While in the Search Mode, Memory Scan mode, and Select Scan mode, the sub dial knob is used to select the respective bank. Lit Rotate the sub dial to mo

14、ve the marker display line. Flash Press and hold this key until the MKR-LED flashes. This enables the marker to move 10 times faster than its normal speed. Lit The frequency step changes with the designated steps. Flash Press and hold this key; a small window will appear on the LCD screen. This enab

Rotating the sub dial changes the receive frequency at 10 times the rate of the main dial. 22 Dial Knobs SUB DIAL (Small knob) The sub dia

16、l knob is used to change the parameters of various settings or to change the memory bank. MAIN DIAL (Large Knob) In the VFO mode, rotating this knob will change the receive frequency. In the Memory Mode, rotating this knob will change the memory channel. (To change the memory bank, rotate the sub di

17、al knob.) In the Search mode, the Memory Scan mode, and the Select Scan mode, this knob is used to change the search/scan direction. Soft Keys There are seven (7) keys at the right of the LCD display; they are called “Soft Keys.” The bottom key is designated as the DISPLAY KEY. Unlike the other 6 so

18、ft keys, the display key is mostly used to control the functions of the LCD screen. The functions of the soft keys vary according to the function displayed on the LCD screen. The soft keys may also be used for user-defined functions depending on the displayed contents. Display example of Page 1 and

This is normal, as the microprocessor of the AR-ALPHA must complete an initializing process at the beginning of a power-on cycl

22、e. 35 2-3 Squelch Circuit In normal use, LEVEL SQUELCH is used. However, VOICE SQUELCH can be selected for search and scan operations. The LEVEL SQUELCH parameter sets the AR-ALPHA to check the signal strength of active frequencies and to only stop when the signal strength is above a preset level (w

23、hich is programmable). To select LEVEL SQUELCH, rotate the squelch knob clockwise until background noise disappears. The squelch will open only when input signal strength is above this set level. To select VOICE SQUELCH, Press the , then press the 2 key. The VSQ icon will appear at the top left of t

24、he LCD screen. Rotate the squelch knob until background noise disappears. The Squelch will open only when the received voice audio level is above this set level. To return to LEVEL SQUELCH, repeat above steps. 2-4 VFO selection The AR-ALPHA has five (5) VFOs being identified as “VFO-A” through “VFO-

25、E” at the top left of the LCD. The term VFO stands for Variable Frequency Oscillator and in modern receivers refers to stored tuneable data that contains frequency, step, step-adjust, attenuator etc. Each time VFO key is pressed, one of the five available VFOs (AE) is selected. The AR-ALPHA has an AUTOMODE setting, which in most cases automatically selects the proper receive mode, and frequency step. 37 Example of frequency entry for 162.55 MHz Press the 1 key, 6 key, 2 key, . key, 5 key, and 5 key. Press the MHz key. Example of fre
