3.4 Name / Number Storage and Display
The PTA12-300 can store up to 16 sets of data, each consisting of two lines: the first line has an identifier
(address number) followed by a name and the second line is the associated telephone number.
Each name line starts with the two-digit address number (01 through 16) followed by a colon and has up
to 13 character spaces available to store the alphanumeric name. There are up to 16 character spaces
for the phone number. The display only shows name or number information at one time. In Recall mode,
pressing the
← (#) or → (½) buttons will toggle from name to number or number to name. Full information
on storing and editing information is provided in Section 3.5.3.
Note:
The # and * buttons may not be used in either the name or number since these buttons are used
as ← and → when the PTA12-300 is in edit mode.
3.5 Modes of Operation
Upon initialization, the PTA12-300 is in a Default Power-Up mode and the display will show PTA12-300
X.XX.X, where x.xx.x is the firmware revision number. The unit will automatically enter this mode at power
up, or when reset. From Default mode, 3 different modes of operation may be selected: Call mode, Recall
mode or Edit mode (see Sections 3.5.1 through 3.5.3).
3.5.1 Call Mode
The PTA12-300 is put in Call mode by pressing the HOOK button. The green HOOK LED will illuminate,
the display will show Call Mode (if entered from Default Power-Up mode) and the keypad can then be
used just like a telephone to dial numbers.
3.5.1.1 Making a Call in Call Mode
In Call mode (hook switch active) the number (0 through 9) and symbol (½, #) buttons on the keypad are
used to ‘dial’ the required telephone number by generating the corresponding DTMF tone on the POTS
output. The digit that has been pressed is shown on the display and the corresponding DTMF tone is sent
immediately. The whole number is retained on the display for visual confirmation that the correct number
has been dialed. Pressing the HOOK button again terminates the call, turns off the green hook LED, and
returns the unit to default mode.
As each button is pressed, audible confirmation is provided on the sidetone of the headset output.
For a summary of button functions available in Call mode refer to Table 2 in Section 3.6.
3.5.1.2 Receiving a call
The hook LED will flash to signal an incoming call. To answer, press the HOOK button (putting the unit
into Call mode). The hook LED will then illuminate steady green until the call is terminated by pressing the
HOOK button again.
