Note on Replacing The EEPROM
After the EEPROM was replaced, write various parameters in the “TEST MODE E” (See page 17). (For the ID, see “Writing ID Numbers”
described below)
Note: Replacing the EEPROM causes all data such as customer registered telephone directory to be cleared.
NOTE ON CONNECTING THE PANEL FOR SPP-A2780 FOR TEST MODE (Base Unit)
Some items in the test mode and electrical adjustments of this set require 12 keys for data writing, but this set does not provide 12 keys.
Accordingly, the panel (BASE CABINET (UPPER) ASSY) for the SPP-A2780 is connected for these items, but the connector CN302 for
panel connection is not mounted on the BASE MAIN board in this set.
Therefore, in performing the test mode and electrical adjustments, the connector CN302 must be additionally mounted, and it need not be
removed after use, as the patterns of the board could be damaged when removing the connector. However, note that it may be a little
difficult to close the cabinet with the CN302 left mounted because of a narrow internal space.
Further, additional mounting of the CN301 for the SPP-2780 panel connection besides the CN302 enables the LCD display. Also, in this
case, the CN301 need not be removed after repair.
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 10)
– Base unit –
1. Turn the power on.
2. Press three keys of
[1]
,
[EZ ACCESS]
, and
[INTERCOM]
simultaneously to set the test mode.

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 converted into hexadecimal numbers.
Accordingly, when adding the handsets, refer to “Registering additional cordless handsets” in the instruction manual. (see page 10)
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).
