UNPACKING AND INSPECTION
Upon receipt, the equipment should be inspected for possible shipping damages. If such are
found or suspected, notify the carrier at once and contact DEVA Broadcast Ltd. The original
shipping carton box and packing materials should be kept for possible reuse, in case of return for
Warranty repair, for example. Shipping damages as a result of improper packing for return may
invalidate the Warranty!
IT IS VERY IMPORTANT that the “Product Registration Card” included in the Manual be
completed accurately and returned. This will assure coverage of the terms of the Warranty and it will
provide a means of trace in case of lost or stolen equipment. In addition, the user will automatically
receive SERVICE OR MODIFICATION INSTRUCTIONS from DEVA Broadcast Ltd.
RADIO FREQUENCY INTERFERENCE
Although we have made provision for DB3010 installation in the immediate proximity of
broadcast transmitters, please do practice some care using the unit near abnormally high RF elds.

Mounting
RACK REQUIREMENTS
The DB3010 mounts in a standard 19-inch equipment rack and requires only 1¾ inches (1U) of
vertical rack space. In order the painted nish around the mounting holes to be protected, the use
of plastic washers is recommended.
HEAT DISSIPATION
Having very low electricity consumption, the DB3010 itself generates negligible heat. The
unit is intended for operation within an ambient temperature range, extending from freezing to
120°F/50°C. But because adjacent, less efcient equipment may radiate substantial heat, be sure
that the equipment rack is adequately ventilated to keep its internal temperature below the specied
maximum ambient.

AC Mains Power
FUSE HOLDER
The fuse holder is placed inside the unit, next to the voltage selector. Apply downward pressure
and pull the cap outward to access the 5mm mains fuse. The reverse process will release the cap.
MAINS VOLTAGE SELECTOR
Before connecting the AC Power, make sure that the internal Power Switch and the fuse rating
are in accordance with the mains supply at your location.
DB3010 Power Supply Factory Settings are:
- 100 - 240 VAC
- 1 Amp Fuse
CAUTION: Permanent damage will result if improper AC supply voltage is applied to DB3010
device. Your warranty does not cover damages caused by applying improper supply voltage, or use
of an improper fuse.
POWER CORD
The detachable IEC-type power cord is supplied with the unit. The individual cord conductors
may be color-coded in either of two ways:
1) In accordance with US standards:
BLACK = AC “HOT”
WHITE = AC NEUTRAL
GREEN = EARTH GROUND
2) To European CEE standards:
BROWN = AC “HOT”
BLUE = AC NEUTRAL
GREEN/YELLOW = EARTH GROUND
GROUND LOOPS
Because the unbalanced RF INPUT of the DB3010 is chassis-ground-referenced, a mains
frequency or RF ground loop could be formed between the input or output cable shield grounds
and the AC power cord ground. A ‘ground-lifting’ AC adapter may well remedy such a situation,
although the chassis somehow must be returned to earth ground for safety. Generally, being
screwed-down in the equipment rack will satisfy the safety requirement.

Basic Setup
OLED DISPLAY
DB3010 has an easy to read, high-resolution OLED graphical display that visualizes all
measurements of the received signal and settings. Upon switching it on, the Company Logo and
model of the device will be displayed. After a few seconds the start-up screen will disappear,
replaced by the main screen. This is the starting point of the navigation process.
DB3010’s OLED display has three function areas: header, soft buttons and main screen working
area.
HOW TO CHANGE DEVICE PARAMETERS
Set-up menu title
Shows the path to the currently selected menu. Note that the parameter should be included in
the settings menu title. For example: Setup> Communication> HTTP> Port is different from
Setup> Communication> FTP> Data Port.
Navigation area
Selection of branches / parameters is made in this area. The selected item is highlighted. All
parameters are listed on the left side of the navigational area. All parameter values are displayed
