1-8. The number can then be changed if necessary and then transmitted by pressing SND.

Telephone numbers can also be programmed by your system oper- ator. A unique identification can then be stored in the unused positions of each 14-character location. For example, if the number has seven digits, the seven-character identification “RICHARD” can be stored with the number. Then when the number is recalled, “RICHARD” is flashed in the display followed by his telephone number. Each number programmed by your system operator can also be programmed so that you cannot change it. If you do change a number with a unique identification, the identifica- tion is erased and cannot be reprogrammed from the keypad. You must take the transceiver back to your system operator to have the identifica- tion reprogrammed.

Terminating a Call

When a conversation is finished, it is good practice for one of the parties to terminate the call by transmitting the # character. When the phone mode is exited by pressing the PHON key, this character is sent automatically. The # key can also be pressed to send this character. Three beeps sound to indicate that the system has detected the end of the call. Terminating the call in this manner prevents additional billing that may occur for the time it takes the system to automatically detect the end of a call.
