instructions.

Do not touch the antenna unnecessarily. 

 

Normal use position 

When placing or receiving a phone call, hold your phone to your ear, with the bottom towards 

your mouth or as you would a fixed line phone. 

 

Air Bags 

Do not place a phone in the area over an air bag or in the air bag deployment area. Store the phone safely before 
driving your vehicle. 

 

Seizures/Blackouts 

This phone is capable of producing bright flashing lights. 

 

Repetitive Strain Injury (RSI) 

To minimize the risk of RSI, when Texting or playing games with your phone: 

 

Do not grip the phone too tightly. 

 

Press the buttons lightly. 

 

Make use of the special features in the handset which minimize the number of buttons which have to be 

pressed, such as message templates and predictive text. 

 

Take lots of breaks to stretch and relax. 

 

Emergency Calls 

This phone, like any wireless phone, operates using radio signals, which cannot guarantee connection in all conditions. 

Therefore, you must never rely solely on any wireless phone for emergency communications. 

 

Loud Noise 

This phone is capable of producing loud noises which may damage your hearing. 

 

MP3 and video player function 

When listening to pre-recorded music or watching videos on your device, with headphones or earphones at high 
volumes, you run the risk of permanent damage to your hearing. Even if you are used to listening to music at a high 
volume and it seems acceptable to you, you still risk damaging your hearing. Reduce the sound volume to a 

reasonable level and avoid using headphones for an excessive period of time to avoid hearing damage. Different 
headphones, earphones or ear buds may deliver a higher or lower volume, at the same volume setting on your device. 

Always start at a low volume setting. Do not listen to music or video with headphones while driving.

This phone is capable of producing flash of light or use as a torch, do not use it too close to the eyes.

Your phone may become warm during charging and during normal use. 

 

Accessories 

Use only approved accessories. Do not connect with incompatible products or accessories. Take care not to touch or 
allow metal objects, such as coins or key rings, to contact or short-circuit the battery terminals. 

 

Connection to a Car 

Seek professional advice when connecting a phone interface to the vehicle electrical system. 

 

Faulty and Damaged Products 

Do not attempt to disassemble the phone or its accessory. Only qualified personnel must service or repair the phone 
or its accessory. If your phone or its accessory has been submerged in water, punctured, or subjected to a severe fall, 

do not use it until you have taken it to be checked at an authorized service centre. 

 

Battery Handling & Safety 

Always switch the device off and disconnect the charger before removing the battery. Only use the battery and 
charger supplied, or manufacturer approved replacements intended for use with your phone. Using other batteries 

and chargers could be dangerous. Do not disassemble or short-circuit the battery. Accidental short-circuiting can occur 
if a metallic object such as a key, paper clip, or pen touches the terminals of the battery. Improper battery use may 

result in a fire, explosion, or other hazard. If you believe the battery has been damaged, do not use it, take it to a 
service centre for testing.
