OPERATION
Installation and Programming
As the Base Tech II Base Repeater can be installed to opera te as either a Bas e St ation or as a R epeater,
some of the instructions in this docum ent may apply to one application only, some may apply in both
cases, while others may only appl y if the partic ular func tion has been enab led during programm ing of the
Base Tech II Base Repeater.
The Base Tech II Base Repeater must be programm ed before it will operate correctly. This should be
done by the equipm ent supplier or a qualif ied radio tradesman. T hey will require the Base Tech II Base
Repeater programming software to do this correctly.
7
Page 8
Base Tech II Base/Repeater Station Operator’s Manual
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 l ead to a suitable 13.8 Volt Regulated DC Power suppl y that has
sufficient capacity. (Ensure that the DC Polarity is correct).
o Connect the two antenna connectors to suitable antennas (ensure that the VSWR of the
antennas is correct).
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 clock wise (f rom the fu lly count er cloc kwise posit ion) slo wly unt il th e back ground
noise can no longer be hear d. It is wise to r ot ate the knob slightly further in t he clockwise direc ti on so that
variations in the background no ise level do not "break" the sq uelch setting and cause a nnoying squelch
noises to be heard from the speaker.
Select the Channel
•
Select the require d channel by pressing the C H key followed by the c hannel number k ey. The channel
number keys must be s el ec ted wit hin t wo seconds. For exam ple, [CH] + [0] + [1] to selec t C ha nne l 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 t o hear any radio traffic that occurs on cha nnel #1 on the Base Tech II Base
Repeater. It may be necessary to adjust the Volume setting to suit your listening requirements.
Transmitting
•
Depending on the legal requirements in your country, and the operating requirements within your
organization, it may be necessar y to announce your Call Sign. In addit ion, it will pr obabl y be ne cess ary to
announce the Call Sign of the party you are calling at the start of your transmission.
When transmitting, it is necessary to hold the microphon e about 3 inches from your m outh and speak
clearly into the front of the microphone.
It is also necessar y to press and hold the “Press To Talk” (PTT) bar on the side of the microphone while
speaking into the microphone.

Changing Channels
•
To change to another chann el, sim ply press th e [CH] k ey followed b y the num ber of the req uired cha nnel
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. T he cursor will blink at the
location of the channel number, and display the new numbers as they are entered.
It is also possible to ch ange cha nnels b y using the [ CH], [A] and [B] k eys inste ad 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 ad vance th e channe l to the next lo wer pr ogram med 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 sig nalin g c ap abil i ties . W e suggest that
you have your radio supplier conduct some training on the use of these capabilities prior to using them.
While it is possi ble to use these sig naling capabiliti es in both repeater mode, and in bas e station m ode,
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 comm only referred t o as “Selective Calling” (or Selc all) and usually comprises of a
series of 5 tones sequentiall y trans mitted or received in acc or da nc e with cer ta in inte r nat io nal 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 enco de up to six teen (16) t ones 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.
Entering a 5-Tone Encode Sequence
When switched "ON", the Base Tech II Base Repeater carries out i ts self -test routine, then waits read y to
11
Page 12
Base Tech II Base/Repeater Station Operator’s Manual
accept 5-Tone encode num bers. Accordingly, it is necessary to ent er the required 5-Tone digits directly
using the keypad, then pressing th e [#] k ey to transm it the 5-Tone sequence. (Up to sixteen digits c an be
entered).
If it is necessary to enter the "R" num ber sequence to activate the repeater, the [SHIFT] key must be
pressed before pressing the [#] key.
If a 5-Tone number is NO T displa yed in the LCD, and the [#] ke y is pressed, the n 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 m os t rec ent 5-Tone encode sequence and displ a y the sequ enc e in t he LCD
display. Continuing to press the [•] key will delete t he last digit of the s equenc e unt il al l digits are del eted.
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 av ai lab le if the "Attach Decode No " f iel d i n th e DT MF Enc od e Menu has bee n s et
to "ON".
Up to sixteen (16) DTMF digits can be encoded in one calling sequence.
DTMF Tone Entry
There are two methods of en tering DT MF to nes. T he spec ific to ne enc oding for m at is selec ted dur ing 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 autom atically selects the DTMF encoding for mat 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.
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 DT MF tones (up to sixteen tones, except "B" tone) and then transmit the total t one
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 cle ar before proceedin g, as it may take up to 5 seconds for the t ones to
be sent.
12
Page 13
Base Tech II Base/Repeater Station Operator’s Manual
For example, assum e that your decode number is 12345, and that you wish to enc ode number 12346.
You will input 12346, and then press the [#] key. The Base Tech II Base Repeater will encode
"12346B12345". The c alled ra dio will disp la y “12345” in their LCD indic ating the ca lling par ty's num ber is
"12345".
NOTE:
DTMF tone.
Pressing the [SHIFT] k ey and then the [#] will encode ONLY the encode number (and not the decode
number).
Redialing with DTMF
If, during the programm ing of the Base Tech II Base Repeater, the <Attach Deco de 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 programm ing of the Base Tech II Base Repeater, the <Attach Deco de No> field has been
set to "ON", the redialling function operates as follows:
Press [#] and the Base Tech II Base Repeater will redial th e last encoded DTMF num ber 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 rest ore the las t encode d DTMF num ber to the LCD displa y, provided the <Attach Dec ode
No> field has been set to "ON" during the program ming of the Bas e Tech II Base Repeater. First, confirm
that the LCD is NOT displaying a ny DTMF numbers . Then pres s [V] and the last enc oded DTMF number
will be displayed in the LCD display. It is possible to edit this number at this time b y pressing the [V] k ey
(which will erase the last number) or by pressing the required keys to add additional numbers.
The "B" tone is used as th e d elimiter in this encodi ng f ormat and therefore CAN NO T be us ed as a
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 program ming of the Base Tech II Base Repeater by setting the <DT MF Enco de> f ield
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 num ber. Second and s ubsequent 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).
Single Tone Encoding
•
The Base Tech II Base Repeater has t he abi li t y to e nc ode on e of s ix s ingle tone frequencies for 1, 2, 3, or
4 seconds. This function is enable d during program ming of the Bas e Tech II Base Rep eater by selec ting
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 fr equency ("xxxxHz") will be displayed in the tone area of the LCD displa y for
about 4 seconds until the Base Tech II Base Repeater reverts back to the normal signaling mode.
