Geospace Seismic Recorder with Internal Battery (GSB)
USER MANUAL
7007 Pinemont
Houston, TX 77040 USA
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Geospace Technologies declares that the radio equipment type IEEE 802.15.4 Radio is in compliance with Directive 2014/53/EU. The
full text of the EU declaration of conformity is available at the following internet address.
http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32014L0053
Operating frequency range：2405~2480MHz; Max. tune-up power with tolerance：0±1.0dBm
CAUTION: Any changes or modifications to this device not explicitly approved by the manufacturer could void your authority to operate this
equipment.
FCC
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and
operated with a minimum distance of 20cm between the radiator and any part of your body.

Industry Canada
(English)
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device
may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the
device.
(French)
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée
aux deux conditions suivantes : (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
IC RF Radiation Exposure Statement:
(English)
This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be
installed and operated with a minimum distance of 20cm between the radiator and any part of your body.
(French)
Pour se conformer aux exigences de conformité CNR 102 RF exposition, une distance de séparation d'au moins 20 cm doit être maintenue entre
l'antenne de cet appareil ettoutes les personnes.
Deployment
The GSB should be deployed with the metal plate down. This provides sufficient earth grounding and
maximum cooling of the unit as well as providing the GPS receiver in the top to the unit with an ideal
“view” of the satellite constellation. The unit should be transported on its side in order to put the unit into
standby mode and minimize battery consumption prior to use. Once the unit is ready to be deployed it
should be flipped plate down and the GSB will immediately begin power on self-test.
The GSB will test all of its internal circuits followed immediately by an impedance test of the seismic
sensors. The LED that can be seen from the top of the GSB will flash codes to indicate the GSB’s
condition. The GSB will enable the Global Positioning System (GPS) receiver and begin to flash the
code that indicates that it is searching for satellites. Within a few seconds the GPS receiver will have
sufficient satellite information to obtain a 3 dimensional fix. The flash code will change to indicate this
condition and the GSB will now begin to acquire seismic data if it has been programmed to begin
recording immediately. See Programming below. After several minutes the internal GSB clock will be
sufficiently disciplined and the GPS receiver will be turned off. The flash code will again change to
indicate this state. See the flash codes below.
Radio Status Monitoring
A GSB may be connected to a laptop computer and used as a hub to monitor the status of any GSBs
within a 50m to 100m radius via a high frequency radio link. In this mode the laptop/hub monitors and
logs status information from all of the GSBs that it communicates with. The laptop stores the GPS
location, acquisition status, temperature, battery status and the nonvolatile memory status of each GSB.
By moving the hub throughout the seismic spread all of the GSBs in the survey may be monitored and
logged. This logging may take place during acquisition of seismic data with no adverse effect on the data
quality.

Downloading
The GSB non-volatile memory may be read and cleared by removing the battery connection and
inserting the unit into one of the outlets in the GeoReaper. See the GeoReaper User Manual for
further instruction.
Programming
The GSB recording parameters such as sample rate, pre-amp gain, record mode, and testing, are
programmed and stored in non-volatile memory in the GSB by the GeoReaper. See the
GeoReaper User Manual for further instruction.
