Using the battery The battery is not completely charged at the factory, please charge it before using. To extend the battery life time, please power off the battery when you don't use two way radio, and save battery in a cool (temperature less than 25 2 Precautions of Charging Equipment
)and dry place. 1. Do not expose the charger to rain or snow. 2. Do not operate the charger if it has received a sharp blow, or has been dropped or damaged in any way. 3. Do not disassemble the charger if it has received a sharp blow, or has been dropped or damaged in any way. 4. Never alter the AC cord or plug provided with the unit. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician. An improper condition can result in a risk of electric shock. 5. To reduce the risk of damage to the cord or plug, pull the plug rather than the cord when disconnecting the charger from the AC receptacle. 6. To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning. 7. Use of an attachment not recommended or sold by JUSTON may result in a risk of fire, electric shock, or personal injury. 8. Make sure the cord is located so it will not be stepped on, tripped over, or subjected to damage or stress. 9. An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and/or electric shock. If an extension cord must be used, make sure that:
The pins on the plug of the extension cord are the same number, size, and shape as those on the plug of the charger. The extension cord is properly wired and in good electrical condition. The cord size is 18 AWG for lengths up to 100 feet, and 16 AWG for lengths up to 150feet. 10. Do not replace charger's power cord. If the power cord damages, you must stop using charger immediately. 3. Charging the Battery Please use the battery charger designated by to charge battery. After purchase or extended storage (more than two months), the first time to charge battery cannot make battery reach its normal operating capacity. After repeating charge /discharge it two or three times, the operating capacity will increase to its normal capacity. 4. Please Charge the Radio According to Operation Steps as Follows:
1. Insert power adapter into power supply socket. 2. Insert output terminal of power adapter into DC jack behind the charging kit, now the charging orange indicator lights about 2 seconds then goes out. 3. Insert the battery or radio equipped with battery into the charging kit. 4. Confirm the battery and charging kit terminal contact reliably, when charging indicator light turns into red and charging starts. 5. After completion of charge (charging time about 5 hours), light turns to be green. 5. Indicators Display As Following:
Status Power Connected Indicator Orange light is on about 2 seconds then goes out No battery(temperature end judges) Charge normally The battery is fully charged Fault (over temperature, battery short circuit or over discharge state) All go out Red light is on Green light is on Red light flashes Note: Before charging, please turn off radio power equipped with battery. When charging, using radio will interfere with normal charge of battery and receiver effect. Basic operations Power On/Off Turn the power switch knob clockwise to turn on radio power; to turn it off ,turn the power switch knob counter-clockwise.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The scanner receiver equipment meets the requirements of the FCC Rules, 15.121 (a) The scanner receiver in this equipment is incapable of tuning, or readily being altered, by the User to operate within the Domestic Public Cellular Telecommunications Service in Part 22. Blocking of the cellular frequencies is implemented in the firmware of the units main control central processing unit (CPU). Coverage of 824 - 849 MHz and 869 - 894 MHz is completely blocked, since it is done in the microprocessor, and cannot be re-enabled by any user-accessible procedure, including diode, resistor, or jumper changes, nor by connection of any external device such as a personal computer, nor by installation of any special enabling semiconductor device. The scanning receiver is designed so that the tuning, control and filtering circuitry is inaccessible. frequency bands allocated the to
