permitting modification of a scanning receiver to receiver Cellular Radiotelephone Service transmissions.
!
FCC LICENSE REQUIRED FOR GMRS OPERATION
The GMRS-PRO operates on GMRS (General Mobile Radio Service) frequencies, which require an FCC
(Federal Communications Commission) license. You must be licensed prior to transmitting on any of the
channels, which are comprised of GMRS channels. Serious penalties could result for unlicensed use of
these 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 these 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 trans-
mission time.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
—Re-orientate or relocate the transmitting antenna.
—Increase the separation between the equipment and transmitter.
—Connect the equipment into an electrical outlet on a circuit different from that to which the
transmitter is connected.
—Consult the dealer or an experienced radio technician for help.

FCC SAR (Specific Absorption Rate)
SAR tests are conducted using standard operating positions accepted by the FCC with the device
transmitting at its highest certified power level in all tested frequency bands, although the SAR is
determined at the highest certified power level, the actual SAR level of the device while operating can
be well below the maximum value. Before a new device is available for sale to the public, it must be
tested and certified to the FCC that it does not exceed the exposure limit established by the FCC. Tests
for each device are performed in positions and locations as required by the FCC.
Body SAR (Specific Absorption Rate)
For body worn operation, this device has been tested and meets the FCC RF exposure guidelines when
used with an accessory designated for this product or when used with an accessory that contains no
metal and that positions the handset a minimum of 10 mm (approx. 3/8 “) from the body.
Non-compliance with the above restrictions may result in a violation of RF exposure guidelines.
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

Charging and Battery Maintenance
Charging
The battery should be fully charged before initial use. Optimum battery efficiency will
be achieved after three full battery charge and discharge cycles. The radio should be
off during charging.
Follow these steps to hook up and use the charger:
1. Insert the USB cable into your power adapter (do not use the USB ports on your PC- it
may not have the needed power capabilities), and insert the other end into the
battery USB TYPE-C socket
2. Plug the AC connector of the power adapter into the main AC wall outlet.
3. Make sure that the battery and charging cable are in good contact. When the red LED
lights up, your radio is charging.
4. Once the battery's green status LED lights up, the radio is fully charged. Please remove
the radio at that time to avoid overcharging the battery.
5. Please be careful not to use fast-charging power adapters and charging cables to charge
the battery.
Battery Maintenance
The battery for your radio comes uncharged from the factory; please let it charge for at least

VISIT BAOFENGTECH.COM AND MIKLOR.COM FOR DOWNLOADS AND HELP

four to five hours before you start using your radio.
•Use only batteries approved by the original manufacturer.
•Never attempt to disassemble your battery pack.
•Do not expose your batteries to fire or intense heat
•Dispose of batteries in accordance with local recycling regulations. Batteries do
not belong in your trashcan!
Prolonging The Life of Your Battery
•Only charge batteries at normal room temperatures.
•When charging a battery attached to the radio, turn the radio off for a faster
charge.
•Do not unplug the power to the charger or remove the battery and/or radio
before it's finished charging.
•Never charge a wet battery.
•Batteries wear out over time. If you notice a considerably shorter operating
time with your radio, please consider purchasing a new battery.
•Battery performance will be reduced in temperatures below freezing. When
working in cold environments, keep a spare battery on you. Preferably inside
your jacket or in a similar location in order to keep the battery warm.

•Dust can interfere with the contacts on the battery. If necessary, wipe the
contacts with a clean cloth to ensure proper contact with radio and charger.
Battery Storage
Partially charge your battery before long-term storage in order to prevent
damage from over discharge.
While lead acid must always be kept at full charge during storage this radio uses
a lithium-based battery and should be stored at around a 40 percent charge. This
level minimizes age-related capacity loss while keeping the battery in operating
condition and allowing self-discharge.
To avoid severe capacity degradation of your battery while in long-term storage,
please cycle the battery at least every six (6) months.
Store your batteries in a cool and dry place, never above normal room
temperatures.
