To have XENTISSIMO ready whenever needed, power-management is crucial at
every implementation level. Tests revealed that putting the intensity of the display
backlight at 50% for half the transaction time, offers a 20% extra operational time
as compared to having the intensity at 100% during the whole transaction.
Currently, we guarantee XENTISSIMO to work for 300 transactions a day and one
ticket printed per transaction. Over a period of 4 days, an average of 50
transactions a day is ensured. In stand-by mode (GSM/GPRS active), guaranteed
uptime is at least 7 days.
The battery can be charged either by connecting the power adapter to the
XENTISSIMO or by placing the XENTISSIMO on its cradle (for in-door or in-car
use). A separate battery charger is not available for this type of battery. As
Lithium-Ion batteries do not suffer from the “memory effect”, it is no problem to
have them charged all the time. Recharging an empty battery takes about 2,5
hours.
Tip: For the XENTISSIMO to work, the battery must be in place (even
when the terminal is connected to the power adapter).
It’s normal for a Li-Ion battery to reach the end of its life after 3 years (counting
from production on). Hence, during the XENTISSIMO lifetime, the battery needs
replacing at least once. The set-up of the logistic chain should guarantee a FIFO-
based flow of the batteries, which are supplied in the terminal box and as spare
parts.
When not yet delivered to a customer, XENTISSIMO terminals need to be held in
stock with the battery separate from the terminal, not to reduce the battery
lifetime. Li-Ion batteries do discharge inside the terminal, even when it has been
switched OFF.
