User's Guide of ISM UHF Spy Audio Bug Monitor

1.Load battery correctly. Put power switch to "ON" position and enter into working status. Extend microphone's antenna, lay or affix it at 1~5 meters away from voice source. You can monitor the local voice (adjustable free) from 10 meters away after powered on the switch and inserted earphone or speaker.
2.With correcsponding 3 way connector plugs, you can link recorder with receiver and record informaiton while monitoring.
3.The receiver is oriented when voice source is too far. Please adjust the direction of receiver. Usually make antenna vertical to the floor and turn around to find the strongest signal. When used in building concentrated area, signal density may varied a lot due to obstruction and multiple reflection, and cause blink spot eventually (the signal appear faint in short range). How to select the appropriate received spot and the position of monitor is extramely important. Put receiver at elevated or open area. Or close to window as possible when used indoor. The fewer building obstructed between receiver and microphone, the longer transmission distance you will get.
4.Transmission range is closely related with operation conditions and weather conditions. Open area is better than building concentrated area. Higher is better than lower. Vertical wave (antenna vertical to floor) is better than horizontal wave. Suburb is better than downtown. Night is better than daytime. Customer can make good use of microphone and receiver based on the characteristics mentioned above.
5.Please replace the battery in time when transfer distance is getting shortened, or voice is distorted, or hum increased, etc.
