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 read head to be cleaned regularly. This can be done
easily, using readily available cleaning cards.
BOARD REMOVAL...
The TR
-
1000 terminal contains one main circuit board
PCB221
. This can be removed as a complete assembly for repair or replacement. This
must not be done by anyone not trained to do so. If it is necessary to remove the board,
proceed as follows:
Remove power from the terminal.
Remove the rear of the case.
Unplug the reader cable from the connector/s marked
HDR4
or
HDR5
on the circuit
board.
Unplug the keypad cable from the connector marked
HDR3
on the circuit board.
Unplug or detach any other cable connections, including any external readers and
optional UPS battery if fitted.
Unscrew the LCD screws and then the pcb retaining screws from the four corners of
PCB221
.
Carefully remove the pcb from the case.
When replacing a circuit board, ensure that the replacement is the correct type and
that all links are fitted in exactly the same positions as on the original board.
BATTERY CARE...
All TR
-
1000 terminals are fitted with a non
-
rechargeable battery
on the circuit board. The battery is a 3V 200mAh button
-
cell (CR2032 or equivalent), and
is user replaceable. It has a typical hold
-
up time of >5 years and >10 year shelf
-
life. For
safety, always remove power from the TR
-
1000 before replacing the battery. Make sure
that recent data (e.g. badge clockings) has been collected by the host before removing
the battery. All batteries, especially ni
-
cads must be handled with care and disposed of
correctly.
