TECHNICAL SPECIFICATIONS..............................................................9 increases. Turn the knob counter- clockwise and the output volume decreases. - SQUELCH CONTROL The job of a squelch circuit is to reduce audible noise. It eliminates noise during pauses in the audio signal by muting the receiver every time and the audio level drops below a defined threshold. The squelch control on the receiver sets this threshold. Use the squelch control with care! If the squelch threshold is too high, the squelch will not only cut out noise but mute quiet audio signals as well because the squelch responds to the detected voltage and cannot distinguish between wanted signal and noise. Besides that, a too high squelch threshold also decreases the usable range. The squelch range is 95.0dB~65. 0dB. Use an adjusting bar to adjust the squelch selector for a right squelch threshold. 4.2 FOR the UB-8H/8P SERIES TRANSMITTER 4.2.1 FREQUENCY SELECT In practice, to effectively avoid the interference from any lighting equipment, Com- puters, fax machines, etc nearby, It is usually advised to switch to another frequency to get best performance. The frequency range of this system is UHF, 740MHz ~ 769MHz, and it is divided into 16 frequency bands according to the country's EMC regulations; Each frequency band can be manually adjusted with an adjusting bar. If you want to switch a frequency, you have to turn off the unit, adjust frequency and then turn it on again. 4.2.2 BATTERY REPLACING AND CHARGING Please be advised to use only one pair of AA 1.5V batteries for power supply. Caution: Danger of explosion if battery is incorrectly replaced. Replace the batteries only with the same or equivalent type. 7
