The RF signal meter by SureCall provides accurate information of radio frequency signals. The 

device can receive the RF signal from air an installed outdoor antenna or connects directly to the 

field antenna. This device works with LTE, Cellular, PCS and AWS bands. The purpose of the RF 

Signal meter is to assist in the installation of a Signal Booster, specifically for mapping the frequency 

environment, pointing directional antennas, and maximizing signal booster coverage.

specifications or which are not defective or not covered by this warranty. 

Products sold by SureCall shall not be considered defective or non-conforming to the Buyer’s order if they satisfactorily fulfill the performance 

requirements that were published in the product specification literature, or in accordance with samples provided by SureCall. This warranty shall 

not apply to any products or parts thereof which have been subject to accident, negligence, alteration, abuse, or misuse. SureCall makes no 

warranty whatsoever in respect to accessories or parts not supplied by it.

Safety Information

This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the Federal Trade Commission 

(FCC) Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment 

generates, uses and radiates frequency energy, and, if not installed and used in accordance with the instructions, may cause harmful interference 

to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause 

harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try 

to correct the interference by one or more of the following measures:

• 

Reorient or relocate the receiving antenna

• 

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

• 

Consult the dealer or an experienced radio/TV technician for help

1.  

Turning on and Charging the Meter

The power switch is used to turn on/off the device. The power supply interface is a mini USB interface. 

You can plug the AC power supply or any power source marked DC5V into it. Make sure that the 

power source can provide over 1 amp of current. The charging light is a green LED. When it is plugged 

in and the power switch is OFF, the LED will continue to blink while it is being charged. If the AAA 

batteries are fully charged, the LED will blink once. When the charging is finished, the LED will stay lit.

Using and Installing the Antenna and Antenna Interfaces

Antenna: 

The included antenna is used to pick up an outside RF wireless signal to determine its 

strengths and weaknesses of each band to determine an ideal location to install outside antennas, for 

example. To attach, screw antenna jack clockwise at top of meter.

Antenna Interfaces

: The included 9” and 24” SMA-Male to N-Male pigtail cable connectors are used 

to gauge the best outside RF wireless signal for installing or adjusting a directional outside antenna.
Step 1:  Attach the SMA end of either included cable connector to the SMA antenna jack on the top of 

the signal meter.

Step 2:  Attach the N-male end of the cable connector to the N-female cable attached to the outside 

directional antenna.

WARNING: Attaching the cable connectors from the meter to a cellular amplifier can permanently 

damage your signal meter. If you wish to measure signal from the meter to amplifier, contact tech 

support at [email protected] to find out how.

Understanding the Screens

There are four lines of information available to users:
1.  The top line displays detecting mode (see table 1, below) and 

battery life

2.  The second line displays detecting band
3.  The third line displays detecting block in Mode-I, detecting 

frequency in Mode-II and detecting band’s frequency range in 

Mode-III.

4.  The fourth line displays the detected dBm.
Note: Cellular signal reading is reflected in a negative number. The 

lower the negative number, the stronger the signal.

4.  

Understanding the Keypad

There are four keys for user actions (see keypad example)
The 

LIGHT SWITCH 

button has two functions:

1.  To turn the backlight ON or OFF, press quickly once.
2.  To change the detection mode, press the button for a longer 

period of time.

Below is a list of what the three modes represent

Mode-I

Detects the power strength of one frequency block

Mode-II

Detects the power strength of one frequency point with 5MHz band

Mode-III

Detects the total frequency power strength of one band

Note: Mode-III is likely to be used most by consumer or first-time installers
