GENERAL SAFETY SUMMARY

Review the following safety precautions to avoid operator's injury and loss of life and prevent damage and deterioration to this instrument. To avoid potential hazards, use this product as specified.

WARNING

■ Warnings on the Cases and Panels of the Instrument

Operator should not remove any cases or panel for any reasons. If you touch inside the instrument it could result personal shock or fire hazard. Refrain from spilling any liquid on or inserting anything flammables or piece of metal into the ventilation of the instrument. Such actions could cause fire, shock, malfunction and be an accident hazard while the power is on.

■ Warnings on Power Line

●

Make sure to connect only to the rated power line voltage. Excess voltage may cause fire.

Confirm the voltage of the commercial power line before connecting the AC power cord. The power frequency of the power line should be 50/60 Hz.

●

Warning on the Power Cord

Use only the optional power cord that is attached to this instrument. The use of the power cord other than that attached could cause fire hazard. If the attached cord is damaged stop using it and contact your local LEADER agent. Should you use a damaged cord, it could cause a shock or create a fire hazard. When you pull out the cord be sure to hold it by plug and pull from the socket not by holding the cord wire.

■ Warning on Fuse

When the fuse is melted the instrument stops operation. If the fuse melted, turn off the power switch and disconnect the power plug from the socket. If you change the fuse while the cord is connected to the socket, it could cause a shock hazard. Only use the specified type and rated current and voltage fuses. If the cause for melting fuse is unclear or if you suspect there is damage to the instrument or if you have no proper fuse at hand please contact your local LEADER agent.

GENERAL SAFETY SUMMARY

WARNING

■ Warning on Installation Environments

●

About the Operating Temperature Range

Operate the instrument between the temperature range of 0 to 40 °C. Operating the instrument at higher temperatures could cause a fire hazard. Rapid changes of temperatures from cold to warm can create internal moisture or condensation and could damage the instrument. If there is a possibility of moisture condensation allow the instrument to sit for 30 minutes without the power on.

●

About the Operating Humidity Range

Operating humidity range is

≤ 90 % RH.

Do not operate the instrument with wet hands. This could cause a shock and fire hazard.

About the Operation in the Presence of Gasses

Operating the instrument in and near the presence or storage locations of flammable, explosive gasses or fumes could create an explosion and fire hazard. Do not operate the instrument anywhere near such environments.

●

Avoid Insertions

Do not insert metals or flammable objects or drop liquid on or into the instrument. To do so could cause fire, shock, malfunction and create a dangerous accident hazard.

■ Warning while Operating

While operating the instrument if smoke, fire, or a bad smell occurs, turn off the instrument at once for it could cause a fire hazard. When such a case occurs, turn off the power switch and pull the plug of the cord from the plug socket. Contact your local LEADER agent after confirming there is no fire.

■ Warning about Ground

The instrument has a ground terminal to avoid electric shock hazard and to protect the instrument from damage. Ensure that the product is properly grounded for safe operation.

2.1 GENERAL

Model LT 416 is a precision test-signal source which provides four color systems of

NTSC, PAL, SECAM, and NTSC-4.43 for testing and adjusting all kind of video

products such as TV, VTR etc.

In addition of a composite signal output, the generator provides a Y/C output and a

component signal outputs (except SECAM) of Y/B-Y/R-Y and GBR so that it is

suitable to a production line for video products of component system.

RF output is easily selected by setting channel number while the channels are pre-

programmed by each countries.

15 test patterns including color bars, raster, convergence and circle satisfy the most

desired applications.

4.11 Battery Backup

4.11.1 Backup Capability

This generator retains the setting conditions (e. g., system, pattern settings,country

number,TV channel number) even when the power is turned off.

Data is retained about 14 days with a fully charged backup battery (ambient

temperature: ≤ 40 °C ,relative humidity: ≤ 80 % ) ,

4.11.2 Battery

Rechargeable battery is used.

4.11.3 Battery Life

When backup period becomes short, the battery should be replaced. When replacing

the battery, contact your local LEADER agent.

WARNING

4.12 Fuse Replacement

When the fuse burns out, replace it according to the procedure below.

(1) Remove the power cord from the mains to prevent accident.

(2) Rotate the fuse holder cap counterclockwise using a Phillips screwdriver to
