FCC RF EXPOSURE COMPLIANCE REQUIREMENTS
FOR OCCUPATIONAL USE ONLY
The FCC has adopted a safety standard for human exposure to RF energy. Proper
operation of this radio under normal conditions results in user exposure to RF energy
below the Occupational Safety and Health Act and Federal Communication
Commission limits.
Mandatory Safety Instructions to Installers and Users:
This radio is NOT approved for use by the general population in an uncontrolled
environment. This radio is restricted to occupational use and work related operations
only. Radio operators must have the knowledge to control their exposure conditions
and the exposure conditions of bystanders and/or passengers to satisfy the lower
exposure limit allowed for General Population.
To comply with FCC RF exposure limits, DO NOT operate the transmitter of this mobile
radio when a person outside the vehicle is within 38 inches (1 meter) of the antenna for
mid-power radios, or 78 inches (2 meters) of the antenna for high power radios.
The antenna supplied by the manufacturer or radio dealer must be mounted at a
location such that during radio transmission, no person or persons can come closer
than the above indicated minimum safe distance to the antenna, i.e. 38 inches. To
comply with current FCC RF exposure limits, the antenna must be installed at or
exceeding the minimum safe distance stated above, and in accordance with the
requirements of the antenna manufacturer or supplier.
Vehicle Installation Instructions:
The antenna used for this transmitter must be mounted on the center of the roof ONLY
and must be installed in vehicle having the following characteristics in order to prevent
bystanders and passengers from being exposed to levels exceeding the limits for
General Population/Uncontrolled Exposure environment:
1. All passengers must be sitting under a solid metal roof.
2. Rooftop width must be at least 76 inches (183 centimeters) OR the edges of the
physical boundary of the vehicle must be at least 76 inches apart.
DO NOT operate the radio without the proper antenna installed. Do not substitute any
antenna for the one supplied or recommended by the manufacturer or radio dealer. The
antenna gain must not exceed 0 dBd. By not following the antenna recommendations
you may be exposing person(s) to excess radio frequency radiation. You may contact
your radio dealer or the manufacturer for further instructions.
DO NOT transmit more than 50% of total radio use time (50% duty cycle). Transmitting
for more than 50% of the time can cause FCC RF exposure compliance requirements
to be exceeded. This radio is transmitting whenever the TX icon is displayed on the
radio LCD. Pressing the PTT switch on the side of the microphone normally causes the
radio to transmit.
The preceding information is provided to make you aware of RF exposure and
how to ensure that this radio is operated within FCC RF exposure limits.
You, as the qualified end-user of this radio device must control the exposure conditions
of bystanders to ensure the minimum separation distance, stated above for satisfying
FCC RF exposure compliance, is maintained between the antenna and nearby
persons. Transmit only when all person(s) are at least the minimum distance from the
properly installed, externally mounted antenna.

Operation
Turning the Radio On and Off
Press and hold the power/volume knob for two seconds to turn
the radio on. The radio will perform a power-on test, which
includes lighting all display segments and may sound a single
beep when complete. Under certain circumstances, such as after
the radio has been reprogrammed, it may also display a check
code and sound a triple beep. Rotate the volume knob clockwise
to increase the volume.
Channel Selection
Rotate the channel/menu knob to select the channel. The radio
may be programmed to stop or Rollover when it reaches the
highest and lowest channels. Please consult your dealer or
communications coordinator regarding channels programmed in
your radio.
Group Selection
Your radio channels may be organized into channel groupings
that further sort and organize your channels. To select a different
group of channels, press the channel/menu knob twice, or until
the GRP is displayed, then rotate to the channel/menu knob until
the desired new group number or name is displayed. To exit,
press the channel/menu knob repeatedly until the first channel in
the new group is displayed.
Please consult your dealer or communications coordinator
regarding channel groups programmed in your radio.
Receiving Transmissions from Other Radios
Each channel of your radio may be programmed for carrier
squelch operation, CTCSS/DCS operation or 2-tone operation.
The following paragraphs describe these modes of operation.
Ask your dealer or communications coordinator if you have
questions on how your radio has been programmed to operate.

Titan™Mobile User’s Guide
14 ©2005, Midland Radio Corporation
Carrier Squelch Operation
A signal that matches the programmed receive frequency will be
heard if it is of sufficient strength to exceed the squelch
threshold. An on frequency signal exceeding the squelch
threshold level will be indicated by the BUSY icon.
CTCSS/DCS Operation
CTCSS or DCS signaling adds an additional condition to carrier
squelch operation. In addition to the signal having to exceed the
squelch threshold level, the received signal must also have the
correct CTCSS or DCS tone or code before the audio will be
passed to the speaker. CTCSS or DCS signaling allows multiple
users on the same frequency to hear only signals which have
their correct CTCSS tone or DCS code. An on frequency signal
without the correct CTCSS or DCS signal will be indicated by the
BUSY icon while no audio is heard.
CTCSS/DCS allows multiple users to share the same frequency.
However CTCSS/DCS is only useful to avoid disturbing other users with
messages not related to them. If more than one radio is transmitting at
the same time, this will cause interference. Do not transmit if the BUSY
icon is on. Wait until the channel is clear before transmitting.
2-tone Operation
2-tone signaling allows individual or group calls to be made to
your radio. On channels programmed for 2-tone decode
operation, you can press the channel/menu knob for two
seconds to mute all receive signals until the programmed 2-tone
signal has been decoded. After the programmed 2-tone signal is
decoded, the radio will beep, and subsequent receive audio will
be heard over the speaker. Press and hold the channel/menu
knob again to mute the radio until it receives a new call. Pressing
the MON button or PTT will disable the 2-tone muting function.
Consult your dealer or communications coordinator for further details on
how your radio has been programmed for 2-tone operation.

Titan™Mobile User’s Guide
©2005, Midland Radio Corporation 15
2-tone signaling allows users to receive only calls intended for them.
However, more than one radio transmitting at a time will still cause
interference. Do not transmit if the BUSY icon is on. Wait until the
channel is clear before transmitting.
Transmitting to Other Radios
Before transmitting, the FCC requires you monitor the channel to
make sure it is clear. Transmitting while someone else is
transmitting will create interference and disrupt both
conversations.
Follow these steps to transmit to other radios.
1. Monitor the channel by pressing the MON button. Channel activity is also
indicated by the BUSY icon.
2. If the channel is clear, press and hold the push to talk (PTT) switch on the
side of the microphone.
3. The TX icon will display while the radio is transmitting.
4. Hold the microphone approximately 2 inches from your mouth and speak
across the face of the microphone in a clear, normal voice.
5. Keep the PTT switch pressed until you have finished speaking.
6. Release the PTT switch to return to receive mode.
Do not shout! It will only create distortion.
Press PTT before you start talking and release PTT after you have
finished speaking.
Your radio doesn’t allow you to talk and receive simultaneously, so keep
your transmission short. When you are transmitting, other people can
not. Use common sense and do not occupy the channel too much.
The radio might be programmed with a timeout timer which will
automatically end your transmission after a preset time. In this case
release PTT and wait for a few seconds. The radio transmitter will be
enabled again after a few seconds. Ask your dealer or communications
coordinator for further details.
The radio might be programmed for busy channel lock out, which
automatically disables the transmitter if your channel is busy. In this
case wait until the channel is clear.

Titan™Mobile User’s Guide

Scanning Channels
If you have more than one channel programmed, your Titan
radio may be programmed to allow you to scan them. Press and
release the SCAN button to activate scan. The radio will begin
checking all channels in the scan list for activity. The SCAN icon
or PRI icon will be displayed while the radio is scanning. To turn
scan off, press and release the SCAN button again.
The scan mode and scan list are initially programmed by your
dealer or communications coordinator. If a priority scan mode
has been selected, the priority channel is checked for activity
more often than other channels in the scan list. The priority
channel will also be checked for activity while the radio is
receiving on a non-priority channel.
Once the receive signal ends, the radio may be programmed to
wait a period of time before resuming scan. When the Scan hold
after RX timer has expired, scanning will resume. There is also a
Scan hold after TX timer that will be started whenever the radio
has ceased transmitting on a channel. Your dealer or
communications coordinator will customize the scan options for
your particular situation; the following paragraphs detail the
available options. The scan mode depends on both the dealer
programmed Scan Selection and the user selection from the
menu functions as outlined in the table.

the other channels in the scan list. While scanning in Priority
scan mode, the radio will display “---“ and the PRI icon. If activity
is detected on a channel, the radio will pause scan and display
that channel. While stopped on a non-priority channel, the radio
will continue to check for activity on the priority channel(s). This
is called priority channel lookback, and the receive audio from
the non-priority channel will be briefly interrupted while priority
lookback occurs. While the radio is stopped on a non-priority
channel it may be deleted from the scan list by briefly pressing
the A/D button. This is the nuisance channel delete function. The
priority channel(s) can not be deleted from the scan list. To
resume scanning at the next channel in the scan list, without
deleting the channel, rotate the channel/menu knob clockwise.
In Priority scan mode the scan escape function may have been
enabled by your dealer or communications coordinator. To
temporarily suspend scan and switch to the last received
channel, press and release the AUX button. When finished
operating on the last received channel, press and release the
AUX button again to resume scan operation. The priority channel
selections will not be changed by the scan escape function.

priority channel. This is the primary difference between Public
Safety scan and Priority scan.
If activity is detected on a channel, the radio will pause scan and
display that channel. While stopped on a non-priority channel,
the radio will continue to check for activity on the priority
channel(s). This is called priority channel lookback, and the
receive audio from the non-priority channel will be briefly
interrupted while priority lookback occurs. While the radio is
stopped on a non-priority channel it may be deleted from the

and display the priority channel.

In Busy scan mode, when PTT is pressed while scanning, the
radio will transmit on the last received channel. If no last receive
channel has been established since scan was started, transmit
will occur on the scan start channel.
In Priority scan or Public Safety scan mode, the radio will always
transmit on the first priority channel while scan is turned on. The
first priority channel will also always be displayed while
transmitting.
If Priority Monitor mode has been activated, the radio will always
transmit on the displayed channel (whether operating channel or
priority channel(s)).
Editing Your Scan List
One of the features of your Titan mobile radio is the ability to add
channels and groups of channels to your scan list. Of course,
you may also delete channels from your scan list. These
changes are saved in radio EEPROM and are not temporary.
Depending on dealer programming the scan list edits may be
retained indefinitely or may be reset when scan or the radio are
turned off. Or, you may reset the scan list back to dealer
programming at any time by pressing the A/D button until the
second beep is heard.
The channels in your radio may be organized into groups and a
menu function allows you to select whether the scan will check
only channels in the current group or in all groups. Then within
each group, each individual channel may be selected for scan.
As you are editing the scan list, if the PRI icon or SCAN icon is
on, the channel is currently in the scan list. If the neither icon is
on that channel will not be scanned.
