Do not heat the battery device, expose it to very low temperatures, or expose it to any
liquid.
Dispose of the used appliance at a specialist disposal point. The battery is subject to
normal wear during use. Battery life when fully charged is reduced over time. This is normal
for all these types of devices.
Battery life depends on how the device is used; primarily from factors such as voice
power, operating modes and functions used, ambient temperature, continuity of use or
intermittent use. The battery also discharges when the device is not in use.
If you do not use the device for an extended period of time, charge the battery regularly.
Completely discharging the battery and leaving it in a discharged state for an extended
period of time shortens the battery life and may damage the battery.
Always charge the battery up to full charge. Incomplete charging shortens battery life.
Do not overload the battery. The charging must be completed immediately after the
charging time specified in the device manual has elapsed. Some devices have the function
of automatically turning off charging when fully charged.
Neither the seller nor the manufacturer shall be liable for any damages resulting from
improper handling of the battery.
Due to its natural wear, the battery is covered by a shortened 6-month warranty of the
manufacturer. In case of premature battery wear due to improper or very heavy use, the
battery must be replaced by a specialist service.
RECOMMENDATIONS FOR THE USE OF HIGH-POWER AUDIO DEVICES:
- always turn the voice force regulator to the extreme left position - the minimum level of
voice force before turning on the power supply. Too much power at the time of switching on
can cause damage to the speaker, hearing damage and other unwanted effects of very loud
sound.
- in the event of sound disturbances, the source signal level and the amplification level shall
be reduced.
- Before listening at a high volume level, make sure that very high volume sound does not
cause damage or inconvenience to people nearby.
- the device must not be within range of young children.
- Children must not be exposed to high-intensity sound.
