ทำไม
Global Positioning System
ไม่ทราบที่อยู่ปัจจุบันของรถ?
▪ตรวจ
เสาสัญญาณ
GPS
ได้ถูกติดตั้งในตำแหน่งที่เหมาะสมหรือไม่
และไม่ควรติดตั้งอยู่ใต้โลหะประเภทเหล็ก
▪สัญญาณ
GPS
ไม่สามารถับได้ภายใต้อาคาร แต่
SIMTEX
Device
สามารถแจ้งตำแหน่งสุดท้ายที่รับสัญญาณได้
ทำไม
GSM
ถึงไม่สามารถติดต่อได้ หรือ โทรออกไม่ได้
ทำไมไม่โทรกลับ?
▪หาก
SIMTEX
ไม่ติดต่อมาหาเราให้ตรวจสอบว่า SIMCARD

FAQ-SIMTEX GPS Vehicle Tracking |

Troubleshooting
|
1.After the main frame of
the SIMTEX is installed, why is
there no response?
▪
Check the polarity of power
connection to see if a wrong
polarity is connected.
▪
Check the stand-by battery's
connecting wire and the main
connecting wire to see if the
connection is correct and tight.
▪
Check the fuse in the dropout
line to see if it is burnt. |
2.Why does GSM fail
to communicate?
▪
Check if the SIM card is opened.
▪
Check whether the SIM card has
password.
▪
Check if the SIM card is
correctly placed.
▪
Make sure to cut off power (plug
off the main connecting wire)
form the main frame before
pulling out the sim card.
▪
If
the vehicle is parked in a place
where the GSM signal is weak.
▪
GSM base station is crashing. |
3.Why GPS cannot calculate
the position?
▪
Check if GPS antenna is
correctly installed, or if it is
placed in a proper position.
▪
Above the GPS antenna, there
should not be any metal shield
(some heat
insulating papers or the
windshield glass may contain
metal elements).
▪
Do not park your vehicle under
shielding or a building.
▪
If necessary, put the GPS
antenna outside the vehicle
temporarily. |
4.Why does GPS
positioning take such a long
time?
The time used for positioning is
affected by many factors, such
as the weather, distribution of
clouds, roadside trees, elevated
roads, nearby high buildings,
heat insulating papers
containing metal elements, and
even the covering of the hands,
may affect the reception effect
of satellite signals.
Positioning a vehicle in an idle
stat take less time than
positioning it in motion state. |
5.Does the weather
affect GPS operation?
GPS system is able to overcome
weather problems in its initial
design. GPS satellite
positioning signals consist of
short waves; the transmission of
short waves will not be affected
by any weather conditions. GPS
signals may produce error
factors during transmission,
such as solar wind, earth
rotation, variation of
aerosphere density, building
reflection, etc. all of which
may cause deviations to GPS
short wave affect signals. But
weather factors will not affect
the normal function of GPS. |
6.Why the horn has
no sound?
▪
Check if the power line of the
horn is correctly connected.
▪
Check if the signal line of the
horn is correctly connected or
if it becomes loose.
▪
Adjust the volume of the horn. |
7.Strong echo during
communication
▪
Adjust the volume of the horn.
▪
Adjust the installation position
of the horn or the microphone;
it is better to keep them away
from each other. |
8.Frequently receive
invading alarms
▪
Adjust the sensitivity of the
supersonic detector.
▪
Before turning on the alert
state, make sure to close the
vehicle door and windows.
▪
Check if the remote controller
can normally enable and disable
the alert state. |
9.Unable to sound invasion
alarm
▪
Adjust the sensitivity of the
supersonic detector.
▪
Check if the vehicle door
open-close detecting signal wire
is correctly connected.
▪
Before turning on the alert
state, make sure to close the
vehicle door and windows.
▪
Check if the remote controller
can normally enable and disable
the alert state. |
10.The remote controller
cannot enable or disable alert
state
▪Make
sure that the indicating lamp of
the remote control receiver is
not in override mode.
▪The
remote controller battery has
insufficient power. Replace with
same sized battery.
▪The
remote controller's antenna
should keep as straight as
possible, and should not be
entangled with other wires. |
11.Unable to produce towing
alarm
▪
In alert state, it will produce
an alarm signal only after the
vehicle body is lifted up from
the ground. |
