Routine maintenance
82 DEFINITY ECS Console Operations
To test the display and lamps on a 302C/D console:
1. Press and hold the
POS BUSY and VOLUME UP button simultaneously. The
following occurs repeatedly:
■ All segments in the display turn on for several seconds while the top
row of lamps cycle on and off.
■ The 302D displays the console type, firmware release, and release
date.
■ Each row of lamps on the console and the selector console cycle on
and off in sequence from top to bottom.
■ The timed-reminder tone (high-pitched, 0.5 second tone) sounds.
2. Release the
POS BUSY and VOLUME buttons.
■ Lamps return to their former state.
■ The timed-reminder tone silences.
3. If needed, press
POS BUSY to return to normal mode.
Cleaning the console
To clean the console, use a slightly-dampened paper towel or soft cloth. Oily
substances on the console may require considerable rubbing or the use of a mild
cleaner, such as window cleaner or desk and office cleaner. If you use a cleaner,
do not apply it directly to the console; instead, apply it to the cloth, then rub it
onto the console.
Do not spill any type of liquid on the console. Liquids spilled on the console
damage the electronic components.
