Taking Care of Your PortaTone Your PortaTone will give you years of playing pleasure if you follow the simple rules given below: I Location I Power Supply I Turn Power OFF When Making Connections I Handling and Transport I Cleaning Do not expose the instrument to the following conditions to avoid deformation, discoloration, or more serious damage. G Direct sunlight (e.g. near a window). G High temperatures (e.g. near a heat source, outside, or in a car during the daytime). G Excessive humidity. G Excessive dust. G Strong vibration. G Turn the power switch OFF when the instrument is not in use. G The power supply cord should be unplugged from the AC outlet if the instrument is not to be used for an extended period of time. G Unplug the instrument during electric storms. G Avoid plugging the instrument into the same AC outlet as appliances with high power consumption, such as electric heaters or ovens. Also avoid using multi-plug adapters since these can result in reduced sound quality, operation errors, and possibly damage. G To avoid damage to the instrument and other devices to which it is connected (a sound system, for example), turn the power switches of all related devices OFF prior to connecting or disconnecting audio and MIDI cables. G Never apply excessive force to the controls, connectors or other parts of the instrument. G Always unplug cables by gripping the plug firmly, not by pulling on the cable. G Disconnect all cables before moving the instrument. G Physical shocks caused by dropping, bumping, or placing heavy objects on the instrument can result in scratches and more serious damage. G Clean the cabinet and panel with a dry soft cloth. G A slightly damp cloth may be used to remove stubborn grime and dirt. G Never use cleaners such as alcohol or thinner. G Avoid placing vinyl objects on top of the instrument (vinyl can stick to and discolor the surface). 4
