Getting Started About the station number When you start charging the battery, "HANDSET 1" appears on the display of the cordless handset. This shows the ID number for each cordless handset and base phone of the system, called "station number." The station number of the base phone is set to 0 and that of the cordless handset (supplied with the base phone) is set to 1 at the factory. The station number of the cordless handset newly added to the system will be one of the number 2 through 4 in the order of registration. (See "Registering additional cordless handsets" on page 25.) HANDSET 1 NEW OLD MASSAGE RING OFF Battery duration A fully charged battery pack lasts for about: • Approx. 5 hours when you use the cordless handset continuously • Approx. 6 days when the cordless handset is in standby mode. Notes • The battery pack will gradually discharge over a long period of time, even when not in use. • If you leave the battery pack in the cordless handset without charging it, the battery pack will be completely discharged. It may require several times of charging to recover to its full capacity. • While charging, the battery pack warms up. This is not a malfunction. To obtain the best performance from the battery Do not place the cordless handset on the charger after each call. The battery works best if the cordless handset is returned to the charger after two or three calls. However, do not leave the cordless handset off the charger for a long period of time as this will completely discharge the battery pack. When to purchase a new battery pack If the battery lasts only a few minutes even after 12 hours of charging, the usable life of the battery has expired and needs replacement. Contact your local Sony authorized dealer or service center, and ask for a Sony BP-T38 rechargeable battery pack. Note Battery life may vary depending on usage condition and ambient temperature.
