It is VERY Important to NOT transmit without a antenna or dummy load attached to the mobile radio. Doing so, will cause harm to the internal components of your radio. You will want to choose a suitable antenna for the bands you plan on transmitting and receiving on. If you plan on transmitting on 145MHz you will want to ensure you have picked an antenna that states it is capable of working with 145MHz. If an antenna is not properly tuned for the frequency you transmit on it can cause damage with the reflected power going back into the radio. Pick an antenna with SWR of less than 1.5:1 to safely transmit. Grounding Plane:
Antennas require an appropriate grounding plane to properly work:
Magnetically Mounted Antennas:
GMRS-50X1 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 15 These antennas must be grounded to a metal surface, such as a vehicle body. Magnetic base antennas do not properly operate unless they are fully magnetically grounded first. NMO or PL-259 Base Antennas:
These antennas will normally require a base or mobile hardware kit. These kits are grounded either through: drill or clamp inserts on vehicles, magnetically mounted, or available as stationary base hardware kits. Some antennas may include a base station grounding plane kit. Antenna Requirements Antenna SWR Rating: 1.5:1 or less (on the radio frequencies in use.) Antenna Impedance: 50 ohm (use 50 ohm rated coax and coax connectors) Antenna Grounding: Ensure the antenna is mounted with a grounding plane Visually Inspect Coax/Connectors for any Slits or Damage moisture should not be allowed to penetrate fittings or your coax To maximize the life of your radio, it is important to understand antenna basics before transmitting on your radio, transmitting without an antenna, or with high SWR (Standing Wave Ration) can void warranty support. 16 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP An Active SWR Meter is a great tool to have when selecting an antenna for your needs. You can monitor and confirm that your SWR is within safe levels when setting up your radio for the first time (periodically checking SWR and your antenna set-up is advised) NOAA Weather Channels To add your local NOAA Weather channel a new scanning channel, start by switching your radio to Frequency (VFO).

You must be licensed prior to transmitting on all channels, which comprise of GMRS channels. Serious penalties could result for unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Communications Act's Sections 501 and 502 (amended). You will be issued a call sign by the FCC, which should be used for station identification when operating the radio on GMRS channels. You should also cooperate by engaging in permissible transmissions only, avoiding channel interference with other GMRS users, and being prudent with the length of your transmission time. To obtain a license or ask questions about the license application, contact the FCC at 1-888-CALL FCC or go to the FCC's website: http://www.fcc.gov and request form 605. Or you can apply online direct for a GMRS license (http://wireless.fcc.gov/uls/ ) a guide for this can be found at: http://alcornema.com/gmrslisenceinfo.htm 20 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP GMRS Frequency Chart, Channel Guide GMRS FREQUENCY CHART CH: Name Ch.

GMRS-50X1 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 23 Making a call Press and hold the PTT button on the side of the handheld mic to transmit. While transmitting, speak approximately 3-5cm (1-2 inches) from the microphone. When you release the PTT your transceiver will go back to its receive mode. Channel selection There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode. For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency
(VFO) mode. However, Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also used for programming channels into memory. For details on how to program your transceiver see Chapter 4, Programming. Ultimately which mode you end up using will depend entirely on your use case. Frequency (VFO) mode In Frequency (VFO) mode you can navigate up and down the band by using the keys (or rotating the selector knob). Each press (or rotation click) will increment or decrement and 24 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP your frequency according to the frequency step you've set your transceiver to (Menu Item 1:
Step) You can also input frequencies directly on your numeric keypad with kilohertz accuracy. However, the radio will floor to the nearest frequency that corresponds to your frequency step, in other words, when you input frequencies with greater than 1kHz resolution (such as 145.6875 MHz in the example below), always round your input up. Just because you can program in a channel does not mean you're automatically authorized to use that frequency. Transmitting on frequencies you're not authorized to operate on is illegal, and in most jurisdictions a serious offence. If you get caught transmitting without a license you can and will get fined, and in worst case sent to jail. However, it is legal in most jurisdictions to listen. Contact your local regulatory body for further information on what laws, rules and regulations apply to your area. Channel (MR) mode GMRS-50X1 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 25 The use of Channel (MR) mode is dependent on actually having programmed in some channels to use. To find out more on how to program channels see Chapter 4, Programming. Once you have channels programmed and ready, you can use the between channels (or Rotate the Selector Knob) keys to navigate and If you have channels programmed with Transmit power set to Low, you can use the key to momentarily switch over to high power if you're having trouble getting through. Monitor Both VFO & MR Modes You can toggle from VFO and MR (Memory Recall) mode by either pressing the V/M button on the front of your radio, or you can toggle modes from the Handheld Mic by a long press of the Menu button. The VFO/MR mode will only toggle on the current selected A/B/C/D line while the other channel lines will remain on channel or memory mode as they were selected.

To minimize this problem, several methods of blocking out unwanted transmissions on your frequency have developed. In general, there are two forms of selective calling in two-way radio systems: Group calling, and individual calling. Group calling, as the name suggest, is a one-to-many form of communication. Every radio in your working group is configured the same way and any radio will make contact with every other radio in the group. Individual calling, some times also known as paging, is a one-to-one form of communication. Every radio is programmed with a unique ID code. And only by sending out a matching code can you get that radio to open up to your transmissions. The BTECH X-SERIES MOBILES features three additional ways of group calling

CHAPTER 8 REPEATERS CHAPTER 9 CUSTOMIZATION 56 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP Chapter 8. - Repeaters A radio repeater is an automated transceiver in a fixed location. Usually mounted high up on hilltops or on tall buildings, but sometimes they operate within buildings for internal use. A repeater takes one signal and relays it, usually after amplifying it by orders of magnitude. Whether you're a commercial (business or government) user or an amateur radio operator, chances are you'll be dealing with a repeater system sooner or later. To find out what settings to use to use your local repeater, ask your employer or someone at your local amateur radio organization for details. A common type of repeater is the duplex repeater. In a duplex repeater system, the repeater transmits and receives simultaneously, but on different frequencies. To utilize this type of repeater, your radio has to be capable of transmitting and receiving on different frequencies on the same memory channel. How you use this kind of repeater is by setting the receive frequency of your radio to the output frequency of the repeater, and the transmit frequency of your radio to the input frequency of the repeater. Often times, the transmit frequency to use isn't explicitly stated, but rather an offset relative your receive frequency is specified. This is conveniently by specifying offset rather than transmit frequency. (Example 145.000MHz Receive GMRS-50X1 VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP 57 with .600MHz transmit is a transmit Channel of 145.600MHz) SFT-D and OFFSET only function in VFO mode.

If you're experiencing problems making a connection to the repeater, check your settings and/or go through the procedure again. If you're still unable to make a connection, contact the person in charge of the radio system with your employer or your local amateur radio club, as the case may be. If you for some reason want to listen to the repeater's input frequency instead, press momentarily and you'll reverse your transmit and receive frequencies. This is indicated in the LCD on the radio with an R in the top row, next to the + and - for the offset direction.

Some general rules for antenna location that can aid radio performance. 1. Metal surfaces covered by fiberglass or vinyl may affect radio range. Avoid these locations. 2. Mount the antenna as high on the vehicle as possible. The higher the better. 3. If possible, mount the antenna in the center of whatever surface you choose. 4. Be sure the mounting location will allow for connection of the cable to the radio. 5. Be sure the mounting location is clean and dry before installing the antenna. 6. Route the antenna cable through an accessible entry point, such as a rear door or trunk opening. 7. When routing the antenna cable inside the vehicle, keep the cable away from noise sources, such as the ignition system, gauges, etc. 8. Exercise care to prevent cable damage. Make use of existing gaskets, grommets and weather stripping to protect the cable along its route. 9. The consumer must maintain a minimum safe separation distance of 104.7cm from the antenna when transmitting.

BTECH (BaoFeng Tech) 702 N Industrial Ave Arlington South Dakota United States 57212 Date: 26 February 2019 PHOENIX TESTLAB GmbH Product Certification Knigswinkel 10 D 32825 Blomberg FCC ID: 2AGND50X1G Subject: Declaration of compliance to the requirements of 15.121 We declare that, this scanning receiver is incapable of operating (tuning), or readily being altered by the users to operate, within the frequency bands allocated to the Cellular Radiotelephone Service in part 22 of this chapter (cellular telephone bands). This device will not be able to receive transmissions in the cellular telephone bands by means of clipping the leads of, or installing, a simple component such as a diode, resistor or jumper wire; replacing a plug-in semiconductor chip; or programming a semiconductor chip using special access codes or an external device, such as a personal computer. This device is also incapable of converting digital cellular communication transmissions to analog voice audio. This device is designed so that the tuning, control and filtering circuitry is inaccessible. Any attempts to modify the equipment to receive transmissions from the Cellular Radiotelephone Service will render the receiver inoperable. This scanning receiver rejects any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. We are aware that the modification of this device to receive transmissions from Cellular Radiotelephone Service frequency bands will be considered to constitute manufacture of such equipment. This includes any individual, individuals, entity or organization that modifies one or more scanners. Any modification to receive transmissions from the Cellular Radiotelephone Service frequency bands voids the certification of the scanning receiver, regardless of the date of manufacture of the original unit. If you have any questions, please feel free to contact me. Thank you. Sincerely, Signatory BTECH (BaoFeng Tech) Contact person: Greg Wilson
