NOTES ON BATTERY USE
The average battery life after a complete charge cycle is approximately 8 hours, a value
that can decrease to almost half according on system audio level.
This duration also depends on other factors such as:
- usage environment temperature (generally the battery discharges more
quickly at low temperatures)
- progressive state of wear due to the charge / discharge cycles
- possible improper use
The average time required for full recharge - depending on several factors - is about
6 hours.

SAFETY PRECAUTIONS AND INSTRUCTIONS FOR CORRECT
DISPOSAL OF VRLA (LEAD-ACID VALVE REGULATED) BATTERIES
CAUTION:
Under normal conditions of use and operation of the device, there are no
hazards or risks for the lead-acid battery. However it is recommended to take note
of the following characteristics and adopt following safety precautions.
• VRLA batteries include an electrolyte containing diluted sulfuric acid. Sulfuric acid
has corrosive effect and can cause severe chemical burn
• The lead compounds are classified as toxic (if ingested)
• In case of spillage use a binder, such as sand, to absorb spilled acid; use quicklime/
sodium carbonate to neutralize; dispose applying local regulations; do not allow entry
into sewers, ground or waterways.
• During the charge phase, or during operation, the lead-acid batteries may develop
hydrogen and oxygen gas, which in certain circumstances may form an explosive
mixture.
• The lead-acid may contain a considerable amount of energy, which can be a high current
source as well as a source of serious electrical shock in the event of a short circuit.
• In case of fire don’t use water, but only fire extinguishing media like CO2 or dry powder
extinguishing agent.
• To replace always refer to a qualified center.
• Keep indoors and away from heat - lead-acid batteries are not subject to freezing up
to a temperature of -50°C (-58°F).
• Whenever possible, charge the battery completely. Never store it completely empty or
half empty. If the device is inactive for a long period, disconnect the battery, covers the
terminals and store the battery in a dry place away from heat sources, and regularly
recharge the battery.
CAUTION
: This device contains a valve-regulated lead-acid VRLA battery, used
batteries are considered toxic waste and must be disposed in compliance with local
regulations.
