RECOMMENDATION:
• To maximise battery life, disconnect external power immediately after
charging is complete. Even though the device draws minimal power,
unplug the adapter once charging is nished. If you do not intend to use
the device for an extended period, charge the battery to at least half
its capacity. Estimate this according to the usual charging time. Avoid
storing the device with a fully discharged battery. If the battery is nearly
depleted (as indicated by low battery warnings or auto shuto). Have
a battery that has lost most of its capacity (the battery is consumed)
professionally replaced at a service centre.
EN - 6
EN - 7
CAUTION:
Before connecting to any power source, make sure that:
• All other connections have been completed.
• The socket is within reach during installation.
• The appliance and its adapter must be connected to
a 100 240 V 50/60 Hz AC power source using a two-pin plug.
Using USB and SD Cards:
• The USB/SD memory device needs to be connected directly to the
device. Do not use force.
• Do not use a USB extension cable to avoid data transmission failure and
interference. Electrostatic discharges may aect device operation. If this
occurs, restart the device.
• The device can play similar le types and formats from USB/SD
devices as it can from discs. Before using a memory device, test its
communication function with the device and the speed of data reading.
Please keep in mind that reading data through an external connector
may be slower and that les with high data ow rates may not be played
back smoothly. To achieve maximum reading speed, we recommend
keeping the disk space defragmented. Use the FAT32 le system, one
partition, without protection.
• If the memory device reading is not smooth, undesirable phenomena
may occur, such as dropout of parts of the image (pixelation) or entire
frames, sound faults, in extreme cases up to stopping the reading
operation. Unexpected device behaviour or the presence of viruses or
malware may also disrupt operation and require a restart.
• The USB connector is a standard type and cannot power USB devices
with high power consumption (e.g. HDD hard drives). Use devices with
their own power supply and power them from their own power sources.
• The device was designed with regard to maximum compatibility
with memory devices. Given the variety of devices on the market,
compatibility with every USB/SD device cannot be guaranteed. In case of
problems, try formatting the memory device. If the problem persists, try
using a dierent memory device.
