Axnes AS Section 1: General information Axnes AS has delivered the Polycon system to the rotary wing Search and Rescue segment for decades. The system is widely adopted in this segment. The PNG system is based on the functionality in the previous system, but enhances the functionality and performance based on user feedback. The PNG system incorporates the following main features: • • • • • • • • • • • • • • • • • Wireless extension of aircraft intercom system with significant range and robustness.
Axnes AS The MP50 is available in two versions, MP50 with Li-Ion battery and MP50M with NiMh battery. Through the internal microphone in the MP50, it is possible to communicate with the survivor/ground rescue party without helmet removal. Depending on the configuration and part number, the MP50 is equipped with a GPS receiver. The position of the MP50 may be polled by the PNG Base Station, and presented on the PNG Control Panel in the aircraft.
Axnes AS Section 2: Operation The PNG system consists of one PNG Base Station and one or more handheld radios (MP50). To make all units in the PNG system interoperable, each unit must be configured with compatible parameters. Configuration of the PNG system will imply setting of radio frequencies, defining groups and setting scrambling and encryption parameters. Multiple configurations may be stored on a device to support different operational modes.
Axnes AS Configurations Both the MP50 and the PNG Base Station use configurations to control the behaviour of the devices. They can hold a number of configurations, with different operation parameters.
Axnes AS Microphone detect The MP50 implements active microphone detection when a headset is connected. The MP50 will identify the microphone type and set parameters for gain, impedance and bias accordingly. The active microphone detect can be disabled in the menu, and microphone type can be manually set. It is recommended to use active microphone detect. If no microphone is detected, the MP50 will be in walkie-talkie mode.
Axnes AS The primary PTT is protected by extrusions to avoid inadvertent activation, as well as allowing localization of the button when operating in low visibility. The volume control and power ON/OFF buttons are located on the side of the unit. There is also an AIS button for activating sending of position reports compatible with the AIS system. Activation of position reports will send AIS-SART formatted messages. The AIS compatible functionality can also be activated remotely from the PNG Control Panel.
Axnes AS Power on/off The MP50 is turned on by pressing the volume up/ON button. The MP50 will start up in the last used configuration/mode. At power up, the configured name of the unit is displayed. If no specific name is configured, the MP50 displays the last four digits of the serial number. If the MP50 is turned on in intercom mode, it will immediately start searching for the base station.
Axnes AS Charging: When the MP50 is placed in a charger, the charge status is indicated with a battery symbol and a bar indicating the charge status. The battery is animated when charging and steady when charging is prevented (due to temperature) or battery full. Battery full Battery low Transmit: When the MP50 is transmitting, the transmit status is indicated with a blinking arrow pointing upwards. Receive: When the MP50 is receiving, a blinking arrow pointing downwards is displayed.
Axnes AS Direct mode indication: When the MP50 is in Direct mode (maritime VHF), a ‘D’ will be blinking in the display in standby mode Battery full Battery low Local mode indication: When the MP50 is in person-to-person/Local mode, ‘L’ will be blinking in the display in standby mode. AIS indication: When the AIS functionality is active, ‘A’ will be blinking in the display. Walkie-talkie mode The MP50 can be connected to a headset or it can be used as a handheld walkie-talkie when conditions allow.
Axnes AS Adjusting volume Depending on the headset/helmet connected to the MP50, the volume may be individually set to preferred volume by using the volume up/down buttons on the side of the MP50. When the MP50 is power off-on cycled, it will start up with a default volume setting. The volume in walkie-talkie mode and headset mode are set individually. VOX / PTT mode When a headset is connected to the MP50, it will by default be set to VOX mode.
Axnes AS The MP50 has automatic VOX sensitivity. When starting the MP50, the VOX trigger level starts at the VOX Min level (set in the menu). If the ambient noise level rises, the VOX trigger level may adaptively increase. The VOX trigger level will not adapt to lower ambient noise, and user intervention may be required. The maximum possible VOX trigger level is limited by the VOX Max level (set in the menu).
Axnes AS Local mode The MP50 has an internal microphone which can be used for casualty communication, by activating Local mode. Local mode is available when a headset is connected. In Local mode, audio picked up from the surroundings is mixed with any radio received audio and injected into the headset, and allows communication with individuals around the operator without removal of the helmet.
Axnes AS communicating over the maritime VHF band. Switching between intercom mode and direct mode is done by pressing both configuration buttons (up and down) simultaneously. When changing mode, the last used VHF channel or last used intercom configuration is activated. Key lock The configuration and menu keys are protected with key lock to avoid inadvertent change of operational mode. The keys are unlocked by pressing OK and MENU simultaneously. Key lock is reactivated after 20 seconds of inactivity.
Axnes AS AIS The MP50 has implemented an AIS-SART compatible device location beacon. This is an optional feature. The position of the MP50 can be sent as AIS-SART compatible position reports. This functionality can be activated either from the MP50 using the AIS-button, or it can be activated remotely from the PNG Control Panel. Note: The MP50 is not an AIS-SART transponder. The MP50 implements functionality to send AIS-SART compatible messages, to improve ongoing operations.
Axnes AS Menu The first push on the MENU button will activate the last used menu entry. The configuration up or down buttons are used to navigate the menu tree. The OK button will select the active entry or setting, and configuration up or down will increase or reduce the value of the selected entry. The MENU button will step one level up in the menu hierarchy.

Axnes AS *Note: Menu entries are visible dependent on device configuration or mode. Squelch: The Squelch setting is only valid in direct mode. Squelch is used to separate white noise from actual transmissions, by adjusting the receive trigger level. Increasing squelch will block white noise and weak transmitters, while reducing the squelch will let weaker transmitters through. The actual setting of squelch is dependent on the operational environment. The setting is persistent over a power off-on cycle.
Axnes AS Software Version: Select what to show with the configuration up and down buttons. The following information can be displayed: • • • • • • • • Main SW version Crypto Key Name Battery Gauge parameter version CRC of the configuration (can be used to identify the configuration) Capabilities programmed Programmed serial number (Shall match S/N on the Label) Boot SW version SW hash of main SW. Parameter Reset: Reset the parameters that can be modified from the Menu back to factory default values.

Axnes AS If error condition is persistent, the MP50 should be sent for service at an Axnes authorised repair centre. It should be noted that GPS malfunction will not prevent use of the MP50. The GPS status is checked by pressing the OK button in standby. GPS malfunction will be reported as ‘GPS Error’.
Axnes AS No reception in direct mode Unit will not charge should be adjusted to the appropriate level. Refer to squelch setting in section 2.19 Menu. If the MP50 does not receive in direct mode, the squelch may be set too high. The squelch should be adjusted to the appropriate level. Refer to squelch setting in section 2.19 Menu. If the MP50 will not charge when installed in the charger, the following should be checked: • Check the MP50 temperature. MP50 temperature should be between 0°C and 50°C.
Axnes AS Section 3: Recommended maintenance All units should be kept clean. The MP50 should be rinsed off with fresh water after exposure to salt water, and charger contacts should be kept clean and free of corrosion. The CHG50 and CHG55 are operated on condition, and no service intervals are recommended. CHG55 has rubber details, to keep MP50 in correct position. If friction between the CHG55 and MP50 gets too high, the MP50 can be experienced to be sticky to the CHG55.
