circuit) with battery and cause skin burn after the rapid temperature rise. Be cautious when
managing a charged battery, especially when you put it in the pocket, wallet or container with
metallic objects. To decrease the risk of being harmed, the battery cannot be exposed in the
file, disassembled or squeeze.
◆ The highest environment temperature around the power supply device or voltage

10.3 Radio Stun/Un-stun
Stun/Un-stun feature allows the radio to stun/un-stun the target radio through air signaling. The stunned
radio cannot transmit nor receive and it can only be activated by un-stun signaling of the authorized radio.
This feature is used to prevent from being used without authorization or used by others when lost.
10.3.1 Receiving Stun/Un-stun Signaling
After the target radio receives the stun/un-stun signaling and succeeded to be stunned / un-stunned, it will
automatically send operation success indication to the caller radio.
The radio which is stunned can only display channel alias and group alias when it returns to the home
screen without the ability to receive all the other information except the un-stun signaling. All the operation
on the radio is valid except powering on/off.
After the target radio receives the un-stun signaling and succeeded to be un-stunned, it will automatically
send operation success indication to the caller radio.
The activated radio will go back to normal from being stunned.
