1. Safety Precautions
• Do not drop the DR 52 BA and do not expose it to liquid, mois-
ture or humidity. These might lead to damage to the device.
• If the DR 52 BA is moved from a cold environment into a warm-
er one, do let it adapt to the new temperature before operating
the device. Otherwise it might lead to condensation and cause
malfunctions in the device.
• Do not use the DR 52 BA in a dusty environment as dust can
damage the interior electronic components and lead to malfunc-
tions in the device.
• Do not attempt to disassemble the DR 52 BA.
• Only use the power adaptor delivered with the DR 52 BA.
• Never touch the power plug with wet hands and never pull on
the power cable when pulling the plug out of the power socket.
• Make sure the electrical voltage specified on the DR 52 BA
and its power plug is corresponding to the voltage of the power
socket. Incorrect voltage will destroy the device.
• If the DR 52 BA is not used for a long period of time, disconnect
it from the power supply by unplugging the power plug. This is to
avoid the risk of fire.
• Always power off the DR 52 BA when cleaning it.
• Never use any harsh or strong solvents to clean the
DR 52 BA since these may damage the surface of the device.
Dry, soft cloth is appropriate; however, if the DR 52 BA is ex-
tremely dirty, it may be wiped off with a slightly moist cloth. Make
sure the device is dried off after cleaning.
• When you have to ship the DR 52 BA, store it in its original
package. Save the package for this purpose.
• If you have to dispose the device in the future, note that it
should not be disposed with household waste. Bring it to a re-
ception point for the recycling of electrical devices. Consult your
local authority or retailer for recycling advice.
