BATTERY CARE...
All models of the TS2020 terminal are fitted with a re
-
chargeable
battery on the
PCB234
board. This battery maintains the time, configuration and transac-
tion data. It is not serviceable and no attempt should be made to remove it. If a battery is
faulty, return the complete board, or the complete terminal, to an authorised service
centre. TS2020 terminals fitted with a UPS contain a separate high capacity battery pack
located in a slot on the inside of the front case. This battery pack can be replaced by a
trained service engineer.If it is necessary to remove the board, proceed as follows:
Remove mains power from the terminal.
Open the case and then press
SW1
push button on the UPS board
PCB239
.
Unplug the battery cable from the connector marked
PL1
on this
PCB239
board.
Unplug the power supply cable from the connector marked
PL30
on the
PCB235
board.
Remove the battery pack from its fixing.
Fit a replacement battery and connect its cable to the connector marked
PL1
on
PCB239
ensuring that the polarized plug is not reversed.
NEVER
connect the battery
to any other plug.
The battery pack is normally 'trickle' charged from the mains power supply. This can take
about 48 hours from a fully discharged state. Faster charging is permissible, at a current
of 75mA , using a charger specifically intended for NiMH cells. Full charge will be reached
in 16 hours. This process should never be attempted by anyone not qualified to do so.
All batteries, must be handled with care and disposed of correctly.
GENERAL CLEANING...
An occasional wipe with a soft cloth and a general
purpose cleaner is all that is necessary. In unusually dirty situations it may be necessary
to arrange for the terminal's slot and, if relevant, read head to be cleaned regularly. This
can be done easily, using readily available cleaning cards or lint free soft cloths.
