Setting up the base unit
Do the following steps:
• Choose the best location
• Connect the base unit
• Choose the dialing mode
Choose the best location
Where you place the base unit affects the reception quality of the handset.
Away from television sets and other electronic equipment
Near a central location and on a level surface
CAUTION: Should you experience intermittent loss of audio during a conversation, try
moving closer to the base or move base unit away from other noise sources.
The cordless telephone operates at a frequency that may cause interference to nearby TVs and VCRs; the base unit should not be placed near or on the top of a TV or VCR; and, if interference is experienced, moving the cordless telephone farther away from the TV or VCR will often reduce or eliminate the

interference.
Getting Started
Away from noise sources such as a window by a street with heavy traffic
Away from heat sources, such as radiators, airducts, and sunlight
Away from a microwave oven Away from excessive moisture, extremely low temperatures, dust, mechanical vibration, or shock
Away from a personal computer

Step 2: Setting up the base unit (continued)
Notes
• Use only the supplied AC-T130 AC power adaptor. Do not use any other AC power adaptor.
• Connect the AC power adaptor to a continuous power supply.
• Place the base unit close to the AC outlet so that you can unplug the AC power adaptor easily.
Tip
If your telephone outlet is not modular, contact your telephone service company for assistance.

Step 3: Preparing the battery pack (continued)
Basics
Making calls
Battery duration
A fully charged battery pack lasts for about:
• Approx. 7 hours when you use the handset continuously
• Approx. 6 days when the handset is in standby mode.
Notes
• The battery pack will gradually discharge over a long period of time, even if not in use.
• If you leave the battery pack in the handset without charging it, the battery pack will be completely discharged. It may require several times of charging to recover its full capacity.
To obtain the best performance from the battery
Do not place the handset on the base unit after each call. The battery works best if the handset is returned to the base unit after two or three calls. However, do not leave the handset off the base unit 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 10 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-T23 rechargeable battery pack.
Note
Battery life may vary depending on usage condition and ambient temperature.

Picking up new messages
1
Call your telephone number from a touch-tone phone.
2
When you hear the greeting, press (#) and enter your remote ID code (security code). You will hear a confirmation beep. The number of new messages will be announced.
3
Press the keys in the “Table of control codes” below for the desired operation command.
4

TEST MODE

BASE UNIT
1. Entering the Test Mode
1. While pressing the [HANDSET LOCATOR] key, turn the power ON, then change over the “PULSE” to “TONE” within 4 seconds.
2. When enter the test mode, Light up the
[DIAL MODE] switch from
[CHARGE] and
[IN USE] LEDs.
2. Change the Mode
Press and hold the [HANDSET LOCATOR] key for about 2 sec­onds to change the mode like Mode 1, Mode 2, Mode 3, Mode 4,
Mode 1....
Mode 1:
[CHARGE] LED : Lights up.
Function : Change the channel. Operation : Each time the [HANDSET LOCATOR] key
is pressed momentarily, change the channel like 0, 1, 2...9, 0... (default channel is 5ch)
Mode 2:
[CHARGE] LED : Goes off.
Function : Toggle TX power. Operation : Each time the [HANDSET LOCATOR] key
is pressed momentarily, change over ON/ OFF. (default status is ON)
Mode 3:
[CHARGE] LED : Lights up.
Function : Not used in servicing.
HANDSET
1. Entering the Test Mode
1. Press two keys of [3] and [#] simultaneously.
2. When enter the test mode, the happy tone is emitted.
2. Key Functions
[CHANNEL] key
