Two-way radio use and maintenance tips

First, the purchase and maintenance of battery

To choose a high-energy long life, small memory effect and green battery.
1. Operating temperature: -20 ° C - 60 ° C;
2. Facelift, please check battery two way radio is turned off, not the state of the radio switches plug the battery;
3. The battery takes a long time held in abeyance, first before charging the battery about 50% of electricity, which will help to prevent degradation of battery performance;
4. The first three enough power for 16 hours as possible to reduce the memory function, after the charging time to 10 hours;
5. 5/5/1990 battery (ie, 5% of signal emissions, 5% receive the signal, 90% of the reserve) is usually the case with time of 8 hours, and according to ICOM icf11 battery capacity, quality, frequency of use vary.
6. Battery life in general by the battery "charge - discharge" measured power cycles, but different standards for different brands of batteries for walkie-talkie, such as the MOTO battery is 300 times the minimum number cycles.
7. Hydride batteries for nickel-metal-media and nickel-cadmium batteries. You must ensure that each two-way radio fully charged before battery using a clean (ie, press the PTT does not work the radio transmitter). Otherwise, memory will have walkie-talkie battery. Large As shorten battery life.

Second, the remote communication

Professional flat machine, open the call the barrier of up to 5.3 km, but the transmission of two way radio waves are affected by obstructions (such as buildings, trees), while some factors tend to weaken external signal call, the call range have changed. When there is no support network, walkie-talkie up to several tens of kilometers.

Third, the choice of frequency

One of them is the band of 150MHz, and the other is the band of 400MHz. Proposal for purchase of 400 MHz band, because 400MHz frequency radio is relatively high, so that the antenna can be relatively short, or care, look more beautiful, more comfortable to use. Also in Beijing interference from more powerful 150MHz band, which seriously affects the communication distance, the same power situation, equipment is better than 400MHz communication equipment real 150MHz range.

Fourth, the screen

Some professional two-way radio with LCD display, some not, this is not absolute, the radio said with a glass display relatively high liquid level. LCD is easy crashed due to moisture, and in some designs for use in harsh environments are interested in radio through the LCD displays information such as Motorola GP328plus, machines must be regarded as relatively high range, again, no LCD screen.

Fifth, call the function

In a network (ie set the transit station) to support the case, some walkie-talkie to call the function to achieve. However, if only between the conventional single call, the function call can not be achieved.

Sixth, radiation and antennas

Antenna 5-7 cm body calls for reducing the radiation, and try not to use the antenna exposed.

It should be noted that the use of walkie-talkie:

1, when KENWOOD th78a battery power should be examined using the correct channels to avoid unnecessary mistakes.
2, the use of walkie-talkie call, the PTT should be perpendicular microphone from the mouth 5.3 cm.
3, using the intercom should avoid high temperatures, moisture, gas environment fuel gas station.
4, the use of walkie-talkie, the action in the light, do not use the site for the handheld radio antenna, is likely to cause damage to the antenna, affecting the call.
5, energy in motion, in response to lower power consumption when waiting for power.
6, the burden of the first load, preferably more than 8 hours, or affect the future of charging efficiency and battery life.
7, using the process in which the switch should not be repeated action, while the volume was adjusted to the relevant section of the location of your hearing.
8, can only be used KIRISUN Original or approved by the antenna, unauthorized or modified antennas can damage the radio or in violation of the provisions of the Radio Committee of the management industry.
9, walkie-talkie radio can not turn, use, easy damage when it launched its power management.
10, no damaged antenna used at the launch, if damage to the antenna contact with skin can cause minor burns.
11, MOTOROLA HT1000 battery should be used KIRISUN original battery or approved batteries and charger should be 50 to 40 degrees Celsius in the environment and, if more than this temperature range, the duration of battery will be affected, but may also have sufficient dissatisfaction with the rating.
12, to prevent electromagnetic interference or problems EMC caused in the new "close the walkie-talkie" logo on the occasion of the PTT switch. Such as hospitals, airports, stations Service and elsewhere.
13 walkie-talkie after her long-term use, control knobs and cabinet keys can be dirty, remove the control knob of the radio, and a mild detergent and damp cloth to clean the cabinet. The use of these detergents, alcohol, aerosols and other chemicals can damage the surface shell and the walkie-talkie.
