Failure
Solutions
No power
●
Check cells to confirm whether cells are properly installed;
●
The cell volume may be insufficient;
●
Use AC charger to charge cells;
●
Cells may have been damaged. Change into new lithium cells.
Poor receiving signals
●
Press Up key to heighten volume;
●
The receiving signals may become weak or go beyond receiving range;
●
Check the antenna devices. In order to have the ideal effect, please place the antenna upwards.
Unable to change channels
●
In changing channels, press Menu key until the channel numbers flash on the display screen;
●
Press Up key or Down key to change channels;
●
Cell volume may be insufficient.
Limited receiving range
●
Cell volume may be insufficient;
●
In the case of any indication of insufficient cell volume, recharge the cells;
●
The effective receiving range is affected by terrain or environment;
●
The receiving range may be the greatest if it is in the open air. In the steel structured or concrete struc-
tured buildings, or the corners of streets, or factory buildings, or in cars, the receiving range will be
seriously affected;
●
Check the position of the antenna. In order to have the ideal effect, please place the antenna upwards.
Distortion of sound
●
In sending messages, your mouth must be 5 centimeters away from the microphone and talk in a
normalvoice;
●
In receiving signals, please regulate volume to an appropriate level;
●
Both talkers must keep apart by 2 meters at least or even farther;
●
The both sides may be too far away, or there is an obstacle that hinders the sending of signals. If there is
no obstacle between the two sides, the talk range is up to 7 kilometers.
