A frequency preset stores a valid operating frequency plus an associated Waveform Profile; for example, 121.500 MHz operating with Waveform Profile WP5. When the radio is received from Park Air, all 400 Frequency Presets are set to 118.000 MHz operating with the default Waveform Profile WP1. The Frequency Preset designations are factory set to be FP1 to FP400. These designations can be edited by the user to any name up to 8 characters long. To create and store a frequency preset: (1)From the Home screen (Fig 3-39) press Key 2 to display the list of frequency presets (Fig 3-40). Fig 3-39 Home Screen (2)Pressing Key 9 to scroll up, or Key 10 to scroll down, highlight the frequency preset to be edited then press Key 12 – Edit to display the Frequency Preset Edit screen (Fig 3-41). Fig 3-40 List of Frequency Presets M7X and M7RPage 3-37Operation Back to Menu Fig 3-41 Frequency Preset Edit Screen (3)The first parameter that can be changed is the Name. A frequency preset can have any name up to eight characters long. In this example, the default designation FP1 is being changed to ‘Approach’ as shown in Fig 3-42. To change the name, press Key 2 – Change. The new name can be entered using the alphanumeric keypad. (4)When the new name has been entered, press Key 13 – Select. You are returned to the Frequency Preset Edit screen (Fig 3-41). Fig 3-42 Edit Frequency Preset Name M7X and M7RPage 3-38Operation Back to Menu (5)The next parameter is to attach a previously stored Waveform profile to the frequency preset. Press Key 3 – Change (Fig 3-41). Pressing Key 9 to scroll up, or Key 10 to scroll down, highlight the required waveform profile (Fig 3-43), then press Key 13 – Select. Fig 3-43 Select Waveform Profile (6)From the Frequency Preset Edit screen, press Key 4 – Change to select the required Frequency (Fig 3-44). Using the keypad, enter the required frequency. [Note that any offset frequency is a parameter of the waveform profile; the operating frequency should not include any offset.] If a Maritime waveform profile is selected, a channel selection is required as shown in Fig 3-45. Fig 3-44 Select Frequency (7)When the correct frequency (or channel) is shown, press Key 13 – Select. The frequency preset is now set up. Repeat this procedure for other frequency presets. M7X and M7RPage 3-39Operation Back to Menu Fig 3-45 Frequency Preset – Select Maritime Channel Channels are only available when using the Maritime waveform. Each channel stores separate predefined transmit and receive maritime VHF frequencies. Channels cannot be altered by the user. The radio can be set to either ‘Ship’ or ‘Shore’, which swaps the stored transmit and receive frequencies. Also the ‘International’ or ‘American’ frequency sets can be selected. The factory default is ‘Ship’, ‘International’, Channel 16. M7X and M7RPage 3-40Operation Back to Menu Security The radio has a security feature that allows certain operations, for example, changing the radio’s configuration settings, to be performed only after a 4-digit PIN number has been entered. The radio has three security profiles: ‰Security Profile A (SPA). SPA limits access to defined radio functions via the front panel and associated M7 remote controllers ‰Security Profile B (SPB). SPB limits access to defined radio functions via the front panel and associated M7 remote controllers ‰Security Profile Z (SPZ). SPZ limits access to defined radio functions via its interfaces (not including the interface to M7 remote controllers). The example given on the following pages show how to set security so that: (1)Personnel with knowledge of the Security Profile A PIN: ‰can change frequency by recalling stored frequency presets from the radio or associated M7 remote controller ‰cannot recall waveform profiles ‰cannot change the radio’s configuration settings. (2)Personnel with knowledge of the Security Profile B PIN: ‰can change frequency by recalling stored frequency presets from the radio or associated M7 remote controller ‰can change frequency by recalling stored waveform profiles from the radio or associated M7 remote controller ‰cannot change the radio’s configuration settings. (3)The radio’s configuration settings cannot be changed from any remotely connected equipment (except the M7 remote controller). The administrator has no security restrictions. M7X and M7RPage 3-41Operation Back to Menu To define the security profiles: This procedure should be completed only by the system administrator. (1)From the Home screen (Fig 3-46) press Key 6 – Security to display the Security screen (Fig 3-47). Fig 3-46 Home Screen – Security Set Up (2)The Security screen shows the restrictions applicable to profiles SPA, SPB and SPZ. A restriction is indicated by a cross () and no restriction is indicated by a tick (). The example shown in Fig 3-47 has no security restrictions. To set up the profiles press Key 6 – Enable Security. Fig 3-47 Security Screen (Example A) Press Key 6 to display the Security screen M7X and …

M7X and M7RPage 5-7Maintenance Back to Menu Unscheduled Maintenance The unscheduled maintenance detailed in this documentation describes diagnosis using the Built-In-Test facility and rectification by module replacement. An M7 radio weighs up to 26 kg. A minimum of two people should be used to lift the radio. Special consideration should be given if the radio has to be lifted at height, for example from the top of an equipment cabinet. Failure to take the necessary precautions can result in injury to personnel. All procedures given in this topic assume that the faulty radio has been removed from its operational position and placed on a suitable work-bench. This equipment contains devices sensitive to electrostatic discharge. Precautions applicable to handling such equipment, including anti-static work surfaces and protection using wrist straps connected to earth, should always be taken. Tools and Test Equipment The following tools and test equipment will be required to perform the unscheduled maintenance procedures detailed in this documentation: (1)Torx Screwdriver, size T10. (2)Torx Screwdriver, size T15. (3)Torx Screwdriver, size T20. (4)Frequency counter able to measure 10.000 000 MHz. (when replacing the Processor module).
