When the desired phone number is entered, press CFM to
confirm.
The WRONG tag will blink if the user tries to confirm an
incorrect number (the first digit of the number has to be on
the first position and the “-” character have not to be present
in the middle of the number). The WRONG tag will disap-
pear only when a digit of the phone number is modified.
Two cases have to be distinguished when the cellular module
connection is selected.
1) If one or two phone numbers have been set in items P.02
and P.03, then when the connection is activated (when
“CELL” is confirmed on item P.00), the two numbers will be
saved on the SIM card of the instrument with the codes
“HI504PH1” and “HI504PH2” and the GSM module ini-
tialized.
During the saving of the phone
numbers, “CELL” and the MEM
tag will blink alternatively on the
LCD.
Note The numbers are saved on the first two locations of the
phonebook area in the SIM card. If there are other phone
numbers previously stored on these locations, they will be
overwritten. If only one phone number is entered in item P.02
(or P.03) then the location correspondent to the other num-
ber on the SIM card phonebook area will be automatically
erased.
2) On the other case, if no phone number has been set in
items P.02 and P.03 (both the items filled with “- - - - - - -
- - - - - - - - - - - - -”), then when the connection is
activated (when “CELL” is confirmed on item P.00) the in-
strument tries to read the SIM card looking for some num-
ber associated with the code “HI504PH1” or “HI504PH2”
(previously saved by the instrument on the SIM card). If it
finds any, then the phone number(s) will be loaded by the
instrument (items P.02 and P.03 automatically updated),
By pressing the key, the first digit will be fixed on and it will
be possible to select the next digit.
When the fourth digit is reached, by pressing the key again,
the number on the primary display will scroll of one position
to the left and the fifth digit of the phone number will be
shown on the fourth position. The minus sign in the front of
the number disappears because the shown digits are not the
first four ones anymore.
By pressing the æ or key it is possible to modify the value
of the blinking digit and pressing the key it is possible to
skip to the next digit. When the end of the phone number is
reached, the user has to fill the remaining positions with “-”
character.
The space reserved for a phone number is of 20 digits. When
the last position is reached, by pressing the key, the pri-
mary display will return to the first four digits (recognizable by
the minus sign in the front of the number). In this way it is
possible to run cyclically through the number by pressing
repeatedly the key.
