User manual PENTAX PLP-702

[. . . ] (Laser beam: Equivalent to class 2 Laser level) Do not try to dismantle the instrument. Dismantling it by yourself may worsen the trouble. · CAUTION · · Do not stand on the carrying case. When attaching the instrument to a tripod, make sure the instrument is securely fixed to the tripod and then securely tighten the tripod leg clamps. If not securely fastened and/or tightened, the main unit could fall off or the tripod could fall over. [. . . ] (3) If the automatic self levelling function does not stabilise the instrument for 3 minutes after the instrument is turned on. But warning is displayed farther, change the setting place of instrument or stop the construction machines which may be the cause of vibraton. NOTE: · After warning is displayed (Off level display lamp turns on in red), if no key is pressed for about 10', power supply is turned off automatically. · At above (2), warning display does not work while automatic self-leveling function stops (Off level display lamp turns on in red). 21 3. Automatic self-leveling function works and leveling begins automatically. When leveling is completed, the rotor begins to rotate and emits visible laser beam. OFF LEVEL 1 2 Manual mode display lamp Auto/Manual change key MANUAL MODE BATTERY CHECK Off level display lamp POWER ON OFF Power supply key NOTE: · Before operating the instrument, perform the `Check and adjustment of the datum point' on page 35. · Before operating the instrument, confirm that the manual mode display lamp is not turned on in red. While automatic self-leveling function, (the manual mode display lamp turns on in red) pay attention that the horizontal accuracy of emitted laser beam is not guaranteed. · When the status that the automatic self-leveling function is not stable continues for about 3', the off level display lamp turns on in red and rotation of rotor and the emission of laser beam stop. · While not in operation, be sure to turn the instrument's power switch off. WARNING · While the instrument is operating, be careful not to expose your eyes to the emitting laser beam (red light source). Exposure to a laser beam for a long time may be hazardous to your eyes. (Laser beam: Equivalent to class 2 Laser level) 26 4. 2 Operating the detector: LS7 [Power switch] Push the power switch to turn on the power to the detector. Pushing the power switch again turns off the power. 1 2 NOTE: · The liquid crystal displays all light up as shown in the above figure with the power switch pressed. · The battery's remaining capacity is always indicated with the power turned on. Check when to replace the battery, referring to the figure on the above. · The power turns off automatically if no laser beam is received and any key not operated for about ten minutes. To turn on the power again, push the power key once again. 27 [Selecting the reference level detecting accuracy] Push the detection accuracy selection switch to select the needed detection accuracy. High accuracy detection: To be selected for detecting the reference level with accuracy. Low accuracy detection: To be selected if high accuracy is not needed or when stable reference level cannot be obtained due to slight vibration at job site. High accuracy Low accuracy NOTE: · For the detection accuracy to be selected, check with the mark in the liquid crystal display (see the figure on the above). · The detection accuracy alternates each time the detection accuracy selection switch is pressed. · High detection accuracy is initiated when the power turns on. · If the point to be measured is distant, the reference level may not be displayed stably by the influence of heat waves shimming or the instrument slightly vibrating. [. . . ] · For a period of less than 10 seconds during the operation the user may be subjected to this radiation. 2) The following labels are affixed to and must remain attached to this laser product.
