8. Press PAGE if you want to attach a message to the call.
9. Press CHAN if you want to initiate the call on a specific channel.
10. Press SEND or ENTER to initiate the call.
The radio now starts the AnyCall process. During this process, you will see TO alternating with
the number of the channel on which the request is being sent.
NOTE
You can press STOP or ESC to abort the entire process.
When an AnyCall is transmitted, the initiator of the call receives an indication of each station
answering the call (its address flashes in the display, until replaced by the next answering
station).
11. After a programmed interval (or after 16 stations answer, whichever comes first), the link is
established. Now you can start talking.
12. To end the call, press ESC.
2-12.3.4.10 Transmitting Wildcard Calls
Wildcard calls, that is, calls in which the destination address includes the wildcard character ?, let you
to simultaneously address multiple stations with a single address:
• Any station receiving an address with wildcards stops scanning and checks the address length: if
the number of characters in the received address is different from the number of characters in its
own self-address, the station ignores the call.
• If the received address matches the length, a receiving station checks the significant positions in
the received address against its own. For example, the stations JOHN and JOIN will both accept
a call with the address JO?N.
• Each station accepting the call answers the calling station in a pseudo-random slot.
Micom-Z will wait for responses for a certain time before entering the link state with all the stations
that responded within this interval (the maximum number of stations that are accepted in a wildcard
call is 16). Therefore, with the wildcard option, the link set up process takes more time, because the
radio waits longer to get responses (it cannot “guess” the number of stations that will answer).
Before continuing, you may wish to review Appendix A, which presents details on ALE addressing
(including the use of wildcards in addresses).
NOTE
Before starting, you may want to select a different net to use: see
instructions on page 2-35.

If you see the address you want (that is, you want to repeat the last wildcard call), skip directly
to Step 11 below, otherwise continue as explained below.
2. Press MORE once.
3. Press MULT to display the first page of special calls.
