[. . . ] CAUTION Items indicated by this indication are precautions which, if ignored, may result in injury or material damage. · The term `injury' here refers to injuries such as cuts, bums or electric shock, the treatment of which will not likely require hospitalization or longterm attention. · `Material damage' refers to damage to facilities, buildings, acquired data, etc. 1. For safety in handling this laser product, operate it according to the instructions shown on the warning label, the location of which is shown in the following illustration. 2. [. . . ] Blink of 1 red lamp Replace the battery. Turning on 1 red lamp Turning on 1 green lamp NOTE: · When 4 pcs rechargeable batteries type D are used, only 2 green lamps are turned on even if they are fully charged. 18 (3) Auto/manual change key 1 Manual mode display lamp OFF LEVEL 2 MANUAL MODE BATTERY CHECK POWER ON OFF 3 Auto/manual change key 4 When the Auto/manual change key is being pressed for more than 2 seconds, the manual mode display lamp is turned on in red. The automatic self-leveling begins and the automatic self-leveling function stops after completion of automatic leveling. During the manual mode, the laser beam is emitted even if the instrument is tilted largely (out of correction area). When the Auto/manual change key is pressed again, the manual mode display lamp is turned off, the manual mode is reset and returns to normal function. NOTE: · Simple grade setting can be done by manual mode, but usually performed without stopping the automatic self-leveling function (without pressing the Auto/manual change key). During the manual mode, the horizontal accuracy of emitted laser beam is not guaranteed. · During the manual mode, the manual mode display lamp is turned on in red. 19 (4) Switching the rotation speed · Please switch the rotation speed after turning off the instrument power supply. [From 300 to 600 rpm] Manual mode display lamp Off level display lamp OFF LEVEL VEL 1 2 MANUAL MAN AL MODE BATTE Y TERY CHECK POWER WER ON OFF 3 Push the power supply key while pushing the Auto/Manual change key. Manual mode display lamp and off level display lamp blink in red a few seconds and tell that the rotation is switched to 600 rpm. The switched rotation speeds is memorized even if power supply is turned off. Auto/manual change key OFF LEVEL VEL 4 MANUAL MAN AL MODE BATTE Y TERY CHECK POWER WER Turn off the power supply and then push the power supply key while pressing the battery check key to return to 300 rpm. ON OFF Battery check Power supply key NOTE: · When the instrument is set to 600 rpm, the Manual mode display lamp and off level display lamp blink in red for a few seconds after power supply is turned on. · Rotation speed is set to 300 rpm on factory shipping. 20 2. 3 Warning display The off level lamp will turn red and the laser beam will be shut off under the following conditions. Off level display lamp OFF LEVEL MANUAL MODE BATTERY CHECK POWER ON OFF (1) When the instrument is tilted more than ± 5. 7° (± 10%) then power supply is turned on Turn off the power supply and install the instrument horizontally (within ± 5. 7°) and turn on the power supply again. Pushing the switch again turns off the illumination. NOTE: · For either the buzzer sounding or silencing to be selected, check with the mark in the liquid crystal display (see the figure on the above). · The buzzer sounding/silencing alternates each time the buzzer switch is pushed. · The buzzer sounding is initiated when the power turns on. · The illumination turns off automatically if no laser beam is received and any switch is not operated for about one minute. To illuminate the display again, push the illumination switch once more. 29 [Detecting the reference level] At the measuring point, set the position of the detector nearly to the height of the beam emitting aperture of the instrument. Position the detector where the buzzer sound (or the beam reception display appears) by directing the detecting display nearly toward the instrument and moving the detector up and down. Move the detector up and down again according to the beam reception display (or the buzzer) and obtain the reference level. Move the detector down as it is positioned high. The buzzer sound beeps at short intervals. This is the reference position. The buzzer sound beeps continuously. Move the detector up as it is positioned low. The buzzer sounds lasting beeps intermittently. NOTE: · When detecting the reference level, the detector should face the instrument in the range of about 40°, to the right and left from the front. 30 [Direct marking] After the reference level has been detected, mark a line along the detector's index, or its top or bottom end. [Plain rod marking] After the reference level has been detected, mark a line along the plain rod's top or bottom end. NOTE: · If a line was marked along the detector's top or bottom end, be sure to make measurement compensation as described on the back of the detector. · The detector should previously be positioned correctly on the plain rod according to the reference mark. [. . . ] Instrument's tilt exceeds auto leveling area. (± 5. 7°) Instrument is tilt largely by any cause. After power supply turns on, unstable state of auto self-leveling function continues approx. 3 min. NOTE* Checking point 1 2 2 Replace with fresh batteries or charge battery Check the polarity of the batteries. [. . . ]
