Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

NOTE FOR REPLACEMENT OF THE CRYSTAL VIBRATOR ON THE HAND MAIN BOARD

There are two types of crystal vibrators used on the HAND MAIN board. Accordingly, when replacing the crystal vibrator, replace the following reference number parts together. Similarly, when the following reference number parts are replaced, check which type of crystal vibrator is used and use the same type.

• Note on Replacing The EEPROM

After the EEPROM was replaced, write various parameters in the “TEST MODE E” (base unit: see page 14, handset: see page 16). (For the ID, see “Writing ID Numbers” described below)

Note: Replacing the EEPROM causes all data such as customer registered recording messages, caller ID data (only when replacing EEPR OM in base unit)

and telephone directory (base unit or handset) to be cleared.

RE-REGISTERING ALREADY REGISTERED SET

Initialize the registered information on base unit and all handsets, and then register again all handsets starting with handset 1 by the method given below. When re-registering the handset, refer to “Registering additional cordless handsets” in the instruction manual. (see page 8)

– Base unit –

1. Turn the power on.

2. Press three keys of [1], [EZ ACCESS], and [INTERCOM] simultaneously to set the test mode.

– Handset –

1. Turn the power on.

2. Press three keys of [1], [EZ ACCESS], and [INTERCOM] simultaneously.

WRITING ID NUMBERS (for additional handsets)

The ID numbers are given in decimal notation on the bottom of base unit. If handsets are added, ID can be written in the TEST mode, but the TEST mode handles ID numbers in hexadecimal notation, thus requiring decimal numbers to be con verted into he xadecimal numbers. Accordingly, when adding the handsets, refer to “Registering additional cordless handsets” in the instruction manual. (see page 8)

However, if the EEPROM was replaced, the handsets cannot be registered by the method mentioned above. In such a case, enter various parameters except ID numbers in the “TEST MODE E”, and then register the handsets by the method given in the instruction manual. Also, the ID numbers can be written in the “TEST MODE B”(decimal number) (base unit: see page 15, handset: see page 17).

Registering additional cordless handsets

The phone system includes a cordless handset. You can expand the system including a total of four cordless handsets. Be sure to register the ID number of the additional cordless handset called “station number” to the base phone before using the additional cordless handset. 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.

Before you start registering, set all the unit of the system in standby mode and place them close to each other (within a distance of 12 inches). Then do the following procedure only on the additional cordless handsets one bye one.

Caution

Do not register two or three cordless handsets at the same time. Doing so may result in more than one cordless handsets having an identical station number.

Registering additional cordless handsets (continued)

Enter the 10 digits system ID by pressing the dialing keys.

The system ID is shown on a sticker affixed to the bottom of the base phone.

Press (PGM).

You hear a long confirmation beep and the assigned station number is displayed.

Notes

• Do not allow more than 60 seconds to elapse during the operation procedure.

• Once you add a cordless handset to the base phone system, you cannot change the station numbers, or cancel the additional registrations.

• When you press any button other than (PGM) to use an unregistered cordless handset, the message “PLEASE REGISTER THIS HANDSET” will appear on the display, and five short error beeps will be heard. You must first register the cordless handset you want to add to the system.

• If you try to register a cordless handset which you have already added to the system, the five short error beeps will be heard and the registration will be canceled.

• If the registration is unsuccessful, “ERROR” will appear on the display, and five short error beeps will be heard after (PGM) is pressed in step 4. Move all the cordless handsets closer to the base phone, and then start over the procedure.

To check the station number assigned to the additional cordless handset

The station number of the cordless handset appears on the display of the cordless handset while it is seated on the charger. You can also utilize the supplied sticker of the station number and attaching on the cordless handset. (For details, see Operating Instructions of SPP-H273.)

[0] to [9] input 0 to 9 [HOLD] input A [INTERCOM] input B [CALL WAITING/FLASH] input C [EZ ACCESS] input D [ERASE] input E [REDIAL/PAUSE] input F [PGM] check sum [#] enter [*] reset

Enter the data associated with each address by referring to the “EEPROM data” in the following table.

Writing procedure:

1. Input the address number (3 digit) of EEPROM.

2. Press the [#] key to enter the address number and display read data (8 digit=4 byte).

3. If rewrite the data, input the rewriting data (8 digit=4 byte).

4. Press the [#] key to enter the rewriting data.

5. To release this mode, press the [OFF] key.

6. INITIALIZE THE EEPROM

In the test mode idling status, EEPROM (IC122) is all cleared except VP setting value when the [ERASE] key is pressed. When execute this operation, it erases stored data (phone dictionary, caller ID, message data).

Note:

ID1, ID2 : ID numbers in hexadecimal notation (refer to “5. TEST MODE

C-sum : Check sum value (After entering the data up to 3 bytes, press

OWN-No.: Self number of handset H-No. : Number of registered handset M-No. : Number of model destination (SPP-S2730: 80h)

B”)

the [PROGRAM] key to start automatic calculation)

5. TEST MODE B (Writing the ID number)

Note: Though the “TEST MODE E” handles the ID numbers as hexa-

decimal numbers, the “TEST MODE B” handles them as decimal

numbers. Both are different in numerical notation format only , and

net values are same.

The ID numbers written on the bottom of base unit are decimal

numbers, and accordingly use the “TEST MODE B” when enter-

ing the ID numbers.

In the test mode idling status, press the [7] key to activ e this mode and display as below.

display example

TEST B 224****** ID=224

*: Already registered ID number

[]: Inputted ID number (initial values are all blank)

[][][][][][]

IF a wrong ID number was entered by mistake, press the [OFF] key to return to the test mode idling status, then re-enter correct ID number.
