The intensity of the fluorescent tube used for backlight illumination of the Flat Panel Display
will gradually decrease over time. As a result, periodic replacement may be necessary.
Agilent recommends replacement of the Backlight Tube Assembly (latest flat panel display)
after 25000 hours (2.85 years) of continuous use or if there is noticeable decrease in the
display illumination. The procedure for replacing the Backlight Tube Assembly depends on
the model and can be found in the appropriate chapter on “Repairing”.

THE AGILENT MODEL V24CT/V26CT COMES WITH TWO SEALED LEAD-ACID
BATTERIES. TO PREVENT DAMAGE TO THE BATTERIES, THE BATTERIES
SHOULD BE CHARGED FULLY PRIOR TO USE.
Only batteries obtained from Agilent Technologies specifically for use with the Model
V24CT/V26CT should be used. Use of other batteries could damage the Model V24CT/
V26CT.
Upon receiving the Model V24CT/V26CT, fully charge the batteries before using the unit by
inserting the batteries, leaving the unit off, and plugging the AC power cord into an AC
source.
A battery's cycle life is the depth of discharge for each cycle. One cycle is equivalent to one
discharge and then full recharge of the battery. A battery that has been subjected to a lower
depth of discharge per cycle will have a longer cycle life than one with greater depths of
discharge. An average battery will have a cycle life of 250 cycles depending upon the number
and type of modules used and the depth of discharge.
Recharge the batteries to their full state after each use.
A battery will retain more of its residual capacity for a longer period of time if kept as cool as
possible. Residual capacity drops from 100% charge to 50% charge over an 18 month period
if the battery is kept at 20°C.
Store the batteries in a dry, cool place. A refrigerator is an excellent place to store batteries.
Never disassemble the batteries, or attempt to use broken or leaking batteries. The batteries
use sulfuric acid as an electrolyte, and sulfuric acid can burn skin and clothes. If sulfuric acid
does leak out of the batteries, wipe it up with a cloth and neutralize the acid with some
available alkaline substance such as ammonium solution or sodium bicarbonate (baking
soda). If the electrolyte should come in contact with skin or eyes, immediately flush the area
with water and consult a physician.
