Charging the Smart
Battery (VX 520
GPRS Only)
After unpacking your VX 520 GPRS terminal, install the battery and connect the
power pack to the unit for 6 hours or until fully charged.
The smart battery has a safety circuit to protect the Li-ion cells from overcharging
and over-discharging. If the battery is over-discharged, the safety circuit shuts
down the battery. The battery must then be recharged to restore operation.
Battery Life
The VX 520 GPRS smart battery can be charged and discharged hundreds of
times, but will eventually wear out. When operating times are noticeably shorter
than usual, it is time to buy a new battery (see Accessories and Documentation for
ordering information).
Privacy Shield
(Optional)
The privacy shield protects the customers’ PIN entry from being seen by the
cashier or other customers. The illustration shows an example of a VX 520
with
the optional privacy shield.
Figure 31 Optional Privacy Shield
NOTE
The VX 520 GPRS terminal automatically shuts off when the smart battery
reaches the critically low charge state. If this occurs, the smart battery must be
recharged for a minimum of 1/2 hour before it can power the terminal. It may take
several recharge attempts to reset the safety circuit when charging a smart
battery that has been discharged below this critical state.
WARNING
Do not dispose of batteries in a fire. Li-ion batteries must be recycled or disposed
of properly. Do not dispose of Li-ion batteries in municipal waste sites.
NOTE
Merchants who install the terminal without the privacy shield must ensure the
cardholder’s privacy when entering his PIN by positioning the terminal away from
open view.
