Speakerphone quality and display legibility
• To ensure good speakerphone quality (OpenStage 20/20 G only), the
area in front of the microphone (front right) should be kept clear. The
optimum speakerphone distance is 50 cm.
• Proceed as follows to optimize display legibility:
– Turn the phone to tilt the display. This ensures you have a frontal view
of the display while eliminating light reflexes.
– Adjust the contrast as required Æ page 96.
