SURECAL CELL SIGNAL TESTER GUIDE
INTRODUCTION
FEATURES & SPECS
The CM-Meter-01 RF signal meter by Cellphone-Mate 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.
Features
• Five bands: 700 & 800 & 1900 & 2100MHz-(LTE, Cellular, PCS and AWS)
• High Receiving Sensitivity -110dBm
• Three selectable modes
• Controllable backlight for dark environments
• Rechargeable design with four AAA batteries
• Long working time (2.5 - 3.5 hours)
• Easy to carry

INTRODUCTION
CELL SIGNAL OVERVIEW
Cell signal in Canada is provided over large range of frequencys. As a general rule, lower
frequencies are able to service larger rural areas while higher frequencies service areas of
higher population density. So for most users checking the lower frequency signals is the
information you are looking for. These are the lowest frequencies used by the major
players.
There are essentially 2 national networks for LTE. Telus/Bell and Rogers.
•TELUS/BELLuse Band 17, 13 which is 734 –746 MHz and 746 –756 MHz
•ROGERS use Band 12, 13 which is 729 –746 MHz and 746 –756 MHz
•SASKTEL use Band 13 which is 746 –756 MHz
Test the Bands
•For Band 17 select LTE AT&T
•For Band 12 select LTE AT&T
•For Band 13 select LTE VERIZON
It’s important to note that these are the frequencies in rural area’s, if your near a large
population center, LTE service your receiving will be on a much higher frequency. For
example:
BELL/TELUS have repurposed some of these bands for LTE, what block to test depends
on provider/ location. Typically Block B or D is what you are looking for. Some of these
frequencies may not be used at all in rural area’s. Band 4 is also used by ROGERS in
some areas.
•Band 5 which is 869 –894 MHz Test CLR 800
•Band 2 which is 1930 –1990 MHz Test PCS 1900
•Band 4 which is 2110 –2155 MHz Test AWS 2100

SETUP
POWER & CHARGING
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.
ANTENNA USE & INSTALLATION
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 Interface uses the included high gain antenna with SMA cable connector to
gauge the best outside RF wireless signal for installing or adjusting a directional
outside antenna.
Step 1: Attach the SMA end of the antenna jack on the top of the signal meter.
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
[e-mail] to find out how.

What is good signal
Good Signal
Signal greater than -85 dBm
Marginal Signal
Signal between -85 and -100 dBm
Bad Signal
Signal less than -100 dBm
UNDERSTANDING THE KEYPAD
There are four keys for user actions (see keypad example
above) 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
OPERATING
UNDERSTANDING THE SCREENS
There are four lines of information available to users:
•The top line displays detecting mode (see table below) and battery life
•The second line displays band
•The third line displays detecting block in Mode-I, detecting frequency in Mode-II and
detecting bands frequency range in Mode III

3G Testing
TELUS/BELL/SASKTEL
You will want to check three frequencies and bands when testing 3G network strength in a given
area. JDM-150 only operates in 3G, GX-450 can run 3G or LTE. Signals greater than -85 dBm is a
good signal. Signals less than -100 dBm are poor signals. These frequencies are also used for LTE
coverage, so this is currently the most insightful numbers for both JDM-150 and GX-450 Modems
CELLULAR 800 –Block “B”
5) Press band select twice
6) Push next frequency once
PCS 1900 –Block “B”
3) Press band select three times
4) Push next frequency once
PCS 1900 –Block “D”
1) Press band select three times
2) Push next frequency three times
Between all three of these bands you should be able to understand better
what the cell signal is like in a given area. Still the best way to test proper
cell reception is with a full RTK system hooked to a PPN modem and
booster. The quality of the signal received is available from the GX-450
Admintool. Contact PPN if you have any questions about getting setup with
the new GX-450 admin tool located in the order tool area of the PPN
website.
