Understanding Unit Operation Issues Key operational features of the unit may limited by the SIM/Network being used, these limitations need to be understood to ensure you get the most out of the unit.

Limitations - Selecting a Net Operator then Scanning for Signal Required Operation Issue Limitation/cause

I want to scan a 3G or 4G network/frequency on a network different to the SIM provider

After selecting the particular net operator you get an error and are unable to scan the signal

The SIM/Network will not allow you to register and as a result scanning may not work successfully, this is dependent on roaming agreements between the networks.

I want to scan the home networks 4G signal

After selecting the particular net operator you get an error and are unable to scan the signal

The APN may not be set correctly, refer Set APN (Access Point Name)

The username and password may also have to be set for 4G registration, this is usually the case for VPN SIMs

See all available Net Operators You cannot see an expected Net Operator in the found Net Operators list

There is no network/signal in your location

You have excluded a particular radio band, refer Radio Band

Understanding Scanned Signal Data To check signal, particularly in areas of poor signal, it may be necessary to scan for an extended period of time as signal can vary significantly over time and it is the minimum values that are important for reliable cellular performance.

It can also be important to consider the number of neighbour cells available as these can provide backup in the event of a particular cell becoming unavailable.

Key 3G Signal Strength Parameters For 3G cellular connections, RSSI (CSQ) and EC/IO are the key parameters to review in deciding whether a signal is adequate, note that additional parameters may also be relevant and are displayed by the signal strength meter under the Status, Network Menu.

CSQ Signal Strength EC/n0 Signal Quality

Signal<10 Weak -11≤Signal Poor to Fair

10≤Signal<15 Low -6≤Signal<-11 Good

15≤Signal<20 Medium -6<Signal Excellent

20≤Signal<25 High

25≤Signal Strong

Key 4G Signal Strength Parameters For 4G cellular connections, RSRP and RSRQ are the key parameters to review in deciding whether a signal is adequate, note that additional parameters may also be relevant and are displayed by the signal strength meter under the Status, Network Menu.

RSRP Signal Strength RSRQ Signal Quality

Signal<-120 Weak -12≤Signal Poor to Fair

-120≤Signal<-105 Low -12<Signal≤-9 Good

-105≤Signal<-90 Medium -9<Signal Excellent

-90≤Signal High

Note Registration to 4G networks can take longer than normally expected and depends on the network/SIM. When changing some settings in the unit you may be asking the device to disconnect then search/register to a different service and this process may be delayed. After making a menu selection you may need to wait for up to 40 seconds for a selection to be completed and the menu system to be active again.

Min USB The Mini USB located on the top left of the unit is used both for programming the unit using a terminal program as well as for charging the unit.

SMA Antenna Connectors Two SMA Jack antenna connectors are located top centre of the unit. A suitable antenna(s) can be connected directly or via the use of an adaptor if required. FME adaptor included with unit.

Note it is recommended that scanning be performed using the antennas that are intended to be deployed, in the location/mounting arrangement intended. Results can vary significantly between antennas and with differing location and mounting arrangement.

SIM Holder The units SIM holder is located top right of the unit. Please take care to ensure the unit is off when the SIM is removed or inserted, also ensure that the SIM is inserted correctly.

Starting the Unit After ensuring the unit is off, insert a suitable SIM card and connect your antenna of choice. We recommend that the SIM PIN (if applicable) is deactivated before inserting in the unit.

If the unit has sufficient charge then depressing the On/Off button will start the unit.

After the unit has successfully started the following screens should appear.

Main Menu – 1. Scan Signal

Scanning for Signal Strength Use the UP and DOWN buttons to select 1. Scan Signal and then press ENTER.

To start a new scan press any button and you will return to the main menu then select 1. Scan Signal again. To scan another network or frequency band refer Scanning a Different Network or Radio Band .

Checking IP Connectivity

Use the UP and DOWN buttons to select 2. ISP Connect and press ENTER.

Open ISP confirms that the SIM and ISP login details are correct and that a successful logon occurs. Possible errors may come from incorrect authentication details, incorrectly configured SIM or no signal.

Ping confirms that once logged on to the ISP a remote server can be reached.

Once ISP testing is finished use the UP and DOWN buttons to scroll to Return->Main Menu and press ENTER.

Both IP1 and IP2 must be set.




Main Menu - 3. Network Operators Signal strength and cell information for available networks can be scanned from a SIM of any valid network operator. Note that registration on the network and ISP connectivity testing (see above) is only applicable for the network which provided the SIM.

Scanning a Different Network To scan the signal from a different network, at the Main Menu use the UP and DOWN buttons to select 3. Net Operators.

Then once the screen below is shown use the UP and DOWN buttons to select the desired Network to be scanned.

Once the desired network is selected by pressing ENTER, the unit will wait for a response from the network and then return to the main menu.

Once back at the main menu 1. Scan Signal can be selected and the signal strength on the new network scanned as required.




Main Menu – 4. Status The Status section provides additional information on the current network connection as well as details of the unit’s battery status and firmware version.

Press the UP and DOWN buttons to select 4. Status and press ENTER to access the unit status details.

System Details
