SAFETY INFORMATION
The operator of any mobile radio should be aware of certain hazards common
to the operation of vehicular radio transmissions.
A list of the possible hazards are:
1. Explosive Atmospheres
Just as it is dangerous to fuel a vehicle with the motor running, be sure
to turn the radio OFF while fueling the vehicle. Do not carry containers
of fuel in the trunk of the vehicle when the radio is mounted in the
trunk.
2. Interference To Vehicular Electronic Systems
Electronic fuel injection systems, electronic anti-skid breaking
systems, electronic cruise control systems, etc., are typical of the types
of electronic devices that may malfunction due to the lack of protection
from radio frequency energy present when transmitting. If the vehicle
contains such equipment, consult the dealer for the make of vehicle
and enlist his aid in determining if such electronic circuits perform
normally when the radio is transmitting.
3. Electric Blasting Caps
To prevent accidental detonation of electric blasting caps, DO NOT
use two-way radios within 1000 feet of blasting operations. Always
obey the "Turn Off Two-Way Radios" signs posted where electric
blasting caps are being used. (OSHA Standard: 1926.900)
4. Radio Frequency Energy
To prevent burns or related physical injury from radio frequency
energy, do not operate the transmitter when anyone outside of the
vehicle is within two feet of the antenna.
CAUTION
Before jump starting or changing the vehicle
battery, it is strongly suggested that the 3A fuse
located in the Yellow lead (IGN A+) be removed.
This will insure that the radio is protected from
damage during the battery charging process.
Replace fuse when charging is completed.

INTRODUCTION
This manual describes how to use the Orion Mobile Radio. The Orion is a
synthesized, microprocessor-based, high performance mobile FM radio
providing reliable two-way communications in both the Enhanced Digital
Access Communications System (EDACS) trunking environment and
conventional communication systems.
In the EDACS, or trunked system mode, the user selects a communications
system and group. In this mode, channel selection is transparent to the user
and is controlled via digital communication with the system controller. This
provides advanced programmable features and fast access to communication
channels.
In the conventional mode, the user selects a channel and directly
communicates on that channel. In this mode, a system refers to a set of
channels. A channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the
radio's programming and the particular radio system. Most features described
in this manual may be enabled or disabled through programming. Consult the
system administrator for the particular features that are programmed into the
Orion.

USER INTERFACE
The Orion operating controls are located on the radio's front panel (See
Figures 1 & 2). A keypad, vacuum florescent display for radio status
information, and a microphone jack are on the front panel. The front panel
also provides a rotary SYSTEM/GROUP/CHANNEL knob, POWER ON-
OFF/VOLUME control, a ramp up/ramp down control, Scan add/delete
control, and a SCAN ON-OFF control for scan operation.
The keypad is used for manual number entry for individual calls, access to a
telephone interconnect system and activation of various EDACS or
conventional features such as menu selection. Each key has an associated
LED for status indication.
The display has two lines with eight alphanumeric-characters used to show the
operational mode of the radio. There is one LED for indicating transmitter ON
and one LED to indicate CHANNEL BUSY located below the POWER ON-
OFF/VOLUME Control.

CONTROLS
This section describes the buttons, keys and rotary knobs used to control the
Orion Scan and System Model radios. All functions and controls of the Scan
radio operate the same as the corresponding functions and controls on the
System radio. The Scan radio is equipped with a 4-button keypad and the
System radio is equipped with a 16-button keypad.
Many of the control buttons and keys have or can be programmed to have a
primary function and a secondary function. The SCAN button can be
programmed (as a secondary function) to toggle the keypad keys between
their primary function and their secondary function.
POWER ON-OFF VOLUME KNOB
This rotary Knob applies power to the radio and adjusts the
receiver volume. Rotating the control clockwise out o
f
detente applies power to the radio. A single alert tone
sounds (if enabled through programming) to indicate the
radio is operational.
Rotating the control clockwise increases the volume level. Minimum volume
levels may be programmed into the radio to prevent missed calls due to a low
volume setting. While adjusting the volume, the display will momentarily
indicate the volume level (i.e. VOL = 31). The volume range is from a
minimum level of zero (displayed as OFF in the display) up to 31 which is the
loudest level.
SYSTEM/GROUP CHANNEL KNOB
This rotary knob selects the systems or groups/channels,
depending upon programming. This 16 position knob has no
stop. See SYSTEM/GROUP/CHANNEL SELECTION
for more details.
RAMP CONTROL
The primary function of this rocker type button is to scroll
through the System list or the Group/Channel list depending
upon programming. The secondary function is to increment or
decrement items within a list (phone list for example). Press ,
to scroll in increasing order and press .to scroll in decreasing
order. To auto-ramp, press and hold the button.
8

SCAN ON/OFF
The
p
rimary function of this button is to toggle scan operation on
and OFF. When the radio is scanning, the SCAN LED is on an
d
all groups or channels in the scan list of the currently selected
systems are scanned.
The secondary function of the SCAN button is to toggle the keypad buttons
between their primary function and their secondary function.
SCAN ADD/DELETE
This rocker type button is used to display the current SCAN
status for a group/channel and then either add or delete the
group/channel from the system scan list.
The add button will select the last scanned channel recall b
y
p
ressing it twice when the radio is actively receiving or three
times when the radio is not actively receiving.
INDICATORS
Transmitter enabled - ON when the radio is transmitting.
BuSY - On indicates a carrier is being received (the channel is
b
usy). Note that if the selected channel is programmed fo
r
Channel Guard (CG), Digital Channel Guard (DCG) or Type 99
(T99) tone decode operation, the radio will not un-squelch if
a
valid tone or code is not received; the BSY indicator will be on.

Figure 4 - Orion Scan Model Keypad
KEYPAD
The keypad is similar to a telephone keypad but with four (4) additional
buttons on the side for a total of 16 keys. In addition to numbers (1-9, *, 0 and
#), which is a secondary function, most of the keys have or can be
programmed to have a primary function. A symbol or abbreviated word
describing its primary function is labeled on the keycap. Each labeled keycap
is associated with a radio feature (or primary function). The radio must be
programmed to operate with the Standard or the Optional keycap
configuration.
A key light (LED) is associated with each key or button. This may light when
the associate function is active. In some conditions the key light may blink to
indicate an action status.
The keypad key functions can be remapped to any of the primary function
keys using the PC programming software. It is suggested that the blank
keypad (located at the back of this manual) be completed if the keypad key
functions are changed.
Standard Keycap Configuration
The Standard keycap package for the System radio includes five (5) labeled
keycaps (MODE, HOME, CHN, AUX1 and AUX2) and six (6) blank
keycaps, which can be placed on any of the five key locations (numbers 3-6
and 9) shown in Figure 5. The keycap represents the primary function
programmed for that key location. See the Key Description section for a
description of the primary function associated with these five (5) keycaps.
The Standard keycap package for the Scan radio includes five (5) labeled
keycaps [MENU, CLEAR, SELECT, EMERGENCY ( E), OPTION] and five
(5) blank keycaps, which can be placed on any of the four (4) keypad keys.
The keycap represents the primary function programmed for that key location.

button is pressed). This indicates the radio has been assigned a working
channel or that the radio is transmitting on a conventional channel and voice
communication may begin immediately. In conventional mode, this tone may
be delayed after the PTT button is pressed due to G-STAR signaling (if
enabled through programming).
AUTOKEY (TRUNKED MODE ONLY)
After being placed in queue or releasing the PTT button prior to a working
channel assignment, the site calls the radio when a channel becomes available.
At this point, the radio automatically keys the transmitter (autokey) for a short
period to hold the channel. The radio sounds a mid-pitched tone when it is
clear to talk; immediately press the PTT button to keep the assigned channel.
CALL QUEUED (TRUNKED MODE ONLY)
A high-pitched tone after pressing the PTT button indicates the system has
placed the call request in the queue. The receiving unit(s) also hear the tones,
indicating they will receive a call shortly. If the PTT button is released, the
radios will autokey whenever a channel becomes available (see Autokey).
SYSTEM BUSY (TRUNKED MODE ONLY)
Three low-pitched beeps will be heard if the radio is keyed when the system is
busy, if no channels are available for sending the message, if the call queue is
full, or if an individual call is being attempted to a radio that is transmitting.
Releasing the PTT button and re-keying initiates a new channel request.
CALL DENIED (TRUNKED MODE ONLY)
If the radio is keyed and a low-pitched tone is heard then the radio is not
authorized on the system that has been selected.
