HF-90 Operation & Installation Guide
When you receive an incoming Selcall/Telcall (whilst
Selcall Mute is activated), the HF-90 immediately detects
the incoming Selcall and ‘breaks’ the mute. In other words,
the volume level on the set is automatically reset to an
audible level, so that you can begin communications when
necessary.
The incoming Selcall/Telcall is then received normally, as
outlined in Sections 6.1 and 6.2 of this Guide.
If you wish to reset the Selcall Mute once you have received
a Selcall, simply repeat the procedure as outlined above.
Please note that an audio mute (squelch) facility is also available
via the Q-MAC External Mount Speaker.
Selcall Mute
The Selcall Mute function is used to mute the HF-90
receiver whilst you wait for an incoming Selcall/Telcall.
The Selcall Mute cuts out all noise on the receiver including
voice - ie. it is not selective. You can operate Selcall Mute
when the set is tuned to a particular channel or when it is in
Scan Mode.
Activating Selcall Mute
To activate Selcall Mute simply turn the VOLUME control
knob in an anti-clockwise direction, until the noise level is
diminished. The volume level on your set will remain at the
new setting until an incoming Selcall/Telcall is received.
