Menu (2): Edit Call Book
The call book is required to be used in point-to-point networks.
The call book is an option in point-to-multipoint networks, but the Network ID feature is strongly recommended in most
applications.
The call book is an innovative feature that offers both security and exibility in use. The call book accomplishes this by
allowing the user to determine with which radio it will communicate based on the call book numbers for both the master
and remote. The radio modem’s call book number is unique. It is identied on the radio setup menu and a label on the
outside of the unit.
Using call book for a point-to-point system.
•The master call number must be listed in the remote call book or slave security is disabled in the remote.
•The remote call number must be listed in the master call book.
•The master entry to call must be set to the remote to call or call all.
To call a remote through one or two repeaters, you must call that remote directly (as opposed to using the call all option).
When call all is selected the master is not able to connect with any remotes through repeaters. This is because the master
calls every remote in the list when instructed to call all and will connect with the rst remote to respond. When establishing
a RF link through a repeater, the master must rst establish a RF link with the repeater, and then establish a RF link with it
prior to making contact with the remote.
Using call book for a point-to-multipoint system.
•The master call number or repeater call number must be listed in the remote or repeater call book.
•The master call book is not used in a point-to-multipoint system.
•At times it may be desirable to force a remote to go through a specic multiPoint repeater. In this scenario, the
remote call book should contain only the call number for the repeater to call on line 0 of the call book.
Entering or modifying call book numbers in the call book.
•Select the entry number (0 – 9) you wish to change.
•When prompted “Enter New Number”, enter the 7 digit call number of the unit to call (the dash is automatically
inserted).
•Enter the Repeater1 in a Point-to-Point Network. If no repeater is to be used or this is a Point to Multipoint
Network, press “ESC” to return to the modied call book menu screen.
•Enter the Repeater2 in a Point-to-Point Network. If no Repeater2 is to be used, press “ESC” to return to
the modied call book menu screen.
