Objects in the path of radio signals degrade the quality of the signals. Keeping an unobstructed line of sight between you and your dog’s DC 40 produces the best communication signal. Obstructed radio waves result in a poor signal. To achieve the best line-of-sight conditions, move to the highest elevation point in your area (for example, on the top of a hill).Not sure where this should go.Starting a new hunt?Start New Hunt–resets dog statistics ••and track logs, and marks your starting location.

74 Astro and DC 40 Owner’s ManualAppendixmammals. Alaska law prohibits guides from using GPS devices to assist in the taking of big game animals. This is not intended to be an exhaustive list of applicable laws and ordinances, and Garmin makes no such guarantees or warranties that this list is complete. Check your state and local laws and ordinances to ensure you fully understand any restrictions applicable to this product in your jurisdiction prior to purchase and/or use. Garmin does not assume any responsibility for any nes,penalties,ordamagesthatmaybe incurred as a result of any state or local law or ordinance relating to use of the product.DC 40 Battery WarningsIf these guidelines are not followed, the internal lithium-ion battery may experience a shortened life span or may present a risk of damage to the DC 40, re,chemicalburn,electrolyteleak,orinjury.Contact your local waste department to properly dispose of the unit/battery.Do not leave the unit exposed to a heat source or in a high-temperature location, such as in the sun in an unattended vehicle on a hot day. To prevent damage, remove the unit from the vehicle or store it out of direct sunlight, such as in the glove box.Do not incinerate the DC 40 or the battery.When storing the unit for a limited length of time, store within the following temperature range: from-4˚Fto104˚F(from-20˚to40˚C).Whenstoringtheunitforan extended time, store within the following temperature range: from 32˚Fto77˚F(from0˚to25˚C).Do not operate the unit outside of the following temperature range: •••••

Do not disassemble, puncture, or damage the battery.Replace the battery with a Garmin lithium-ion battery pack. Using another battery presents a risk ofreorexplosion.Topurchasea replacement battery, see your Garmin dealer or the Garmin Web site (www.garmin.com). Do not leave the DC 30 where a dog may ••••attempt to chew on it. If the battery cell is punctured, electrolyte can be released that can be harmful to the dog. Long-Term DC 40 Battery Storage The normal long-term decrease in the charging capacity of lithium-ion batteries can be accelerated by exposure to elevated temperatures. Storing a fully charged battery for more than three months in a location that exposes it to high temperatures (above 70°For21°C)cansignicantlyreduceits recharging capacity. Before storage, charge the battery to approximately 50% of capacity and store it in a cool, dry location where temperatures are not expected to exceed typical household levels. Do not store a fully depleted battery because it may not recharge after an extended period of storage. After storage, fully charge the battery again before using the DC 40.

78 Astro and DC 40 Owner’s ManualAppendix310.IMPORTANT WARNINGS: READ THIS INFORMATION BEFORE USING YOUR ASTRO DOG TRACKING SYSTEM:Exposure to Radio Frequency Signals–Your product is a low power radio transmitter and receiver. When it is on, it receives and also sends out radio frequency (RF) signals. In August 1996, The Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for handheld wireless radios. Those guidelines are consistent with safety standards previously set by both U.S. and international standards bodies: American National Standards Institute (ANSI) IEEE. C95.1-1992; National Council on Radiation Protection and Measurements (NCRP) Report 86; International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996. Those standards were based on comprehensive and periodic evaluationsoftherelevantscienticliterature. For example, over 130 scientists, engineers, and physicians from universities, government health agencies, and industry reviewed the available body of research to develop the ANSI Standard (C95.1). The design of your radio complies with the FCC guidelines (and those standards).For body-worn and face-held operation, this radio demonstrates compliance and meets the FCC RF exposure guidelines for uncontrolled exposure (general population) when used with approved accessories supplied with or designed for this product. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. Antenna Care–Use only the supplied antenna. Unauthorized antennas,
Astro and DC 40 Owner’s Manual 79Appendixmodications,orattachmentscoulddamage the radio and may violate FCC regulations. Warning: Do not use any radio that has a damaged antenna, because if it comes into contact with your skin, a minor burn can result.Electronic Devices–Most modern electronic equipment is shielded from RF signals. However, certain equipment may not be shielded against the RF signals from your wireless radio.Pacemakers–The Health Industry Manufacturers Association (HIMA) recommends that a minimum separation of six inches (6”) be maintained between a handheld wireless radio and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with the independent research by and recommendations of Wireless Technology Research. Persons with pacemakers should ALWAYS keep the radio more than six inches from their pacemaker when the radio is turned on, should not carry the radio in a breast pocket, should use the ear opposite the pacemaker to minimize the potential for interference, and should turn the radio off immediately if you have any reason to suspect that interference is taking place.Hearing Aids–Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives.Other Medical Devices–If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from external RF energy.
80 Astro and DC 40 Owner’s ManualAppendixYour physician may be able to assist you in obtaining this information.Turn your radio OFF in health care facilities when any regulations posted in these areas instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.Vehicles–RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also consult the manufacturer of any equipment that has been added to your vehicle.Posted Facilities–Turn your radio OFF in any facility where posted notices so require.Commercial Aircraft–Many commercial airlines prohibit the use of FRS/GMRS radios on board. Switch OFF your radio before boarding an aircraft or check the airline rules.Blasting Areas–To avoid interfering with blasting operations, turn your radio OFF when in a “blasting area” or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.Potentially Explosive Atmospheres–Turn your radio OFF and do not remove your battery when you are in any area with a potentially explosive atmosphere. Obey all signs and instructions. Sparks from your battery in such areas could cause an explosion orreresultinginbodilyinjuryorevendeath.Areas with a potentially explosive atmosphere are often, but not always clearly marked. They include fueling areas such as gasoline stations, below deck on boats, fuel or chemical transfer or storage facilities; vehicles using
Astro and DC 40 Owner’s Manual 81Appendixliqueedpetroleumgas(suchaspropane or butane); areas where the air contains chemicals or particles, such as grain, dust, or metal powders; and any other area where you would normally be advised to turn off your vehicle engine.
