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
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.
Understanding the Screens
There are four lines of information available to users:
The top line displays detecting mode (see table 1, below) and
battery life
The second line displays detecting band
The third line displays detecting block in Mode-I, detecting
frequency in Mode-II and detecting band’s frequency range in
Mode-III.
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.

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 support@cellphone-mate.com to find out how.

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
Note: Mode-III is likely to be used most by consumer or first-time
installers
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
Table 1 – Downlink Bands
The Band Select button will select between downlink bands.
Note: For a list of band options see table 2, following.
Table 2
The “Prev Frequency” button will switch to the previous frequency in Mode-II or previous block in
Mode-I.
The “Next Frequency” button will switch to the next frequency in Mode-II or next block in Mode-I.
“Prev Frequency” and “Next Frequency” buttons do not work in Mode-III.
