About This Manual; Simnet Network System; Bluetooth - Simrad WR20 RemoteCommander Manual

WR20 Remote Commander
Note
The way that Bluetooth operates means that the maximum distance
between the WR20 handset and its base station is less when using
the handset in audio mode (VHF, intercom or mobile phone modes)
than for data communication. In addition the Bluetooth signal
strength is heavily attenuated by the human head and is optimized
when the handset is in line of sight of the base station

1.4 Bluetooth

Bluetooth is the name of a wireless technology standard for
connecting devices without the need for cables. It provides a
reliable means of data and audio communication between the
remote Handset and a fixed Basestation.
Note
The separation distance between the Handset and Basestation can
generally be greater for data communication compared with that of
audio communication.
Note
Bluetooth and WiFi technologies operate in the same part of the
radio spectrum. As with any Bluetooth enabled devices working in
a WiFi environment interference can occur. Caution is therefore
10
depending on how the handset is held
