Remarks on Operating the ECR
The keys on the keyboard function with a light
touch. Avoid pressing the keys too hard.
Do no handle the machine with wet hands,
since this may cause electrical malfunctions
and corrosion of parts.
Do not apply thinner, benzine, or other vola­
tile materials to the cabinet or other plastic
parts. Such liquids will cause discoloration or
deterioration, if dirty, wipe off with a piece of
cloth soaked in a neutral detergent and
wrung out thoroughly.
Turn the Control Lock to OFF position when
all operations are completed after business
hours.
Never try to repair the ECR. In the event of
a problem, please call your authorized TEC
dealer, reseller or local TEC representative.
