Page 3: Safety Instructions
• The laser plane should be set up above eye level. • Use instrument for its intended tasks only. • Do not attempt to dismantle intrument. • Repairs should only be carried out by geo-FENNEL authorized workshops. Please contact your local dealer. • Do not remove warning labels or safety instructions. -
Page 4: Specific Reasons For Erroneous Measuring Results
SPECIFIC REASONS FOR ERRONEOUS MEASURING RESULTS • Measurements through glass or plastic windows; • dirty laser emitting windows. • After instrument has been dropped or hit. Please check accuracy. • Large fluctuation of temperature: If instrument will be used in cold areas after it has been stored in warm areas (or the other way round) please wait some minutes before carrying out measurements. -
Page 5: Important
IMPORTANT! READ BELOW INSTRUCTIONS BEFORE USING YOUR INSTRUMENT • Make a full check of the instrument before using it. Make sure that the instrument’s functions, power, original settings and revised parameters meet your requirements before you operate it. • To avoid direct sunlight to the instrument’s lens, never leave the instrument exposed to extreme heat longer than necessary, or it could affect the instrument’s accuracy. -

Page 9: Preparation For Measurement
PREPARATION FOR MEASUREMENT • Tripod Place the tripod legs to a suitable length and tighten the locking clamps. Make sure that the tripod is set up safely. • Mount the instrument Mont the instrument onto the tripod carefully, and fix it with the 5/(„ retaing bolt of the tripod. • Adjust the vials First adjust ciruclar vial, then adjust plate vial. -
Page 10: Battery Status Indication
BATTERY STATUS INDICATION The battery symbol on the display shows the current battery status. Full power Effective Still effective Low power but effective, replace the alkaline battery / recharge NiMH battery pack. Instrument will shut off automatically shortly. Replace alkaline battery / recharge NiMH battery pack immediately. -
Page 11: Horizontal Angle 0-Set
HORIZONTAL ANGLE OSET (OSET) Aim at target A using crosshair of the telescope. Press 0SET key once to set reading of horizontal angle 0°00’ 00”: 0SET key is only effective for the horizontal angle. Horizontal angle can be set 0 at any time except in holding status (HOLD key). -
Page 12: Horizontal Angle Locked - Unlocked
HORIZONTAL ANGLE LOCKED - UNLOCKED Turn the tangent knob and place the required horizontal angle. Press HOLD button to hold the current value of horizontal angle.Value will flash while this function is active. Press HOLD button again to release the value. SLOPE PERCENT MODE Measuring in angle mode, the vertical angle could be transformed into percent of grade. -
Page 13: Distance Measurement Using Stadio Method
DISTANCE MEASUREMENT USING STADIA METHOD Distance measurement can be carried out by using the crosshair. • Read the levelling rod • Aim at the levelling rod with the telescope of the in- strument. • Mulitply the value of the distance „d“ between the two stadia hairs with 100. -
Page 14: Use Of The Laser
The laser beam is pulsed and can therefore be used together with any geo-FENNEL receiver for rota- ting lasers. Thus, FET 402K-L can be applied for any task that would require use of a rotating laser. Switch laser beam on with laser key.Turn the laser key to adjust brightness of the laser beam. -
