1 Introduction

1-1 Introduction
Thank you for purchasing the SR2000A Frequency Monitor. The SR2000A is a worthy successor
to the SR2000 and is the "next generation" in frequency monitor. Using a five-inch TFT color
display, DSP (Digital Signal Processing) and FFT (Fast Fourier Transform), faster sampling rates
and color imaging, video display function, optional APCO25 (P25) decoder, the SR2000A opens
the door to new possibilities and applications. We put the power of FFT algorithms to work in
tandem with a powerful receiver covering 25 MHz ~ 3 GHz continuous (Cellular blocked for US
consumer version). The result is a compact color spectrum display monitor that's ultra-sensitive,
incredibly fast, yet easy to use.
The SR2000A is perfect for base, mobile or field use and can also be used in combination with a
personal computer.
Every effort has been made to make this manual correct and up to date. Due to continuous
development of the product and by error or omission, anomalies may be found and this is

1-2 Maintaining the unit

There are no internal operator adjustments. In the unlikely event of service being required,
please contact your dealer for technical assistance.
Level of risk
As the SR2000A is powered from 12V DC, there is little chance of serious injury as long as
common sense is applied.
Observe the polarity of connections if supplied AC power units is not being used. DC input is a
nominal 12V DC, with the connector wired center conductor positive. Reverse polarity connection
will damage the SR2000A and could lead to the risk of fire or explosion under severe
circumstances.
Carefully handle the AC plug of the supplied AC power unit to prevent touching the terminals
when inserting or removing from the AC plug. NEVER connect the SR2000A directly to the AC
outlet.
Handling the SR2000A
Use a soft, dry cloth to gently wipe the SR2000A clean. Never use abrasive cleaners or organic
solvents which may damage certain parts. Treat the unit with care, avoid spillage or leakage of
liquids into the cabinet and power supply. Special care should be taken to avoid liquid entering
around the keys, main dial or via the connectors.
[Note: Never push or knock the LCD screen – it is very fragile and sensitive to shock.]
Special remarks
Do not use or leave the SR2000A in direct sunlight (especially the TFT display). It is best to avoid
locations where excessive heat, humidity, dust and vibration are expected. Always keep the
SR2000A free from dust and moisture.
