BK Radio 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: Beeps The beep is a tone of 1560 Hz. You will hear the beep: • 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. 31 FUNCTION MENU Any functions not assigned to a side button or the three-position toggle switch can be enabled/disabled with or on the keypad.

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. Aurora User’s Manual 39 OPERATING MODES MANUAL MODE Channel Selector Knob The Aurora radio can operate in manual mode, which ties the receive and transmit frequencies to the channel you select with the channel selection knob (within the currently selected channel group). For advanced model radios, you can select manual mode from the function menu if manual/scan or talk around is not assigned to the three-position switch. 000.0000 000.0000 12 Reassigned channel number 000.0000 For advanced radios in tone mode [ ], your radio displays the receive and transmit frequencies that indicate the reassigned Code Guard. You can see the number of the reassigned channel in the right-most part of the radio display. Receive and transmit frequencies also indicate the assigned radio paging code (audible signals) by lighting the paging icon [ ] in the display when the radio is tuned to that frequency. When the radio is in monitor mode, the paging code icon is not lit. 40 BK Radio For advanced radios in manual mode, you can use the keypad for the following six functions: 1. Reassign the variable guard. Press number keys [0] through [9] 2. Enter group change mode: Press the [H]ome key. Then press or to change the group number. 3. Add or delete channels from the scan list. Press the [E]nter key. R114.8 T107.2 Code Guard Assignment Channel 1 Keypad Locked 4. Review a channel’s Code Guard assignment. Press and hold the [*] key. 5. Enter the function menu. Press either or . 6. Lock or unlock the keypad. Press and hold the [#] key for 1 second. If priority channel operation is activated in manual mode, the radio will monitor, not only the selected manual channel, but also the group priority channel at the priority sampling rate. Tone/Monitor Toggle From the function menu, you can toggle tone mode and monitor mode: 1. Tone mode—Listening to channels only if the correct Code Guard or radio paging code programmed for that channel is present. 2. Monitor mode—Listening to channels regardless of the channel Code Guard or radio paging code programming. Aurora User’s Manual 41 Channels assigned with receive selective calling signals and set for busy-channel lockout cannot be monitored if the radio is in monitor mode. Channels that are programmed with no tone are not affected if the radio is placed in either monitor mode or tone mode. You will hear a beep/boop sound when toggling between tone and monitor modes. For advanced model radios, the tone mode icon [ ] is illuminated when you put the 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 . . ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... 2. You keep the radio in scan mode 3. You press the PTT switch while you are receiving the channel or during the scan-delay period PTT 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 45 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). 46 BK Radio Channel Scan Delete/Add Squelch Knob With the Aurora radio, you can delete and add channels to the scan list in each group if this feature is programmed in your radio. To add or delete a channel from the scan list: 1. Use the function menu to put the radio in scan mode on an active receive carrier. 2. Tune your radio to the frequency of a receive channel frequency, or open the squelch to the channel being added or deleted. 3. Press [E]nter to toggle between deleting or adding a channel to the scan list. If the channel is already in the scan list, pressing [E]nter will delete it from the scan list, and if the channel is not on the scan list, pressing [E]nter will add the channel to the scan list. d 000.0000 Channel deleted from scan list P 000.0000 Priority channel deleted from scan list Aurora User’s Manual When the radio is on a channel in manual mode (or scan mode on an active channel) and you have deleted the channel from the scan list, the display will indicate that this channel is not on the scan list by displaying “d” in the first alpha character position of the display. If the channel is the group’s priority channel, then a “p” is shown instead of “d” for a deleted channel. 47 Priority Scan Priority Scan with Code Guard Priority scan can be used along with Code Guard when: Code Guard . . ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... • You move the three-position switch into position 1, which displays the channel frequency. • You press the top, gray button on the side of the radio to toggle to the Code Guard position Priority • You press the middle button on the side of the radio to toggle to the priority position • The priority channel is programmed with Code Guard If a message is received on the priority channel, the radio receiver locks on to the priority channel for the duration of the signal. You will only hear the message if the proper Code Guard value is received. The radio resumes scanning after the message ends and the scan delay time expires. 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 dealer for between 0.25 and 2.50 seconds, regardless of activity on any other channel. 48 BK Radio Orange Status Indicator P 000.0000 Priority Channel When you turn on priority mode by pressing the middle button on the side of the radio, you will see the status indicator flash orange, which indicates an actual priority channel sampling. For advanced model radios, the priority channel of a group is indicated by a “P” [a small “p” when deleted from the scan list] on the left side of the radio display. P 000.0000 Priority Channel deleted from scan list Table 6. Priority Modes Aurora User’s Manual 49 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. 50 BK Radio 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 mode. The display will show “Group XX” where XX is the current channel group. Note: If the radio is scanning when you enter group-change mode, the radio will be temporarily disabled until you exit group-change mode. 3. Once the radio is in group change mode, the only active front keypad keys are: Aurora User’s Manual • [ ] Changes the radio to the next highest group, or if the radio is already at the highest group, it wraps around to Group 1 • [ ] Changes the radio to the next lowest group, or if the radio is already at group 1, the group wraps around to the highest channel group 51 • [E]nter Exits the group change mode • [H]ome Displays the alpha label of the group The radio will remain in group change mode until you exit by pressing the [E]nter key. DISPLAY MODES You can select a display mode either with a softkey/three-position switch programmed to display functions, or with the function menu. If you use a softkey, each key you press selects the next display mode. The radio will keep cycling through the channel, frequency, and alpha modes. If you use the three-position switch (factory default), • Position 1 is channel frequency • Position 2 is channel label • Position 3 is group number, channel number, and bandwidth mode TUNING RANGE The tuning range of Aurora’s basic and advanced radios cover the VHF band from 136.0000 MHz to 174.0000 MHz. 52 BK Radio FREQUENCY DISPLAY MODE If you own an Aurora radio with a display, you have the option of displaying the current group/channel frequency information as follows: P 000.0000 Priority Channel P 00000000 Character Positions 2–9 P 139 . 650 00 Character Positions 13–14 P 139. 6500 02 Aurora User’s Manual • Priority channel/deleted channel specifier (first display character position) P = Group priority channel Select in scanlist p = Group priority channel Delete from scanlist “ ” = Not group priority channel Select in scanlist d = Not group priority channel Delete from scanlist • Current Group/Channel frequency in megahertz P00000000 = character positions 2–9 PG01 CH01 = group/channel • Variable Code Guard reassignment ZZ = [display character positions 13–14] ZZ = reassigned Code Guard channel 1–16 For example, a radio is in group 8 and tuned to channel 12 at a frequency of 139.6500 MHz. Channel 12 is the priority channel for group 8 and currently in the scan list. You reassign the Code Guard of channel 12 to the Code Guard of channel 2 by pressing the channel numbers on the keypad. The display of the radio will then look like the display to the left. 53 ALPHA DISPLAY MODE If you have an Aurora radio with a display, you can select how the radio shows you the current group/channel alphanumeric information: d 000.0000 Deleted Channel d A8CD5FG6J Character Positions 2–11 • Priority channel/deleted channel specifier (first display character position) P = Group priority channel Select in scanlist p = Group priority channel Delete from scanlist “ ” = Not group priority channel Select in scanlist d = Not group priority channel Delete from scanlist • Current Group/Channel alphanumeric YYYYYYYYY = display character position 2–11 YYYYYYYYYY = group/channel alphanumeric, up to 10 characters d 139 . 650 00 Character Positions 13–14 d Office 54 02 • Variable Guard reassignment ZZ = display character position 13–14 ZZ = reassigned Code Guard channel, between 1 and 16 For example, the display to the left shows a radio in group 8 and tuned to channel 12 whose channel label is Office. Channel 12 is not the priority channel of the group and has been deleted from the scan list. You reassign the Code Guard of channel 12 to the Code Guard assigned to channel 2. The display will then look like the bottom display to the left. BK Radio CHANNEL DISPLAY MODE If you have an Aurora radio with a display, you can select how the radio displays the current channel information: • Priority channel/deleted channel specifier (first display character position) P 000.0000 Priority Channel deleted from scan list P = Group priority channel Select in scanlist p = Group priority channel Delete from scanlist “ ” = Not group priority channel Select in scanlist d = Not group priority channel Delete from scanlist P G08 CH12 Group Number Channel Number P G08 CH12n Narrow Band P G08 CH12n01 Reassigned Code Guard Channel P G08 CH 12 w02 Aurora User’s Manual • Current Group Number GXX = display character position 2–4 XX = group number 1 through 15 • Current Channel Number CHYY = display character position 6–9 YY = channel number 1 through 16 • Channel Spacing n = narrow band w = wide band • Variable Guard reassignment ZZ = display character position 13–14 ZZ = reassigned Code Guard channel, between 1 and 16 For example, the display to the left shows group 8 is tuned to channel 12 (which happens to be the group’s priority channel, which is currently deleted from the scan list). The Code Guard has been reassigned to the Code Guard on channel 2, and the radio is tuned using wide band channel spacings. 55 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. 60 BK Radio 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. 62 BK Radio 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. 66 BK Radio AURORA PROGRAMMED SWITCH SETTINGS Side Switch Settings (Factory Setting) Switch A _____________(Code Guard; Tone/Monitor) Switch B _____________(Priority) Switch C _____________(Hi/Low Power) 3-Position Toggle Switch 1 ______________(Channel Frequency) 2 ______________(Channel Label) 3 ______________(Group, Channel, BW) Emergency Switch Setting ________________(Scan) Group Number ______ Receive Chan Frequency CG Group Label __________________ Transmit Frequency CG Label Band 10 11 12 13 14 15 16 Aurora User’s Manual 67 PROGRAMMED SETTINGS FOR YOUR RADIO Group Number ______ Receive Chan Frequency CG Group Label __________________ Transmit Frequency CG Label Band 10 11 12 13 14 15 16 68 BK Radio TROUBLESHOOTING GUIDE NOTE: Please perform the simple checks indicated for improper operation before returning the radio for service.
