Raymarine Ray215 - Manual (Page 24)

3-1 Operation with a Fist Microphone
Section 3 Operation with Standard
Fist Microphone
3.1 Introduction
The RAY215 can be operated with the standard Fist Microphone, or an
optional Full Function Handset that enables additional features, or both
units to enable intercom capabilities. This section describes using the
RAY215 with the Fist Microphone. See Section 4 for a discussion of
operation using the Full Function Handset.
3.1.1 Microphone / Full Function Handset Priority
When both a Fist Microphone and Full Function Handset are in use, only
one can have priority to make a call. When the Full Function Handset is
out of its cradle, it has priority over the Fist Microphone and the REMOTE
indicator illuminates on the LCD of the base station. When the Full
Function Handset is in the cradle, the Fist Microphone has priority and
the REMOTE indicator extinguishes.
Overriding the Full Function Handset
In an emergency, the base station can override the Full Function Handset
to make a call even though the handset has priority (is off the cradle). To
override the handset, press and hold the DSC/PRI key on the base station.
The REMOTE indicator flashes and the base station regains priority
control. Make your call as usual using the Fist Microphone. On the Full
Function Handset, OVERRIDE appears on the dot matrix display. In this
mode, all keys are disabled on the handset except for DISTRESS. The
base station retains control until the DSC/PRI key is again pressed and
held.
Note: The RAY215 is designed to have the base station as the priority
unit. You should install the base station and Fist Microphone in the radio
operation room or the location from which the ship is normally navigated.
If an optional second station Full Function Handset is also installed, that
handset is the one that should be installed in the remote location.
