Operation
IMPORTANT: Before plugging the amplifier into an AC outlet, turn all volume controls to their full counterclockwise positions and all other controls to their reference position.
Indicator
PEAK LEVEL The PEAK LEVEL LED illuminates whenever the speaker output signal level approaches its maximum level. This indicator is used when setting volume levels. Maximum output level is achieved when the PEAK LEVEL indicator flashes intermittently on loud peaks of the input signal. If the indicator illuminates steadily, the output signal volume is set too high and distortion is occurring. Decrease the volume control for the appropriate input until the indicator flashes only intermittently.
Controls
PAGE VOLUME This control adjusts the level of the telephone page output. A reference level setting position is provided with this control. When set to this position, the output level of the page should be optimally loud without distortion. Further adjustment can be made using the PEAK LEVEL indicator, as described above.
MUSIC VOLUME This control adjusts the level of the background music output. No reference level setting position is provided. The background music level should be set to an acceptable level without overdriving the system. When adjusting this level, use the PEAK LEVEL indicator, as described above.
NIGHT BELL This control adjusts the level of the night bell tone output. No reference level setting position is provided. The night bell level should be set to the customer's satisfaction. When adjusting this level, the PEAK LEVEL indicator should be used to ensure that the amplifier signal is not distorted.
TONE Use the TONE control to optimize the tonal balance of the amplifier output.
