USING THIS GUIDE
Your dual band/dual mode T300 phone operates on PCS 800 MHz
digital/analog and 1900 MHz digital networks. Digital systems provide
improved voice quality as well as security and privacy. Dual mode means
that if you travel to an area without digital service, your phone will
transfer to an analog system with no gap in your connection.
Certain features included in this guide called Network services are
supplied by wireless service providers. Before you can activate or use any
of these Network services, you must subscribe to the services from your
home service provider. For a full list and explanation of Network
services, please ask your service provider.
One of the most versatile features of the T300 phone are the softkey
functions. They provide immediate access to the actions you are most
likely to do next, depending on what you are currently doing. If you are
dialing a phone number, the Options softkey brings you directly to
options such as storing the number or placing a 1 before the number for
long distance dialing without fumbling through menus. Softkey actions
and labels change with each new screen.

BATTERY SAFETY TIPS
• Replace the battery when it will not hold a charge, or when operating time
decreases dramatically.
• Use only the Mitsubishi chargers specified for this battery. Using other charg-
ers or batteries may cause damage to the battery by overcharging or exces-
sively high current flow.
• It is normal for batteries to become warm during charging.
• Do not leave NiMH batteries connected to a charger longer than necessary;
overcharging will shorten battery life.
• Disconnect battery chargers from the power source when not in use.
• Do not leave the phone in a closed car during hot summer or cold winter con-
ditions or exposed to intense sunlight. The phone may temporarily not work
with a hot or cold battery.
• The recharging temperature range is 32°--104° F (0°--40° C). If you attempt to
recharge when the battery is above or below this range, acid leakage or over-
heating may result.
• Do not use or leave the battery near a heat source such as a stove, oven,
heater or fire (170° F = 76° C or higher).
• The battery is not waterproof. Do not immerse it in liquid or allow it to get
wet.
• Avoid contact of the battery terminals with metal objects (such as keys, paper
clips, coins, chains) or excessive static electricity which may short circuit the
battery.
• If the battery terminals become soiled, clean them with a soft cloth.
• Do not try to disassemble or modify the battery as injury or burns may result.
• Do not drop or subject the batteries to strong physical shocks.
• Keep batteries out of the reach of children.
• Batteries may explode if discarded into a fire or heated.
