THANK YOU FOR USING THIS MIDAS PRODUCT
To obtain maximum performance from this precision electronic product, please

complicated but the flexibility provided by its operating features merits familiari-
sation with its controls and connections. This unit has been prepared to comply
with the power supply requirements that exist in your location.
Precautions
Do not install this unit in a location subjected to excessive heat, dust or
mechanical vibration. Before connecting the unit to the mains power, ensure that
the operating voltage is correct for your local supply. It is important that you
observe the following instructions if another voltage setting is required:
Voltage Selection and Power Connection
Connection is made by means of an IEC standard power socket. The rear panel
voltage label indicates the voltage required for satisfactory operation of the unit.
Before connecting this unit to the mains supply, ensure that the fuse fitted is the
correct type and rating as indicated on the rear panel adjacent to the fuse holder.
To change the mains voltage please refer to the Voltage Changeover
section on page 24.
* Mains voltage adjustment should be carried out by a qualified service technician

Safety Warning
This unit is fitted with a 3-pin power socket: For safety reasons the earth lead
should not be disconnected. If you encounter a problem with earth loops, the
ground-lift link located inside the unit should be removed to isolate the signal
earth from the chassis earth (see page 23). Grounding problems should not
normally be encountered with the XL88. All pin 1s are commoned but not
connected directly to earth. Should any problems be encountered they will be
caused by the commoning of the grounds of the other equipment connected to the
XL88.
To prevent shock or fire hazard, do not expose the unit to rain or moisture.
To avoid electrical shock, do not remove covers. Refer servicing to qualified
personnel only.
