Operating Environment
• Do not use or charge your mobile phone in dusty, damp
or dirty places, or areas with magnetic fields. Otherwise,
the circuit may not function properly.
• Your mobile phone complies with RF specifications when
used near your ear or at a distance of 1.5 cm from your
body. Keep your mobile phone 1.5 cm away from your
body to meet the aforementioned requirement. Ensure
that accessories such as your mobile phone case or holster
are not composed of metal components.
• Avoid using your mobile phone when charging in the
middle of a storm to prevent possible dangers caused by
lightning.
• Avoid touching the antenna while on a call. Touching the
antenna affects call quality and increases power
consumption. In effect, talk time and standby time are
reduced considerably.
• Observe the local laws and regulations while using your
mobile phone. Respect others' privacy and legal rights.
• Use accessories authorized by Starmobile. Using
unauthorized accessories with your mobile phone will
render the warranty null and void.
• Keep the ambient temperature between 0°C and 40°C
during mobile phone.
Preventing Hearing Damage
Using the receiver, earbuds, headphones, speakerphone or
earpieces at high volume can result in permanent hearing
loss. Be extremely careful when listening at high decibel
levels. Set the volume to a safe level. If you experience
strange ringing sounds in your ears or if you hear muffled
speech, get your hearing checked immediately. If you
continue to use high volume, your hearing will soon get
affected.
