any operation to ensure your safety and to keep

the instrument in the best possible condition.

Safety Symbols

These safety symbols may appear in this manual or on the

instrument.

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 the instrument or to

other properties.

DANGER High Voltage

Attention Refer to the Manual

Earth (ground) Terminal

Frame or Chassis Terminal

Do not dispose electronic equipment as unsorted

municipal waste. Please use a separate collection

facility or contact the supplier from which this

instrument was purchased.

Safety Guidelines

General

Guideline

CAUTION

 Do not place any heavy object on the instrument.

 Avoid severe impact or rough handling that leads

to damaging the instrument.

 Do not discharge static electricity to the instrument.

 Use only mating connectors, not bare wires, for the

terminals.

 Ensure signals to the RF input do not exceed

+30dBm.

 Do not block the cooling fan opening.

 Do not disassemble the instrument unless you are

qualified.

(Measurement categories) EN 61010-1:2010 specifies the

measurement categories and their requirements as follows. The

instrument falls under overvoltage category II.

 Overvoltage category IV is for equipment installed at or near

the origin of supply to a building, between the building

entrance and the main distribution board.

 Overvoltage category III is for equipment intended to form

part of a building wiring installation.

 Overvoltage category II is for equipment intended to be

supplied from the building wiring.

 Overvoltage category I is not relevant to this standard.

Power Supply

WARNING

 AC Input voltage range: 100V~240V (Max. 82W)

 Frequency: 50 - 60Hz

 To avoid electrical shock connect the protective

grounding conductor of the AC power cord to an

earth ground.

SAFETY INSTRUCTIONS

7

Power Cord

Requirements

The connector that plugs into the socket outlet must

be a grounding-type male plug designed for use in

your region. It must have certification marks showing

certification by an agency in your region. The

connectors that plug into the Appliance Inlets (AC

receptacle) must be an IEC 60320, sheet C13, female

connector. If the power cord supplied with the system

does not meet requirements for use in your region

discard the cord, do not use with adapters.

Cleaning

 Disconnect the power cord before cleaning.

 Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

 Do not use chemicals containing harsh material

such as benzene, toluene, xylene, and acetone.

Operation

Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Temperature: 5°C to 45°C

 Humidity: <90% (non condensing)

(Pollution Degree) EN 61010-1:2010 specifies the pollution

degrees and their requirements as follows. The instrument 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.

 Altitude:< 2,000 meters

Disposal

Do not dispose this instrument as unsorted municipal

waste. Please use a separate collection facility or

contact the supplier from which this instrument was

purchased. Please make sure discarded electrical

waste is properly recycled to reduce environmental

impact.

First Use Instructions

Use the procedures below when first using the C-1200 to tilt the

stand, power up the instrument, update the firmware and to

restore the default settings. Lastly, the Conventions sections will

introduce you to the basic operating conventions used throughout

the user manual.

Power Up

Steps

1. Insert the AC power cord into the power socket.

The PWR LED indicator lights in orange which

mean that the C-1200 is in standby mode.

PWR SYS

2. Press the power button for a few seconds to

turn the C-1200 on.

3. The PWR LED indicator turns from orange to

green, The C-1200 will start to boot up.

Power Down

Description

The C-1200 has two methods to power down:

Normal and Forced Power Down.

The normal power down method will save the

system state and end any running processes. The

state is saved for the next time the instrument is

turned back on.

The forced power down method only does a

minimum state save.

Normal Power

Down

Press the power button. The system will

automatically handle the power down procedure

in the following order:

 The system state is saved.

 Outstanding processes are closed in sequence.

 The system enters standby mode (the power

key changes from orange to blue).

Note

The process takes about 10 seconds.

Forced Power

Down

Press and hold the power button for 4 seconds

until the system turns off and the power button

turns blue.

Note

The forced power down mode might cause the C-

1200 to perform a longer system check the next

time it is powered up.
