Powering Up/Restarting

Q.Why don't I have power on the docking unit?
A.Check power is connected to the interface unit. If applicable, check the vehicle ignition is in ACC or IGN or ON position. Ensure the Connector cable to the DOCK is firmly fitted.
Q.My unit powers off once the ignition is switched off or the key is removed after 20 minutes.
A.This is normal operation; however connecting the ACC cable to a constant power source on the vehicle/vessel will rectify this, if such an operation scenario is required.
Q.The docking station keeps beeping and the Iridium handset is not turning on.
A.This is usually an indication that the Iridium handset has crashed and unfortunately even though the docking station is trying to restart the Iridium handset the phone is not responding. To resolve this problem the Iridium handset must be removed from the cradle, have the battery detached for 10 seconds, replaced and then redocked into the cradle.
Q.I want to install the docking station/terminal's DC connector directly to the car wiring, what is the pin out of the connector for the Docking Station/terminal?

The pin out looking into the 4-way connector of the Docking Station (attached).
Only pins 1, 2 and 4 are used:

Pin 1 = Acc
Pin 2 = GND (0V)
Pin 4 = Constant Vin (+VE)

Q.The Iridium handset restarts whilst docked.

Sometimes an Iridium handset may become temporarily unresponsive to the docking station.

When this happens the docking station will attempt to restart the Iridium handset to re-establish communication and correct the operation.

Customers who have assigned a sim pin will need to re-enter the simpin via the Iridium handset before Iridium registration can continue.

A firmware update may also fix this issue. Contact Beam customer support to find out the most recent firmware for the docking station and the Iridium handset.

At times, with continued use and exposure to dusty or dirty environment, electrical connection between the dock and the handset may be compromised. Disconnect power from the dock and remove battery from the handset. With a clean piece of cotton cloth and isopropyl alcohol, clean the bottom connectors. Let the surface dry before retesting.

When the handset is on PTT Mode, the dock should be at least at version 1.4 or later.

Q.My Beam Iridium docking station in the vehicle does not stay on.

It is possible that the accessory wire is not wired correctly or has been disconnected.

The dock's accessory wire should be connected to the vehicle's accessory power for the dock to benefit from the accessory connection feature.

Screenshot shows how the dock behaves relative to the accessory wire connection.

Q.My Beam Extreme Docking station does not stay on with the 9575 Extreme handset. The dock will try to switch on the handset, but unable to keep it on.

If the dock stays on without the handset, this symptom may be caused by the 9575 Extreme handset.

It is recommended to check the following:

  • The Extreme handset has two battery options, a slim battery or an extended battery.  If a slim battery is used, make sure the battery Infill plastic must be in place (Refer to Extreme Dock user manual).  The use of the infill for slim battery will make sure the handset contacts align with the docking station contacts. Remove the Infill when using an extended battery.
  • The Extreme handset is IP 65 rated therefore rubber parts may need some push to close off the gap like between the battery and the handset. Once the battery is locked in place, give the centre of the battery a gentle push down towards the handset. This will help close the handset's terminals to the battery.
  • Make sure the battery can switch on the handset when undocked. If not, try to charge the handset with the wall charger. If the handset is unable to charge through the wall charger, then the handset or the battery itself has a problem. To verify that, swap the battery from a working handset and observe.

Q.Does RF Interference affect the satellite signal?

All wireless devices, including satellite telephones, are susceptible to RF (Radio Frequency) interference from other electronic devices. This problem is especially evident when numerous antennas and broadcasting devices are located within close proximity to each other.

A good example would be onboard a ship. It is important that certain considerations be taken into account for best performance when an Iridium/Inmarsat system is installed.

Causes of RF Interference:

Some subscribers have contacted Iridium regarding the loss of signal quality when they operate their equipment near active Inmarsat terminals. The power with which Inmarsat units transmit can overpower the Iridium unit’s ability to properly maintain a quality connection with the Iridium satellite constellation. Inmarsat terminals are often found in the same locations as Iridium subscribers, such as harbors, airports and especially onboard ships.

The location of the Inmarsat unit’s antenna in relation to the Iridium unit’s antenna plays a significant role in determining the degree of signal degradation that an Iridium subscriber can expect to experience. All Iridium units are susceptible to this interference, regardless of the type of antenna being used.

Generally speaking, an Iridium unit, be it a handset using its internal antenna or a fixed terminal when attached to an externally mounted antenna and located within 15 and 45 meters (50 to 150 feet, respectively) of an operating Inmarsat Standard-C terminal, will likely experience degraded performance.

Other sources of RF interference such as Globalstar units, radar devices and broadcast stations can provide interference for Iridium units, but usually are not encountered as frequently as Inmarsat terminals.

Also refer to “Assuring Quality of Iridium Service” in the Antenna Installation Guide.

Q.My Iridium 9555 or 9575 handset can get a good signal off the cradle but when docked, I get intermittent signal and sometimes no signal at all.

The Iridium 9555 and 9575 handset have an external bypass antenna connector. As these connectors are exposed to the environment, they can get dirty and may prevent a good connection between the handset and the dock. Sometimes, the more use the handset gets with that connector, it cannot be avoided that the connector will wear off and may not offer good connectivity to the dock.

The antenna connector of the 9555 handset is at the back just above the battery while the 9575 handset is at the bottom.

Make sure the connector is clean and free from any foreign matter that may block the connection. Connectivity of the external connectors can also be verified with an accessory that came with the handset.

The 9575 comes with a bottom connector that will allow you to use an external antenna while the 9555 comes with a clip adapter for the same purpose. If using the adapter still gives you no signal, then have your handset checked by your supplier or by an Iridium authorized service centre.

Q.My PTT handset's LED indicator is blinking

A blinking LED indicator of a wireless PTT handset can mean any of the following:

1. The handset is out of range.  Bring the handset closer to the cradle (of external PTT antenna) to reestablish communication.

2. The handset has lost its pairing from the PTT cradle.  Switch the handset on, also make sure the PTT cradle is switched on.  Press the 2 blue volume buttons simultaneously for approximately 8 seconds until a consecutive beep is heard, then place the handset into the main PTT cradle to complete the pairing.  A paired handset will have its LED continuously lit when in and outside the PTT cradle.

3. The LED only blinks when I press the PTT button and the Iridium handset does not respond to PTT button press.  This is a possible hardware fault, please contact [email protected] for an RMA.

Q.Why am I experiencing more dropped calls than usual?

Due to a satellite network, if you are in motion, the satellite signal may become obstructed (such as buildings, bridges, tunnels, larger vehicles, valleys , large trees). If your satellite setup is not obstructed and yet you have no signal, you will need to perform the following checks:

Check the antenna connections.

Ensure the antenna cables are not damaged. 

Ensure that only approved antenna cable has been used.

Refer to Antenna Install Guide on Beam website support.

If problem persists, contact your service provider

Q.Why is the voice quality poor on my Beam docking station/terminal?

Voice quality may be affected by many factors. Before making a call, make sure that the signal strength is at least 4-5 bars (some terminals the signal LED should be bright green, not orange, or red). If the setup cannot achieve the signal level required, there is a possibility that there is a problem with the setup.

Please check FAQs about Signal or Antenna for more tips.

Q.I can hear a buzzing sound coming from the in-vehicle unit.

The buzzing sound usually begins when noise picked up by the power supply or the audio circuit and manifests as a buzzing sound to the in-vehicle unit.

Identify the source of the buzzing sound by switching the car radio off.

Also observe whether the buzzing sound is influenced by external interference from outside the vehicle, trains, large machinery, other communication equipment.

Buzzing sound may be suppressed by incorporating power supply filters. Consult a local electronics shop for advice.

Q.I hear a lot of background noise while on the call.

Make sure that the signal level is between 4-5 bars.

If you don't achieve that, check the components of the setup and the installation.

Check the location of microphone (if applicable), make sure it is not located near an air vent or too close to an open window.


Q.The Iridium PTT handset reboots intermittently when docked during PTT mode. This does not happen when on Phone mode.

When the ExtremeDD is not on a PTT compatible firmware (1.4.8025 or greater) it will not work well with an Iridium PTT device.

To update the ExtremeDD firmware, download the latest version of Eagle on the product's support page.

Q.How can I integrate the DriveDOCK Extreme with another PTT console or accessory?

The DriveDOCK Extreme not only works with Beam PTT approved accessories but can also be integrated to any third-party PTT console or accessory provided the electrical interface match.
