We offer carrying out basic operations (button function check, check of display illumination, etc.) which do not require any technical equipment. Furthermore, in close cooperation with the customer, we are able to provide a highly-qualified check by using various measuring devices. This type of check often requires a special measuring device available only at costumer premises. Our employees are able to become familiarized with use of such devices fast and competently. In case a check requires a device which is not available, we are able to devise an alternative solution by using our own or leased devices.
