Charging the battery Prior to first use, the battery must be charged for 24 hours ! ® Ray-pex 5 is powered by a NiMH rechargeable battery. The battery status is shown during measurement and while recharging. If the battery is low, the last segment on the battery indicator blinks and the battery ®...
Operation Important advice To isolate the working area always place a rubber dam. Prior to measurement the access cavity must be dried with a cotton pellet in order to prevent leaking current. Select the size of the measuring file to slightly grip at the apex. Always wear gloves during the measuring procedure.
► General Information ® The device does not need to be calibrated. Ray-pex 5 works with nearly all types of metal instruments, e.g. stainless steel and NiTi files (no strongly oxide-coated NiTi files). The size of the file must correspond to the size of the canal, i.e. it must fit the apical constriction.
Fig. 7 ● Preapical and apical region On the right side of the display, the segments of the APEX ZOOM fill-up while the file advances (Fig. 8). Fig. 8 The segments show the position of the file tip: ● 4 blue segments: warning zone close to the apical region ●...
The movement of the file along the apical region is accompanied by audio signals which increase in frequency the deeper the file advances. As soon as its tip reaches the apical foramen a constant beep will sound. Note: As with all electronic length determination devices, the scale shown in the display does not represent mm or inches! Once the file tip has passed the apical foramen the warning dot will appear and short warning beeps will sound (Fig.
► Interruption of measurement During the measurement cycle the file clip may be disconnected from the file and reconnected at any time without interrupting the measurement (e.g. when the file is changed to a larger size or when a second canal should be measured). The device detects automatically that a new measurement is initiated and signals it with two short beeps.
Please first review the below checklist in order to exclude any user error or anatomic/other peculiarities before contacting your dealer. If the problem persists please contact either your local dealer or Dentsply Limited directly.
Is the lip clip connected? Check the cable and plug connections: Are the cable and plugs Are they plugged-in connected correctly? correctly? Is the measurement cable Check visible damage to damaged, e.g. torn? cable or plug? The electric circuit is not complete, i.e.
Short circuit due to excess Dry the access cavity with liquid (irrigation solution, a cotton pellet / air-blower. saliva, blood) in the pulp chamber? In case of excess blooding wait until it can be stopped. For isolation: Is there a direct contact of the - adequate preparation measuring file with the gingiva filling...
In these cases, ® it is important to use the Ray-pex 5 recording as the more accurate measurement. In the case of a lateral canal curvature the x-ray image may show a shorter working length than with Ray-pex 5. Rev. 3 01/2012...
