CARE AND MAINTENANCE
10.1. General care of the device
10.1.1. When working with the device, use the supplied adapters to protect the high-frequency con-
nectors of the device from excessive wear.
10.1.2. When measuring the frequency response of active devices (amplifiers, repeaters, converters),
use external attenuators (not supplied) to prevent damage to the input circuit of the device.
10.1.3. When working, do not allow water and dust to get inside the device
10.1.4. When you have finished working with the device, turn off the device, disconnect all connected
cables and connectors. Wipe the device with a clean rag. Remove heavy dirt with a rag moistened with
soapy water. To clean the device, it is recommended to use wet wipes for household purposes. Do not
use alcohol-based or petroleum-based solvents to clean the screen and body of the device! These liquids
can damage the outer cover of the screen and the case of the product.
10.1.5. Charge the device battery according to p. 10.2.
10.2. Accumulator charging
10.2.1. To charge the device, it is recommended to use a stabilized power supply with an output volt-
age of 5 V and a current of at least 500 mA. If you cannot use such a power source, charge the instru-
ment battery from a computer or laptop.
10.2.2. Connect the supplied power cable to the mini-USB (8) connector of the instrument. Connect
the second end of the cable to the USB connector of the power supply or USB connector of the computer
(laptop).
10.2.3. Turning on the LED indicator (7)
«CHARGE»
informs about the beginning of the battery charg-
ing process. The process of charging the battery will take about 5 hours.
Note. The device is allowed to operate while charging the battery. When you connect the device, using
a USB cable to a computer or other device (laptop, tablet), the battery will start charging automatically.
10.2.4. At the end of charging, the LED indicator (7)
«CHARGE»
will turn off, informing you of the
completion of the charging process.
Note. Depending on the individual parameters of the controller built into the device battery, at the end
of charging LED indicator (7)
«CHARGE»
may not go out, and continue to glow or blink.
10.3. Battery replacement
10.3.1. After a certain period, the capacity of the Li-Ion battery is reduced, and long-term use of the
device without recharging becomes difficult.
10.3.2. Replacing the battery is necessary when the following symptoms occur:
- the battery charges very quickly and discharges very quickly;
- the battery takes a very long time to charge (more than 8 hours);
- battery does not accept charge;
- the device does not turn on offline (with the charger cord disconnected).
10.3.3. For replacement, you must purchase a new Li-Ion battery with operating voltage 3.7 V, capaci-
ty not less than 2000 mA and overall dimensions not more than: height 4 mm, length 80 mm, width 50
mm (figure 91).
Note. When purchasing and installing a battery with a capacity other than the capacity installed at the
factory, you should take into account the fact that the battery charging time will also change in a larger or
smaller direction.
