This icon indicates that the screens shown are each displayed
momentarily in sequence.
SAFETY
1. Do OT operate your radio, without a handsfree kit, whilst driving a
vehicle.
2. Do OT operate your radio in an explosive atmosphere.
Obey the 'Turn Off Two-way Radios' signs where these are posted,
e.g. on a petrol station forecourt.
3. Do OT touch the antenna while the radio is transmitting.
4. Do OT operate the radio if the antenna has become disconnected
or damaged.
HI TS FOR USI G THE RADIO
• When speaking, hold the microphone a few centimetres from your mouth and
speak across it, rather than into it.
• Keep the length of your conversation to a minimum and replace the
microphone on it’s cradle after use.
• When it is possible to move location, avoid making calls from known poor
signal-strength areas such as the radio systems fringe areas (limit of range)
or from screened or shadowed areas, e.g. an underground car park or
underpass.
• To avoid unnecessary drain on the vehicle battery, keep the engine running
when using the radio for extensive periods of time.

1. I TRODUCTIO
The SRM9000 Series Radios are advanced, versatile, Digital Signal Processor
(DSP) controlled, two-way mobile radios. The SRM9000 Series is available in a
number of frequency bands and versions for specific applications. This manual
describes the operation of the SRM9020 Trunked Alphanumeric Display variant.
The radio consists of a SRM9000 Transceiver Unit that may be mounted local or
remote, and a SRM9020 Alphanumeric Microphone which is designed to mount
within view and reach of the driver. A speaker connected to the radio provides
the audio interface.
The radio is software programmable and it can be customised to the operational
requirements of your particular fleet. Your Simoco representative can help in
programming your radio’s facilities to meet your present and future requirements.
This guide describes the operation of the SRM9020 facilities.
1.1 I STALLATIO
As the installation of your SRM9020 Radio is a technical and possibly hazardous
operation, we recommend that it is installed and set up for use by your dealer or
an authorised installer. However, if you need information regarding the correct
procedures for installation, please refer to the SRM9000 Series Installation
Instructions supplied with the radio.

4. CALL TYPES
The Trunking System allows the user to make a number of different types of call.
The SRM9020 supports most of the call types that can be accessed through the
Trunk Network, including.
• Voice calls between Individuals or Groups
• Include Calls
• Status Calls
• Priority and Emergency Calls
• Diversion Calls
• Broadcast Calls.
Individual Calls. Allow private conversations between two users. Other users
can be included in the call using an Include Call.
Group Calls. Allow different members of a group to participate in a group
conversation. Any participant in the group can leave the call individually, but only
the originator can end the call.
Status Calls. Allow a status number to be sent between users. The SRM9020
allows text messages to be associated with up to 30 status numbers and can
display these text messages when such a status is to be sent or is received.
Diversion Calls. Allow the user to divert incoming calls to another radio,
telephone, etc. Additionally the SRM9020 can call radios that are similarly
diverted. or example, when away from their vehicle, a user can divert calls to
the depot radio.
ormal, Priority and Emergency Calls. If the channel is busy, Normal calls are
placed in a queue and actioned when they reach the top of the queue. Priority
calls jump to the top of the queue unless a previous priority call is taking place.
Emergency calls are actioned immediately.
Broadcast Calls. Are similar to Group calls except that only the initiator of the call
can speak to the other parties in the call.
Notes 1: Some of these call types are only available after prior arrangement
with the Network Operator.
2: ost Trunk Networks have a time limit placed on call duration. The
Network terminates the call after this time.

4.1 B ASIC S TEPS I A V OICE CALL
The following basic steps need to be performed to achieve a voice call:
• User selects call recipient.
• Network allocates a channel, (may be a small delay).
• User and recipient take turns to speak.

4.3 R ECEIVI G A C ALL
The SRM9020 will respond to incoming calls according to the type of call being
received.
4.3.1 Receiving a Voice Call
When a call is received the radio will ring and display
the caller’s name or ID number and the animated
Call Progress icon.
While the radio is ringing, the user can answer the call by:
- Pressing and releasing the PTT button.
- Removing the Microphone from its bracket.
- Pressing the S button.
When the call is answered the handset will
momentarily display the message Q-ED (QueuED)
followed by the Elapsed Call Time (Min-Sec) and the
Audio Enabled icon.
A conversation can now take place by each operator, in turn, pressing their PTT
buttons to speak and releasing them to listen.
When the call is finished, either operator can end the call by:
- replacing the Microphone on its bracket, or
- pressing the button.
If a ringing call is un-answered because the Network times out, or the caller
cancels the call, details of the call are saved in the Stored Calls Screen.

and Emergency calls.
Note 2: Some Trunking Networks provide a different Call-Set-Up method
which allows the radios to automatically answer incoming Voice
Calls.

4.3.2 Receiving a Group Voice Call
A Group Voice Call differs from an individual call in that the operators do not need
to answer the ring tone. All radios that are members of the Group automatically
connect to the group call.
Whilst in a Group Call, all operators can PTT, in turn, and talk to each other. Only
the Originator can Clear the call to release the channel. Any operator can leave
the Group Call in the same manner as ending a normal voice call.
Note 1: In some Trunk Networks, operators who leave a Group Call are
returned to that Group Call after a short period of time. This “Late
Joiner” Network facility allows users that were previously engaged on
another call, or out of coverage, to join a Group Call that is in
progress.
Note 2: A Broadcast Call is a special type of Group Call in which only the
originator can speak. All other group members are inhibited from
transmitting. Broadcast calls are originated using dialstrings entered
on the keypad.

4.4 M AKI G A S TATUS C ALL
Status Calls allow a Status Number to be sent between users. This “status
number” can have a specific meaning/text message assigned to it.
e.g. 1 may mean : “On Job”
2 may mean : “Lunch”
14 may mean : “Return”, etc.
The SRM9020 automatically associates the number with the pre-programmed text
when a Status is to be sent or received.
• Scroll through the Phone book until the recipient’s name is displayed.
• Using the M button, move to the Status Screen.
• Use the buttons to scroll through the entries until the desired
message is displayed.
• Press the S button to send the Status Message.
This is a very quick and efficient method of sending information and is extremely
advantageous in a heavily populated system.
4.4.1 Incoming Status Messages
Incoming Status Messages are stored, and can be viewed, in the Stored Calls
Screen.
If not already displayed, the icon appears on the Main Phonebook Screen and
a short ‘bip’ is emitted to alert the user that a new message has been received.

4.5 C ALL D IVERSIO
Incoming calls can be diverted to another radio, telephone, or PABX extension,
using the Call Diversion facility provided by the Trunk Network. Normally, Call
Diversion is only available after prior arrangement with the Network Operator or
System Owner.
Providing that the command has been pre-defined by the PP, a diversion may
be set up via a Phonebook Entry.
4.5.1 To Cancel a Diversion
A call diversion may be cancelled by selecting the ClrDiv option from the
Phonebook and pressing the S button.
4.6 E XTER AL ALERT
Provision is made to connect an external alerting device to the rear of the radio.
The external alert may be activated when a call is received (and cancelled by a
timeout, or by user intervention).
This function is enabled by software programming. When enabled, the External
Alert may be switched On or Off using a unction button, (typically F or
from the Phonebook menu).

5. ME U SYSTEM
The SRM9020 radio software uses a programmed Menu structure to enable the
operator to access all of the radio options. The structure of the menu can be
programmed to meet the specific needs of individual customers. The diagram
below illustrates the default menu structure for which the radio is programmed at
manufacture.
This diagram displays all of the available options.
The number of options and the order in which they are
accessed will vary between individual installations.
