SAFETY INSTRUCTIONS
This chapter contains important safety instructions that
you must follow when operating GSP-830 and when
keeping it in storage. Read the following before any
operation to insure your safety and to keep the best
condition for GSP-830.
Safety Symbols
These safety symbols may appear in this manual or on GSP-830.
WARNING
Warning: Identifies conditions or practices that could
result in injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that could
result in damage to GSP-830 or to other properties.
DANGER High Voltage
Attention Refer to the Manual
Protective Conductor Terminal
Earth (ground) Terminal

Safety Guidelines
•Make sure that the RF input level and the Tracking
Generator output reversed power level do not exceed
+30dBm.
•Do not supply an input signal to the Tracking
Generator output.
•Do not place any heavy object on GSP-830.
•Avoid severe impacts or rough handling that leads to
damaging GSP-830.
•Do not discharge static electricity to GSP-830.
•Use only mating connectors, not bare wires, for the
terminals.
•Do not block or obstruct the cooling fan vent opening.
•Do not perform measurement at power source and
building installation site (Note below).
•Do not disassemble GSP-830 unless you are qualified
as service personnel.
General Guideline
CAUTION
(Note) EN 61010-1:2001 specifies the measurement categories and
their requirements as follows. GSP-830 falls under category II.
•Measurement category IV is for measurement performed at the
source of low-voltage installation.
•Measurement category III is for measurement performed in the
building installation.
•Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
Power Supply
WARNING
•AC Input voltage: 100 ~ 240 V AC, 50/60Hz
•DC Input voltage: 12V DC, 40W maximum
•The power supply voltage should not fluctuate more
than 10%.
•Connect the protective grounding conductor of the
AC power cord to an earth ground, to avoid electrical
shock.
Battery
CAUTION
•Rating: 10.8V Li-Ion battery pack x 2
•Turn Off the main power switch before installing or
taking out the battery packs.

Fuse
WARNING
•Fuse type: T1.6A/ 250V
•Make sure the correct type of fuse is installed before
power up.
•To ensure fire protection, replace the fuse only with
the specified type and rating.
•Disconnect the power cord before fuse replacement.
•Make sure the cause of fuse blowout is fixed before
fuse replacement.
Cleaning GSP-830 •Disconnect the power cord before cleaning.
•Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid into
GSP-830.
•Do not use chemical or cleaner containing harsh
material such as benzene, toluene, xylene, and acetone.
•Location: Indoor, no direct sunlight, dust free, almost
non-conductive pollution (Note below)
•Relative Humidity: < 90%
•Altitude: < 2000m
•Temperature: 18°C to 28°C
Operation Environment
(Note) EN 61010-1:2001 specifies the pollution degrees and their
requirements as follows. GSP-830 falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
•Pollution degree 1: No pollution or only dry, non-conductive pollution
occurs. The pollution has no influence.
•Pollution degree 2: Normally only non-conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by
condensation must be expected.
•Pollution degree 3: Conductive pollution occurs, or dry,
non-conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment is
normally protected against exposure to direct sunlight, precipitation,
and full wind pressure, but neither temperature nor humidity is
controlled.
Storage Environment •Location: Indoor
•Relative Humidity: < 85%
•Temperature: 0°C to 40°C

Power cord for the United Kingdom
When using GSP-830 in the United Kingdom, make sure the power cord
meets the following safety instructions.
NOTE: This lead / appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the
colours marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with the letter E or by the earth symbol or coloured Green
or Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked
with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact
the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or
user instructions for details. As a guide, cable of 0.75mm2 should be
protected by a 3A or 5A fuse. Larger conductors would normally require 13A
types, depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately,
as a plug with bared wires is hazardous if a engaged in live socket. Any
re-wiring must be carried out in accordance with the information detailed on
this label.
