If a new antenna was installed with the radio, use the following adjustment procedure to obtain optimum radio and antenna reception sensitivity. If the antenna is a telescoping type, extend it fully. Turn the ignition switch to the ACC position. Turn on the radio and set it to the AM range. Select a weak station in the 1,400 khz range. If no station exists in that range, use static to make the adjustment. Turn the antenna trim adjustment screw to the left and right to find the maximum sensitivity. If the sensitivity does not change, there is either a problem with the antenna, a broken wire, or the signal is too strong.
