Proper use of the battery
Battery in this device can be charged with a charger. If the battery level is low, recharge
it. To prolong battery life, let it discharge beneath 20% of the battery capacity before
connecting the charger. Then charge it back to 100%. If not used, unplug the charger
from the phone. Excessive charging might cause shortened battery life. The
temperature of the battery has an impact on its charging cycle. Prior to the charging
process, cool the battery or raise its temperature so that it is similar to the room
temperature (approx. 20°C). If the battery temperature exceeds 40
°
C the battery must
not be charged! If the battery overheats, the device will display an appropriate
message. Use the battery only according to its intended purpose. Avoid leaving the
battery within a magnetic field range, because it shortens its life. Do not use a
damaged battery. The battery lifespan can be shortened, if it has been exposed to
very low or very high temperatures - this causes interference to the phone, even when
the battery has been properly charged. Do not throw the battery into flames! Do not
throw a worn-out battery – send it or return it to an authorized recycling point.
Proper phone maintenance
To extend the life of your phone, follow the guidelines. Keep the phone and its
accessories out of reach of children. Store the phone in a dry place free of moisture.
Avoid using the phone in high and low temperatures; it can shorten the life of phone
electronic components, melt the plastic parts and destroy the battery. Do not try to
disassemble the phone. Tampering with its structure in an unprofessional manner may
cause serious damage to the phone or destroy it completely. For cleaning use only a
dry cloth. Never use any agent with a high concentration of acids or alkalis. Use the
original accessories only. Violation of this rule may result in cancellation of the
warranty. It is recommended that the phone is not used at temperatures below 40°C
/ 104°F or higher than 0°C / 32°F.
