(12) Rotate TI FUNCTION switch to 156-174 position. Using keyboard set TI to
160 MHz. Set AMR RF Tuning to 160.000.
(13) Toggle TI MOD LEVEL HI/LO switch until TI displays 70% AM. If AMR Freq
1000 Hz Modulation box indication is not 70% 5%, perform b (19) through (27) below.
(14) Toggle TI MOD LEVEL HI/LO switch to several different levels. If AMR Freq
1000 Hz Modulation box does not indicate within 5% of TI indication, perform b (28)
through (36) below.
(15) Rotate TI FUNCTION switch to 225-400 position. Using keyboard set TI to
300 MHz. Set AMR RF Tuning to 300.000.
(16) Toggle TI MOD LEVEL HI/LO switch until TI displays 70% AM. If AMR Freq
1000 Hz Modulation box indication is not 70% 5%, perform b (28) through (36) below.
(17) Toggle TI MOD LEVEL HI/LO switch to several different levels. If AMR Freq
1000 Hz Modulation box does not indicate within 5% of TI indication, perform b (37)
through (45) below.
(18) Rotate TI FUNCTION switch to 29-88 position and TONES switch to 150
position. Using keyboard set TI to 59 MHz. Set AMR RF Tuning to 59.000.
(19) Repeat technique of (4) through (18) above at 150 Hz tone using AMR Freq 150
Modulation box indications.
(20) Set PSA to Release, leave TI ANTENNA connected to measuring receiver and
set TI switches as listed in (a) through (e) below:
FUNCTION to 29-88.
(a)
(b)
Use keyboard to set TI to 59 MHz.
AM/FM to FM.
(c)
TONES to 1000.
(d)
Toggle MOD LEVEL HI/LO down until TI displays 8 KHz FM.
(e)
(21) Configure measuring receiver for FM measurement. Set HP filter to 300 Hz, LP
filter to 3 kHz and detector to Peak /2.
(22) If measuring receiver indication is not within 2 kHz modulation for the 1000
Tone switch setting, perform b (46) through (54) below.
(23) Toggle TI MOD LEVEL HI/LO switch to several different levels. If measuring
receiver does not indicate within 2 kHz of TI indication, perform b (46) through (54) below.
(24) Rotate TI FUNCTION switch to 108-118 position. Using keyboard set TI to
113 MHz.
(25) Toggle MOD LEVEL HI/LO down until TI displays 8 KHz FM. If measuring
receiver indication is not within 2 kHz modulation for the 1000 Tone switch setting,
perform b (55) through (63) below.
(26) Toggle TI MOD LEVEL HI/LO switch to several different levels. If measuring
receiver does not indicate within 2 kHz of TI indication, perform b (55) through (63) below.
(27) Rotate TI FUNCTION switch to 118-156 position. Using keyboard set TI to
137 MHz.
