Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de Classe B prescrites dans le règlement sur le brouillage radioélectrique édicté par le Ministère des Communications du Canada. Europe This product has been tested and found to comply with the requirements for a Class B device pursuant to European Council Directive 1999/5/EC on R&TTE, thereby satisfying the requirements for CE Marking and sale within the European Economic Area (EEA). These requirements are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential or commercial environment, and to ensure that the equipment is safe Australia and New Zealand This product conforms with the regulatory requirements of the Australian Communications and Media Authority (ACMA) EMC framework, thus satisfying the requirements for C-Tick Marking and sale within Australia and New Zealand. [. . . ] Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: ­ Do not charge or use the battery if it appears to be damaged or leaking. ­ Charge the Lithium-ion battery only in a Trimble product that is specified to charge it. Be sure to follow all instructions that are provided with the battery charger. ­ Discontinue charging a battery that gives off extreme heat or a burning odor. ­ Use the battery only in Trimble equipment that is specified to use it. ­ Use the battery only for its intended use and according to the instructions in the product documentation. Charging the Lithium-ion battery The rechargeable Lithium-ion battery is supplied partially charged. If the battery has been stored for longer than six months, charge it before use. To protect the battery from deep discharge (5 V or less), the receiver is designed to switch batteries or cease drawing power when the battery pack discharges to 5. 9 V. A battery that has reached the deep discharge level cannot be recharged and must be replaced. The following recommendations provide optimal performance and extend the life of your batteries: · · Fully charge all new batteries before use. Do not allow the batteries to discharge below 5 volts. 42 Trimble R7 GNSS and 5700 GPS Receivers User Guide General Operation 4 · · · Do not store batteries in the receiver or external charger unless power is applied. If you must store the batteries, fully charge them before storing and then recharge them at least every three months. Disposing of the rechargeable Lithium-ion battery Discharge the Lithium-ion battery before disposing of it. When disposing of the battery, be sure to do so in an environmentally sensitive manner. Adhere to any local and national regulations concerning battery disposal or recycling. 48. 2 Operating with the controller If the receiver is being powered by its internal batteries, it does not supply power to the controller when they are connected. The receiver and the Trimble controller must be charged using their own power supplies with connections to the AC power supply from the wall. 48. 3 Power output If the receiver is being supplied with power from an external source, power is automatically output on Port 1. Port 1 outputs a maximum voltage of 20 V, even if the input voltage is higher. You can use GPS Configurator or Trimble Survey Controller software to enable power output on Port 3. Port 3 can be enabled for power output regardless of whether power is supplied internally or externally. On Port 3, the output voltage is approximately 0. 5 V less than the input voltage. For example, if power is being supplied from the internal Lithium-ion batteries, the maximum battery voltage is 8. 4 V, so the maximum output voltage is 7. 9 V. Note ­ When you start a survey using the Trimble Survey Controller software, and you are using an external radio, the software automatically enables power output on Port 3. 48. 4 Firmware A receiver's firmware is the program inside the receiver that makes the receiver run and controls the hardware.
