2-12.3.4.8 Transmitting Group Calls
Group calls let you call several individual stations in your net (at least 2) at once. Thus, you can use a
group call to communicate with a few select stations, while other stations can still communicate at
will, using other channels available to your net.
You can call up to 5 stations in a group call. The only restriction is that the total length of all the
addresses cannot exceed 12 ALE words (36 characters). If the maximum allowed length is exceeded,
you get a BUFF FULL error.
NOTES
• If you need to check beforehand the length, remember that each
ALE word must include 3 characters. Therefore, when an address
is not an exact multiple of 3, stuffing symbols are automatically
added in the last positions.
• ALE addresses are categorized in accordance with their leading
ALE word (that is, their first three characters: if the address is short
and has only one or two characters, stuffing symbols @ are
added). When assembling a group you must also take into
consideration that the maximum number of different address
categories (as identified by their leading word) in one group is 5. If
more are included, then when you try to send the call you will see
UFA WRONG. In this case, remove addresses to make the group
more homogenous.
To make a group call, first you must specify the stations to be included in the group. The addresses of
the stations you include in the group can be saved as a group; the radio can store up to 4 different
groups. If a group including the desired stations is already programmed, you can directly initiate the
call to the desired group.
NOTE
Before starting, you may want to select a different net to use: see
instructions on page 2-35.
To transmit a group call:
1. Press CALL.
The radio displays the last called address.
If you see the group you want, skip directly to Step 6 below, otherwise continue as explained
below.
2. Select the GRP option as explained on page 2-39.
3. The first group displayed is always group 1. If this is the group you want, skip directly to Step 6
below, otherwise press the UP or DOWN arrows until you see the desired group.
4. Press PAGE if you want to attach a message to the group call.
5. Press CHAN if you want to initiate the call on a specific channel.
6. Press SEND or ENTER to initiate the call.
