SIM CARD
Typically you will receive your Oyster with the SIM card already installed. The information below is
supplied in case you have to install the SIM card yourself or the SIM card has to be replaced.
The Oyster2 uses a Micro SIM card (form factor 3FF). The SIM holder is on the underside of the control
board so the control board will have to be removed/lifted out of the housing to insert/swap the SIM.
CAUTION: When handling the control board take steps to prevent static discharge which could render
the device inoperable. DO NOT touch the GPS antenna.
Slide the SIM card into the holder with the keyed corner first and the SIM contacts orientated down to
the main board.
BATTERIES
The Oyster2 uses 3 x 1.5 V Lithium or 3.6 V Lithium Thionyl Chloride (LTC)
Spiral Type
AA batteries.
(Bobbin Type LTC may not supply enough peak current).
Note: The Oyster2 does not have reverse
voltage protection so take care to insert the batteries with the correct polarity
–
the springs are the
negative terminals.
