NEW This device is a professional use Fix-type mobile phone detector for prisons and other places where mobile phones are prohibited to use. It is made for easy use, without annoying/ complicated settings, no need for professional electronic training or knowledge.

#DUAL ALARM OUTPUT

This device has two sets of alarm outputs, one is ANTI-Cut Waring through the NC two-line output when the power is failure. 

Another set is a Detection Warning through the NO-COM-NC three-line output when this device detects the mobile phone signal.

 # BACKUP POWER (Rechargeable Batteries)

This device has backup power from AAA / UM-4 rechargeable battery x 4 which
can support this device operating for three hours after power failure. Note: This device is available with rechargeable batteries ONLY.

# Not Easily Interfered With by Other Signals Other Than Mobile Phones

This device is specially designed to detect the GSM / 3G / 4G / 5G mobile phone signals. It has good detection capability for GSM / 3G / 4G / 5G (3300~3700MHz) mobile phone signals and does not interfere with the radio waves of other frequency bands than mobile phones. 

# INDIVIDUAL FREQUENCY BAND SENSITIVITY ADJUSTMENT

The distances among the base stations in each place are different. If the detection location is near a base station, the powerful base station signals might cause interference to this device the general detectors will alert. This device joins the feature of Individual frequency band sensitivity adjustment, in which the user can adjust the sensitivity of each frequency band to fit different detection sites and eliminate the interference of neighboring base stations and conduct effective detection.

Press the + - button on the left side at the same time, this device  enters sensitivity adjustment mode, the green scan LED stays on the  first channel, the LCD screen will appear the asterisk * on the L band 0700, the asterisk * means that the frequency band 700MHz is adjusting now,  and the upper left of the screen shows SEN = 15, which means the factory  default sensitivity level. * If the user has reset the sensitivity level, it will appear at the previous setting level.      

# CLEAR LCD DISPLAY OF SETTINGS & SIGNAL INFO

The LCD screen displays the settings of Sensitivity level and Warning mode. When detecting mobile phone signals, the LCD screen will display the frequency band, the signal strength (dB value), and bars of signal strength. Both ordinary users and professionals can smoothly check whether someone is using a mobile phone or remote monitoring devices using mobile phone technology.

# SENSITIVITY BENCHMARK & LEVEL

1. This device has three benchmarks for user to choose the appropriate benchmark according to the environment, default is Medium benchmark sensitivity level 15.

2. After entering sensitivity adjustment mode, press the ＋ or － button on the left side to change the sensitivity level. Sensitivity levels 00 - 09 are the Low benchmark, 10 - 19 are the Medium benchmark, and 20 - 29 are the High benchmark.

# WARING MODE

 Default is B = Beep + Relay output   W= B 

# DETECTED FREQUENCY BAND: Hband, Lband

1. 5G Sub 6 frequency band: 3300 ~ 3700 MHz are displayed at 3500.

2. If there are multiple frequency bands of mobile phone signals existing at the same time, only one frequency band with the most strong strength will display on the screen.

 # SIGNAL STRENGTH & STRENGTH BAR

1. -＊＊db = No mobile phone signal detected
2. Signal strength display bar: Total 8 bars representing 7 kinds of signal strength

# DETECTING FREQUENCY BAND
Detecting Frequency Band: 700, 800, 900, 1800, 2100, 2600, 3500

Specifications

* There are occasional unavoidable light spots on the LCD screen, which is normal and does not affect the display of detection results.

Remarks:

• Detecting distance will be varied subject to the signal strength & cellphone model.
• For example, when detecting a big room or a high ceiling room, setting the benchmark at High (Level 20~29) can get a longer detection distance of up to 20 meters radius.
• To detect a small area, such as a prison cell or a meeting room, set the benchmark at Low (Level 0~9) that could get a detection distance up to 5 ~ 6 meters radius. Then it is not easy to cause misjudgment due to the detection of mobile phone signals from the next room
• Detecting distance:Up to 20 meters
