[. . . ] When carrying the tripod, be careful so that the tripod shoes do not strike anyone. When setting the tripod, make sure not to stab someone's hand or foot with the tripod shoes. Operate this laser product with the height of laser avoiding that of eyes of car drivers and pedestrians. Avoid putting the laser on a highly reflective material such as mirror. [. . . ] The remaining battery display lamp is turned off about 15 seconds later after the battery check key is pressed. Remaining battery display lamp Turning on 3 green lamps Workable enough. 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. · The buzzer sounding/silencing alternates each time the buzzer switch is pushed. · 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. [Plain rod marking] After the reference level has been detected, mark a line along the plain rod's top or bottom end. 31 [Reading the staff] After the reference level has been detected, read the staff, using the index on the rod adapter. Staff Index Rod Adapter NOTE: · When detecting the reference level, slightly loosen the fixing screw for the rod adapter and move the detector up and down along the staff. 32 5. Maintenance 5. 1 Maintenance after use [Stains on the main body] Brush dust off and wipe off moisture with tissue paper. [. . . ] bureau of Radiological Health requires the following information to be provided to the user: 1) Specifications of Laser Radiation. This laser system is designed and built to have a GaAIAs laser diode radiating at 635nm ± 15 nm. Radiant power This laser product is designed and built to radiate a maximum average radiant power of 920µ W as scanning beam during functional operation. The user may be subject to this radiation as a scanned beam while the rotor is rotating until such time that the instrument is turned off. [. . . ]
