Entering or Modifying Numbers in the Call Book
Entering or modifying call book numbers in the Call Book is a straightforward process. When in the Call Book menu, select the entry number (0 – 9) you wish to edit. You will be prompted for the new number (formatting is automatic, you do not need to enter the dash). Once the number is entered (unless it is 000-0000) you will be asked for the call number of the first repeater to be used. If no repeater is to be used, enter the escape key; your entry will be complete and you will be back in the Call Book menu screen. If you enter a repeater number, you will then be prompted for the call number of the second repeater to use. If a second repeater is being used, enter the call number at this time; if not, enter the escape key. Once again, the radio modem will retain your entries, as shown in the updated Call Book menu screen.
Note: It is important that the Call Book slots (0 – 9) are filled sequentially beginning with 0, the first slot in the book. Call Book numbers do not need to be entered in numerical order; however, there must not be any 000-0000 numbers in the middle of the list of good Call Book numbers. The reason for this is that when a master is instructed to Call All available remotes, it will call all remotes listed until it reaches the first number of 000-0000. If a valid call book number is entered after the all zero number, it will not be recognized as a valid number to be called by the master.
Edit Call Book in Multi-Point Systems
In a multi-point system, the remotes and repeaters are not listed in the master’s Call Book. When establishing such a system, it is necessary only to have the master’s Call Book number in each remote’s and repeater’s Call Book, and to have each repeater’s Call Book number in the Call Book of each remote which may potentially communicate through it.
The following example shows the Call Books of a multi-point system comprised of a master, repeater and remote in which the remote can communicate either through the repeater or directly to the master:
Multi-Point Master Call Book (Unit Call Book number 555-0001)
Entry | Number | Repeater 1 | Repeater 2 |
| | | |
(0) | 000-0000 | | |
| | | |
(1) | 000-0000 | | |
| | | |
No call book number entries are necessary in the master’s Call Book
The master’s Call Book may be programmed to call any entry
Multi-Point Repeater Call Book (Unit Call Book number 555-0002)
Entry | Number | Repeater 1 | Repeater 2 |
| | | |
(0) | 555-0001 | | |

| | | |
Multi-Point Remote Call Book (Unit Call Book number 555-0003)
