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 PNG Control Panel in the aircraft. In addition, the Base Station can be connected to a moving map system and send handheld position data at regular intervals. The PNG Base Station is typically connected to the aircraft ICS, and may support multiple connection points for audio. The base station is capable of delivering a PTT signal to other systems, as well as triggering transmission based on a received PTT signal or VOX activation.
Axnes AS Section 2: Operation The PNG system consists of one base station and one or more handheld radios (MP30). 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 MP30 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 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. Note: Some active headsets have AC coupling of the microphone signal, which may affect the microphone detection. With those headsets, manual microphone selection may be required.
Axnes AS General UI GPS antenna Two-character dot matrix display Headset connector Microphone Primary PTT (PTT-1) Menu Volume Up/On Volume Down/Off Configuration up/down Secondary PTT (PTT-2) OK The MP30 is equipped with a small dot matrix display located at the top, angled to be readable from front and top.
Axnes AS Initial Scroll buffer SR search and rescue The display can show two letters at a time, and implements scrolling of text to display longer strings. Most menu entries are therefore presented with a two-letter acronym, before the full menu name is scrolled. Power on/off The MP30 is turned on by pressing the volume up/ON button. The MP30 will start up in the last used configuration/mode. At power up, the configured name of the unit is displayed.
Axnes AS Display indications Searching for intercom: When the MP30 is turned on and searching for intercom, the display will indicate active searching with two alternating blinking dots in the display. The alternate blinking dots will stop as soon as a connection to the base station and intercom has been established. The vertical position of the two blinking dots indicates the battery status.
Axnes AS Receive: When the MP30 is receiving, a blinking arrow pointing downwards is displayed. The position of the arrow indicates the signal strength in three levels: Good, fair and weak. Good Fair Weak Direct mode indication: When the MP30 is in Direct mode (UHF FM mode), a ‘D’ will be blinking in the display in standby mode Battery full Battery low Local mode indication: When the MP30 is in person-to-person/Local mode, ‘L’ will be blinking in the display in standby mode.
Axnes AS Adjusting volume Depending on the headset/helmet connected to the MP30, the volume may be individually set to preferred volume by using the volume up/down buttons on the side of the MP30. When the MP30 is power off-on cycled, it will start up with a default volume setting. VOX / PTT mode When a headset is connected to the MP30, it will by default be set to VOX mode. It will remain in VOX mode until PTT mode is activated by pressing the primary PTT button.
Axnes AS 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 MP30 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 analogue FM radio without encryption over the UHF 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 UHF 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.
Axnes AS Bluetooth The MP30 has an optional Bluetooth audio interface. The MP30 may connect to a mobile phone allowing the MP30 user to communicate over the phone line from the MP30 connected headset. Bluetooth pairing: The first time a mobile phone and the MP30 shall be paired (connected), the MP30 must be made visible for other devices. This is done in the MP30 Bluetooth menu, setting it “VISIBLE”. This will make MP30 visible for 2 minutes and the phone should be connected during this time.
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 PR Parameter Reset RE Return CO Confirm Squelch: The Squelch setting is only valid in direct mode, and the menu is not available in intercom 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.
Axnes AS VOX Maximum Level: When the VOX trigger level increases because of ambient noise, the trigger level can never pass the VOX maximum level, even if the ambient noise indicates that a higher trigger level should have been used. The setting is persistent over a power cycle. VOX Minimum Level: The equipment is by default set to minimum VOX level when VOX mode is entered. The VOX trigger level will increase as the environmental audio conditions force the level up.

Axnes AS The following non-spoken audio feedbacks are given: Short Bip: Key press indication on volume, configuration, menu and OK keys. Short Bip-Bip: A very short audio feedback to indicate audio decode failure. The MP30 has detected a transmission from the PNG Base Station, but not been able to receive and decode fully. Caused by poor radio conditions. Congestion Biiiip------Biiiiip: Audio feedback to indicate that uplink communication cannot be allocated from MP30 to PNG Base Station.
Axnes AS Trouble shooting Problem No communication with the intercom Possible solution If no communication with the intercom can be established, the following should be checked: Check that MP30 operates in intercom mode, refer to section 2.14 Changing direct/intercom mode, and section 2.7 Display indications. Check that MP30 and the PNG Base Station configuration are set correctly, refer to section 2.13 Changing configuration/channel.
Axnes AS should be adjusted to the appropriate level. Refer to squelch setting in section 2.18 Menu. No reception in direct mode If the MP30 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 2.18 Menu. Unit will not charge If the MP30 will not charge when installed in the charger, the following should be checked: • Check the MP30 temperature. MP30 temperature should be between 0°C and 50°C.
Axnes AS If the problem still persists, the MP30 should be sent for service at an Axnes authorised repair centre.
Axnes AS Section 3: Recommended maintenance All units should be kept clean and charger contacts should be kept free of corrosion. The CHG30 and CHG35 are operated on condition, and no service intervals are recommended. CHG35 has rubber details, to keep MP30 in correct position. If friction between the CHG35 and MP30 gets too high, the MP30 can be experienced to be sticky to the CHG35. The rubber details can then be lubricated with silicone paste or other suitable lubrication.
