Garrett Z-Lynk™ Wireless Technology Z-Lynk technology is designed for a near-zero delay from your detector to your headphones. The Garrett Z-Lynk Wireless System operates with a 17-millisecond delay—six times faster than Bluetooth. This means you are hearing your target signal while the searchcoil is directly over the target, helping you to pinpoint and recover your targets more accurately. Frequency-hopping technology creates an infinite number of channels to prevent interference with nearby headphones and other wireless devices. Each Z-Lynk Wireless System Includes: WT-1 wireless transmitter WR-1 wireless receiver Two USB charging cables Mounting strap Carrying case(not shown)-1/4 headphone jack cable Compatability - Z-Lynk can be used with both VLF and pulse metal detectors. - These modules can be paired with any Garrett wireless-enabled device. This wireless system is nearly universal, designed to work with almost any brand of metal detector and almost any wired headphone. Instructions - Power On/Off—Press and hold power button ( ) for 1 second to switch ON or OFF. Note: WT-1 will switch on when it receives detector audio. Modules will automatically switch off after 10 minutes without a paired mate, or after 30 minutes of inactivity. - Volume—Adjust with WR-1 volume control buttons. If using volume-control headphones, set headphones to full volume, and then adjust WR-1 to maximum desired level. While hunting, additional adjustments can be made with headphone volume controls. - Pairing—Switch both modules on. If the pairing indicator ( ) is blinking, bring modules within 3 feet (1 meter) of each other (and away from any other Z-Lynk device), and then quickly press and release the power button on the WT-1 (TX module). Steady pairing indicators on both units indicates the units are properly paired. The modules will remain paired until you choose to pair them with another Z-Lynk device. - Recharging—Plug the supplied charging cables into the modules and any standard USB port to recharge. - LED Indicators—Battery indicator ( ) begins blinking when there are approximately 3 hours remaining. Battery indicator LED displays solid light while charging and is off when complete. Pairing indicator ( ) will blink slowly when not paired; will blink quickly during pairing search; and will remain steady when paired. - Caution—The WR-1 unit is weather resistant in light rain; the WT-1 unit will tolerate heavier rain. The Z-Lynk modules should never be submerged.
