The transmitter transmits signals at 19 kHz-31 kHz. The transmitter will enter a “sleep” mode after 15 minutes without rotation. It takes about 10 seconds to “wake up” when the transmitter is rotated. 5.2 Specifications Echo-70： Frequency: 19 kHz-31 kHz Depth Range : 60 m/190 ft@regular power 70 m/230 ft@high power Power: 3 18650 rechargeable lithium batteries 18650(3.7v)*3 battery life: 60h@regular power 15h@high power Dimensions：φ3.6*39.3(cm)/φ1.4*15.5(in) Temperature：Under 85°C(185°F) Water proof：IP67 V.BAT: 8.4v~12.6v Page/31 5.3 Digital Information Pitch: From -106% to +106% with 0.1% resolution Roll: 1-12 clock position with half hour resolution Battery: Battery full, 2/3 full, 1/3 full and flash warning Temperature: When the transmitter is overheating, temperature indication in the receivers display flashes. If temperature reaches over 85°C, transmitter may be permanently damaged. If this happens,the dot temperature indicator on the front of transmitter will turn black，ECHO70, ECHO90 and ECHO110 without the dot temperature indicator. 5.4 Transmitter Maintenance Do not place the transmitter near excessive temperature (over 85°C/185°F). Do not apply excessive pressure, shock or vibration on the transmitter. Take the battery out of the transmitter after use. Clean the spring and cap on the battery compartment when necessary. Regularly check the sealing ring on the battery cover. Replace it when necessary. Page/33 6 Battery and Charger Mag locators use rechargeable lithium batteries. This rechargeable lithium battery comes with a special charger. Any use of other lithium rechargeable battery or charger for the receiver may cause fire, explosion, leaking or other damages. Keep the battery at the normal tempera- ture of 15-25 degrees Celsius (59-77°F). Extreme high or low temperatures will short the battery life. Do not soak the battery in water or any other liquids. Do not throw the battery into fire. Do not disassemble the battery. Avoid any kind of damage to the battery. Do not discard the battery as normal trash. Please dispose of it properly. When charging the battery, red light of the charger is on. When charging is complete, a green light will be on. Please place the battery properly as shown in the diagram. 7 Warranty Underground Magnetics offers standard warranty on parts and labor of the Mag series locating system under normal usage.
