GENERAL INSTRUCTIONS
Observe the following safety precautions when handling this unit. This equipment operates with
dangerous voltages and currents.
•
All electrical installations and connections are to be carried out only by skilled personnel.
•
When outfitting operating rooms as well as setting up and operating electrical equipment follow the
relevant national and international safety instructions and regulation.
•
When setting up the rack observe the relevant safety precautions for the prevention of accidents.
These precautions especially relate to: danger of getting crushed when working with loads, danger of
falling off ladders while working, danger of getting hurt or injured when lifting heavy loads.
•
Always disconnect power before opening covers or removing any part or module of this transmitter
unit.
•
Prior to checking out or working on the switch mode supply, disconnect all the R.F. power amplifiers.
•
Some of the R.F. power amplifier transistors are encased in Beryllium Oxide (BeO). This substance is
harmless as is, but becomes very dangerous if ground to a powder. These devices, once failed,
cannot be disposed of by normal means and special procedures of disposal must be observed.

Voltage values Vrms > 30V AC or V > 60V DC are potential hazard. Take appropriate measures to
avoid any danger when working with hazardous voltages.
Never work on live parts. It is only permissible to work on live parts under exceptional circumstance and
if special safety precautions have been taken.

Prior to connecting power supply ensure that the AC line data on the product matches the data of the
available supply. Fuses or other devices in the supply circuit must guarantee overload and short-circuit
protection.
The user is responsible for correct fuse protection.
