Copyright Notice This is the V1.0 (January, 2026) revision of the Mercury User Guide. It cannot be copied or translated into any language without the written permission of ComNav Technology Ltd. Technical Assistance If you have any question and can't find the answer in this manual, please contact your local dealer from which you purchased the Mercury. Alternatively, request technical support from ComNav Technology Website:www.comnavtech.comor technical support email: [email protected] feedback about this Guide will help us to improve it with future revisions. Safety Information Before using the receiver, please make sure that you have read and understood this User Guide, as well as the safety requirements. ⚫ Connect your devices strictly based on this User Guide ⚫Install the GNSS receiver in a location that minimizes vibration and moisture ⚫Avoid falling to ground, or colliding with other items MercuryLaserUser Guide 3 ⚫ Keep a sound ventilation environment ⚫ Change the cable if damaged Related Regulations The receiver contains integral Bluetooth® wireless technology. Regulations regarding the use of the datalink vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. But in some countries the administrative permissions are required. For license information, please consult your local dealer. Use and Care The receiver can withstand the rough treatment that typically occurs in the field. However, the receiver is high-precision electronic equipment and should be treated with reasonable care. Warning and Caution An absence of specific alerts does not mean that there are no safety risks involved. A Warning or Caution information is intended to minimize the risk of personal injury and/or damage to the equipment. WARNING-A Warning alerts you to a potential risk of serious injury to your person and/or damage to the equipment, because of improper operations or wrong settings of the equipment. CAUTION- A Caution alerts you to a possible risk of damage to the equipment and/or data loss. Warranty Notice ComNav Technology does not warranty devices damage because of force majeure (lighting, high voltage or collision). ComNav Technology does not warranty the disassembled devices. MercuryLaserUser Guide 4 FCC Warning This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help RF Exposure Information (SAR) : This device meets the government's requirements for exposure to radio waves. This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government. The exposure standard for wireless devices employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg for body and 4.0W/kg for Limbs. *Tests for SAR are conducted using standard operating positions accepted by the FCC with the device transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the poser required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. The FCC has granted an Equipment Authorization for this device with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this device is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/ oet/fccid after searching on FCC ID: 2ACHBMERCURY For body worn operation, this device has been tested and meets the FCC RF exposure guidelines for use with an accessory that contains no metal and the positions the device minimum of 5mm from the body .
