Step 2

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 noise sources such as a window

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 unit or move the base unit 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

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

Away from another cordless telephone

Step 2: Setting up the base unit (continued)

Notes

• Use only the supplied AC-T46 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.

Tips

• If your telephone outlet is not modular, contact your telephone service company for assistance.

• To remove the wall bracket, press the upper tab.

Place the handset on the base unit.

You can place either side facing up.

The CHARGE lamp lights up when the handset is properly seated on the charge terminals of the base unit. Charge the battery pack for more than 12 hours so that the battery is fully charged. The CHARGE lamp remains lit even after charging is completed.

Getting Started

Step 3: Preparing the battery pack (continued)

Battery duration

A fully charged battery pack lasts for about:

• Approx. 6 hours when you use the handset continuously

• Approx. 10 days (RING ON mode) or 1 month (RING OFF mode) 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 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 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 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 Sony BP-T24 rechargeable battery pack.

Note

Battery life may vary depending on usage condition and ambient temperature.

Caller ID Features

Understanding the Caller ID service

Caller ID allows the caller’s phone number to be shown on the display before you answer the call. In order to use this feature, you must first subscribe to Caller ID service. The name of this service may vary depending on your telephone company.

To use this feature, be sure to enter your area code (see page 13).

When you receive a call

The phone number appears on the display with the date and time as shown in the following example.

If your Caller ID service includes the caller name service, the caller’s name also appears on the display (up to 15 letters).

Caller’s name

The date and time received*

When you answer the call, the Caller ID display changes to the “TALK” display.

* The date and time in the display are transmitted from the telephone company which

offers the Caller ID service, therefore may differ from the date and time you set on the base unit.

Notes

• If the RING switch is set to OFF:

- when the handset is off the base unit, the Caller ID is not displayed, and it is not kept in the Caller ID list (see page 40). If you set it back to RING ON while the phone is ringing, the Caller ID appears from that moment.

- when the handset is on the base unit, the Caller ID is displayed, and it is kept in the Caller ID list.

• The caller ’s phone number and/or name will not appear in the following cases:

- “OUT OF AREA”: when the call is made through a telephone company which does not offer Caller ID service (including international calls).

- “PRIVATE”: when the call is “blocked”. For privacy reasons, many states allow callers the option to prevent his or her telephone data from being displayed on the other party’s Caller ID display.

• If the call is from an office which uses multiple lines, the displayed phone number may not match the number you use to call the extension.

About the memory match function

If you receive a call from a phone number which is stored on one of the ONE-TOUCH DIAL buttons (see page 21) or in the Phone Directory (see page 23), the ringer sound will change to a higher tone from the second ring.

Note

The memory match function does not work with “OUT OF AREA” or “PRIVATE” calls; and it may not work with calls made from an office which uses multiple lines because the number does not always match the one you stored in this phone.

3-2. PROTOCOL

1. General

This system realizes the TX/RX superframe by TDD system. The relation of master/slave dose not decide identification regarding the protocol between BS and HS, but the initiated side is the master and the requested side is the slave when the RF link has been established.

2. Initial acquisition

In order to establish the RF link between BS and HS, both of BS and HS need to have the same system ID. When “power” is applied to this system, the system have to do Initial Acquisition in order to have the same system ID. It is to exchange a parameter when the HS is parked on the BS, as soon as the system do System Parameters Re-initialization.

3. System parameter re-initialization

This System Parameters Re-initialization can realize that the HS is parked on the BS. So after the BS recognized to be parked the HS, the BS calculates a system parameter, and then it outputs this data from the ARTO port, and then the system establishes the RF link. In order to establish this link, the HS send the A-Frame to the BS after the HS received the system parameter, and then the BS send the A-Frame to the HS. The process of System Parameters Re-initialization is as follows.

(2) BS

The BS is supplied the power by AC line. While the BS is the stand-by, the BS is always a wake state. While the BS monitors the current channel, the BS monitors also the other channel at the same time Because if the current channel can not use by some interference, the system needs the clear channel information as a part of system parameter for a channel hop. If the BS can not receive the A-Frame of Heart-beat from the HS, it become “link error”, and the system become error recovery mode.

5. Link Establishment

According to the following Fig. 3-1, the requested side for link establishment is the master. The system have to exchange the A-Frame for link establishment, and each system ID should be the same ID, and then the system link is established. The protocol and timing chart of link establishment are as follows.

9 Continuous TX (CH10, Low power) 10 Continuous TX (CH20, High power) 11 Continuous TX (CH20, Mid power) 12 Continuous TX (CH20, Low power) 13 TDD mode (Master timing, CH1, High power) 14 TDD mode (Master timing, CH1, Mid power) 15 TDD mode (Master timing, CH1, Low power) 16 Return to Test Mode Idle B-2.

Note: When the button pressing count is 1-15, the Audio block is in the

line speech status.

[Charge Detection, ARTO Terminal Output Test/ EEPROM Clear]

1. Upon detection of Charge signal in the Test Mode Idle B-1 status, 2.4 kHz square wave is output from the IC751 pin ef (ARTO terminal).

2. At this time, the contents of EEPROM are all c leared.

Automatic Answering System Test Mode

4-3. BASE UNIT TEST MODE

[Start-up]

1. Keeping [MEMO], [MAIL BOX2] pressed simultaneously, or

[HANDSET LOCATOR], [MEMO], [MAIL BOX2] pressed si-

multaneously, turn the power on and the Test mode will start.

2. Immediately after the Test mode started, a beep tone sounds for 500 msec and the LCD lights up fully, then the unit goes in the Test Mode Idle status.

3. When the T est mode started by pressing [HANDSET LOCATOR],

[MEMO], [MAIL BOX2] simultaneously, “HIGH” is output from

the IC201 pin tg (P AGE ON terminal). (To start the Test mode on the IC751 side)

4. If the first status is not returned from the DSP when the Test mode started, the unit goes in the Test Mode Idle status without performing DSP initial setting and memory data check. (The Test mode can be started even if DSP board is not attached.)

5. During operation in the Test mode, the [HANDSET LOCATOR] key input is always monitored, and “HIGH” is output from the IC201 pin tg (P AGE ON terminal) while

[HANDSET LOCATOR] key is pressed. However, at the key input test, “HIGH” is not output from the IC201 pin tg (PAGE ON terminal).

[Operation in Test Mode Idle]

1. In the Test Mode Idle status, LCD is all ON and the ANSWER ON/OFF LED and the IN USE LED are OFF.

2. In the Test Mode Idle status, MIC is OFF, SPEAKER is OFF, TX-MUTE and RX-MUTE are in MUTE, charging is in normal status, line is open, and volume is set to initial value.

3. In the Test Mode Idle status, the key input is always monitored, and in the even of key input, a k ey touch tone is sounds, then the unit goes in each status selected.

[Key Input and LED Test]

1. Press the [GREETING] key in the Test Mode Idle status, and the Key Input and LED Test mode will start.

2. Press the following keys successively in the given order.

[VOLUME-] → [VOLUME+] → [GREETING] → [SET/REC]

→ [TIME] → [ERASE] → [MAIL BOX3] →

[ANSWER ON/OFF]

→ [MAIL BOX2] → [QUICK/SKIP] → [MEMO] → [MAIL BOX1] → [HANDSET LOCATOR] (IN USE LED ON)

(ANSWER LED ON) →

[SLOW REPEAT]

If key input sequence is correct: A completion tone sounds and the T est Mode Idle status resumes. If key input sequence is wrong: An error tone sounds and the Test Mode Idle status resumes.

Note: A key touch tone sounds when each key is pressed.

[Line Close and Ring Detection Test]

1. Press the [SET/REC] key in the T est Mode Idle sta tus, and the Line Close and Ring Detection Test mode will start.

2. During the line close and ring detection test, IC201 pin wj (RING DET terminal) is monitored, and if IC201 pin wj is on “LOW” level, the ANSWER ON/OFF LED turns on, or if “HIGH” level, it turns off.

3. During the line close and ring detection test, the line close detection port is monitored, and if it is on “HIGH” level, the IN USE LED turns on, or if “LOW” level, it turns off.

4. Press the [ERASE] ke y to return to the Test Mode Idle status.
