Using the Measuring Handset
The idle screen
The LCD screen shows the following information in the idle screen:
Indicates the signal strength between the base station and
registered handset.
Weak to strong:
No reception:
Indicates the current battery status.
Low to full:
Need charging: (red)
Values for determining the connection quality:
RSSI: Base station signal reception strength with the best
reception in dBm.
Recommended value: -27 to -85 dBm.
Note: The RSSI value is displayed in dBm as standard, you
can change it into a percentage value.
Fr. quality: Frame quality. Percentage rate of the packages
received without error in the last measuring interval.
Recommended value: 100%.
Base Station: RPN (Radio Fixed Part Number) of the base station.
Identifier for the base station to which the handset
is connected.
Frequency: Carrier frequency of the signal received.
Value range: 0-30.
Slot pair: Time slot for the reception channel on which the
measurement was performed.
Duplex Slot pair used (0-11).

Configuring Metering Mode
The measuring handsets are already in the metering mode out of the box.
Note: The handset backlight is always on in the metering mode, so the screensaver does not work.
To change the settings for metering mode:
1. Enter the code *1234203# in the idle screen to activate metering mode.
2. Press the OK key to enter the main menu, and then select Settings->Telephony->Metering Mode.
3. Select the desired unit (dBm or %) for RSSI.
4. Select the desired measurement interval.
Value range: 5-15 (0.8s-2.4s). Recommended value: 6.
5. Press the Save soft key.
To exit the metering mode:
1. Press the OK key to enter the main menu, and then select Settings->Telephony->Metering Mode.
2. Disable the metering mode.
3. Press the Save soft key.
Taking Measurements
1. Select the first measuring point, and mount the base station on a proper location of the stand.
Deployment Toolkit
2. Set up communications between two handsets, and measure the radio coverage.
You can connect headsets to the measuring handsets so that you can assess the quality of the sound
transmitted from the measuring base station. It also means that your hands are free to enter the locations
determined in the plan and you can read the LCD screen during the measurement.
Note: The handsets are already registered to the measuring base station out of the box. If two people perform the measurements, you
can check the voice quality by establishing a connection between the two measuring handsets. If you perform the measurements
alone, you can enter #*9 via the keypad to place an analog call.
3. Check the current status values of the connection to determine the second location of the base station.
The recommended RSSI value is between -27dBm and -85dBm, and the Frame quality is 100%.
4. Move the base station to the second location, and adjust the base station to a proper position of the stand.
5. Repeat steps 2 and 3 to determine more locations of the base station.
