50 Watt Trunk Amp (120-1970) Operation Faxback Doc. # 6648 TURNING ON THE AMPLIFIER The amplifier automatically turns on whenever you turn on your stereo system. The POWER indicator lights when the amplifier is on. SETTING THE INPUT LEVEL CONTROL LEVEL lets you adjust the level of audio signals that enter the amplifier. For the best performance, follow these steps to adjust the input level. 1. Turn LEVEL fully counterclockwise. 2. Turn on your stereo system and turn up the volume to about one-third of its full range. Turn on the ignition, if necessary, to turn on the amplifier. 3. Adjust LEVEL until the volume is at the maximum desired level. 4. Adjust the stereo system's volume control to a comfortable listening level. Cautions: Never turn LEVEL up any farther than you need to get clear sound at 2/3 volume. The sound distorts if any output channel shorts. Turn off the amplifier and try to locate the short. LISTENING SAFETY Do not listen at extremely high volume levels. Extended, high-volume listening can lead to permanent hearing loss. To protect your hearing, follow these guidelines. * Always start by setting the volume to the lowest level possible before you begin listening then gradually increase the volume as necessary. * Once you set the volume, do not increase it. Over a period of time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing. (LB/all-06/28/94)
