Troubleshooting and error codes

Troubleshooting Built-in Battery
If you encounter problems with this unit, check the following before requesting service: This unit is equipped with a built-in lithium-ion battery. Before using this Unit, be sure to read the following cautions:
1. Refer to the “Troubleshooting” section in the "Detailed User Guide". http://manual3.jvckenwood.com/index.html/ • To avoid hazards
  • do not burn.
  • do not modify or disassemble.
  • do not expose this Unit to temperatures exceeding 60 °C, as this may cause the built-in battery to overheat, explode or catch fire.
2. This unit is a microcomputer-controlled device. Electrostatic discharge, external noise and interference (from a TV, a radio, etc.) might prevent it from functioning properly. In such a case, reset the unit. • To prevent damage and prolong service life
  • do not subject to unnecessary shock.
  • charge within the temperature range of 10°C to 35°C. Cooler temperatures require longer charging time, or in some cases stop charging at all. Warmer temperatures prevent complete charging, or in some cases stop charging at all.
  • store in a cool, dry place. Extended exposure to high temperatures will increase natural discharge and shorten service life.
  • keep a 30% battery level (%i%) if the battery is not to be used for a long period of time.
  • In addition, fully charge and then fully discharge the battery every 6 months, then continue to store it at a 30% battery level (%i%).
  • remove the AC adapter from the unit when not in use, as some machines use current even when switched off.
  • do not drop intentionally or subject to strong impact.
① Remove all the cables from this unit.
② Press the "Reset button" located inside of the terminal cover. (Before pressing the reset button, close the LCD monitor to turn off this unit.)
③ Reattach the AC adapter, open the LCD monitor and this unit powers on automatically.
3. If the above do not solve the problem, consult your nearest JVC dealer or JVC service center.
