To insert a SIM card
The station manufacturer has long been lending its own SIM cards to its products for a
low monthly fee, which includes 1 MB of free data/month. The Hydro Logger H40G can
therefore be supplied with an already inserted SIM card. The operating costs of the bor-
rowed SIM card are invoiced to the station user together with the data hosting for data-
base rental and server services.
When inserting or replacing your own SIM card, please note the following:
PIN unblocking
The SIM card must be unblocked before it is inserted into the station and the
PIN code must be requested after switching on. Unblocking can be done on any
mobile phone - security function.
GSM module power off
When inserting and removing the SIM card, the GSM module must be switched
off from the power supply. This can be achieved, for example, by setting the
GSM modem permanently off in the station parameters. It is not recommended
to switch off the modem power supply by disconnecting the power connector of
the battery pack, as this may affect some previously set variables (real time of
the station, total leaked volumes, ...).
To access the SIM card holder
The SIM card is inserted into a flip-up holder located on the PCB next to the
GSM module inside the station. This PCB is mechanically connected to the plas-
tic cap of the cylindrical housing of the station. The cap is fitted with a sealing O-
ring and is not only inserted into the cylindrical outer housing of the station, but
is also secured with an M4 screw against rotation and sliding.
When opening the station, the M4 locking screw is first turned out and then the
plastic cap with the PCB is pulled out of the stainless steel casing of the station.
The two opposite holes on the sides of the plastic cap are for fixing the cap if the
stainless steel casing of the station cannot be easily removed.
Remark:
The station can be supplied either without a SIM card or with an embedded flat-rate SIM
card on long-term loan from the station manufacturer. In this case, it is a flat-rate SIM
card from O2 with the M2M tariff, which already has 1 MB of data per month free of
charge in the basic price of CZK 40. Any overrun of this volume is subsequently invoiced
at 0.03 CZK/kB of data and sent SMS at 1.35 CZK/SMS (1.50 CZK/SMS outside O2).
Invoices from the operator for the transferred data are invoiced by the station manufac-
turer to individual station operators and are subsequently re-invoiced to the station op-
erators at monthly (quarterly in the case of a smaller number of stations) intervals to-
gether with the data hosting for the rental and server services.
