13. Troubleshooting

Phenomena	Analysis	Solution
The radio cannot be turned on.	The power cord may be unconnected.	Connect the power cord properly.
The voice is unclear.	The signal may be weak.	Make sure that call participants are within the communication range.
	The volume may be low.	Increase the volume, or contact the dealer to disable the Mic AGC feature.
	The received voice is weak, discontinuous, or totally inactive. The antenna may be loosened or installed improperly.	Turn the radio off, and then reattach the antenna.
Communications group members unavailable.	The speaker may be blocked or damaged.	Clean the surface of the speaker.
	The frequency or signaling type may be inconsistent with that of other members.	Set TX/RX frequency and signaling to the same as that of other members.
	The channel type (digital or analog) may be set inconsistently.	Make sure that all members are on the same digital or analog channel.
	Users may be too far away from the group members.	Move towards other members.
There are unknown voices or noises on the channel.	The signal may be weak.	Make sure that call participants are within the communication range.
	Users may be interrupted by radios using the same frequency.	Change the frequency, or adjust the squelch level.
	The radio may be set with no signaling.	Set signaling for all member radios to avoid interference at the same frequency.
There is too much noise and hiss.	The signal may be weak.	Make sure that call participants are within the communication range.
There is too much noise and hiss.	The radio may be in an unfavorable position. For example, the signal may be blocked by tall buildings or frustrated in underground areas.	Move to an open and flat area, and then restart the radio.
The keys are unavailable.		The radio may suffer from external disturbance (such as electromagnetic interference).	Stay away from equipment that may cause interference.
The keys are unavailable.	The keypad may not work temporarily.	Restart the radio.
The LCD does not display any information.	The LCD may not work temporarily.	Restart the radio.
The GPS cannot locate the position.	The GPS module may be connected improperly.	Reconnect the GPS module.
The GPS cannot locate the position.	The radio may be at an unfavorable position, so no GPS signal is received.	Move to an open and flat area, and try again.
