GR300BT INSTRUCTION MANUAL 3
INTRODUCTION
Congratulations on purchasing your GR300BT marine radio.
For simplicity and performance, the GME GR300BT is the entertainment unit of
choice where space is limited. Using either the included gimbal mounting bracket
or an optional flush mounting kit, the flexibility and size of the GR300BT is
suited to vessels where there is insufficient space to install a conventional marine
entertainment system.
Powerful yet compact, the GR300BT combines an AM/FM radio with Bluetooth®
audio streaming that can be paired with any Smartphone, tablet or compatible
device. A front face Lanson speaker maintains audio clarity and minimises distortion.
For higher output power and full stereo sound, a pair of external speakers can be
connected using the included speaker adaptor cables.An auxiliary input socket allows
direct audio connection to media players that don’t support Bluetooth® streaming.
To ensure lasting performance, the GR300BT is waterproof to IPX7* and is UV
stabilised to maintain the finish expected of a GME radio.

COMPLIANCE
This device complies with AS/NZS 61000.6.3:2007.
This device complies with part 15 of the FCC rules. Operation is subject to the
condition that this device does not cause harmful interference.
LISTENING TO FM IN YOUR BOAT
The majority of FM broadcasts are music programs. Compared with AM signals, FM
signals have a wider dynamic range, are relatively immune to noise and provide
virtually distortion free music reproduction. However, because of the nature of FM
signals and the fact that FM stations are usually positioned for shore based reception,
reception in a moving boat may be accompanied by problems.
FM programs are broadcast for local reception and may not be heard satisfactorily at
distant locations. To enjoy FM programs at their best, it is important that you tune to
a station that is broadcasting in your locality.
FM signals can reflect from solid objects such as buildings or hills. If these reflected
signals are received along with signals that are arriving directly from the transmitter,
they may mix together to produce what is known as ‘multipath distortion’. This
distortion is heard as noise. Often, moving as little as one metre from your position
will correct this problem.
FM signals travel in straight lines. Because the signals are reflected from or absorbed
by large solid objects, a signal ‘shadow’ may be present behind the object which may
result in poor reception in that area.
