Battery Information
Initial Use
New batteries from the factory are not fully charged, so be sure to charge a
new battery for at least 5 hours before initial use. Three full charge-discharge
cycles would optimize the capacity and performance of your battery. When
battery power runs low, it is time to recharge or to replace the battery.
Applicable Battery Packs
Please only use the battery specied by Hytera. Other batteries may burst,
causing bodily injury and property damage.
Caution:
1. Do not dispose of the battery in fire!
2. Recycling and disposal of the battery shall comply with your local
regulations.
3. Never attempt to dismantle the battery.
Note:
1.Chargethebatteryatatemperatureamong5℃ -40℃ .Violation
of the said limit may cause battery leakage or even damage.
2. When charging the battery that is attached to a radio, turn the
radio off to ensure a full charge.
3. Never charge a wet battery or a wet radio with battery attached.
Please dry it with a soft cloth prior to charge.
4.The battery will eventually wear out. When the operating time
of a fully charged battery is noticeably shorter than its normal
performance, you need to buy a new one. Please replace it ASAP.
5. If the product shuts off automatically due to low battery, please
charge the battery soon, or the battery could suffer damage.
6. If you plan not to use the radio for a long time, please remove
the battery from it to avoid any unexpected damage.

7
Battery Information
7. Do not charge fully charged batteries for an “extra boost”. This
action will significantly reduce battery life.
8. Do not insert the radio or battery into the charger when it
doesn’t need to be charged, because continuous charging will
shorten the battery life. Note: Never use a charger to hold the
radio.
To Prolong Battery Life
1. Battery performance will decrease greatly at a temperature below 0℃.
Therefore, a spare battery is necessary in cold weather. However, the
replaced battery that fails to function at a low temperature may work at
room temperature, so keep it in place for later use.
2. The dust on the battery contact may make the battery work or charge
abnormally. Please use a clean and dry cloth to wipe the contacts before
charging or attaching the battery to the radio.
Battery Storage
1. If you plan to store a battery for a long time, please fully charge it rst to
avoid battery damage due to over-discharge.
2. To avoid battery capacity reduction due to over-discharge, recharge a
battery after storing it for a certain period of time: 6 months for Li-Ion & Li-
polymer batteries.
3. Store your battery in a cool and dry environment at room temperature to
reduce self-discharge.
Charging the Battery
When the Status Indicator ashes red, and an alert tone sounds at intervals of
ten seconds indicating the battery power runs low, please charge the battery
immediately. Only use the charger specied by Hytera. The Charge Indicator
will indicate the charging progress.

8
Battery Information
Please follow steps below to charge the radio with switching power:
1. Plug the AC connector of the switching power into an AC outlet socket.
2. Plug the Mini USB connector of the switching power into the Mini USB port
at one side of the radio unit.
3. Make sure that the battery is in good contact with the switching power. The
charging process begins when the Charge Indicator at one side of the radio
unit glows orange.
4. When charging is completed, the Charge Indicator glows green. Then you
may remove the radio.

Programmable Auxiliary Functions
●Squelch Off Momentary
●Battery Strength
●Channel Lock (When this function is enabled, your current operating
channel will remain unchanged even if you rotate the Channel Selector
Knob. And this feature always remains valid after PC programming.)
Advanced Operations
The following functions can be programmed via programming cable and CPS
software. Contact your retailer for additional information.
CTCSS/CDCSS
You may set up talkgroups with unique CDCSS/CTCSS to prevent unwanted
conversations at the same frequency. If CTCSS/CDCSS is set on the current
channel, CTCSS/CDCSS match is required for the radio to unmute to an
incoming signal. If CTCSS/CCSS is not set, the radio can receive calls from all
users operating at the same frequency.
This feature does not mean that your conversation will not be heard by others.
Radios with the same CTCSS/CDCSS or with no CTCSS/CDCSS can also
receive calls from you.
Battery Save
This feature can reduce power consumption (enabled by your dealer).
If the radio is not operated (no key-press or knob-rotation) in Standby status,
it will automatically enter Battery Save mode upon expiration of a preset time
(30 seconds by default via programming software). The radio may exit the
Battery Save mode and get activated once any key is pressed or any signal is
received.
Time-out Timer (TOT)
This feature can prevent users from transmitting on a channel for an extended
period of time, and protect the radio from damage caused by prolonged
transmission. If the preset time expires, the radio will automatically terminate
transmission and keep beeping until the PTT key is released.
A pre-alert function to warn you of the TOT expiration in advance can be
programmed via programming cable and CPS software.

16
Advanced Operations
Battery Strength Indicator
When you intend to know the battery strength, press the programmed Battery
Strength Indication key to illuminate the Status Indicator and learn the battery
strength by different colors. To exit this function, release the key.
Status Indicator of different colors represents different battery strength levels.
Refer to the table below:
Battery Strength Status Indication
70% - 100% Solidly glows green.
50% - 70% Solidly glows orange.
30% - 50% Solidly glows red.
10% - 30%
There is no indication upon press of the programmed
Battery Strength Indication key. However, the
indicator keeps ashing red in operation status.
Less than 10%
There is no indication upon press of the programmed
Battery Strength Indication key. However, the
indicator keeps flashing red in standby status and
keeps sounding a low-pitched tone at an interval of 10
seconds. If you press PTT at this time, the radio will
sound an alarm sound to warn you of the transmission
inhibition.
Monitor
●Squelch Off
Purpose: In this mode, the speaker is unmuted in any condition so as to
receive any sound on the current channel. When audio signal is received on
the channel, audio will be heard. Otherwise, background noise will be heard.
Operation: Press the Squelch Off key to enter this mode, and press it again to
exit.
●Squelch Off Momentary
Purpose: Refer to Squelch Off.
Operation: Hold down the Squelch Off Momentary key to enter this mode,
and release the key to exit.
