Base Tech II Base/Repeater Station Operator’s Manual
INTRODUCTION
Description
The Base Tech II Base Repeater represents a technological advancement over previous mo dels. The Base Tech II Base Repeater is comprised of separate modules all housed within one 2RU equipment cabinet. The receiver, tran smitter , and PA unit are each enclosed within their own die-cast hou sing. Each one is then mounted directly on the large upper heatsink. A microprocessor-controlled interface module controls the channel selection, LCD Display, timers, interfaces, and signaling features.
The RF power output is 25 — 50/ 60 watts or 50 — 100/ 110 watts on a continuous duty basis. The CTCSS module supports all EIA tones. All tones and different encode and d ecode tones can be set on a per channel basis during radio programming.
Attention
The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 6 meters from all persons during normal operation. The peak conducted output power at each antenna terminal must not exceed 250 Watts and the peak radiated output power must not exceed 1000 Watts EIPR. Users and installers must ensure that FCC requirements for satisfying RF exposure compliance are met. (See FCC Rules Part 1, Sections 1307 and 1310)

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 a s a ba r 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 sym bols 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 sign aling 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 disp lay messages and information directed to the user.

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 program ming 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 Rep eater 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 co rrectly inst alled 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 th at the LED indicato r (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 V olume 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 necessary to announce your Call Sign. In addition, it will probably be necessary 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 microphone about 3 inches from your mouth and speak clearly into 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 while speaking into the microphone.
