2 Precautions of Charging Equipment
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.

5. Indicators Display As Following:
Status Indicator
Power Connected Orange light is on about 2 seconds then goes out
No battery(temperature end judges) All go out
Charge normally Red light is on
The battery is fully charged Green light is on
Fault (over temperature, battery short
circuit or over discharge state)

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.
Volume Control
Turn the volume switch knob clockwise to increase volume; to decrease the
volume, rotate the volume switch knob counter-clockwise.
RX
When radio receiving information ,green LED lights .
1) Only same signaling and CTCSS setting can receive information .
2) May not receive any calling if radio is at lower signal and set high level SQL.
3) Local dealer maybe program your radio with CTCSS/DCS . Users can receive the same
signaling information if chosen channel with CTCSS/DCS . Or it can not get any calling .
