Using your phone
Improving antenna performance
The antenna is integrated in your phone, under the lower part of the
back cover.
Avoid putting your fingers on this area when the phone is switched
ON.
If your fingers obstruct the antenna, the phone may have to operate
with a higher power level than usual, decreasing its efficiency
quickly. It could also affect the quality of your communications.
Increase the battery life of your phone
- Don't press the keys when not necessary: each keypress
activates the backlight, and uses much power.
- Don't obstruct the antenna with your fingers.
- Activation of the Bluetooth
®
function reduces the phone battery
life. We recommend you deactivate it when not in use.
