TeachLogic
®
Matrix™ (IMA-121 and IMA-120) amplifiers
have a standby (or sleep) energy saving mode that
causes the amplifier to enter a standby mode
after two
hours
without audio activity. At this point, the CPS-121
control panel display will go dark (not just dim) and it will
repeat the word “Standby” on the display every minute.
The panel is still powered, however, and will respond to
the command to change the amplifier power mode to ON
(or wake the amplifier).
Using Control Panel Buttons
Press any button to activate the control panel. If the panel display is dim, the panel is not active and
pressing any button is required. When a button is pressed, the screen will brighten. Once the screen is
bright, the panel is active.
