1) LCD Display LCD display consists of 4 x 20 characters as shown. Line 1 : Incoming RSSI with 10 steps Line 2: Output power levels with 10 steps Line 3: Left 4 letters show Channel Numbers. Middle 8 letters show channel name (if not programmed, shows blank). Right 4 letters show status of the radio. 1/ RX mode : M= Mix, both analog and digital can be received D= Only digital can be received.
3) Key controls a/ Key entry without SHIFT key 0-9 : channel numbers and individual call address (target address) A: P-25 calls (Group call, All call, Individual call) B: The beginning and the end of individual call number C: No function D= P-25 mode (analog or digital) *= Cancel channel number, individual number #= Ending channel number, individual number CH= Channel number entry, depress CH, then 0-9 for channels F(Scan)= No function MON= monitor ON or OFF ' Rotary knob: Volume, Squelch, Back Light Dimmer
4) Programming Base Tech III can be programmed through PC at anytime when RX mode. Programming is not possible while Base Tech III in key entry. When programming is started, the LCD indicates as shown. Figure-1 shows Data from radio to PC, Figure-2 shows Data from PC to radio. If the program software is not communicating properly, the radio will re-write again and again (endless). When this happens, keep depressing SHIFT and switch on the radio. Then the radio will recover.
5) Volume control Push rotary knob, and then rotating the knob. Volume level varies from VOLO to VOL-34. Figure 4 shows VOL-12 level RX TX ========== ========== C001 Channel GP VOL - 1 2 Figure 4. 6) Squelch control Push rotary knob to select Squelch. Squelch level varies from SQL-l to SQL-l5. Figure-5 shows SQL-9 level RX TX ========== ========== C001 Channel GP SQL - 9 Figure 5. 7) LCD backlight dimmer Push rotary knob to select DIM. Dimmer level varies from DIM-O to DIM-15.

Press CH, and then 0-9 key for channel numbers Example:-1 CH-8 CH + 0 + 0 + 8 Example-2 CH-500 CH + 5 + 0 + 0 9) P-25 Squelch control Press SHIFT then MON to choose P-25 squelch mode. Normal SQ= If NAC is the same, then receiver will unmute Selective SQ= If NAC and GROUP is the same, then receiver will unmute If radio is called with the correct individual number, then radio will unmute.
10) P-25 PTT mode Press D to select PTT mode.
11) P-25 Calling selection Press A to select GP= group call, AL= all call, ID= individual call Figure-11 shows group call 500=TGID (talk group ID) Figure-12 show all call, 65535=all call group TGID Figure-13 shows individual call RX TX C001 Channel GP MDXN 500 Figure 11 RX TX C001 Channel AL 65535 MDXN Figure 12.
12) Individual call (target call) This function works only selected Individual call in Para-11 Press B, and enter 0-9 for individual numbers. Press B or # to complete entry. To clear, press * to erase the last entry. Figure-14 shows to start entry, pressing B Figure-15 shows to complete entry, 1 +2+3+4+5+B RX TX C001 Channel ID __ MDXN Figure 14. RX TX C001 Channel ID 12345 MDXN Figure 15.
14) Key lock SHIFT+8 = Key lock. This symbol shows on LCD However, PTT, MON and SHIFT key are not locked. If you need to lock these 3 keys, then you may select in Programming software as DISABLE. If the station is to be remotely controlled it is recommended to leave PTT enabled, Remote PTT will not work when PTT is locked. To release key lock, press SHIFT+ 8 again.
16) P-25 Status data Press SHIFT+* shows the following modes, every 1.5 seconds to move when * is depressed. 1/ Unit ID (source address) 2/ RX NAC 3/ TX-NAC 4/ TGID However, these functions must be enabled in software at MISCELLANEOUS menu; INFORMATION DISPLAY-ENABLE Figure 20 shows SHIFT+* indicating Unit ID code RX TX C001 Channel Unit ID 1 1 9 3 0 4 6 Figure 20 17) Bar Graph/ Channel Display Press SHIFT+CH to eliminate bar graph. In turn, current working frequencies are shown on LCD.
18) LCD back light hold By Default, back light illuminates for 5 seconds after any key press then goes out. Press SHIFT +1 for back light hold. Press SHIFT+ 1 again to be back normal. Figure-below shows back light turns on. RX TX C001 Channel GP Light turn ON 19) Changing TX power Press SHIFT+2 to select High and Low TX power. shows high power. If the radios are pre- programmed Hi-Lo power with programming soft, SHIFT+2 overcomes this pre-program level. Figure-below shows Hi power with SHIFT+2.
21) Emergency call reception In the 4th line of the LCD shows EMG when emergency received. LCD back light is flashing and audible tone out from speaker. Figure-below shows Emergency caller's ID 98765. RX TX C001 Channel EMG 98765 22) Repeater mode BASE TECH III repeats automatically when programmed as a repeater. a) Rx mode = digital Repeats only the same NAC code. If the NAC is $F7F, all incoming signals are repeated. . Repeating shuts automatically after 0.0-9.
24) P-25 Test mode Press SHIFT+ 0 to move test mode. The table for test mode are; 1/ Standard transmitter test pattern 2/ Standard transmitter symbol rate pattern 3/ Standard transmitter low deviation pattern 4/ Standard transmitter C4FM modulation fidelity pattern 5/ Standard tone test pattern Press the PTT to transmit above patterns. To change patterns, press key 1-5. Figure-23 shows test mode, LCD indicates from 1 to 5 alternatively.

25) Adjust mode Ground the TP-2 on the analog logic board, and switch on the radio. Then the following parameters are adjustable. 1/ RX AK2344 VR4... Rx 0dBm output level 2/ RX FX828 MOD-1... Deviation level at the repeater mode (analog) 3/ TX FX828 MOD-1... Deviation level (digital) 4/ TX FX828 MOD-2... Deviation level (analog) Press A and B to adjust the level, and # key for changing mode. Cycle power to radio to return to the normal mode.
26) Key test Keep depressing C and switch on the radio, then radio comes to Key test mode. Figure-34 shows key test mode Please Key - in Figure 34 Then depress any key to test. Figure-35 shows CH key depressed.
27) Displaying firmware version Both firmware and DSP soft version are indicated on LCD after the radio switch on for 2 seconds. Figure-38 shows when “no start message” is programmed <71BS V100 710 Figure 38 Figure-39 shows start message “Your Messag Here” is programmed Your Messag Here Figure 39 28) Displaying serial number Press D and switch on the radio, the serial number is indicated. (max 8 digits). Releasing D key, the radio starts normally.

31) Error Displays Either RX PLL, TX PLL or PA power is defective, then ALM LED flashes on and indicates which unit becomes faulty. Figure-43 shows RX PLL error, Note this may be displayed in REM mode if the remote channel lines are open or a channel is selected remotely that is not programmed. (EXXX will be displayed instead of CXXX, where XXX is the channel number.
34) DSP error detection When DSP does not work properly, the following message are shown on the LCD. Please check DSP board is firmly connected, or replacing the DSP board.
