ATTENTION!
All DIGISYNTHETIC PRO products are carefully packed and designed to protect the units from rough handling
before shipping out from the factory. Examine your good upon receiving, to ensure no damage during transportation.
Any damage claim should be inform & notify to relative dealer within 14 days of good received. The dealer
will not except failing of such. The consignee must make all shipping claims.
The DS216 fits into a standard 19" rack unit of space (1 3/4"). Allow at least an additional 4" depth for the
connectors on the back panel. Be sure that there is enough air space around the unit for cooling and ventilation.
DO NOT place the DS216 on high temperature devices like power amplifiers etc. to avoid overheating.
Using a main cable and a standard IEC receptacle makes the main connection of the DS216. It meets all of the
international safety certification requirements.
Please make sure that all units have a proper ground connection. For your own safety, do not remove the ground
connection within the unit or at the supply, or fail to make this connection at all.
NOTICE: Before switching voltage for local supply requirement, correct fuse type and rate must be installed.
When the power supply is 220V/240V, fuse is 125mA; and the power supply is 110V/120V, fuse is changed
to 315mA. The switch is preseted to 220V/240V in the factory.
This machine is only intended for qualified personnel to operate & install. Do not attempt to repair and service
yourself but referred to qualified technical service personnel. The user must have sufficient electrical contact
to earth. Electrostatic charges might affect the operation of the DS216.
