Description 2 Receivers To Suit Your Needs The F600 includes 2 types of receivers. The large receiver located on the comfort collar emits first a sound (beep) when the correction zone is crossed, then a sound together with a vibration (1 – 5 levels of automatic gradual escalation of the alert) or a sound with a static pulse (1 – 5 levels of automatic gradual escalation of the alert). A switch on the side of the receiver can be used to select between two types of correction (vibration or static). This receiver is suitable for small, medium, large dogs and untrained dogs. The small receiver in the form of a pendant on a ring only gives an audible warning. Suitable for small dogs and well-trained dogs. The sound correction is automatically increased gradually – the beeping speed increases from level 1 to 3. The F600 operates with low power consumption and prevents overheating. The disconnection indicator alerts you to any problems. Intelligent power adjustment with low power consumption and minimal heat generation ensures a stable signal without overheating. Built-in lightning protection protects the base from electrical surges caused by lightning strikes. Zone settings The F600 has sound, vibration, and pulse functions – depending on the receiver you choose. The sound escalates in 3 levels, and the vibration and static pulse are in 5 successive levels. The interactive knob on the base allows you to adjust the width of the boundary for your dog’s movement to 10 degrees. Correction type The F600 has 5 levels of electrostatic correction that automatically increases over time. It also has 5 levels of automatic vibration and 3 levels of sound. Wire in the package The F600 contains 150 meters of heavy duty insulated wire. If the wire in the package is not enough, then extra can be purchased from us. The circuit can be extended with additional wire to cover up to 40 acres. Click Here For Extra Wire Charging The F600 has universal Type C charging – base and receiver. Both the base and receiver support a 5V 2A input, so they are compatible with most adapters. The small receiver can last up to 3 days on a single charge, the large receiver up to 7 days. Charging time for both receivers is about 1.5 hours. Waterproofing Both the large and small receivers are waterproof and IPX7-rated. The base is not waterproof, we recommend placing it in a dry environment preferably indoors. Number of dogs The F600 can be used for an unlimited number of dogs. You can easily expand it by adding additional receivers. Collar length The F600 has a very strong and high-quality collar, the dog does not have a problem wearing it and it holds well on the neck. The length of the collar is adjustable from 20 to 55 cm.
