Chapter2. 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 it’s 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 voice prompt,
please charge the battery.
2.3 Use Caution with the Li-ion Battery
a. 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.
b. 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.
c. Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
d. 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.
e. 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.
f. Do not charge the battery or the radio if it is damp. Dry it before charging to avoid damage.
WARNING
！
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 putitinto a metal container.
6
2.4 How to Charge
a. Plug the AC adaptor into the AC outlet, and then plug the cable of the AC adaptor into the DC jack located on the back of the
charger. The indicator light blinks orange and is then readyto charge a battery.
b. Plug the battery or the radio into the charger. Make sure the battery terminals are good in contact with charging terminals. The
indicator light turns to red--- charging begins.
c. It takes approximately 2-5 hours to fully charge the battery. When the lamp lights green, the charging is completed. Remove the
battery or the radio unit with its battery from socket.
When charging a radio (with battery) the indicating lamp will not turn into green to show the fully charged status if the radio
is powered on. Only when the radio is switched off will the lamp indicate normal operation. The radio consumes energy
when itispower-on, and the charger cannotdetect the correct battery voltage when the battery has been fully charged. So
the charger will charge the battery in constant voltage mode and fail to indicate correctly when the battery has been fully
charged.

5.4 Channel selection
There are two modes of operaon: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going to be a whole lot more praccal than Frequency (VFO) mode. However,
Frequency (VFO) mode is very handy for experimentaon out in the eld. Frequency (VFO) mode is also used for
programming channels into memory.
In Channel (MR) mode you can navigate up and down the channel by using the ▲and ▼keys.
Umately which mode you end up using will depend enrely on your use case.
5.5 Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the ▲and ▼keys. Each press will increment or
decrement your frequency according to the frequency step you've set your transceiver to.
You can also input frequencies directly on your numeric keypad with kilohertz accuracy.
The following example assumes the use of a 12.5 kHz frequency step.
Example. Entering the frequency 432.6125 MHz on display A
a. Turn othe radio and press and hold the [MENU] key to turn on the radio to switch to frequency mode,
14
b. Press [EXIT/AB] unl the icon appears next to the upper display.
c. Enter [4][3][2][6][1][2][5] on the numeric keypad.
WARNING!
Just because you can program in a channel does not mean you're automacally authorized to use that
frequency. You may be tempted to use PMR446, FRS, GMRS and MURS (in USA) frequencies. Do note however
that there are restricons on these bands that make this transceiver illegal for use. Contact your local
regulatory body for further informaon on what laws, rules and regulaons apply to your area.
5.6 Channel (MR) mode
The use of Channel (MR) mode is dependent on actually having programmed in some channels to use.
Once you have channels programmed and ready, you can use the ▲and ▼keys to navigate between channels.
Note: If you have channels programmed with Transmit power set to Low, you can use the [# ]key to
momentarily switch over to mid or high power if you're having trouble getting through.
