Press the MENU key, it will display Group, up and down have corresponding variation, at last, press the MENU key to lock, and it will appear static condition. 12.4. When

45、 the signal from ANT.A input, the LCD display the ANT.A, the signal from ANT.B input, the LCD display ANT.B. 12.5. During press the key, check if the LCD will appear abnormal problem, and it has corresponding variation. 13. Turn on and down the unit for 3 times, the unit should without the crashed p

46、roblem. The display will be decreased for 2-3 seconds in delay. 14. The consumption current is less than 230mA. 15. SQ factory presets: set in 5 condition - 21 - AU-800H Instruments: 1. signal generator: 8903b 2. oscillograph: LS8106 3. modulator: JMM-2200 4: frequency recorder: EFC-3203A 5. DC powe

47、r supplier: 3303A. 6. multi-meter 7. frequency spectrum: E4403B Instruments Setting: 1. signal generator: 1kHz/65mV. 2. modulator: 2.1. Tone set: H: Pass: 3K L: Pass: 50K RANGE: 10 2.2. AF set: H: Pass: 25 L: Pass: 15K RANGE: 50 Test procedure and specification: 1. Turn on the power supply (press th

48、e ON/OFF key for 2 seconds), the LED indicator will light up, after the LCD show the battery and frequency status, the bright of LED indicator will be decreased. 2. Test the sense power of PL2 on CH1, CH6, CH12 are above 5dBm, the sense power of PL1 is above 1dBm, the sense power of PL0 is above -5d

49、Bm, and the harmonics is below -45dBm. (note: the power of PL1/PL2/PL0 must have obvious variation) 3. Input signal from MIC input terminal (shout), the modulator should have output. 4. Tone test: Tone signal is in 3KHZ0.5KHZ, the frequency is in 3134KHZ. 5. Test that the radio frequency is in standard range, permit the error in 2KHZ. 6. Functions test: 6.1. Switch the CH/ON key to corresponding channel, and the SELECT has
