Replacing Battery Press the battery lock on both sides, remove the battery. When the remaining voltage is less than one grid, please stop your operation and charge it as soon as possible. Note: Before remove the battery from the instrument, make sure that the power is turned off. Otherwise, the instrument may be damaged. 4 Note:

a) The operating time depends on the outside conditions, such as ambient temperature, charging time, the cycles of charging, etc. It is recommended for safety to charge the battery beforehand or to prepare spare full-charged batteries. b) The remaining voltage of battery shows the power level, regarding to the current measure mode. In normal, the consumption of distance measurement mode is higher than angle measurement mode. When switching the measurement mode from angle to distance in a low battery voltage, it might interrupted the operation. Charging The battery must be charged prior to using before the first time operation. The battery SB-35a should be charged only by the official charger NC-10, which packed together with the instrument. Please connect the power supply in 220V, under 0~45C. When the indicator on the charger is red, the charging process has begun. When indicator turns green, the charging has finished. For safety, please pull out the battery and charger in time. Note: In order to get the maximum service life, please charge the battery at least once a month. 5 1.5 DISMOUNTING/MOUNTING THE TRIBRACH Dismounting If necessary, the instrument can be dismounted from tribrach. Turn the locking knob about 180 counter-clockwise to disengage anchor jaws, and take off the instrument from tribrach. Mounting Insert three anchor jaws into holes of tribrach and line up the directing stub with the directing slot. Turn the locking knob about 180 clockwise to mounting the instrument. 1.6 EYEPIECE FOCUSING Sight the Telescope to bright place and rotate triangle mark on EDM cover. the eyepiece tube to make the reticle clear.

INSPECTION & ADJUSTMENT The instrument has passed the procedure of inspection and adjustment before releasing to the market, which ensures that it meets quality requirement. However, after long periods of transportation or the changeable environment, some influences may occur to the internal structure. Therefore, before the instrument is used for the first time, user should check and adjust the functions we introduced in this session to ensure the precision of the job. 12.1 PLATE VIAL Inspection Adjustment Loosen the horizontal tangent screw, rotate the 1. If the bubble of the plate vial moves away equipment to ensure that the plate vial is parallel from the center, bring it half way back to the to the direction of foot screw AB. Adjust the center by adjusting the screws, which is parallel screw A/B in opposite direction to move the to the plate vial. Correct the remaining half by bubble in the center.

Product hardware has the capability to operate on Channel 12 and 13. However, these two channels will be disabled via software and will not be accessible to user. Product hardware has the capability to operate on Channel 12 and 13. However, all the operated channels cant be changed in the RF parameter via software. All channels have complied with all of the requirements sets out in FCC Part 15.247. Product hardware has the capability to operate on WiFi Channel 12 and 13, and meets the requirements of KDB 594280 D01 v02r01. Please note:

1.) By default, this device operates in a mode that is compliant with the U.S. requirements. 2.) This device will also use supplemental information such as geo-

location data to determine that it is operating outside the U.S., if necessary, to change its power. Such supplemental data will be derived from the following:

Global Navigation Satellite System (GNSS)7 sensors in the device Mobile Country Code (MCC),8 or MCC with a Mobile Network code

(MNC), received from a CMRS9 carrier and received directly by a receiver on the device Country information derived from multiple adjacent access points (for example using IEEE Std 802.11d provisions) may be permitted on case-by-

case basis Other suitable geo-location data based on IP addresses or other reliable source. Signature:
