FOR UNITED KINGDOM ONLY
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 lable.

change as follows:
a) Remove AC Power Cord;
b) Open cover of AC socket with flat blade screwdriver;
c) Remove selector Cam Drum and rotate to the correct voltage selection
d) Replace Cam Drum.
3) Grounding
WARNING
• To avoid electrical shock, the power cord protective grounding conductor must be connected to
earth ground.
4) Fuse Replacement
WARNING
• For continued fire protection, replace the fuse with the specified type and rating only.
• Disconnect power cord before replacing fuse.
• If the fuse is blown, there is something wrong with the instrument. Repair the cause of fault
before replacing fuse.
5) Cleaning
• Disconnect AC Power Cord from the instrument before cleaning.
• Use a soft cloth dampened in a solution of mild detergent and water. Do not spray any liquid
into the unit.
• Do not use chemicals or cleaners containing benzene, toluene, xylene, acetone or other harsh
chemicals.

4.0 First Time Use
The following text assumes that the SAFETY section of this manual has been read carefully
and understood.
Each time before the instrument is operated, make sure that it is connected to protective earth.
Before establish the connection and measurement, check if the device under test is connected
to protective earth as well.
Since the RF measurement is very sensitive, clean connectors on the front panel is very
important for the accurate measurement. Regularly cleaning up the connector is strongly
recommended.
The main power switch is located on the rear side. Switch it on to activate the Standby mode
and the power indicator on the front panel is on with red light. Push and hold the “STBY”
button for 2~3 seconds to turn on the unit. The power indicator will turn into green. Pushing
and holding the same button turns the unit to standby mode. When the unit is turned into
standby or off, the last setting is stored and recalled when it is turned on again.
4.1 Internal calibration signal
A 100MHz -30dBm calibration signal is built-in for internal calibration. Turn it on and off by
the following function keys.
Sysetm : Push System key.
F3 : Push F3 key to switch the internal calibration signal ON/OFF.
It is not a well-filtered signal. When the unit is turned on, if 100MHz and harmonics appear on
the display, check this signal is ON or OFF first.
