charged, the lamp does not light up.
Be sure to charge using the supplied AC adapter. Malfunction in the unit that occurred due to the use of an AC adapter other than the one provided is not included in the warranty.
Check the connection, then disconnect and reconnect the charging adapter cable.
Charging cannot be performed under low or high temperature environments.
Charge under the room temperature range of 10°C to 35°C. (Under environments beyond the temperature range, charging may stop to protect the battery pack.)
Using a non-original AC adapter may result in damage to this unit. Be sure to use an original AC adapter.

The remaining battery display is not correct.
If this unit is used for long periods of time in high or low temperatures, or if the battery pack is repeatedly charged, the amount of remaining battery may not be displayed correctly.

The battery runs out quickly even after charging.
Be sure to charge using the supplied AC adapter. Malfunction in the unit that occurred due to the use of an AC adapter other than the one provided is not included in the warranty.
The performance of the battery will drop temporarily when the temperature is -10°C to 0°C, this will cause the remaining recording time to shorten.
When the recording time becomes extremely short even when the battery is fully charged, the battery needs to be replaced. For details on replacing the built-in battery (subject to a fee), consult the nearest JVC service center.

Troubleshooting

Turn off this unit, wait for a while, and turn it on again. (This unit stops automatically to protect the circuit when the temperature rises.)

The continuous shooting speed of still images is slow.
The continuous shooting speed will drop if this function is used repeatedly. Continuous shooting speed may drop depending on the SD card or under certain recording conditions.

"VIDEO QUALITY" ( p. 79)

The inside of the lens is foggy.
Open the terminal cover; close the LCD monitor and leave as is for a while to reduce the temperature.

Preventing fogging inside the lens
• Models with waterproof function are airtight. When the temperature rises during recording, condensation can occur inside the lens due to the internal humidity.
During recording
To prevent the temperature of this unit from rising, we recommend that you use the unit in the following ways.
1 Avoid frequent exposure to direct sunlight.
Record under the shade or use an umbrella. Best if you could keep a wet towel cover the unit.
2 The use of a tripod is recommended.
Long hours of recording while holding the unit in your hands will cause the temperature of the unit to rise.
3 It is better to leave the terminal cover open while recording.
However, the waterproof, dust-proof and shockproof features do not function in this condition. Do take note of the environment when using the camera. (Do not use a wet towel.)
4 Make sure to turn off the power when you are not recording.
When the LCD monitor is closed, the unit turns off.

During charging
It is recommended to charge the unit in a low humidity environment.
The moist air inside the unit can cause condensation.
We recommend that you charge the unit in a room where humidifier is not in use, and in an air-conditioned room during summer.
