MM23772, Rev. B 7 OPENSKY OPERATION Once an OpenSky system has been selected from the available systems on your P7200 series portable radio, the characteristics described in the following sections will govern operation. 7.1 POWER ON/OFF AND VOLUME CONTROL 7.1.1 Power ON/OFF Rotate the Power ON/OFF/Volume Control knob clockwise to power the radio on and counter-clockwise to power the radio off. The radio will begin the Startup/Log On/Provision/Self-Test sequence and register on the OpenSky network.
MM23772, Rev. B 7.2.1 Buttons and Knobs The function of the button and knob controls will vary depending on the mode of operation. The primary functions of the button and knob controls when in the OpenSky mode of operation are listed in the following paragraphs. POWER ON-OFF VOLUME KNOB Applies power to the radio and adjusts audio volume. Rotating the control clockwise applies power to the radio. A single alert tone (if enabled through programming) indicates the radio is operational.
MM23772, Rev. B 7.2.2 Keypad (P7250 and P7270 Only) The keys on the keypad have special functions and are labeled using a symbol or abbreviated word describing its primary function. Numeric entry is a secondary function of the keys. Each key is described in the following subsections. Table 7-1: Keypad Functions KEY FUNCTION Primary function: Acts much as an “enter” button to activate a selection.
MM23772, Rev. B 7.3 DISPLAY The P7200 display is made up of 3 lines. Lines 1 and 2 contain twelve alpha-numeric character blocks each. The 3rd line displays radio status icons. If programmed, the display backlighting will illuminate upon power up or when operating radio controls. See the operation sections of this manual for specific display characteristics. Figure 7-2: Blank Radio Display 7.4 RADIO STATUS ICONS Status Icons indicate the various operating characteristics of the radio.
MM23772, Rev. B 7.5 TRI-COLOR LED Figure 7-3: Tri-Color LED The Tri-Color LED changes color to indicate radio status and is visible from both the front and top of the radio (see Figure 7-3). In OpenSky mode only two radio states are reflected by the LED and the status they represent are: 7.6 Green: Receiving Red: Transmitting Orange: If the LED is flashing rapidly, the radio is receiving an emergency call.
MM23772, Rev. B 7.7 LOG OFF THE NETWORK The *0## command de-registers the radio. Typically, this is automatically performed when powering down the radio. Using this method, the User ID is remembered by the radio so only the password is needed at next log-in. Manually log-off by pressing *0##. If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer required. 7.
MM23772, Rev. B 7.9 OPENSKY DISPLAY OVERVIEW The 12-character x 3-line display shows the radio status. The first two lines of the display are text lines that change in response to user interaction with the menu buttons. Status icons appear in the bottom line (line 3) of the display (see Table 7-2). 7.9.1 Display’s Top Line The display’s top line of text changes as the and buttons are pressed to scroll through the available menu options (see Table 7-4).
MM23772, Rev. B 7.10 ALERT TONES The P7200 radio also provides audible Alert Tones or “beeps” to indicate the various operating conditions (see Table 7-3).
MM23772, Rev. B 7.11 BASIC MENU STRUCTURE Table 7-4 illustrates the basic P7200 OpenSky menu structure. Menu items will vary depending upon system programming, radio hardware, and optional configurations. All menus except the dwell display menu can be turned off by network administration personnel.

See Section 7.7 for additional information. Log-in command: *1 # ## (required for encryption). See Section 7.3 for additional information.
MM23772, Rev. B 7.16 STEALTH MODE For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display light, indicator light and audible side tones.
MM23772, Rev. B 7.18 CHANGE OPERATING MODE 1. Press the or buttons to cycle through the menu until “Mode Menu” is displayed. 2. Press or to select the desired operating mode. 3. Press and use or to select Y or N. 4. Press again to make selection and return to the dwell display 7.
MM23772, Rev. B Lock out is a listening (receive) function and only blocks received calls on locked out talk groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do not apply to recent emergency lock outs. Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice calls can be heard on the radio. Talk group lock out is a scan-related feature.
MM23772, Rev. B 7.22 SCANNING 7.22.1 Selecting Scan Modes Three scanning modes are available for the radio, but only one can be active at any time. Changing the scanning mode changes the way the radio scans voice calls for all of the profiles in the radio personality, no matter which profile is or becomes active. The choice of scanning mode broadens or narrows the span of communications with all the groups in profiles you listen to, but does not affect your interaction with those groups you talk with.
MM23772, Rev. B 7.22.2 Checking or Changing Active Scan Mode 7.22.2.1 Setting the Scan Mode 1. Press the or buttons until “ScnModeMenu” appears in the display. 2. Use the or keys to scroll through the list of modes until your choice appears: Normal, None, or Fixed. 3. Press the key to activate the scan mode selection and return to the dwell display. 7.22.2.2 Duration of Scanning Mode Selections Scanning Mode selections survive power down.
MM23772, Rev. B In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list in memory called a speed dial list. Alternatively, a properly equipped radio can initiate a selective call to any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target radio. Some radios are configured to only receive (not initiate) selective calls. Selective calls are terminated if an emergency is declared.
MM23772, Rev. B If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The two are now in a private call until one ends the call, or the call is terminated due to an initiated emergency. If the called radio is involved in another selective call, “BUSY” will appear on the second line of the display. “Unavailable” is displayed when the call has not been answered after a 1 minute timeout or when the other party is not registered on the network. 7.23.
MM23772, Rev. B Table 7-7: Status of Selective Alert Messages STATUS MESSAGE 7.24.2 DEFINITION Delivering Select Alert message transmit attempt Busy Too busy – Try again Dest Down Receiving radio not logged on – Not registered Not Reg Transmitting radio not logged on – Not registered Delivered Transmission complete Unreachable No response Partial Transmission interrupted Sending a Message The sending process has three steps.
MM23772, Rev. B 7.24.3 Receiving a Message When a selective alert message is received by a radio, a four-beep tone is heard. The tone is heard only once, but the message “NEWALRT” alternates with the talk group on the main display. Up to 8 received messages can be stored. If a ninth message is received, the first (oldest) message is automatically deleted to make room for the new message. Received messages are displayed with the time and source information. To display a Selective Alert Message: 1.
MM23772, Rev. B Table 7-8: Emergency Calls vs. Emergency Alerts EMERGENCY ALERT EMERGENCY CALL An Emergency Alert message is sent to the dispatcher console. The dispatch console plays an emergency tone when it receives the message. An Emergency Alert message is sent to the dispatcher console. All peers (radios and consoles) and the dispatch console play the emergency tone whenever an emergency call is detected.
MM23772, Rev. B With “No Scan,” only the emergency tone is heard, not the initial open mic transmission. To dismiss or ignore the emergency, refer to Section 7.26.3. 7.26.3 Dismissing an Emergency The “Dismissing an Emergency” function allows you to “ignore” an emergency declared by another user. An emergency is dismissed for a configurable amount of time (default = 5 minutes). 1. After receiving an emergency call, press the or button until you see “EmgDismiss.” 2.
MM23772, Rev. B 7.27.1 Automatic Encryption For automatic encryption, a system administrator will select the talk group to be encrypted at the interface to the UAS. Once the talk groups have been selected and identified as secure, credentials for key generation are generated automatically by the system and provisioned to authorized users. This process requires that authorized users login to the network and be authenticated.
MM23772, Rev. B 7.28 DYNAMIC REGROUPING Dynamic regrouping requires that the network administrator determine which radio users should be formed into an impromptu talk group to respond to particular emergency conditions. The administrator will edit the personalities of the affected radios to include an emergency profile and then page the affected radios to re-register with the network to receive their edited personalities.
MM23772, Rev. B 8 EDACS OPERATION 8.1 TURNING ON THE RADIO 1. Power ON the radio by rotating the POWER ON-OFF/VOLUME knob clockwise. A short alert signal (if enabled through programming) indicates the radio is ready to use. Refer to Figure 8-1 for location of the POWER ON-OFF/VOLUME KNOB. 2.
