AMX MVP-9000i, Operation And Reference Manual, Page: 20 / 202

Introduction
6 MVP-9000i 9" Modero® ViewPoint® Touch Panel with Intercom
When not in active use, the MVP-9000i conserves battery life between chargings. Pressing the touch screen will return
the device to its On Mode. For more information on the battery, see the
Battery Life and Replacement section on
page 163.
Cleaning the Touch Overlay and Case
Always use a clean cotton cloth and a spray bottle containing water or any standard ammonia-free glass cleaner can be
used to clean the touch screen. Do NOT use alcohol-based cleaners, as alcohol-based cleaners can damage the device’s
touch screen overlay.

Do not directly spray the device : instead, spray the cloth to clean the touch screen overlay.

Do NOT use an abrasive of any type to clean the MVP-9000i, as this may permanently damage or remove the
device’s finish.
Charging Lithium Polymer batteries at high temperature will reduce the battery life.
Industry guidelines dictate that batteries should not be charged at temperatures
above 45° C (113° F). The temperature is determined by a combination of the
ambient temperature where the panel is located, plus temperature increases
normally occurring inside electronic devices containing batteries. AMX has
implemented battery temperature monitoring features to maximize the rate of battery
charging, while staying within industry temperature guidelines.
Battery charge times will increase in installations where the room temperature is
above 25° C (77° F), and may be temporarily suspended at room temperatures
above 30° C (86° F). Battery charging will automatically resume once the
temperature has fallen to appropriate levels. Minimizing the display backlight intensity
and turning off the backlight during periods of non-use will also yield faster charge
times.
Although the MVP-9000i unit is equipped with a mini-USB port, the device cannot be
powered through the USB port. The port is only used for uploading firmware.
