6.14 SELECTIVE CALL
At analog mode channel, radio starts a call to another radio by dialing selective call
number. This call's difference from general call is to warn that user to listen carefully. This
call is heard by all radios at the channel.
ANI: Radio's identity info.
SC: Radio's selective call number.
ACK: When radio gets a selective call it sends this number the radio to inform that it has
got the call.
Against the caller radio ANI number and SC number of the radio that it is calling, called
radio responds with its ANI number to inform the caller radio that it has received the call. If
selective call is started to a group ACK is not waited. ANI, SC tone sequences are
displayed as the talking radios identity. To be abler to make selective call radio must be
authorized and at channel parameters, ANI at that channel must be marked.
When SC is received by a radio only the caller radio's ANI info appears at the display.

SC number is given to the radios that have selective call property. SC number is a 2-6 digit
number and can be selected by programming. Each radios SC number is given by a
method that when the last digits are used together it creates a group. In this case groups
are obtained with user number 9, 99, 999, 9999, 99999. SC started to group means that
the call is started to every radios whose SC numbers are starting same. During
programming, group tone at group identity entrance is determined as "0" or "A":
If group tone is programmed as "0" identity is entered as 22000.
If group tone is programmed as "A" identity is entered as 22GGG. thus caller radio dials
group identity as 22***.
To start selective call '#' key is pressed at analog mode and SC number of the other radio
is entered at the screen. Call has begun as soon as the all digits are entered.
While dialing the SC number, the number at the left side of the cursor is deleted by
pressing
button.
6.15 TONED CALL
At analog mode channel, if channel is being shared by a lot of user, toned call is used to
achieve communication of the user groups without listening each other when the channel
is not busy. If Tone Code Squelch/Selective Call is disabled by Monitor/Option Button
whole communication at the channel can be listened.
By tone Code Squelch, tone is added to channel's receiver and transmitter frequencies.
Radio receiver only turns on when it gets this tone. Channel tone info is entered with the
frequency info during programming.
6.16 REGISTERING
Radio must be registered to the system to be able to get service from system channels.
After turning on the radio and entering PIN info, radio is registered to the system
automatically. Registered site is appeared at the lowest row of the radio's display.
If radio get out of the site coverage area and enter another site's coverage area it
registered to the new site automatically. Thus user can get service from new system
without changing the channel.
6.17 CALLER IDENT
Radio displays the caller radio's system ident at system or direct mode digital channels; at
analog channels it displays the caller radio's ANI number. For analog ANI display, radio
ANI display must be programmed to the radio.
6.18 REPEAT CALL
If call short message can not be sent because of a barrier it has repeated for 4 times to
establish communication.

6.20 CHANNEL SCAN
When the radio user is at direct mode channel, it can take the other direct mode channels
to its scanning list and watch if there is a call at any of them. It checks the direct mode
channels that take place in the "channel scanning list" and if there is any broadcast in one
channel, let user to listen to that channel. When any call is received it can respond from
that channel with in scanning delay period (0-10sec). At the end of the time turns back to
its channel and goes on scanning.
Channel scan list can be occurred for all 300 channels or a certain part. At analog usages,
if there is broadcast in more than one channel 2 leveled priority can be given according to
its own priority order. Priority scanning is not valid during digital channels scanning.
While communicating at analog mode, if a call has received from priority channels, radio
passes to the priority channel. 1st and 2nd priority channel can be defined. If channel list
becomes longer it will take time to turn back to the first channel to check.
Channel scan process is started and ended by pressing scanning button that take place at
