· Please read this User Guide before installation and use.
· CAUTION: The power input voltage range for your Bluetooth®
Receiver Remote Control (referred to as Receiver) is 9V to 16V.
It is designed to work with a +12V DC battery power supply. If
your vehicle battery power output is not 12V (e.g., 24V, 36V, or
48V), you will need a voltage converter with 12V output (e.g.,
a 48V-to-12V converter). Connecting the Receiver directly to
higher voltages will cause damage to your device and VOID
THE PRODUCT WARRANTY.
· The Receiver has a Remote Turn-On Input feature; this is an
optional connection to your vehicle ignition switch so you can turn
the Receiver on or o via the ignition switch. When this input has a
signal between 12V to 56V, the Receiver will turn on. When there is
no input voltage, the Receiver will turn o.
· The Receiver’s audio outputs are pre-amplified signals that need
to be connected to a power amplifier, radio, or powered speakers
(sold separately).
· The Receiver fits in a standard Carling rocker switch opening,
which is commonly used in the dashboard of many o-road
vehicles, boats, and golf cars. The Receiver panel is waterproof;
however, the housing behind the panel is only splash proof.
· CAUTION: In order to make sure there is no potential damage to
your audio system, unplug or power o your audio equipment until
after all connections are completed.
