In order for a long period of trouble-free service of the instrument, please pay
special attention to the following precautions:
1. Protect the instrument from excessive impact during transportation and
installation.
2. Be sure to verify whether the line voltage setting matches the line voltage
used.
3. Use a fuse with correct ratings only.
4. Do not apply excessive AC or DC voltage to the signal output connector
beyond the maximum voltage allowed.
5. Use the instrument within operating temperature range,
which is from 15 deg C to 35 deg C.
6. For an accurate measurement,
allow approximately 30 minutes of instrument warm-up time.
7. Avoid operating the instrument under the following conditions; direct sun light,
rapid temperature variation, high humidity, or strong magnetic field.
8. Do not alter or change the parts or their locations inside the instrument. please
contact PeakTech®company for service and calibration.

2. INSTALLATION
2.1 Power Supply
This instrument requires a power source of 100V ~ 240V AC, 50 Hz / 60Hz. AC voltage is
automatically selected to proper input range. A 3P power cord as provided with instrument grounds the
instrument chassis when connected through the compatible power receptacle.
Do not use the unit if the safety ground is broken.
Fuse is 1 A (250V) at of 100V ~ 240V “ Time delay ” type.
2.2 Incoming confidence check
Prior to packaging the instrument for shipment, extensive operational, alignment, and calibration
procedure were performed by PeakTech
®
to verify that the instrument is operating to
specifications.
To ensure the electronic integrity of the instrument on your receiving bench, you must perform the
following confidence check:
As certain that the operating voltage, then connect the AC power cord to the mains.
Turn on power.
The display will be as follows ( System Booting )
Finally the display will be as follows

Warm up 1 minutes and connect the Up-Converter (PeakTech
®
1140)
Check the DAB/DMB receiver operating
This completes the incoming confidence check.
The instrument can now be placed in.
