Warnings and Notices¶
OVMS-33-7600G FCC Statement¶
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modiﬁcations to this device not explicitly approved by manufacturer could void your authority to operate this equipment.
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.
OVMS-33-7600G Specific Absorption Rate (SAR) information¶
This OVMS-33-7600G meets the government’s requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. FCC RF Exposure Information and Statement the SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types: OVMS-33-7600G has also been tested against this SAR limit. This device was tested for typical body-worn operations with the back of the phone kept 0mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain an 0mm separation distance between the user’s body and the back of the phone. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided.

Do not allow your car battery to reach 0% SOC, and if it does, plug in and charge the car immediately. Failure to do this can result in unrecoverable failure of the car’s battery.
The module can monitor the main and 12V battery and send alert notifications if the SOC or voltage drops below a healthy level.
Average Power Usage¶
The power used by the module depends on the component activation. You can save power by disabling unused components. This can be done automatically by the Power Management module to avoid deep discharging the 12V battery, or you can use scripts to automate switching components off and on.
The base components need approximately these power levels continuously while powered on:
|Component||Avg Power||12V Current|
|Base System||200 mW||17 mA|
|Wifi||330 mW||28 mA|
|Modem||170 mW||13 mA|
|GPS||230 mW||19 mA|
|Total||930 mW||78 mA|
This adds up to:
- ~ 22 Wh or 2 Ah / day
- ~ 156 Wh or 13 Ah / week
- ~ 680 Wh or 57 Ah / month
Note that depending on the vehicle type, the module may also need to wake up the ECU periodically to retrieve the vehicle status. Check the vehicle specific documentation sections for hints on the power usage for this and options to avoid or reduce this.
