On-Off/Volume - Pressing this knob turns power on and off. Turning it sets the volume level. The vehicle ignition

switch may also control power and have to be on. Refer to “Power Turn-Off Delay” on page 13 for more information.
If the remote control unit is used with a front mount transceiver to provide dual controls, the volume level may be
the combined setting of both units.

Select Switch - This is a dual-function switch that changes the selected system or group and selects information in
the Menu mode (see page 18).

When selecting systems or groups, a bar above the system and group digits indicates which is currently being
changed. To switch this bar between digits, press the Select switch. Then to increase or decrease the selected system or
group number, turn this switch clockwise or counterclockwise. Only systems and groups in the current bank can be
changed (see page 12). A tone sounds each time the system or group changes (unless tones have been disabled).

The transceiver can be programmed so that the bar defaults to either the system or group digit when power is
turned on or after a digit is changed. In addition, the time that must elapse before it returns after a digit change is
programmable for 1-15 seconds or infinite.

Option Switches - Up to six option switches can be programmed by your system operator to control various func­tions. A label on the switch identifies the function it controls. The option switch functions are described starting on
page 18.

conventional) can be programmed.

Alphanumeric Display - This 10-character area of the display indicates a unique identification for the selected group.
For example, “GAS TRUCK” could be displayed when a certain group is selected. It also displays various error and
status messages.

Status Display - These two characters indicate the following status information:

Rotating clock-like symbols in both positions indicate that scanning is occurring.

This symbol in the left position indicates that the displayed system is in the scan list. Likewise, this symbol in the
right position indicates that the displayed group is in the scan list.

This symbol in the right position indicates that group scanning is occurring.

P1/P2 - When a conventional system is selected, “P1” indicates that a message on a priority 1 group is being re­ceived, and “P2” indicates that a message on a priority 2 group is being received. Refer to “Priority Group Sampling”
on page xx for more information.

ON/OF - When the menu mode is selected by the MENU switch, “ON” indicates that the displayed parameter is
active, and “OF” indicates that it is inactive.

- Indicates that the function controlled by the option switch above it is active. For example, this symbol below the
Scan switch indicates that the scan mode is enabled. Only certain switches require this indicator.

STANDARD MOBILE-TO-MOBILE CALLS

Introduction

The standard mobile-to-mobile call is the type you will probably make most often. This type of call is between you
and another mobile or control station in your radio system. The main difference between this call and the telephone and
special calls described in the next section is that no number is dialed when it is placed.

Placing a Standard Mobile-To-Mobile Call

1. Turn power on and set the volume level if required.

2. If necessary, select the desired system/group using the front panel Select switch (see page x). The selected

system/group is displayed even when scanning.

3. If a conventional system is selected, the channel must be monitored before transmitting as described on page x.

4. Press the microphone PTT (push-to-talk) switch and operation is as follows with the various types of systems:

Multi-Net and LTR - If the short proceed tone sounds, the system is successfully accessed and speaking can begin.
Proceed to step 5.

If a busy condition exists, the busy tone sounds and “SYSTEM BSY” is displayed. If you keep the PTT switch
pressed, the system is accessed when it becomes available. Otherwise, try again later. If a Multi-Net system is selected
and the Busy Queuing feature is programmed (see page 13), the call goes into a queue when the PTT switch is released.

If an out-of-range condition exists, the intercept tone sounds and “OUT-OF-RNG” is displayed. Drive the vehicle
closer to the radio system or away from shielding structures and try again. If a Multi-Net system is selected and the
Auto-Registration feature is enabled, (see page 14), the transceiver automatically changes sites when an out-of-range
condition occurs.

Conventional - If the proceed tone has been enabled by programming, it sounds to indicate that speaking can begin.
However, the presence of this tone does not indicate that a busy or out-of-range condition does not exist (see “Con-
ventional Operation” on page 11).

5. Release the PTT switch and listen for a response. The PTT switch must be pressed to talk and released to listen.

When the conversation is finished, place the microphone back on-hook.

Receiving a Standard Mobile-to-Mobile Call

1. Turn power on and set the volume level if required.

2. Select the desired system/group using the Select switch. If the scan feature is available, you may also enable scan-

ning by pressing the SCAN option switch.

3. When a call is received, the display indicates the system and the group of the call. To respond to the call, take the

microphone off-hook and press the PTT switch. If scanning, the system/group on which a response occurs is
controlled by programming. See “Transmitting In The Scan Mode” on page 11.

4. The PTT switch must be pressed to talk and released to listen. When the conversation is finished, place the micro-

phone back on-hook.

TELEPHONE AND OTHER SPECIAL CALLS

NOTE: In order to place and receive telephone or special calls, your transceiver must have been programmed for
that service. In addition, you must have a microphone with a DTMF keypad (unless you call only pre-programmed
numbers).

Introduction

Telephone calls allow you to access the public telephone network, and special calls allow you to call specific
mobiles in your site or some other site. After the system is accessed, a number must be dialed using the microphone
keypad or recalled from memory using the Phone Mode (see page 15).

The following information describes how LTR/ Multi-Net telephone calls and Multi-Net special calls are placed
and received. If you can make telephone calls on conventional systems, the procedure may be slightly different. Your
system operator will then provide you with additional information.

Placing a Telephone or Special Call

1. Turn power on and set the volume level if required.

2. Take the microphone off-hook and note the displayed system/group. If necessary, select the desired system/group

using the Select switch. The handset symbol appears in the display when a system/group programmed for a tele­phone or special call is selected.

The Phone Mode may also be selected if you have the PHON option key or TELEPHONE menu parameter (see
page 15).

3. Press the PTT switch and then release it when the proceed tone sounds. If a dial tone then sounds, proceed to step

4. If a busy or out-of-range condition is indicated, proceed as follows:

Busy - A busy condition is indicated by a busy tone and “SYSTEM BSY” in the display. If a Multi-Net system is
selected and the Busy Queuing feature is available (see page 13), it automatically places the call in a queue when PTT
switch is released.

If an LTR system is selected, the Free System Ringback feature is automatically selected when the PTT switch is
released. This feature signals you when the system is no longer busy (see page 16 for more information).

Out-of-Range - If an out-of-range condition exists, it is indicated by an intercept tone and “OUT-OF-RNG” in the
display. If an LTR system is selected and the System Search feature is available (see page 16), it may be selected to
automatically search for a free system.

If a Multi-Net system is selected and the Auto-Registration feature is available (see page 14), it automatically
changes sites when an out-of-range condition occurs. If these features are not available, drive the vehicle closer to the
radio system or away from shielding structures and try the call again.

4. Dial the number using the keypad on the microphone. If the transmitter keys automatically when a number is

dialed, the PTT switch does not need to be pressed while dialing.

5. When you finish dialing the number, release the PTT switch if it was pressed.

With LTR calls, ringing of the other party is then heard. With Multi-Net calls, a short tone sounds to indicate that
the number was accepted by the system. Then, if it is a telephone call, ringing of the other party occurs (or a busy tone is
heard if the line is busy). If it is a special call, a second short tone sounds to indicate that speaking should begin. No
ringing of the other party occurs.

6. The PTT switch must be pressed to talk and released to listen. You cannot talk and listen at the same time because

no messages are received while the PTT switch is pressed.

7. When the conversation is finished, terminate the call by pressing the # key. Place the microphone back on-hook.

Receiving a Telephone or Special Call

1. Turn power on and set the volume level if required.

2. Select the system/group programmed for these calls or enable system scanning by pressing the SCAN switch (if

available).

3. When a ringing tone is heard, answer the call in the normal manner (press the PTT switch to talk and release it

to listen).

4. When the conversation is finished, terminate the call by pressing the # key. Three beeps indicate that it has been

terminated. Place the microphone back on-hook.

Calling a Mobile From a Landside Telephone

Mobiles can also be called from a landside telephone. With some radio systems, a mobile may have a unique tele­phone number so that it can be dialed directly. With others, the number of the radio system is dialed. Then when the
system answers, a beep sounds and the number specifying the mobile being called is dialed. This number is supplied to
you by your system operator, and it must be dialed using a tone-type telephone. Depending on the type of call being
made, a ringing tone then sounds or another beep sounds which indicates that speaking can begin.

SYSTEM SCAN

Introduction

The system scan feature monitors the programmed systems of the current bank. When a message is detected that
the transceiver is programmed to receive, scanning stops and the message is received. Shortly after the message is
complete, scanning resumes.

System scanning is turned on and off by the SCAN option switch (see page 3). When system scanning is enabled, a
triangle (

meric display (see “Multi-Site and Single-Site Scan” description on page 11). In addition, rotating symbols are present
in both status displays between the system and group numbers.

“Scan List Programming” which follows) or single-site scan is used. The selected system and group can be changed
while scanning using the Select switch in the normal manner. Scanning temporarily halts while the change is being
made.

be where transmissions occur (see “Transmitting in the Scan Mode” on page 11).

∆ ) is indicated in the display below the switch. The microphone must also be on-hook for scanning to occur

When system scanning is actually occurring, “SNGLE SCAN” or “MULTI SCAN” is indicated in the alphanu-

Scanning is sequential through the programmed systems unless they have been deleted from the scan list (see

When a call is received in the scan mode, the display indicates the system/group of the call. However, this may not

Scan Resume Delay

After a message is received or transmitted while scanning, there is a delay before scanning resumes. This delay is
programmable by your system operator for 0-7 seconds. The delay after a message is received prevents another message
from being received before a response can be made. The delay after a message is transmitted ensures that you hear a
response to your message instead of some other message occurring on another system/group.

There is also a scan continue timer that can be programmed by your system operator. If this timer is used, it sets the
maximum time that a message is received before scanning resumes. This can prevent scanning from being interrupted
for long periods by lengthy messages.

Scan List Programming

Systems and groups can be added to or deleted from the scan list if the transceiver is equipped with an A/D (add/
delete) option switch. The bar above the system or group indicates which changes when this switch is pressed. To move
this bar between the system and group displays, press the Select switch.

The scan list status of a system or group is indicated by an asterisk ( * ) in the status display. An “*” next to the
system number indicates that the displayed system is in the scan list and scanned normally. Likewise, an “*” next to the
group number indicates that the displayed group is in the scan list. When scanning is occurring, the scan list status is not
indicated because the rotating scanning indicators are displayed.

The displayed system or group can be deleted from the scan list while listening to a message on that system or
group. Scanning resumes shortly after the system or group is deleted. If the last system or group is deleted from the scan
list, the last selected group is still scanned.
