Power On Indicator LED The Power ON Indicator LED will illuminate in green whenever the Power ON/OFF switch is in the "ON" position. 14. Liquid Crystal Display (LCD)) NOTE: When operating under extreme cold temperature conditions (below 0 deg C) allow a 30 minute warm up period for full display functionality. The LCD comprises of four (4) lines each of which is capable of displaying twenty-one (21) characters. The first line, under normal operating conditions, displays the strength of the signal being received on the selected channel as a bar graph. The second line displays the strength of the transmitting power as a bar graph. The third line displays the selected channel number (up to four characters) in the first five left hand character spaces, and displays the channel name (up to eight characters) in the next eight character spaces. Any combination of the following characters may be used in the channel name: 0-9, A-Z, a-z, / + - * # ! $ % ( ) = [ ] < > ? and space This area of the LCD is left blank when channel names are not used. The six character spaces on the right hand side of this line are used to display status symbols as follows: Symbol Status The monitor status. The key lock status. The tone encode status. The scan mode status. The high power transmit status. [SHIFT] key is depressed. On the left hand side of the fourth line, the type of tone signaling system selected by the user is displayed. For example, "5TON" indicates 5 Tone signaling while “DTMF” indicates Dual Tone Multi Frequency signaling. The right hand side of the fourth line is used to display data that the user enters (for example, 5 Tone calling sequences). These character spaces are also used by the Base Tech II Base Repeater to display messages and information directed to the user. 15.

![Base Tech II Base/Repeater Station Operator’s Manual 8 © Midland Radio Corporation Operation Installation and Programming As the Base Tech II Base Repeater can be installed to operate as either a Base Station or as a Repeater, some of the instructions in this document may apply to one application only, some may apply in both cases, while others may only apply if the particular function has been enabled during programming of the Base Tech II Base Repeater. The Base Tech II Base Repeater must be programmed before it will operate correctly. This should be done by the equipment supplier or a qualified radio technician. They will require the Base Tech II Base Repeater programming software (71-1480CD) and either 71-1303(A) Serial) or 91-1303B (USB) Programming cable to do this correctly. It is important that the Base Tech II Base Repeater be correctly installed at its working location by a qualified radio 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 sufficient capacity. (Ensure that the DC Polarity is correct). o For repeaters connect the two antenna connectors to suitable antennas (ensure that the VSWR of the antennas is correct). One connector for the base station o Insert the microphone into the microphone connector on the front panel. Basic Operation • Switch On Switch the Base Tech II Base Repeater "ON" by pressing the knob (12). Then check that the LED indicator (13) is illuminated. • Adjust the Volume Setting Rotate the Volume Knob (10) clockwise (from the fully counterclockwise position) until the audio level from the speaker is suitable. • Adjust the Squelch Setting Rotate the Squelch Knob clockwise (from the fully counter clockwise position) slowly until the background noise can no longer be heard. It is wise to rotate the knob slightly further in the clockwise direction so that variations in the background noise level do not "break" the squelch setting and cause annoying squelch noises to be heard from the speaker. • Select the Channel Select the required channel by pressing the CH key followed by the channel number key. The channel number keys must be selected within two seconds. For example, [CH] + [0] + [1] to select Channel 1. The LCD Display should now display CH01 and (if programmed with a channel label) the channel name: "CH01 NAME". • Receiving You should now be able to hear any radio traffic that occurs on channel #1 on the Base Tech II Base Repeater. It may be necessary to adjust the Volume setting to suit your listening requirements.](https://usermanual.wiki/Midland-Radio/710100B/User-Guide-1150452-Page-8.png)
![Base Tech II Base/Repeater Station Operator’s Manual 10 © Midland Radio Corporation Front Panel Operation This section describes most signaling and other advanced features that are available on the Base Tech II Base Repeater.

![Base Tech II Base/Repeater Station Operator’s Manual 12 © Midland Radio Corporation • Changing Channels To change to another channel, simply press the [CH] key followed by the number of the required channel within two 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 in the LCD will become blank as soon as the [CH] key is pressed. The cursor will blink at the location of the channel 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 channel numbers. 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 not programmed into the Base Tech II Base Repeater. Signaling The Base Tech II Base Repeater includes some very sophisticated signaling capabilities. We suggest that you have 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, many will 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 Tone signaling formats. The required signaling format(s) must be enabled when the Base Tech II Base Repeater is programmed. • 5-Tone Signaling Available Tones 5-Tone signaling is commonly referred to as “Selective Calling” (or Selcall) and usually comprises of a series of 5 tones sequentially transmitted or received in accordance with certain international standards. It is possible to use 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.](https://usermanual.wiki/Midland-Radio/710100B/User-Guide-1150452-Page-12.png)
![Base Tech II Base/Repeater Station Operator’s Manual 13 © Midland Radio Corporation Entering a 5-Tone Encode Sequence When switched "ON", the Base Tech II Base Repeater carries out its self-test routine, then waits ready to accept 5-Tone encode numbers. Accordingly, it is necessary to enter the required 5-Tone digits directly using the keypad, 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 pressed before pressing the [#] key. If a 5-Tone number is NOT displayed in the LCD, and the [#] key is pressed, then the Base Tech II Base Repeater will recall the most recent 5-Tone number and transmit it. Recalling the last encoded sequence Pressing the [] will recall the most recent 5-Tone encode sequence and display the sequence in the LCD display. Continuing to press the [] key will delete the last digit of the sequence until all digits are deleted. In practice, users will usually delete the last one or two digits before entering the new digits. • DTMF Signaling Available Tones The 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 Entry There are two methods of entering DTMF tones. The specific tone encoding format is selected during the programming of the Base Tech II Base Repeater in the <Main Menu><Encode Set><DTMF Encode><Attach Decode No.> field. Attach Decode No. "OFF" format Pressing the PTT lever first automatically selects the DTMF encoding format and allows direct entry of DTMF tones. Hold the PTT lever on the microphone while pressing the required DTMF tones. The tones will be transmitted as the keys are being pressed.](https://usermanual.wiki/Midland-Radio/710100B/User-Guide-1150452-Page-13.png)
![Base Tech II Base/Repeater Station Operator’s Manual 14 © Midland Radio Corporation Attach Decode No. "ON" format Attach Decode No. "ON" automatically encodes the user’s DTMF decode number after the encode number. This can 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 continuous sequence 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 will input 12346, and then press the [#] key. The Base Tech II Base Repeater will encode "12346B12345". The called 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 DTMF tone. Pressing the [SHIFT] key and then the [#] will encode ONLY the encode number (and not the decode number). Redialing with DTMF If, 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 redialing function operates as follows: Press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number with the Base Tech II Base Repeater's programmed decode number. Press [SHIFT], then press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number without the Base Tech II Base Repeater's programmed decode number. Restoring the last DTMF number to the LCD Display It 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 the LCD is NOT displaying any DTMF numbers. Then press [V] and the last encoded DTMF number will be displayed in the LCD display. It is possible to edit this number at this time by pressing the [V] key (which will erase the last number) or by pressing the required keys to add additional numbers. Encoding DTMF numbers with the 5-Tone system enabled It is possible to enter DTMF numbers even with the 5-Tone system enabled. This function must be enabled during the programming of the Base Tech II Base Repeater by setting the <DTMF Encode> field in the <5Tone Encode Menu> to "ENABLE". To enter a DTMF number (with 5-Tone signaling enabled), the user must press the PTT lever while entering the first DTMF number. Second and subsequent numbers do NOT require the PTT lever to be pressed, provided all numbers are entered within a few seconds (before the display reverts to 5-Tone mode and displays "5TON" in the LCD display).](https://usermanual.wiki/Midland-Radio/710100B/User-Guide-1150452-Page-14.png)
![Base Tech II Base/Repeater Station Operator’s Manual 15 © Midland Radio Corporation • Single Tone Encoding The Base Tech II Base Repeater has the ability to encode one of six single tone frequencies for 1, 2, 3, or 4 seconds.
