the
[PROGRAM]
key to start automatic calculation)
OWN-No. : Self number of handset
H-No.
: Number of registered handset
M-No.
: Number of model destination (SPP-A2770: 40h)
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 active this mode
and display as below.
*
: 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.
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 dictio-
nary, caller ID, message data).
