(14) Disconnect 10 foot cable from measuring receiver and connect it to TI
ANTENNA port.
(15) Press TI ENT then 4 (RxRamp) key on keypad.
(16) Verify TI indicates between 21 and 29 W. If TI does not indicate within limits
specified increase or decrease the VAL= value for a 25 W indication.
(17) Repeat steps technique of (12) through (14) above for remaining values in
table 15 below.
NOTE
The left / right keys will change frequencies within selected mode.
(18) Skip the MB, LOC, VOR, and ILS modes.
