accomplished by pressing the transfer key before or after conversing with the extension to
which the call is to be transferred. It has the same function with the ‘Transfer’ option on the
screen.
• “Park” key:
A line or an internal conversation can be parked through this key during the
conversation. When the call is parked by using that key, “parked line” information and
‘Retrieve’ option for the line appear on the display. The call can be retrieved by pressing
the “Enter” key or by pressing the “Park” key for a second time. A call can be parked more
than once and more than one line can be parked at the same time. When a line has been
parked, the telephone can be used independently from that external conversation, i.e.,
internal and external calls can be made by making use of the entire features. For OP50
users, if there are parked line and also parked internal call and if the other service is
activated, the internal line call will be retrieved in turn with this key. (The first call which is
parked will be displayed in the first rank of the park list.)
The second function of this key is, on the other hand, providing the relation between the
exchange and the console. The key is employed when it is required to change the number
of the telephone or to reset the connection to the exchange. When the key is pressed until
the “beep” is received and then it is released, the telephone prompts for the extension
number to be put on the data line of the exchange. In order to enter the “Terminal no=AA”
value of OP50, this key is pressed consecutively to proceed until the correct extension
number is displayed and the extension number will have been entered to the telephone
upon lifting and then replacing the handset.
NUMERICAL KEY PAD
It is composed of 3x4 (DTMF) key matrix. Moreover, these keys are used for number or
character (letter, figure or symbol) entry during the operations related to the “Phone Book”.
If any programmable key is pressed when the letter entry is being made with capital letters,
the entry starts to be made by small letters. By the same way, if any programmable key is
pressed again, small letters turn into the capital letters. Grouping of the characters with
respect to the keys are as follows. Standards that apply for similar applications have been
complied with for this subject.
