Vector-LP Radio Beacon Transmitter Technical Instruction Manual Page 3-23Section 3 Operating Instructions Issue 1.1(e) Use and to highlight the desiredmonitor timeout field and press Modify: The low limit is factory set for 3.00 dB.Adjust using and . The high limit is factory set for 2.00 dB.Adjust using and .(f) Press Back, highlight Automatic Resetand press Select.(g) Use and to highlight the desiredFault 1 -5 field and press Modify. Set theAutomatic Reset schedule as follows:NOTEThe Automatic Reset allows the user todefine a reset schedule for the transmitterafter a shutdown condition. The schedule canhave up to five sequential levels, each withtheir own user definable delay period (up to24 hours) and subsequent instruction. ENABLED (continue): attempts a resetthe denoted delay time after a shutdownand then, if no reset occurs, continues tothe next item in the Fault schedule. ENABLED (repeat): attempt a reset thedenoted delay time after a shutdown andcontinues attempting (as necessary) aftereach delay time. All subsequent items inthe Fault schedule default to DISABLED. ENABLED (halt): attempts a reset thedenoted delay time after a shutdown andthen, if no reset occurs, stops attempting.All subsequent items in the Faultschedule default to DISABLED. DISABLED: no attempt to reset. Waits the Fault 1 delay period (40 min) Attempts to reset transmitter. Ifsuccessful, Automatic Reset schedulewill begin on Fault 1 next shutdown. Ifunsuccessful, reset sequence continuesto Fault 2 item. Waits the Fault 2 delay period (20 min) Attempts to reset transmitter. Ifsuccessful, Automatic Reset schedulewill begin on Fault 1 next shutdown. Ifunsuccessful, repeats Fault 2 item.(h) Press Back, highlight Mod% Thresholdsand press Select. The following messageis displayed. Press Continue to proceed.NOTEAs the warning message indicates, ensurethat the transmitter is operating at theminimum allowable modulation depth beforecomputing the thresholds. If the transmitter isto operate in both PTT and Normal modes,set up both thresholds, otherwise, set up onlythe applicable threshold.(i) The screen shows the minimumallowable modulation for PTT Inactive(no voice) and PTT Active (voice). The left column has side A values andthe right column has side B values.-Before proceeding, make sure that youhave set the ident tone to the minimumacceptable modulation depth with PTTinactive, and again with PTT active.-If this is a dual system, ensure tonehas been set correctly on both sides.Continue Back12:43:16 Power: 0W Side A Bypass-Before proceeding, make sure that youhave set the ident tone to the minimumacceptable modulation depth with PTTinactive, and again with PTT active.-If this is a dual system, ensure tonehas been set correctly on both sides.Continue Back12:43:16 Power: 0W Side A Bypass12:43:16 Power: 0W Side A BypassMod % ThresholdsMinimum Allowable Tone Modulation Depth:...PTT Inactive: 164 153...PTT Active: 1023 102363.8 63.835.4 35.4Compute NewThresholdsRf Mon: CURRToggle Back12:43:16 Power: 0W Side A BypassMod % ThresholdsMinimum Allowable Tone Modulation Depth:...PTT Inactive: 164 153...PTT Active: 1023 102363.8 63.835.4 35.4Compute NewThresholdsRf Mon: CURRToggle Back12:43:16 Power: 0W Side A BypassMod % ThresholdsMinimum Allowable Tone Modulation Depth:...PTT Inactive: 164 153...PTT Active: 1023 102363.8 63.835.4 35.4Compute NewThresholdsRf Mon: CURRToggle Back12:43:16 Power: 0W Side A BypassSide A Side BMain Menu Modify Back12:43:16 Power: 0W Side A BypassAutomatic ResetFault 1 ENABLED (continue) Delay 00:40Fault 2 ENABLED (repeat) Delay 00:20Fault 3 DISABLEDFault 4 DISABLEDFault 5 DISABLEDMain Menu Modify Back12:43:16 Power: 0W Side A Bypass12:43:16 Power: 0W Side A BypassAutomatic ResetFault 1 ENABLED (continue) Delay 00:40Fault 2 ENABLED (repeat) Delay 00:20Fault 3 DISABLEDFault 4 DISABLEDFault 5 DISABLED
