Battery Charging and External Power
The supplied wall transformer and cable will charge a fully discharged receiver in approximately 5 hours, 20% per hour.
Only the Type-C connector charges the internal batteries.
The round external power connect does not charge the internal batteries; however, the receiver will run off external
power indefinitely, switching to the internal battery when external power is removed.
It is possible to purchase reasonably priced external power cables either from Amazon or iGage. See

Radio Notices
FCC Notice: i83 GNSS receivers comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules
when it is used in the Portable Mode.
Operation is subject to the following two conditions:
The device may not cause harmful interference.
The device must accept any interference received, including interference that may cause undesired operation.
FCC Compliance:
Bluetooth Radio
Radiated output power from the internal Bluetooth radio is far below FCC radio frequency exposure limits. The
Bluetooth radio operates within guidelines for radio frequency safety standards and recommendations, which reflect
the consensus of the scientific community.
The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile
phones. However, the use of wireless radios may be restricted in some situations or environments, such as on aircraft or
near blasting areas.
UHF Radios
Every i83 GNSS receiver includes a 2-watt Tx/Rx radio capable of broadcasting UHF radio transmissions.
UHF Safety and General Information
When used in the transmitting mode, even though the broadcast power is relatively low, you should take these
additional precautions:
Medical Devices - Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you may want to
consult your hearing aid manufacturer to discuss alternatives.
Medical Devices - Pacemakers
The Advanced Medical Technology Association recommends that a minimum separation of 6 inches (15 cm) be
maintained between a handheld wireless radio and a pacemaker. These recommendations are consistent with the
independent research by, and recommendations of the U.S. Food and Drug Administration.
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 cm) from their pacemaker when the radio is turned ON.
