CHANGING LIMITER RELEASE TIME TO ONE SECONDRemove resistor R741 (about 15 mm behind ribbon cableassembly W813).CHANGING LIMITER THRESHOLD PRESETS1. Select the equivalent resistor values for the desired limiterthresholds from the following table. Then fill in the followingwork sheet with the resistor selections.Limiter Threshold(dBm into 600 Ω)R equiv(kΩ)Limiter Threshold (dBm into 600 Ω)R equiv(kΩ)0 18 10 811 21 11 932 25 12 1053 30 13 1224 35 14 1395 41 15 1566 47 16 1757 54 17 1948 62 18 2159 71DIP Switch S701 Limiter Threshold R equiv (above)Position 2 Position 3–dBm –up up high _____ kΩ = R1down up med. high _____ kΩ = R2up down med. low _____ kΩ = R3down down low _____ kΩ = R42. Remove resistors R721, R731, R732, R733, R734 and R735(surrounding IC U704).3. Locate empty pads X732, X733, X734 and X735 (surroundingIC U704).4. Select a 1/4 W, 1% resistor closest in value to R1 (from thework sheet), and solder it to the holes of X732.Note: Use parallel or series combinations of resistors to matchthe chosen values as closely as possible if 1% resistors are notavailable.5. Calculate resistor R5 value as follows:R5 =11R2 – 1R1Select a 1/4 W, 1% resistor closest in value to R5 and solder itto the holes of X733.6. Calculate resistor R6 value as follows:Select a 1/4 W, 1% resistor closest in value to R6 and solder itto the holes of X734.7. Calculate resistor R7 value as follows:Select a 1/4 W, 1% resistor closest in value to R7 and solder itto the holes of X735.
