Safety and Manual Conventions Giga-tronics GT-1040A Microwave Power Amplifier
1.4 Electrical Safety Precautions
• Any servicing instructions are for use by service-trained personnel only. To avoid personal injury, do not
perform any service unless you are qualified to do so.
• For continued protection against fire hazard, replace the AC line fuse only with a fuse of the same current
rating and type. Do not use repaired fuses or short circuited fuse holders.
1.5 Important Operating Instructions
• The GT-1040A Amplifier does not include an enable/disable feature to activate and deactivate the amplifier.
When connecting or disconnecting the output of the amplifier, ensure that the power switch on the rear of
the amplifier is in the OFF position.
• When connecting the amplifier to a transmitting device, observe all safety procedures to ensure that the
amplifier isn’t interfering with other systems in the area. High power microwaves can adversely affect power
sensitive instruments in the area of transmission.
• Exercise precautions to avoid exposure to radiated microwave energy at all times.
