The Volume Control is used to set the audio output level from the loudspeaker. Rotate this knob clockwise to increase the audio level, or counter-clockwise to reduce the audio level.
11. Squelch Control*
The Squelch Contro l is used to set the squelch threshold. Select a channel that is not being used and slowly rotate this knob clockwise until the annoying background noise ceases. It may be desirable to rotate this knob clockwise, slightly past the squelch threshold, to compensate for varying background noise levels.
12. Power ON/OFF Switch
The Power ON/OFF Switch is use d to switch the Base Tech II Base R epeater "ON" or "OFF". Pr ess this knob to switch the Bas e Tech II Base Repeater "O N". Press this knob again to switch the Base Tech II Base Repeater "OFF". This knob is slightly more depressed when in the "ON" position.

14. Liquid Crystal Display (LCD) (not used on Single Channel Models)
The LCD comprises of four (4) lines each of whic h is capable of displa ying twenty-one (21) characters. The first line, und er norm al oper ating c ondit ions , dis plays th e str ength of the sig nal being r eceive d o n th e selected channel as a bar graph. T he sec ond line d ispla ys the s trength of the trans m itting po wer as a bar graph. The third line dis p lays the selected chann el number (up to four c har ac ter s) in t he f ir s t f ive lef t ha nd 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 us er enters (for example, 5 Tone calling sequences) . These charac ter spaces ar e also used b y the Base Tech II Base Repeater to displa y messages and information directed to the user.

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.

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.
