Two way radio use and maintenance tips
First, the battery purchase and maintenance
To choose a high energy, long life, small and green memory effect the battery.
1. Operating temperature: -20 ° C – 60 ° C;
2. Facelift, please check the two way radio battery is turned off, do not state the radio is switched plug the battery;
3. Battery takes a long time kept on hold, first pre-charge the battery about 50% of electricity, which will help prevent battery performance degradation;
4. The first three charge sufficient for 16 hours as possible to reduce the memory function, after the charging time to 10 hours;
5. Battery 5-5-90 (ie 5% of the emission signal, 5% receive the signal, 90% of the standby) is generally the case with time of 8 hours, and depending on 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 walkie-talkie batteries, such as the MOTO battery is 300 times the minimum number of cycles.
7. For the average nickel-metal hydride batteries and nickel-cadmium batteries. Must ensure that each two way radio before charging the battery completely using a clean (ie press the PTT key is not functioning radio transmitter). Otherwise, it will have walkie-talkie battery memory. Greatly shorten the battery life.
Second, the communication distance
Professional machine flat, open up the call from the barrier up to 3-5 km, but the transmission of two way radio waves will be affected by obstructions (such as buildings, trees), will the same time, some external factors tend to weaken the call signal, the call range will have changed. When there is network support, the walkie-talkie calls from up to several tens of kilometers.
Third, the choice of frequency
One is the 150MHz band, and the other is the 400MHz band. Proposed purchase of products 400MHz band, because the frequency of 400MHz the radio is relatively high, so the antenna can be made relatively short, or carefully, look more beautiful, more convenient to use. Also in Beijing, more powerful 150MHz band interference, seriously affecting the communication distance, the same power situation, 400MHz equipment is better than the actual communication range 150MHz equipment.
Fourth, the display
Some professional two way radio with LCD display, some do not, this is not absolute, said the radio with a relatively high-end liquid crystal display. LCD is easy crashed because of damp, and in some designs for use in harsh environments are interested in radio through the LCD screen does not display information, such as MOTOROLA GP328plus, should be regarded as relatively high-end machines, again, no LCD screen.
Fifth, call function
In a network (ie set up 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 from the body 5-7 cm calls to reduce the radiation, and try not to use the exposed antenna.
Should be noted that the use of walkie-talkie:
1, when KENWOOD th78a battery power should be examined using the correct channels in order to avoid unnecessary mistakes.
2, the use of walkie-talkie call, the PTT should be maintained perpendicular to the microphone away from the mouth 3-5 cm.
3, using the intercom should avoid high temperature, moisture, combustible gas environment away from the gas station.
4, the use of walkie-talkie, the action to light, do not use hand-held radio antenna site, this is likely to cause damage to the antenna, affecting the call.
5, the launch power consumption, answering small power consumption when waiting for power.
6, charging the first charge, preferably more than 8 hours, or affect the future of the charging efficiency and battery life.
7, the use of the process where the switch should not be repeated action, while the volume was adjusted to the appropriate section of the location of your hearing.
8, can only use KIRISUN Original or recognized by the antenna, unauthorized or modified antennas could damage the radio or in breach of the provisions of industrial Radio Management Committee.
9, walkie-talkie radio can not twist, use, easy to damage when it launched its power management.
10, do not use the damaged antenna, in the launch, if the damage to the antenna contact with the skin may cause minor burns.
11, the MOTOROLA HT1000 Battery must use KIRISUN original battery or approved batteries, and charger should be 5-40 degrees Celsius in the environment and, if more than this temperature range, the battery life will be affected, but also there may be sufficient dissatisfaction with the rated capacity.
12, to avoid electromagnetic interference or electromagnetic compatibility problems caused, in the posted “close the walkie-talkie” logo of the occasion Switch PTT off. Such as hospitals, airports, gas stations and other places.
13, walkie-talkie after long-term use, control knobs and cabinet keys can easily become dirty, remove the control knob from the radio, and with a neutral detergent and a damp cloth to clean the cabinet. Use of such detergents, alcohol, aerosol sprays and other chemicals can cause damage to the shell surface and the walkie-talkie.
