parts. It is essential to ensure that the subsequent safety rules are strictly observed:
• Servicing of electronic equipment must be performed by qualied personnel only.
• Before removing covers the equipment has to be switched off and the mains cable unplugged.
• When the equipment is open the power supply capacitors have to be discharged by the help
of a suitable resistor.
• During servicing unprotected and operating equipment:
- never touch bare wires or circuitry;
- use insulated tools only;
- never touch metal semiconductor cases because they may carry high voltages;
• For removing and installing electronic components, please follow the recommendations
concerning the handling of MOS components.

OPERATING ENVIRONMENT RECOMMENDATIONS
For the normal and reliable operation of the DB8000 device we recommend to follow the next
list of instructions:
• Please, install the unit only in places with good air conditioning. The unit has been designed
for operation within an ambient temperature range extending from 10 to 60°C. But because
adjacent, less efcient equipment may radiate substantial second-hand heat, be sure that the
equipment rack is adequately ventilated to keep its internal temperature below the specied
maximum ambient temperature.
• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions.
• Although it is expected that DB8000 will be installed close to exciters (or transmitters of
even higher-power!), please practice reasonable care and common sense in locating the unit
away from abnormally high RF elds.
• Please, use only already checked power supply cables and sources. The shielded cables
usage is strongly recommended.
• We strongly recommend connecting the device only to reliable power supply sources.
• In case of unstable power supply, please use UPS (Uninterruptible Power Supply).
• Please, use the device only with placed top cover to avoid any electromagnetic anomalies
which may cause problems of the normal functionality of the unit.
• Please, connect DB4000 only to good quality Internet connection. This is very important for
the normal remote operation of the unit.
• Please, check if your network settings pass through all the data trafc required for the
normal operation of DB8000 unit.
