10.Notes for Care and Maintenance
To ensure proper usage and extend service life of the in-Vehicle terminal,
the following should be paid attention to in the course of installation, use,
care and maintenance:
1) The voltage range of normal power supply for the in-Vehicle terminal is
DC 9V—36V, and the recommended operating voltage is12V or 24V.
Prior to installation, the user shall make sure if the power system falls
within the range aforesaid.
2）When the in-Vehicle terminal is powered on, do not plug in or pullout
the antenna or remove SIM card to avoid damage to the in-Vehicle terminal
and SIM card.
3）The connection socket of the in-Vehicle terminal shall avoid direct
contact with conductive body, otherwise it may result in short circuit and
danger.
4）Do not use the in-Vehicle terminal in an environment where there is
much dust. When washing the vehicle, try to prevent the terminal from being
soaked or showered to avoid damage to the terminal.
5）Keep using the in-Vehicle terminal in normal temperature. The
equipment may be damaged when operating for long in an environment
where the temperature is above 85℃ or lower than -40℃.
6）When the vehicle is inside building, tunnel or within a shielded area,
receiving of GPS signals and GSM communication network signals will be
affected. After the vehicle moves out of the area mentioned above, receiving
of GPS signals and GSM network will automatically resume
7）The main unit has built-in spare battery which will not be activated and
begin working until the equipment is used for the first time and supplied with
external power. After the battery is activated, the equipment will, when the
external power supply is cut off, automatically switch to operate with power
supply from the built-in battery, and the operation can last for about 10 hours
(calculated based on that the terminal data transmits once every 5 minutes).
8）The terminal equipment can use the accessories designated or
recognized by CASTEL only. Unauthorized accessories may damage the
terminal equipment.
9）If abnormality occurs to the terminal equipment or its accessories, thus
leading to failure of normal operation, please contact the manufacturer or the
local dealer.
