WELCOME
Statistics show that about 80 percent of you will
not look at this manual until after you’ve already
taken the radio out of the box, tried to assemble it,
played around with it, and at some point came up
with something you didn’t understand.
IMPORTANT
So much
for this
box over
here.
To prevent
possible
damage, read all
instructions
before operating
this radio.
Even if you are reading this before operating
your radio, you’re still not planning on
reading all the instructions before you try to
work with your radio, are you?
Well, just be careful
because as our warranty
states, BK Radio isn’t
going to cover defects
caused by:
• Physical abuse or
misuse of the radio
• Neglect or accident
• Improper use or
installation of the radio
• Repair or alteration by
unauthorized personnel

BUILT-IN FEATURES
The BK Radio Aurora radio is based on a microprocessor core
that allows extra features and operational characteristics to be
programmed into your radio. Your dealer can help define the
best operational settings for your system and program them into
the radio.
AUDIO
Beeps, Boops, and Warbles
You can program your Aurora radio through the function menu
so that the radio can make five different sounds to notify you of
different radio functions:

• When you press a key on the keypad when you are in
normal or keypad programming mode
• When you use the channel knob to select a different
channel.
• When you press a valid key in the function menu (no
beep for invalid key presses)
• When your radio reaches the low battery threshold level
number 1. You will hear a single beep every 30 seconds
until you turn the radio off.
Boops
The boop is a lower tone of 780 Hz. You will hear a boop when
the radio encounters an illegal condition, including the
following:
• When you try to transmit on a busy channel that has an
incorrect Code Guard tone with the BCL option set
• When you try to transmit on a receive only channel
• When you try to tune a blank (unprogrammed) channel
• When you press an invalid key while in the function menu
Aurora User’s Manual
27
Boop-Beep
The boop-beep is a short duration tone of 780 Hz followed by a
short duration tone of 1560 Hz. You will hear a boop-beep:
• When you toggle a radio function ON with a softkey or
the three-position switch
• When you switch to scanning from manual mode
• When you switch to tone mode from monitor mode
Beep-Boop
The beep-boop sound is a short duration tone of 1560 Hz
followed by a short duration tone of 780 Hz. You hear the
beep-boop:
• When you toggle a radio function OFF with a softkey or
the three-position switch.
• When you switch to manual mode from scanning
• When you switch to monitor mode from tone mode
Warble
The warble sound is a continuous fixed-rate alternating of the
beep and boop tones. You hear the warble:
• When the radio receives the notification that the page
was received
• When the radio receives a man-down warning
Group pages and all-call pages have the longest alternating rate.
The radio page has a noticeably shorter alternating rate, and the
man-down notification has a very fast alternating warbling rate.
Audio Options
A dealer can program your Aurora radio for the following
options:
• Audible notifications at a fixed volume specified in a
percentage between 0% and 100% in 5% increments
• Variable volume setting that follows the volume knob
position
28
BK Radio
BATTERY-SAVER FEATURE
The battery-saver feature can be programmed by your dealer.
This function temporarily powers down the hardware when the
channel is not busy.
VOX OPERATION
Vox Operation is a special option that can be programmed on
or off at the factory. You can use the VOX operation feature
with an optional headset that can be connected to the radio via
the options connector.
If the your radio has the VOX option, you
can either toggle the VOX option ON/OFF
with a softkey/three-position switch
assigned to the VOX option, or on
advanced-model radios, you can use the
function menu.
If the options connector from the headset
is not attached, you cannot turn on VOX.
If the radio is in VOX mode and the
options connector is removed from the
radio, the radio automatically turns off
VOX mode.
To adjust the VOX trigger sensitivity
value:
1. Turn VOX ON by pressing and holding
the assigned softkey
2. Continue holding the softkey
3. Speak into the headset microphone at
the desired trigger volume level.
Aurora User’s Manual
29
Status Indicator
After 1 second, the radio will
automatically start adjusting the VOX
trigger sensitivity value. The radio
cycles through the 16 available trigger
values, starting at the least sensitive
value and incrementing to the most
sensitive value. Then the cycle wraps
around, and the radio repeats the cycle
as long as you keep pressing the
softkey.
4. When the status indicator LED on the
radio turns red, immediately release the
VOX softkey. The VOX trigger
sensitivity value has been reached.
CHANNEL SELECTOR
Channel
Selector
Knob
30
Use the channel selector knob to determine
which channel (from 1 to [up to] 16) is
tuned for receiving and transmitting when
the radio is in manual mode and no priority
channel operations are activated. See
priority channel operation (page 48) and
scanning mode (page 47) for more
information about the channel selector
knob when these features are activated.
BK Radio
HI/LOW TRANSMIT POWER
Each channel in the radio can be
individually programmed to always
transmit in low-power or high-power
mode, regardless of the position of the
radio’s switches (or the function menu
setting).
Once a radio channel is programmed for
low power, you will not be able to change
this setting to high power. If a channel has
been set to high power at the factory, the
dealer can change the power setting to a
softkey or the three-position switch. You
can also change the power setting from the
function menu if not assigned to the threeposition switch.
Low Power
High Power
Aurora User’s Manual
The Aurora radio has a set of display
transmit power icons [
]. One
illuminated icon indicates the channel will
transmit using low power [ ], and the
other illuminated icon indicates the channel
will transmit using high power [ ].
If the radio is in manual mode, these icons
are always illuminated to show either high
or low power for the selected channel. If
the radio is in scanning mode, the icons
only light when a scanned channel has an
active carrier that breaks the squelch of
your radio. If you select the low-power
setting, the low-power icon will be the only
transmit-power icon lit, regardless of the
transmit power programmed for that
channel.

receive Code Guard and bandwidth
parameters of that channel.
You can activate the talk-around feature
from the function menu if the function was
not assigned to the three-position switch.
If talk around is enabled, Code Guard and
paging ANIs are both temporarily removed
from the channel. When this happens, you
cannot see the radio paging icon [ ] in
the display of your radio.
MAN-DOWN SWITCH
The man-down feature is a factoryinstalled option. The switch is activated
when the radio is tilted. Then the radio
will start an emergency ANI sequence
transmission indicating the user is
“down.”
Aurora User’s Manual
37
EMERGENCY GROUP/CHANNEL
The emergency sequence is always
transmitted on the emergency group/
channel regardless of the current function
mode and channel. Once the emergency
sequence is started, and up to the time it is
acknowledged, the radio will stay on the
emergency group channel, although the
channel knob and group change function
are still active.
If you take the radio off the emergency
group/channel during an emergency
sequence, within the next 15-second
transmission interval, the radio will return
to the designated emergency group/
channel.
Activation
To activate the emergency ANI sequence
transmission:
Emergency Button
Man-down/
Emergency Icon
38
•
Press and hold the emergency button.
Your dealer can program the
emergency activation from 0.5 to 4.0
seconds in 0.5-second intervals, or
•
Tip the radio sideways. The factory
installed internal man-down tilt switch
will activate the signal.
Once activated, the man-down/emergency
icon [
] appears in the display in
advanced models. Your dealer can
program the length of time the radio can be
tilted before the man-down/emergency
code is transmitted.
BK Radio
Three seconds before starting the
man-down emergency sequence, you will
hear the man-down audible warning (a
fast-rate warbling lasting 3 seconds). If you
put the radio upright during the man-down
audible warning, the radio stops the
emergency sequence. If the radio stays
tilted for the duration of the man-down
audible warning, the emergency sequence
is immediately activated.
Enabling/Disabling
You can enable or disable the man-down
emergency mode either with the softkey/
three-position switch assigned to the
man-down function or with the function
menu. As long as the man-down switch is
factory installed, even if your dealer didn’t
program the emergency button to be used
for the emergency feature, the man-down
emergency feature remains available.
Transmit Speed and Frequency
The emergency feature, when activated,
transmits the radio’s emergency ANI up to
five times at 15-second intervals until the
radio emergency is acknowledged by the
dispatcher (by sending the radio’s ANI).
If the radio does not receive an emergency
acknowledgment, the emergency ANI
sequence is transmitted up to another five
times at 15-second intervals, except this
time the radio waits for an inactive
emergency channel condition before
transmitting.

radio in tone mode, and turned off when you
put the radio in monitor mode.
CODE GUARD MODE
The Aurora radio is capable of encoding or
decoding any of the currently used 50 CTCSS
tone guard signals, as well as any custom tone
from 67.0 Hz to 254.1 Hz within 1%
tolerance, or any of the 104 CDCSS Code
Guard signals. The radio is capable of
encoding one tone/code and decoding a
different tone/code on the same channel.
000.0000
Code Guard
Code Guard is active only when the radio is in
tone mode. While the radio is in tone mode
and the receive channels are programmed with
Code Guard, you can hear the message when
tuned to and receiving a frequency that has the
same Code Guard.
If the receive channel frequency is present, but
Code Guard is either not present or incorrect,
your radio stays quiet while receiving that
signal, even though the status LED is
illuminated to show channel activity.
42
BK Radio
Variable Guard
Advanced model radios have a variable
guard feature that lets you reassign the
Code Guard of one channel to another
channel within a group. You can use this
feature if your dealer programs your radio
to let you:
• Use the variable guard reassignment per
group option.
• Decide if you want the Code Guard
reassignment to apply to both the receive
and transmit channel frequencies or to
just the transmit frequency.
SCAN OPERATION
Scan mode applies to a single channel
group for a maximum of 16 channels in a
scan list. You can switch from manual to
scan mode from the function menu if
manual/scan or talk around is not already
assigned to the three-position switch.
Scan All Groups
Advanced Aurora radios also offer a scanall-groups option that scans through the
channels in all groups consecutively. You
can select this feature from the function
menu if scan all is not assigned to the
three-position switch.
Aurora User’s Manual
43
When you are scanning with both scan all
and priority enabled, the priority channel
you are sampling or transmitting on will
occur within the group that the radio was
in when you started the scan-all-groups
scanning.
P000.0000
When you change the radio from manual to
scan mode with scan all enabled and then
later you switch back from scan to manual
mode, the radio returns back to the group
it was in when you started scan mode.
Change the Scan List
Your dealer can program your radio to
give you the option of changing the scan
list channels yourself.
Scanning Options
Advanced Aurora radio models offer
several scanning options:
Scan Delay
The Aurora radio has a scan-delay time
parameter from 0 to 5 seconds in 0.5second increments. Your dealer can
program this time parameter on a per radio
basis.
The scan-delay time starts when the person
you are listening to stops talking. The
length of time your radio stays on that
scanned channel gives you time to transmit
or continue receiving on that channel
before the radio starts scanning again.
44
BK Radio
After the scan delay time, if the radio is not
in priority channel operation, the radio
transmits on the channel indicated by the
channel selector knob within the group that
is being scanned (see priority channel
operation for radio scanning operation
while priority mode is enabled on page 48).
Talkback Scan
Your radio has a talkback feature
(sometimes called talk around) that lets
you transmit on the channel you just
received a signal on under the following
conditions:
1. You stay on the same channel

You can activate talk around with a
computer-assigned softkey/three-position
switch or from the function menu if talk
around is not assigned to the three-position
switch.
If talkback scan is assigned to the
three-position switch , the manual/scan
feature is automatically added. Then with
the three-position switch, you can select
one of the following options:
• Perform in manual mode
• Perform in scan mode with talkback on
• Perform in scan mode with talkback off
(see priority channel operation for talkback
scan operation while priority mode is
enabled).
Aurora User’s Manual

Scan in Tone Mode
The Aurora radio is capable of scanning and
receiving channels with CTCSS tone guards
or CDCSS Code Guards. When you are on a
scanned channel with a carrier present, the
radio will try to decode the proper tone. If it
does, you will hear the message.
000.0000
If the channel has a carrier present, but the
tone is incorrect, the radio skips that channel
(removes it from the scan list) for a period of
3 seconds, and then adds it back to the scan
list.
Channels with radio paging codes assigned to
the receive frequency of the channel cannot
be part of a group’s scan list.
Scan in Monitor Mode
If you are listening to a signal on a scanned
channel, the radio will stay on that channel as
long as your radio keeps receiving the signal.
It does not matter if the channel has a Code
Guard or a radio paging code assigned to it
unless busy channel lockout is set for that
particular channel.
Transmit on Priority Channel
The Aurora radio has a feature that lets you
transmit on the priority channel while in scan
mode (see priority channel operation on
page 48).

PRIORITY MODES
The Aurora radio has five priority channel
modes of operation as shown in Table 6.
Your dealer can program these modes by
group, which lets the radio receive on any
channel while monitoring for messages on the
designated priority channel. The priority
sampling rate can be programmed by your

Priority Delay
Your dealer can set the priority delay time for
0 to 5 seconds in 0.5-second increments. This
time delay is the time from when you lose a
carrier for the priority channel and the time
the radio stays tuned to the receive frequency
of the priority channel. This is also the time
you have to transmit on the transmit
frequency of the priority channel.
Priority Receiving
Priority channel receive sampling only
occurs while the radio is not transmitting.
With priority mode enabled, the radio
samples either the programmed preset
priority channel (modes B or C), the
priority channel that you selected (modes
D or E), or the position of the channel
knob (mode A) (See Table 6).
Priority During Scan-All-Groups Scanning
The priority channel that is sampled and all
priority mode transmitting occurs within the
group the radio was in when Scan All Groups
scanning was initiated.
Table 6 summarizes channel selection,
whether scanning is in manual mode, whether
the talkback scan feature is enabled, and
whether a carrier is present at the time you
press the PTT switch. This information is
only for channel selection. Other settings,
such as busy-channel lockout during active
carriers, will still determine whether actual
transmission is possible.

RECEIVE MODE
Groups
A channel group can have up to 16 tunable
channels (both receive and transmit
frequencies). The basic Aurora radio has one
group, and the advanced Aurora (with
keyboard and display) has from 1 to 15
groups, depending on the computer
programming. Although the maximum
allowable channels per group is 16, any
number less than that, down to one channel,
can be programmable in a group.
For advanced model radios, you enter groupchange mode by following these three steps:
1. Put the radio into receive mode by not
transmitting.
Group 12
Channel Group 12
2. Press the [H]ome key while in receive

SELECTIVE CALLING
Radio Paging Code
Your dealer can program your radio to
decode 2-tone, 5-tone and DTMF ANIs, and
encode 5-tone and DTMF ANIs.
Receiving a Call
With the radio in receive mode, the squelch
will only open when it receives an ANI code
that is identical to its own ANI code.
• 2-Tone Decoding
The Aurora radio is capable of receiving
and decoding 2-tone-sequential paging.
Your dealer can program the tone
frequencies to cover Motorola 1+1, Reach
Two Tone, and GE Type 99 formats. The
dealer can also program tone duration and
intervals down to a zero interval. The radio
has the capability to decode RELM All Call
on either Tone A or Tone B. The 2-tone
page causes an audible warbling
notification.
• ANI Decoding (Receive ANI)—DTMF
or 5 Tone
The Aurora radio can have up to five
separate ANI page codes (each up to 10
digits) that can be assigned to a channel’s
receive frequency for general paging.
The paging codes are:
•
•
•
•
•
56
Unit ID
Group ID
All Call ID
Stun ID
Radio Check ID
BK Radio
When you receive a 2-tone, 5-tone (except
radio check and stun) or DTMF ANI
paging code, you can hear a warbling ring.
This ring sounds the same for 2-tone and
DTMF pages, but the group and all-call
pages each have a different warbling ring.
Your radio will ring for 3 seconds when
you receive a call. (See Receiving a Call,
page 56).
Sending a Call
The Aurora radio can encode the ANI
paging code for the Unit ID of a channel
group. The 5-tone or DTMF code is
assigned to the transmit frequency of a
channel. Your dealer can program your
radio for either leading PTT, trailing PTT,
or both edges of PTT when you transmit a
call. These PTT options are programmed
per channel for an internal time-out cycle.
The ANI is not transmitted during the
time-out period.
You can encode subaudible and audible
selective call signals simultaneously, but
the radio can only decode either subaudible
or audible selective calling signals on the
receive frequency of a channel.
If you are using an advanced Aurora radio,
you can generate call page dialing/ANI
sequences (DTMF or 5 Tone). These
options can be used for selective paging of
other radios. Advanced models can also
access and transmit paging and dialing
number sequences stored in the frequently
called numbers list in your radio.
Aurora User’s Manual
57
RADIO CHECK
The Aurora radio has a radio check feature
that is active whenever your radio is:
•
Programmed for receive-ANI paging
•
Tuned to a channel that has receiveANI assigned
•
Placed in tone mode
When radio check is active, if your radio
receives its radio check paging ANI, then it
transmits with its unit ID paging ANI. If
the transmit channel being transmitted is
programmed for transmit ANI, then the
unit ID goes out as specified by the
transmit ANI protocol (DTMF or 5 Tone).
If the transmit channel is not programmed
for transmit ANI, the unit ID is sent out
using the default paging parameter that
was programmed by your dealer.
DTMF DIALING
Advanced Aurora radios can generate
DTMF dialing sequences. To send DTMF
tones, refer back to DTMF Encoding,
page 36.)
Originating a Call
1. Key in a number (up to 10 digits).
2. If the channel is not busy, press PTT
to automatically transmit the connect
tone and ANI code of the radio.
58
BK Radio
REMINDER: The number does not
have to be keyed in each time you
make a call unless you want to change
the number or the radio has been
turned off since the last call.
3. Press the PTT switch to enable the
transmitter and the DTMF keypad.
4. While holding in the PTT switch, either
press the desired DTMF keys and/or
speak into the microphone of the radio.
5. After you finish talking, release the PTT
switch to listen to any reply.
Frequently Called Numbers and Call Paging
The Aurora radio can permanently store a list
of 10 frequently called numbers (FCNs).
Each number can have up to 10 digits. The
FCN list can be for DTMF or 5-Tone dialing
or paging code sequences.
You can also assign alpha labels (up to 10
characters each) to each FCN list number
from the keypad. In addition, your radio also
has separate memory to permanently store a
sequence of quick-call page numbers and
alpha labels of up to 10 characters.
When you transmit a call page or FCN
sequence, the ID of your radio goes with it.
This allows the Aurora radio that is receiving
the call to identify and display who paged it.
Aurora User’s Manual
59
Call page or FCN sequences are
transmitted after you
1. Select the CALL feature or one of the
FCNs from the function menu
2. Press the PTT switch
The page/FCN of your radio is transmitted
on the appropriate channel depending on
the manual/scan/priority mode of your
radio and the carrier activity when you
press the PTT switch. If the transmit
channel has Transmit-ANI assigned, the
leading/trailing/or both Transmit-ANIs are
sent as normal. The radio uses either the
DTMF or 5-Tone ANI assigned to the
channel. The call page/FCN goes out after
the leading ANI and before the trailing
ANI. Independent of whether DTMF or 5tone was assigned to the Transmit-ANI
channel, the call page/FCN goes out using
the DTMF or 5-Tone ANI you specified
when defining the call page or FCN.
Note: Call pages/FCNs using
DTMF digits “*” and “#” might
yield unpredictable results when
used within 5-Tone systems.
The Aurora radio can be factory enabled
so you can access radio paging from the
function menu. When enabled, the radio
paging operation is able to transmit the
FCN list of call pages.

RADIO PAGING
d Office
02
Channels with radio paging code signals are
indicated in the display with the radio page
icon [
] regardless of whether channels,
frequencies, or alphas are being displayed.
When the radio is receiving signals and the
radio page icon is illuminated, the receive
frequency has a paging code assigned. If the
radio is in monitor mode, the radio page icon
will not be illuminated while receiving.
When your radio is transmitting and the radio
page icon is illuminated, the transmit
frequency has a paging code assigned. This
code will go out on the leading edge, trailing
edge, or both edges of the PTT press.
FLEX MODE
The Aurora radio has two IF sections and
operates on either 12.5 kHz (narrow
bandwidth) or 30 kHz (wide bandwidth) for
the VHF model radio. The operating
bandwidth of the channel is a dealerprogrammable option that you can select on a
per-channel basis.
KEYPAD AND CHANNEL SELECTOR LOCK
You can lock the keypad on your radio so
any presses on the keypad are ignored by the
radio. While the keypad is locked, you can
see the lock icon [ ] in the display.
To lock or unlock the keypad, press and hold
[#] for 2 seconds.
Aurora User’s Manual
61
BUSY CHANNEL LOCKOUT
The Aurora radio has a Busy Channel
Lockout [BCL] feature that you can
use to program individual channels.
With the BCL feature, you can keep
anyone from hearing a channel unless
the correct Code Guard signal is
received.
With BCL set, the transmitter cannot
transmit until the channel is free of
activity. If the channel is active, the
transmitter cannot transmit until a
correct decode Code Guard is received.
If the BCL transmit criteria is not met,
you will hear a boop. When this
happens, release PTT and try
transmitting again.
If the BCL feature is set for a channel
and that channel has a Code Guard
assigned to it, the carrier must have a
tone. If a carrier is detected on that
channel and no tone is present, then the
radio will remain muted [no tone is the
wrong tone].
The BCL feature is activated
whenever you tune in to a channel that
has BCL assigned. If BCL mode is set
on the channel, the tone/monitor
feature will not override the BCL
function.

BATTERY POWER
Battery Saver
d Office
02
Low Battery Icon
Low-battery
indicator
The Aurora radio has a battery-saver
feature that your dealer can program on
a per radio basis. If enabled, the radio
performs the battery-saver function
when receiving channels without
receive-ANIs whenever in manual mode
and priority operation is turned off.
The battery-saver function cycles the
power to the RF, audio, and CPU
hardware, temporarily powering down
the hardware when the channel is not
busy. The Aurora radio has three lowbattery thresholds to let your radio run
as long as possible before shutting
down.
Low Battery
First Battery Threshold
Low Battery
The Aurora radio has a first battery
threshold level, which causes the radio
to transmit all channels using low
power, regardless of the transmit power
setting for that channel. You will see the
low-battery display icon [
] once the
battery voltage of the radio goes below
this threshold level.
At the first low-battery threshold, only
the low-power transmit icon [ ] is lit
regardless of the programmed transmit
Aurora User’s Manual
63
power of the channel or the power
setting you select. You will hear a
low-battery audio beep once every
30 seconds.
Once the radio shows the low-battery
icon, even if the battery voltage goes
above the threshold setting, the radio
will remain in the low-battery condition
until you replace the battery.
Second Battery Threshold
The Aurora radio has a second battery
threshold level. When the second
battery threshold is reached the status
LED will flash and the radio will not
transmit until the battery is removed and
reinstalled at a level above threshold
two.
Third Battery Threshold
The Aurora radio has a third battery
threshold level. When the third
threshold is reached, the radio suspends
all functions and in advanced models,
“Low Battery” is displayed. Lowbattery threshold three indicates the
radio battery has discharged to a level at
which you need to recharge the battery
immediately to prevent battery damage.
Turn the on/off switch into the OFF
position and charge the battery before
using the radio again.
64
BK Radio
RADIO POWER-UP
The Aurora radio performs a power-up
initialization and self test. The initialization
includes loading fixed factory and
computer-programmed settings, as well as
the configurations and modes you entered
into the radio before you turned it off.
During the initialization, the firmware
version number of the radio is written to
the first four bytes of the e2prom. After
you initialize the radio, the radio hardware
is tested to make sure the synthesizer locks
at the extremes of the radio’s tuning range.
ERROR MESSAGES
Orange status
indicator
Error 01
If the status indicator glows orange, your
radio has made an error. Advanced model
radios will also display “Error” with a
number. The radio will then try to return to
normal operation.
You can clear the error by changing the
channel knob position during the 5 seconds
the status indicator stays orange.
STUN
Your dealer can program your radio to
have a stun feature. This feature lets a
dispatcher disable normal radio functions
in case the radio is lost or stolen.
Aurora User’s Manual
65
The stun feature is active if the radio is:
•
Factory-enabled for audible ANI
paging
•
Tuned to a channel that is assigned a
receive ANI
•
Placed in tone mode
When the stun feature is active and the
current group’s stun code is received, the
radio transmits the unit ID of that channel.
This mutes the radio audio and disables
any further transmitting.
While a radio is stunned, if it receives the
current group’s stun code again, the radio
will cancel the stun mode restrictions and
return to normal radio operation.
