Life of the Parts

Fuse replacement
The TZT has a fuse that protects the TZT from high electric current and equipment
fault. If you cannot turn on the power, check the fuse to see if it has blown. Find the
reason for the blown fuse before you replace the fuse. If the fuse blows again after the
replacement, contact your dealer for information. A wrong fuse can damage the equip-
ment.

Lithium battery replacement
The lithium battery on the Main board in this equipment keeps the time data of the in-
ternal clock alive when the power is turned off. The life of the battery is approximately
three years (in power-off). When the voltage of the battery is low, the message re-
questing replacement appears at the top of the screen. When this occurs, contact your
dealer about replacement of the battery.
Note: Dispose of the battery in accordance with local regulations.
