1. 2 Set your Stryker radio to your desired operating freguency or the center of the range of freguencies you plan to use Press the PTT Press To Talk switch and tap the antenna making it shorter The SWR meter will show a lower reading each time the antenna is tapped By continuing to shorten the antenna you will notice the SWR reading will reach a low point and then start rising again This means that you have passed the optimum point for the middle freguency 3 Extend the antenna a short distance and again follow the procedure above 4 When the lowest point has been reached switch to the lowest freguency you plan to operate on and then to the highest and compare SWR readings They should be almost egual B Antennas that must be cut to proper length 1 Follow the procedure as in A above but adjust the length by cutting in 18 increments until a good match is obtained 2 Be very careful not to cut too much off the antenna at one time Once it is cut it can no longer be lengthened 3 The whip is easily cut by filing a notch all the way around then breaking the piece off with pliers NOTE The proper setting is achieved when the SWR is 1 5 or below and when it has the same reading for the low and high freguencies in the range you plan to use External Speaker The external speaker jack EXT on the rear panel is used for remote receiver monitoring The external speaker should have 8 ohms impedance and be able to hand2. 16 beyond the plastic insulating jacket of the microphone cable 2 All leads should be cut to the same length Strip the ends of each wire 1 8 and tin the exposed wire Before beginning the actual wiring read carefully the circuit and wiring information provided with the microphone you select Use the minimum heat required in soldering the connections Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled KNURLED RING HOUSING gt lt Vr CI SI HAN fj lol 2 he vo W OWN 9 2 z a 4 A PIN RECEPTACLE i RETAINING SCREW CABLE ELAME RETAINER SCREW 2 A MICROPHONE CONNECTOR ASSEMBLY HO S a B MICROPHONE CONNECTOR DISASSEMBLED FOR WIRING WASHER Z Fig 2 Microphone plug wiring To wire the microphone cable to the plug provided proceed as follows 1 Remove the retaining screw 2 Unscrew the housing from the pin receptacle body 3 Loosen the two cable clamp retainer screws 4 Feed the microphone cable through the housing knurled ring and washer as shown Figure 2 Function Menu Navigation The function menu allows you to customize many features as well as controls that your Stryker SR 955HP has to offer To access the function menu press and hold the FUNC Button for approximately two seconds until the LCD meter disp
