Testing Mode
Once on, when the power button is
pressed for a long time, the RAM-L enters
a mode for system testing. This special
mode is intended for system debugging
and testing. When the RAM-L is turned
off, the special mode is reset. Upon
restarting the RAM-L the current standard
settings stored by GLM software are
restored.
Test mode selection blinks the power
button light (see Table 2). A special mode
is activated by a long press on the power
button. In a special mode the power button
light remains on but blinks off 1-4 times
indicating the mode currently selected.
The testing modes are not intended for
continued operation. Use GLM software to
set up permanent settings for 1238DF.
Safety Considerations
The 1238DF has been designed in
accordance with international safety
standards. To ensure continued safe
operation and to maintain the monitor
