This should be done bythe equipment supplier or a qualified radio tradesman. They will require the Base Tech II Base Repeaterprogramming software to do this correctly.It is important that the Base Tech II Base Repeater be correctly installed at its working location by a qualifiedradio technician.As a minimum, it is necessary to:o  Connect the DC Input power lead to a suitable 13.8 Volt Regulated DC Power supply that has sufficientcapacity. (Ensure that the DC Polarity is correct).o  Connect the two antenna connectors to suitable antennas (ensure that the VSWR of the antennas iscorrect).o  Insert the microphone into the microphone connector on the front panel.
Base Tech II Base/Repeater Station Operator’s Manual8Basic Operation• Switch OnSwitch the Base Tech II Base Repeater "ON" by pressing the knob (12). Then check that the LED indicator (13)is illuminated.• Adjust the Volume SettingRotate the Volume Knob (10) clockwise (from the fully counterclockwise position) until the audio level from thespeaker is suitable.• Adjust the Squelch SettingRotate the Squelch Knob clockwise (from the fully counter clockwise position) slowly until the background noisecan no longer be heard. It is wise to rotate the knob slightly further in the clockwise direction so that variations inthe background noise level do not "break" the squelch setting and cause annoying squelch noises to be heardfrom the speaker.• Select the ChannelSelect the required channel by pressing the CH key followed by the channel number key. The channel numberkeys must be selected within two seconds. For example, [CH] + [0] + [1] to select Channel 1. The LCD Displayshould now display CH01 and (if programmed with a channel label) the channel name: "CH01 NAME".• ReceivingYou should now be able to hear any radio traffic that occurs on channel #1 on the Base Tech II Base Repeater. Itmay be necessary to adjust the Volume setting to suit your listening requirements.• TransmittingDepending on the legal requirements in your country, and the operating requirements within your organization, itmay be necessary to announce your Call Sign. In addition, it will probably be necessary to announce the CallSign of the party you are calling at the start of your transmission.When transmitting, it is necessary to hold the microphone about 3 inches from your mouth and speak clearlyinto the front of the microphone.It is also necessary to press and hold the “Press To Talk” (PTT) bar on the side of the microphone whilespeaking into the microphone.
Base Tech II Base/Repeater Station Operator’s Manual9Front Panel OperationThis section describes most signaling and other advanced features that are available on the Base Tech II BaseRepeater. The availability of some features is dependent on the programming of the transceiver and installedoptions. You may find it worthwhile to discuss these features in detail with your radio supplier to obtain a fullunderstanding of their benefits.• Keypad OperationThe Keypad is the interface between the user and the Base Tech II Base Repeater. It is used to enable ordisable various functions and to enter the required data for signaling purposes.The word (5-Tone) or (DTMF) shown after the described feature indicates that the described feature applies tothe particular signaling format.The following keys are used for the purposes described:[0] - [9] Entering new channel numbersEntering the "KILL" passwordEntering signaling encoding numbers (5-Tone) (DTMF)Entering DTMF numbers (DTMF)[A] Advancing the Base Tech II Base Repeater to the next higher channelEntering the signaling "A" tone (5-Tone) (DTMF)Encodes the "A" Tone (DTMF)[B] Advancing the Base Tech II Base Repeater to the next lower channelEntering the signaling "B" tone (5-Tone) (DTMF)Encodes the "B" Tone (DTMF)[C] Entering the signaling "C" tone (5-Tone) (DTMF)Encodes the "C" Tone (DTMF)[D] Entering the signaling "D" tone (5-Tone) (DTMF)Encodes the "D" Tone (DTMF)[*] Displays the previously entered encode numbers (5-Tone) (DTMF)Encodes the "*" -Tone (DTMF)[#] Encodes the signaling numbers that are displayed in the LCD display (5-Tone) (DTMF)Encodes the "#"-Tone (DTMF)[CH] Used with two channel numbers [0] - [9] to change the active channel on the Base Tech IIBase Repeater. E.g.

Base Tech II Base/Repeater Station Operator’s Manual11• Changing ChannelsTo change to another channel, simply press the [CH] key followed by the number of the required channel withintwo seconds.For example:  To select Channel 8, press [CH] [0] [8]To select Channel 99, press [CH] [9] [9]Note that it is always necessary to enter two digits for the Channel Number. The channel # location displayed inthe LCD will become blank as soon as the [CH] key is pressed. The cursor will blink at the location of thechannel number, and display the new numbers as they are entered.It is also possible to change channels by using the [CH], [A] and [B] keys instead of entering the channelnumbers. Pressing the[CH] then the [A] key will advance the channel to the next higher programmed channel,while pressing [B] will advance the channel to the next lower programmed channel.Note that this action will ignore channels that have not been programmed into the Base Tech II Base Repeater.Accordingly, the LCD display may appear to advance more than one channel if the missed channel is notprogrammed into the Base Tech II Base Repeater.SignalingThe Base Tech II Base Repeater includes some very sophisticated signaling capabilities. We suggest that youhave your radio supplier conduct some training on the use of these capabilities prior to using them.While it is possible to use these signaling capabilities in both repeater mode, and in base station mode, manywill only be useful in practice when the Base Tech II Base Repeater is used in base station configuration.The Base Tech II Base Repeater supports the 5-Tone sequential, and/or the DTMF, and the Single Tonesignaling formats. The required signaling format(s) must be enabled when the Base Tech II Base Repeater isprogrammed.• 5-Tone SignalingAvailable Tones5-Tone signaling is commonly referred to as “Selective Calling” (or Selcall) and usually comprises of a series of5 tones sequentially transmitted or received in accordance with certain international standards. It is possible touse longer sequences to enhance the signaling capabilities and to provide additional functions.Accordingly, the Base Tech II Base Repeater will encode up to sixteen (16) tones and decode up to eight (8)tones.These tones can be any of the following letter/number combinations:[0] - [9], and [A] - [D]The most recently entered tone can be recalled and deleted by pressing the [*] key repeatedly.
Base Tech II Base/Repeater Station Operator’s Manual12Entering a 5-Tone Encode SequenceWhen switched "ON", the Base Tech II Base Repeater carries out its self-test routine, then waits ready to accept5-Tone encode numbers. Accordingly, it is necessary to enter the required 5-Tone digits directly using thekeypad, then pressing the [#] key to transmit the 5-Tone sequence. (Up to sixteen digits can be entered).If it is necessary to enter the "R" number sequence to activate the repeater, the [SHIFT] key must be pressedbefore pressing the [#] key.If a 5-Tone number is NOT displayed in the LCD, and the [#] key is pressed, then the Base Tech II BaseRepeater will recall the most recent 5-Tone number and transmit it.Recalling the last encoded sequencePressing the [*] will recall the most recent 5-Tone encode sequence and display the sequence in the LCDdisplay. Continuing to press the [*] key will delete the last digit of the sequence until all digits are deleted. Inpractice, users will usually delete the last one or two digits before entering the new digits.• DTMF SignalingAvailable TonesThe following DTMF tones can be used in any number/letter combination:[0] - [9], [A] - [D], [*], and [#]NOTE: Tone [B] is NOT available if the "Attach Decode No" field in the DTMF Encode Menu has been set to"ON".Up to sixteen (16) DTMF digits can be encoded in one calling sequence.DTMF Tone EntryThere are two methods of entering DTMF tones. The specific tone encoding format is selected during theprogramming of the Base Tech II Base Repeater in the <Main Menu><Encode Set><DTMF Encode><AttachDecode No.> field.Attach Decode No. "OFF" formatPressing the PTT lever first automatically selects the DTMF encoding format and allows direct entry of DTMFtones.Hold the PTT lever on the microphone while pressing the required DTMF tones. The tones will be transmitted asthe keys are being pressed.
Base Tech II Base/Repeater Station Operator’s Manual13Attach Decode No. "ON" formatAttach Decode No. "ON" automatically encodes the user’s DTMF decode number after the encode number. Thiscan be used for any purpose.Enter the required DTMF tones (up to sixteen tones, except "B" tone) and then transmit the total tone sequence(including the users decode number) by pressing the [#] key. All tones will be transmitted in one continuoussequence after pressing the [#] key.Pressing the [*] key will delete the last number entered.Always confirm that the LCD is clear before proceeding, as it may take up to 5 seconds for the tones to be sent.For example, assume that your decode number is 12345, and that you wish to encode number 12346. You willinput 12346, and then press the [#] key. The Base Tech II Base Repeater will encode "12346B12345". Thecalled radio will display “12345” in their LCD indicating the calling party's number is "12345".NOTE: The "B" tone is used as the delimiter in this encoding format and therefore CANNOT be used as a DTMFtone.Pressing the [SHIFT] key and then the [#] will encode ONLY the encode number (and not the decode number).Redialing with DTMFIf, during the programming of the Base Tech II Base Repeater, the <Attach Decode No> field has been set to"OFF", the redialing function operates as follows:Press [SHIFT], then press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number.If, during the programming of the Base Tech II Base Repeater, the <Attach Decode No> field has been set to"ON", the redialling function operates as follows:Press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number with the Base Tech IIBase Repeater's programmed decode number.Press [SHIFT], then press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF numberwithout the Base Tech II Base Repeater's programmed decode number.Restoring the last DTMF number to the LCD DisplayIt is possible to restore the last encoded DTMF number to the LCD display, provided the <Attach Decode No>field has been set to "ON" during the programming of the Base Tech II Base Repeater. First, confirm that theLCD is NOT displaying any DTMF numbers. Then press [V] and the last encoded DTMF number will bedisplayed in the LCD display. It is possible to edit this number at this time by pressing the [V] key (which willerase the last number) or by pressing the required keys to add additional numbers.Encoding DTMF numbers with the 5-Tone system enabledIt is possible to enter DTMF numbers even with the 5-Tone system enabled. This function must be enabledduring the programming of the Base Tech II Base Repeater by setting the <DTMF Encode> field in the <5ToneEncode Menu> to "ENABLE".To enter a DTMF number (with 5-Tone signaling enabled), the user must press the PTT lever while entering thefirst DTMF number. Second and subsequent numbers do NOT require the PTT lever to be pressed, provided allnumbers are entered within a few seconds (before the display reverts to 5-Tone mode and displays "5TON" inthe LCD display).
Base Tech II Base/Repeater Station Operator’s Manual14• Single Tone EncodingThe Base Tech II Base Repeater has the ability to encode one of six single tone frequencies for 1, 2, 3, or 4seconds. This function is enabled during programming of the Base Tech II Base Repeater by selecting the<Single Tone ON> field in the <Encode Menu>, and setting the encode period.Press the [SHIFT] and the [4] keys to put the Base Tech II Base Repeater into Single Tone Encoding mode. "S1"and the tone frequency ("xxxxHz") will be displayed in the tone area of the LCD display for about 4 seconds untilthe Base Tech II Base Repeater reverts back to the normal signaling mode.While the Base Tech II Base Repeater is in Single Tone Encoding mode, it is possible to advance to the nexttone frequency by pressing the [A] key, or to return to the previous tone by pressing the [B] key.Pressing the [#] key will encode the displayed tone (for the programmed time period). It also automatically exitsthe Single Tone Encoding mode and returns the Base Tech II Base Repeater to the normal signaling mode.ScanningThe Base Tech II Base Repeater is supplied with two scanning modes. These are All Channel Scan mode inwhich the Base Tech II Base Repeater will scan all channels that are programmed into the Base Tech II BaseRepeater, and the Program Channel Scan mode in which the Base Tech II Base Repeater will scan only thechannels that have been designated during the programming of the Base Tech II Base Repeater.
