GMRS Communication
This GMRS (General Mobile Radio Service) feature is a land-mobile service available for short-distance, two-way
communications in the USA. You must have a valid FCC license to communicate on these channels. The GMRS/FRS
frequencies that radio this radio uses are set aside for communicating with others while hiking, biking, and working; keeping
track of family and friends at a crowded public event; checking with travel companions in another car; talking with neighbors;
arranging meeting spots with others while shopping at the mall. Licensed users will be issued a call sign by the FCC, which
should be used for station identification when operating this radio. GMRS users should also cooperate by
engaging in
permissible transmissions only, avoiding channel interference with other GMRS users, and being prudent with the length of
their transmission time.
FCC License Required
This two-way radio operates on GMRS (General Mobile Radio Service) frequencies which require an FCC (Federal
Communications Commission) license. A user must be licensed prior to transmitting on the GMRS band with this radio.
Serious penalties could result for unlicensed use of GMRS channels, in violation of FCC rules. Operation of this radio is
subject to additional rules specified in 47 C.F.R. Part 95. For licensing information and application forms, please call the FCC
Hotline at 800418-FORM. Request form #159 and form #605. Questions regarding the license application should be directed

2. BATTERY INFORMATION
2.1 Charging the Battery Pack
The Li-ion battery pack is not charged at the factory; please charge it before use.
Charging the battery pack for the first time after purchase or extended storage (more than 2 months) may not bring the battery pack to its
normal maximum operating capacity. Best operation will require fully charging/discharging the battery two or three times before the operating
capacity will reach its best performance. The battery pack life may be depleted when its operating time decreases even though it has been fully
and correctly charged. If this is the case, replace the battery pack.
2.2 Charger Supplied
Please use the specified charger provided by Radioddity. Other models may cause explosion and personal injury. After installing the battery
pack, and if the radio displays low battery with a red flashing lamp or voice prompt, please charge the battery.
2.3 Use Caution with the Li-ion Battery
(1) Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery pack, as Radioddity
cannot be held responsible for any accident caused by modifying the battery.
(2) The ambient temperature should be between 5℃-40℃ (40˚F - 105˚F) while charging the battery. Charging outside this range may not fully
charge the battery.
(3) Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
(4) To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until the green light is
on.
(5) Do not recharge the battery pack if it is fully charged. This may shorten the life of the battery pack or damage the battery pack.
(6) Do not charge the battery or the radio if it is damp. Dry it before charging to avoid damage.
NOTICE
When keys, ornamental chain or other electric metals contact the battery terminal, the battery may become damage or injure a human. If
the battery terminals are short circuited it will generate a lot of heat. Take care when carrying and using the battery. Remember to put the
battery or radio into an insulated container. Do not put it into a metal container.
2.4 How to Charge

6.2 DTMF
DTMF is an in-band signaling method using dual sinusoidal signals for any given code. Originally developed for telephony systems, it has proved
a very versatile tool in many other areas.
In two-way radio systems, DTMF is most commonly used for automation systems and remote control. A common example would be in amateur
radio repeaters where some repeaters are activated by sending out a DTMF sequence (usually a simple single-digit sequence).
DTMF frequencies and corresponding codes
1209Hz 1336Hz 1477Hz 1633Hz
697Hz 1 2 3 A
770Hz 4 5 6 B
852Hz 7 8 9 C
941Hz * 0 # D
The radios has a full implementation of DTMF, including the A, B, C and D codes. The numerical keys, as well as the and keys
correspond to the matching DTMF codes. The A, B, C and D codes are located in the [MENU], , and [EXIT] keys respectively.
To send DTMF codes, press the key(s) corresponding to the message you want to send while holding down the PTT key.
In general, there are two forms of selective calling in two-way radio systems: Group call, and Private call.
Group call, 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.
Private call, 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.
6.3 Dual Watch
In certain situations, the ability to monitor two channels at once can be a valuable asset. This can be achieved in one of two ways. You can either
have one receiver in your radio and flip-flop between two frequencies at a fixed interval (known as Dual Watch), or you can equip a radio with
-21-

two receivers (known as Dual Receive or Dual VFO). The former method is cheaper to implement and far more common than the latter.
The radio features Dual Watch functionality (single receiver) with the ability to lock the transmit frequency to one of the two channels it
monitors.
Enabling or disabling Dual Watch mode
(1) Press the [MENU] key to enter the main menu.
(2) Enter 3 on the numeric keypad to get to Radio Settings.
(3) Press the [MENU] key to confirm, enter 15 on the numeric keypad to get to 15 Dual Watch.

·
Repeat the above operation, select "OFF", the dual watch function is disabled, and the icon 'D' on the top line of the screen disappears.
Note: When the dual watch function is turned on, the icon 'D' is displayed on the screen, and the "Singal Mode" submenu is automatically
shielded in the radio setting menu.
After the dual watch is turned off, the radio setting menu will automatically add "Singal Mode". After turning on the single display mode, the
radio will display the channel name, frequency and channel sequence on the same screen.

Verify that your TX/RX frequency and signaling type
are correct.
You may be too far away from other members. Move towards other members.
You hear unknown voices or noise.
You may be interrupted by radios using the same
frequency.
Change the frequency, or adjust the squelch level.
The radio in analog mode maybe set with no signaling. Request your dealer to set signaling for the current
channel to avoid interference
You are unable to hear anyone
because of too much noise and hiss.
You may be too far away from other members. Move towards other members.
You may be in an unfavorable position. For example, your
communication may be blocked by high buildings or
blocked in an underground area.
Move to an open and flat area, restart the radio,
and try again.
It may be the result of external disturbance (such as
electromagnetic interference).
Stay away from equipment that may cause
interference.
The radio keeps transmitting.
VOX may be turned on or the headset is not installed in
place
Turn off the VOX function. Check that the
headphones are in place.
NOTE: If the above solutions cannot fix your problems, or you may have some other queries, please contact your dealer
