The MicroAlertÔ radio / microwave alarm is the size of a small pager. This unique detector is ideal for anyone trying to find out exactly WHAT'S emitting radio or microwaves, whether in HIDDEN locations or in plain sight!
A clear loud beep indicates radio waves stronger than the level you select. If you move closer to the radio / microwave source, the beep sounds more frequently, and will ultimately become a solid tone if you move in even closer to the source. As you move away from the source, the beeping will stop. Minimum sensitivity is only .1 microwatt per cm2, making it much more sensitive than the radio / microwave setting on the original TriField Meter!
At the highest sensitivity, it will detect a typical cellular phone tower 1/2 mile away, a typical analog cell phone 40 feet distant, a digital phone at 20 feet, and a microwave oven (in use) 10-50 feet away (usually with a less sensitive setting). The device is most sensitive from 6 MHz to 3 GHz, thus ordinary cordless phones cannot cause much interference (detectable at about 2 feet).
The MicroAlert Alarm is shipped set so STANDARD sensitivity threshold is about 5 microwatts / cm2. Sensitivity can be reduced to 1 microwatt / cm2 by adjusting the side knob.
Radio / microwave surveillance "bugs" / devices can be detected within one to two feet of the instrument.
A control knob on the side can raise or lower the overall sensitivity. The unit chirps once each time you turn it on to indicate that the battery is good. With the sensitivity on "high", you'll be amazed where and how frequently you find radio / microwaves!
The MicroAlertÔ Alarm comes with a one-year warranty, replaceable battery, and a pocket clip.Astonishment will permeate your brain as you uncover sources of STRONG radio and microwaves in places you'd never suspected, like some wall outlets and yet not ALL wall outlets in a building or office area.
A great dinner conversation piece in restaurants when someone at the next table uses a cell phone and sets off your MicroAlert (IF it happens to be ON), gently letting the caller know they are "invading your air space."
"As you move closer to the source or turn the face of the MicroAlert toward the source, the chirps will signal more frequently, and will become a solid tone above around 10 and 50 milliwatts / cm2, respectively. Of course if you turn away, or cover the front with your hand, the chirping will become less frequent or will stop altogether."
Try it first on HIGH sensitivity. The unit will chirp once it is turned on. The device will chirp repeatedly when exposed to over 1 microwatt / cm2 on HIGH sensitivity, or 5 microwatts / cm2 on STANDARD. As you move closer to the source or turn the face of the MicroAlert toward the source, the chirps will become more frequent, or will stop altogether. Use the self-adhesive clip, if desired, on the non-printed face of the unit. For maximum sensitivity, keep the printed side toward you in your pocket.
The standard version is sensitive from 6 MHz to 3000 MHz or 3 GHz. It can be used to detect cell phones, cell towers, microwave ovens, and radars (including police radar).
On high sensitivity, you will notice that it's sensitive to cell towers to a distance of 1/2 mile, which might be TOO sensitive so you may want to try lower setting. You can determine relative sensitivity by holding the non-printed surface near a fluorescent light or video monitor..... a HIGH setting should detect either one. Sparks from static discharge, also emit radio waves, and can occasionally cause a chirp.
