Handles
– Two sturdy cast aluminium handles are integrated into the front panel. The handles should be used
when carrying the device, and when fitting into or removing from a rack. Ensure that any door or removable rack
front cover has sufficient depth to clear the handles.
2
Dust Filters
– Two dust filters are fitted behind metal covers. To remove the covers, loosen the thumbscrews
located behind the handles. Once detached, the dust filter elements can be removed for cleaning; please refer to
section 9.2 for further information.
NOTE: NEVER operate this device without the dust filters in place.

Display
– The display illuminates when the device is on, except when screen saver is active. The LCD,
function buttons, and the rotary encoder provide real-time control and monitoring of most parameters. The
LEDs embedded in the function buttons indicate available menu options, provide confirmation of Controller
communication, and indicate various faults and warnings. The display automatically returns to Home view if no
activity within two minutes.
The brightness and contrast of the display and front panel LEDs can be adjusted via the front panel menu. A
screensaver will turn off the display when the unit is left without any action or with very low power output signal for
30 minutes. It will light up again at the push of any button, when the Lake Controller communicates with any frame
or when signal reaches above -20 dB on any power output. Please refer to Section 7 for further details.

Standby
– PLM+ Series devices are powered on and to standby using the top-left button, or via the
Lake Controller.
