Pharmacovigilance plan

Set/View options are global and do not pertain to any individual channel, but to the entire range of channels and presets. Changing these options permits the operator to make necessary changes while operating and remaining online, rather than entering programming which makes the radio go offline. When the radio is offline, the operator cannot receive a call.

3.15.1 Set Transmit Power

Power level depends on power amplifiers and whether the radio is in HF or VHF as described in Table 3-7.

See Figure 3-8. Perform the following procedure to set transmit power level:

a. Choose OPT>RADIO>TX POWER menu choices. Current power level is displayed.

b. Use the keys to scroll through the settings (LOW, MED, HIGH).

c. Press [ENT] for desired power level and advance to the next screen.

d. To exit, press [CLR] several times or press [OPT].

3.15.2 Set Squelch Level

Squelch level choices consist of low, medium, or high. A squelch level of low may cause false squelch breaks to occur while settings of medium or high may not allow AN/PRC-150(C) to unsquelch on weak signals.

See Figure 3-8. Perform the following procedure to set squelch level:

a. Choose OPT>RADIO>SQUELCH LEVEL menu choices. Radio’s current squelch level is displayed.

b. Use the to scroll to the desired squelch level and press [ENT].

c. To exit, press [CLR] several times or press [OPT].

3.15.3 FM Squelch Type

The AN/PRC-150(C) supports analog tone squelch and analog noise squelch. Analog tone squelch requires that a 150 Hz tone be transmitted along with the normal radio traffic in order to open the receive radio’s squelch. Analog noise squelch requires a signal that is strong enough to open the AN/PRC-150(C)’s squelch being received on the AN/PRC-150(C)’s receive frequency. This is important for interoperability and should be addressed during mission planning. Most users of VHF-FM radios use tone squelch.

See Figure 3-8. Perform the following procedure to set squelch level:

a. Choose OPT>RADIO>FM SQUELCH TYPE menu choices. Radio’s current squelch type is displayed.

b. Use the to scroll to the desired squelch type and press [ENT].

c. To exit, press [CLR] several times or press [OPT].

3.15.4 Bypass/Enable Internal Coupler

The internal coupler should be enabled to allow a resonant or field expedient antenna to be used at any frequency.

The internal coupler must be disabled during wideband and list frequency hopping. Otherwise, a hopping error may occur at some frequencies. When the coupler is disabled, a broadband antenna should be used for maximum performance and VSWR should be measured, as described in Paragraph 3.5.4. See Figure 3-8. To bypass/enable the internal coupler, perform the following:

a. Choose OPT>RADIO>COUPLER menu choices. Current coupler setting is displayed.

b. Use the to scroll to the desired enable or bypass setting and press [ENT].

c. To exit, press [CLR] several times or press [OPT].

3.15.5 Set Radio Silence On or Off

The AN/PRC-150(C) silence option is used during ALE and 3G radio modes. This feature enables the operator to disable the AN/PRC-150(C) from automatically responding to an ALE or 3G call. This option is only enabled in receive and may be overridden if the operator places an ALE or 3G call. Radio Silence is not the same as Receive Only, which can be programmed into any radio mode. See Figure 3-8. Perform the following procedure to turn radio silence on or off:

a. Choose OPT>RADIO>RADIO SILENCE menu choices. Current radio silence setting is displayed.

b. Scroll to the desired on or off setting and press [ENT].

c. To exit, press [CLR] several times or press [OPT].

NOTE

If RADIO SILENCE is ON, the R in the upper left corner of the KDU flashes when the channel preset is viewed in ALE or 3G (instead of scanning). Also, upon entering radio silence, KDU light intensity is reduced to zero and the volume is decreased to a minimum. (The operator can still readjust, if desired.)

3.15.6 Set Beat Frequency Oscillator (BFO) Offset

See Figure 3-8. An offset may be required for communications with old radios whose time standards have drifted.

Some operators prefer to change the BFO for personal tone preferences during CW operation. Perform the following procedure to set BFO offset:

a. Choose OPT>RADIO menu choices.

b. Press [ENT] until BFO is displayed. The display will show the current BFO offset.

c. Use the to scroll until the desired BFO frequency is displayed and press [ENT]. BFO is adjustable +/- 4000 Hz in 10 Hz steps.

d. To exit, press [CLR] several times or press [OPT].

NOTE

The radio’s BFO setting will change as the frequency is scrolled. This enables the operator to have real time control over the adjustment prior to pressing [ENT].

3.15.7 Set RX Noise Blanking On or Off

The RX noise blanking is used to filter signals that are interfering with the intended receive signal. This filtering or blanking will also reduce the strength of the intended signal and should only be used if the intended signal is strong enough to overcome the filtering. See Figure 3-8. Perform the following procedure to set RX noise blanking:

a. Choose OPT>RADIO> menu choices.

b. Press [ENT] until RX NOISE BLANKING is displayed. Current RX noise blanking setting is displayed.

c. Use the to scroll until the desired ON/OFF setting is displayed and press [ENT].

d. To exit, press [CLR] several times or press [OPT].

3.15.8 Set CTI Autoreject On or Off

The AN/PRC-150(C) Computer Telephony Interface (CTI) autoreject option is used in radios deployed in a CTI capable 3G network. This feature enables the operator to have the AN/PRC-150(C) automatically reject any incoming CTI call. The radio will still respond to 3G calls and the operator will be able to place an outgoing CTI call.

NOTE

CTI autoreject is automatically set to ON, if CTI is disabled in the radio. Also, autoreject is automatically set to OFF on the basestation radio connected to an RF-6010. In either of these cases, the autoreject setting will not appear.

Perform the following procedure to turn CTI autoreject on or off:

a. Choose OPT>RADIO menu choices.

b. Press [ENT] until CTI AUTOREJECT is displayed.

c. Use the to scroll until the desired ON/OFF setting is displayed and press [ENT].

3.15.9 Check Radio Name

Radio name is used to report the radio name of the AN/PRC-150(C). This is used in programmed Automatic Repeat Request (ARQ) modem presets and in 3G radio mode. RADIO NAME is not modifiable in the options menu, but can be set during programming. Refer to Paragraph 4.5.1 for information about programming the radio name.

3.15.10 View GPS TOD

The GPS TOD screen allows the user to view the current state of the GPS, the current radio time, and if GPS is installed, the current or last known position information.

See Figure 3-9. Perform the following procedure to view the AN/PRC-150(C)’s TOD and GPS information:

a. Choose OPT>GPS-TOD menu choices. The first screen shows the GPS state of NOT INSTALLED, SEARCHING, or TRACKING.

In all cases, the current date/time is shown in the lower right-hand corner. SEARCHING means the GPS has not been acquired or has been lost. TRACKING means the GPS has acquired a valid signal.

When in SEARCHING or TRACKING, the number of GPS satellites currently being tracked is displayed in the lower left-hand corner.

NOTE

The AN/PRC-150(C) Time-Of-Day (TOD) must be set before attempting to use HOP, 3G, scheduled LQAs, or ALE Linking Protection. To modify the TOD, follow the procedure outlined in Paragraph 4.5.4.

b. View the individual items by pressing [ENT].

If GPS is not installed, pressing [ENT] will return the user to the OPT menu. Otherwise, if GPS is SEARHCING, the next screen will display the last date/time a valid GPS reading was taken. If GPS is TRACKING, the screen will be skipped.

Next, the radio’s last valid (or current if GPS is tracking) long/lat is displayed, followed by last known/current velocity, and then the last known/current altitude.

c. Press [CLR] or [ENT] to return to the option menu.

d. Press [OPT] to return to the preset screen.

NOTE

If the GPS is not connected, EXTERNAL GPS DISCONNECTED will display.

3.15.11 Retune Manpack (MP)

This function is used to force a retune of the coupler due to an antenna change or loss of tune condition. See Figure 3-9. Perform the following procedure to force a retune of the internal coupler in the MP:

a. Choose OPT>RETUNE menu choices. While the coupler is retuning, COUPLER TUNING IN PROGRESS is displayed at the bottom of the preset screen. When the coupler has completed tuning, COUPLER TUNING COMPLETE is displayed at the bottom of the preset screen.

NOTE
