Why do I hear unknown voices on Hytera PDC680?
If you hear unknown voices or sounds on your Hytera Radio, you may be interrupted by radios using the same frequency; change the frequency or adjust the squelch level. Alternatively, the radio may be set with no signaling; set signaling for all radios operating at the same frequency to avoid interference.
What to do if Hytera Radio cannot establish a call?
If your Hytera Radio cannot establish a call, it might be due to a weak signal. Make sure the radio is within the coverage of the BS (Base Station).
Why is the voice unclear on my Hytera Radio?
If the voice is unclear on your Hytera Radio, the signal may be weak. To resolve this, make sure call participants are within the communication range.
Why can't I use mobile data on my Hytera Radio?
If you cannot use mobile data on your Hytera Radio, the SIM card may not be working properly or is out of service due to unpaid charges; ensure the Nano SIM card works or pay the charges. The mobile data feature may be disabled for the SIM card; contact the carrier to enable it. The signal could be weak; ensure the radio is within network coverage. If both Data and WLAN are on, but the WLAN connection is unstable, turn off WLAN.
What to do if there is too much noise on Hytera PDC680?
If you are unable to hear anyone due to excessive noise and hiss on your Hytera Radio, the signal may be weak, ensure call participants are within the communication range. Alternatively, the radio might be in an unfavorable location where the signal is blocked; move to an open area and try again. Also, external disturbances could be the cause, so stay away from equipment that may cause interference.
Why I cannot communicate with group members on Hytera Radio?
If you're unable to communicate with group members on your Hytera Radio, consider the following: The frequency or signaling type may be inconsistent with that of other members, so ensure your TX/RX frequency and signaling type match. The channel type (digital/analog) may be set inconsistently; make sure all members are on the same digital/analog channel. You might be too far away from the group members; move closer. The signal could be weak, so ensure all members are within the communication range.
What to do if voice is weak during receiving on Hytera PDC680?
If the voice is weak, discontinuous, or inaudible while receiving on your Hytera Radio, consider these possibilities: The battery voltage may be low, so recharge or replace the battery. The volume might be set too low; increase it or contact your local dealer to turn the Mic AGC feature off. The antenna could be loose or improperly installed; turn off the radio, then remove and reattach the antenna. Finally, the speaker might be blocked or damaged, so clean the external surface of the speaker.
