FAQ

A “reset” returns the controller to its delivery status. To do this, press the + (plus) and - (minus) buttons at the same time for more than 10 seconds. Following this, a display test is automatically carried out. The date and time for initial start-up can be set.

Notes:

Devices with no index label (e.g. RTR top unit with clock, item no. 0389 xx)

In the case of devices with no index label, the rate deviation factor must be noted before performing the reset. You can find this factor on the back of the top unit. Once you have programmed the time and date, set the rate deviation as follows:

• Press Set and Prog at the same time for approx. 10 seconds. “n” flashes and then the clock appears, target or actual. (Time is factory-set)
• Press the “Plus” button ten times until a flashing “U” appears.
• Press Set to select and set the desired value using the plus or minus button.

Devices with index label (e.g. RTR top unit with clock, item no. 0389 xx) index: I00)

In the case of devices with an index label, the rate deviation correction factor is permanently stored in the EEPROM.
