Chapter 1
Read Me First
This User Guide covers the basic operation of the radio. However, your dealer or system administrator
may have customized your radio for your specific needs. Check with your dealer or system
administrator for more information.
1.1
Notations Used in This Manual
Notations such as Warning, Caution, and Notice are used throughout the text in this publication.
These notations are used to emphasize that safety hazards exist, and the care that must be taken or
observed.
WARNING: An operational procedure, practice, or condition and so on, which may result in
injury or death if not carefully observed.
CAUTION: An operational procedure, practice, or condition and so on, which may result in
damage to the equipment if not carefully observed.
NOTICE: An operational procedure, practice, or condition and so on, which is essential to
emphasize.
The following special notations identify certain items.
Example Description
Home button or Buttons and keys are shown in bold print or as an icon.
Phone Menu entries are shown similar to the way they appear on the dis-
play of the radio.
This means “Press the right side of the 4-Way Navigation Button”.
1.2
Radio Care
Proper radio usage and care ensure efficient operation and long life of the product.
The following are suggestions to assist you in troubleshooting possible operating problems.
CAUTION: The cables that connect to the rear of the radio could have live voltage on some of
their pins. Do not remove or reconnect these cables. Only a qualified radio technician should
perform this task. Service performed by unauthorized personnel may cause the radio to transmit
an emergency alarm even if the unit is turned off.
If your radio is locked up or the display shows FAIL 01/09, power cycle the radio. If this does not
correct the condition, take the radio to a qualified radio technician for service.
If radio operation is intermittent, check with other persons using the system for similar problems before
taking the radio in for service. Similar problems indicate a system malfunction rather than a radio
failure.
If symptoms persist or if your unit exhibits other problems, contact a qualified radio technician.

1.2.1
Cleaning the External Surface of the Radio
Prerequisites:
CAUTION: Do not use solvents to clean your radio. Spirits may permanently damage the radio
housing.
Do not submerge the radio in detergent solution.
Procedure:
1Combine 1 teaspoon of mild dishwashing detergent to 1 gallon of water (0.5% solution).
2Apply the solution sparingly with a stiff, non-metallic, short-bristled brush, ensuring that excess
detergent does not get entrapped near the connectors, controls, or crevices.
3Dry the radio thoroughly with a soft, absorbent, lint-free cloth.
4Ensure that no water remains entrapped near the connectors, cracks, or crevices.
1.3
Additional Performance Enhancement
The following performance enhancements are some of the latest creations designed to enhance the
security, quality, and efficiency of the radios.
1.3.1
ASTRO 25 Enhanced Data
ASTRO 25 Enhanced Data is optimized to handle different message sizes and variable update rates
from different applications of the radio. To improve data channel efficiency and enable denser network
traffic, add Enhanced Data to the Integrated Data system with a software installation.
1.3.2
Dynamic System Resilience
Dynamic System Resilience (DSR) ensures that the radio system is seamlessly switched to a backup
master site dynamically during a system failure. DSR also provides indications such as failure
detection, fault recovery, and redundancy within the system. DSR also supports mechanisms related to
the Integrated Voice and Data (IV&D) or data centric.
68012006035-EM
Chapter 1: Read Me First
12

1.3.3
CrossTalk Prevention
CrossTalk Prevention feature prevents crosstalk scenarios and allows the adjustment of the internal
SSI clock rate of the radio. This reduces the possibility of radio frequency interfering spurs.
1.3.4
Encrypted Integrated Data
Encrypted Integrated Data (EID) provides security encryption and authentication of Integrated Voice
and Data (IV&D) data bearer service communication between the radio and the Customer Enterprise
Network.
1.3.5
SecureNet
SecureNet allows you to perform secured communications on an Analog or Motorola Data
Communication (MDC) channel. The MDC Over-the-Air Rekeying (OTAR) feature allows you to
perform OTAR activities on an MDC channel.
1.3.6
Over-the-Air Rekeying
The Over-the-Air Rekeying (OTAR) feature allows the dispatcher to remotely reprogram encryption
keys in the radio after a rekey request.
Single-system OTAR
Single-system OTAR allows a radio to be rekeyed by only one Key Management Facility (KMF) or
Key Management Controller (KMC).
Multi-system OTAR
Multi-system OTAR allows a radio to be rekeyed by multiple KMFs. After an initial programming, the
radio is able to seamlessly move to different secure systems associated to a newly selected
channel.
NOTICE: This feature must be preprogrammed by a qualified radio technician. Contact your
system administrator for more information.
1.3.7
P25 Digital Vehicular Repeater System
Motorola Solutions offers an MSI Certified APX compatible, third party, P25 Digital Vehicular Repeater
System (DVRS) that provides low-cost portable radio coverage in areas where only mobile radio
coverage is available and portable radio coverage is either intermittent or non-existent.
The system sends DVRS firmware and configuration updates over-the-air. The following scenarios
occur during the update:
• If the update is accepted, the display shows Updating DVRS.
• If the update fails, the display shows DVRS updt failed. Contact your system administrator for
more information.
NOTICE: Portable subscriber units enabled in the system for Radio Authentication shall be able
to authenticate regardless of whether they are communicating directly on the system or by
using a DVRS.

1.3.8
Conventional Talkgroup and Radio Scan Enhancements
Enhancements have been made to the Conventional Talkgroup at the system to improve the Scan
feature operation significantly when multiple agencies are using a single conventional radio frequency
channel.
These enhancements allow you to use Selective Squelch to operate on only the subset of talkgroups
that are relevant to the users rather than all talkgroups on the channel.
The enhancements support the following Scan mode:
• Mixed Vote Scan.
• Standard Conventional Scan.
• Priority Operation.
Up to 30 different talkgroups can be supported using conventional channels. A maximum of four
talkgroups can be supported when Vote Scan channels are being used.
Smart PTT is supported with this enhancement as Smart PTT prevents you from transmitting while
other users are on the channel.
NOTICE: User Selectable Talkgroups are not compatible with this Conventional Talkgroup
Enhancement.
1.4
What Your Dealer/System Administrator Can Tell You
If the radio is to be operated in extreme temperatures (less than -30 °C or more than +60 °C), check
with your system administrator for the correct radio settings.
You can consult your dealer or system administrator about the following:
• Is your radio programmed with any preset conventional channels?
• Which buttons have been programmed to access other features?
• What optional accessories may suit your needs?
NOTICE: Specifications may vary for different radio models. Contact your system administrator
for more information.
