The system should now be tested prior to securing the covers. All testing is done by
observing the LEDs (pos 8 / Fig. 6) on the PCB electronics package. The PCB electronics
package has an infrared detector. Make sure that S10 is in charge position.

ofbeeps should end.
Faultelimination:Ifno beep,replacethe remotecontrol.
6. Makeaseriesof exposuresto be certainthe remote systemis functioning
properly.Set thekVto 90 and125(133if possible)and maximum mAs forthe
exposures.
Make certain there are no other mobile units with a
TechSwitch remote system in line-of sight. This
includes any units behind a window or lead glass. If
there are other mobiles in line-of-sight, power down
those mobiles while operating the other.
The exposure control function of this system is a
"dead-man" type switch. If the exposure command is
interrupted during an exposure, the exposure is
automatically discontinued.
All four LEDs on the TechSwitch PCB must be lit for an
exposure to occur.

Operation 4
Remote control (Option) 4
Take the remote control out of its remote holder. Step back from the X-ray unit
(up to 36+ feet / 10,9 m), and aim the remote control at the remote sensor on the front arm
of the X-ray machine.
The remote control is used in two-step. When pressing the exposure release switch once,
the preparation cycle is activated. The green "Ready" lamp goes out and does not light up
again until anode rotation has reached full speed (after approx. 2.5 s). This is indicated by
three short "beeps". The generator is now ready for exposure release.
To release the exposure, press the exposure release switch asecond time,and hold it down
until the exposure is terminated. The amber exposure indicator lights during the exposure.
The indication lasts somewhat longer than the actual exposure, in order to make the oper-
ator aware of very short exposures. A longer beep indicates the end of the exposure.
After the exposure is completed, both the X-ray unit and remote control will automatically
return to stand-by mode.
Return the remote control back to its remote holder on the X-ray unit.
Make certain there are no other mobile units with a
TechSwitch remote system in line-of sight. This
includes any units behind a window or lead glass. If
there are other mobiles in line-of-sight, power down
those mobiles while operating the other.
It is possible to wait a maximum of 15 s in the prepara-
tion position before releasing the exposure, otherwise
the preparation will automatically be switched off.
If the remote control is not returned to its holder within
three minutes after use, the Remote finder feature will
activate causing the remote control to beep. The beeps
will continue indefinitely until the remote control is
located and put back in the remote holder.
