4 SERVICE MODE
Technical manual Planmeca ProX 21
4.5 Operation of pre-programmed settings keys (kV hold)
Enter the service mode according to the instruction given in section 4.2 “How to enter/exit
service mode” on page 19.
Press the parameter adjustment up key until the parameter number 15 appears on the kV
display.
The number indicating the operation of preprogrammed settings keys (0 or 1) is shown on
the time display.
0: Normal operation (factory setting). The preprogrammed settings keys operate as
described in the Planmeca ProX user’s manual.
1: kV hold. The selection of a preprogrammed setting does not affect the prior manually
inserted kV value, but the exposure time is recalculated to achieve constant optical density
on the film. In the case the kV value is now manually altered, the exposure time will also
be changed automatically. If the exposure time is manually altered, the unit will return into
manual mode. At any time, the preprogrammed setting for the kV value, mA value and
exposure time for any tooth position is called by selecting the preprogrammed setting and
pressing the child mode selection key twice.
Press and hold down the Select key until the number starts to blink, and the number can
now be changed with the parameter adjustment keys.
Accept the new setting by pressing the Select key.
To exit the service mode press the Mode key for 2 seconds.
