Power switch

The Martin Audio Engineer 418 has a power switch which is accessible through the hole in the front panel

(please refer to the front panel layout). Although the device is designed to be left on at all times, it is possible

to un-power the device with this switch. To switch ON/OFF, use a Philips #1 screwdriver to operate the power

switch through the hole.

Warning: Since the mains power plug can be used as the main disconnection device, care must be must be

taken during installation that this plug is made easily accessible at all times.

Power LED

The blue power LED shows the status of the isolated 5V power supply to the digital circuits. When lit, this

power supply is active.

Note that the other internal power supply circuits do not have an external or internal status indicator.

RS-232 front panel cover

When the RS-232 port on the front of the device is not used, the RS-232 port may be covered with the supplied

RS-232 front panel cover. Use the two supplied screws to attach the cover to the front panel. These screws

have holes drilled through the heads which may be used to seal the RS-232 port so unwanted operation is

prohibited.
