Proper use of the battery
Battery in this device can be charged with a charger. If the level of energy in the battery is low, recharge it. To prolong battery life, let it discharge beneath 20% of the
battery capacity before connecting the phone charger and charge it up to 100%. If not used, unplug the charger from the phone. Excessive charging causes shortened
battery life. The battery temperature affects the quality of charging. Before the charging process starts, lower or raise the temperature so that it is close to room
temperature (approx. 20°C/68°F). If the battery temperature exceeds 40 C/104°F the battery must not be charged! If the battery overheats, the device will display an
º
appropriate message. 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. Use the battery only according to its intended purpose. Avoid leaving the battery within a magnetic field range, because it
shortens its lifespan. Do not use a damaged battery Do not throw the battery into flames! Do not throw away 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. 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 only original accessories because violation of this rule may result in invalidation of the warranty.
Exposing the phone to extreme temperatures can reduce the level of protection. It is recommended that the phone is not used at temperatures below 0°C/32°F or higher
than 40°C/104°F.
Specific absorption rate (SAR)
SAR is a value indicating the amount of radiation emitted by the phone. The SAR limit recommended by the Council of the European Union is 2 W/kg. The maximum
SAR value for a HAMMER phone is 1.395 W/kg.
The maximum radio frequency power emitted in the
frequency range.
