■ Connect a headset
You can connect a Nokia universal 
3.5 mm headset to your device. 
■ Wrist strap
Insert a thread through the wrist strap 
hole. Place the thread around the post. 
Tighten the thread.
■ Antenna
Your device may have internal and external antennas. 
Avoid touching the antenna area unnecessarily while 
the antenna is transmitting or receiving. Contact with 
antennas affects the communication quality and may 
cause the device to operate at a higher power level than 
otherwise needed and may reduce the battery life.
