When battery is fully charged the indicator turns green.
The performance will be at the best condition if you remove the battery when the green
indicator is on. Then remove the power adaptor from the wall outlet.
The charger will enter the protection mode when the yellow indicator flashes, which means
the temperature or the circuit is abnormal. Do not charge the battery at this moment, just
remove the battery and turn off the power of the charger.
Notes:
* The battery is not fully charged in the factory. Before the initial use, please charge the new
battery.
KB-36C Li-ion battery of this company is adaptable with this machine.
* When you charge the battery the first time or after long time storage (2 months), several
times of charging is needed. Make sure the battery is charged at least once every three
months.
* Do not charge the battery again if it is charged fully or not in the low-pressure warning
mode, otherwise, its life will be shortened or it will be damaged. Remove the battery from
the charger after charging.
* There is a protection circuit in KB-36C battery, so the power will be cut off at too low
battery.

from other irrelevant parties who are using the same channel.
When you receive a signal that has a tone different from the one set on your radio, you will not hear the
signal. Likewise, signals that you transmit will only be received by parties whose CTCSS/DCS tones are
the same as yours.
Note: Using a CTCSS/DCS channel doesn't mean your calls are private. If other parties' CTCSS/DCS
tones are identical with yours, they can hear your calls.

Your two-way radio is designed and tested to comply with a number of national and international
standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for
occupational/controlled RF exposure environment at duty cycles of up to 50% talk-50% listen and
should be used for occupational use only. In terms of measuring RF energy for compliance with the
FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting
(during talking), not when it is receiving (listening) or in standby mode.
Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty cycle (5% talk-5%
listen-90% standby), even though this radio complies with the FCC occupational RF exposure limits
at duty cycles of up to 50% talk.
