Speakerphone Use
Place the MTP850 30 to 60 centimetres away from you. In a
noisy environment, you may want to move the MTP850
closer to you for better transmission.
Looking after your MTP850
Never leave your MTP850 or battery in extreme
temperatures (over 60 °C) — for example, behind
windscreen in very hot, direct sunlight. Do not immerse your
MTP850 in water.
To clean your MTP850, use a moistened or antistatic cloth.
DO NOT use a dry or electrostatically charged cloth.
