POT PCB NAME
FUNCTION
P1 M->L: Mobile to land level: Initially adjust until
mobile DTMF decodes as indicated on front
panel DTMF LED. Later, adjust for proper
mobile level as heard on telephone.
Note: DTMF can not decode unless the noise
LED is out indicating that a signal is being
received.
P2 NOISE: Noise (squelch) control: This control must be
set to minimum (fully CCW) if a COS
connection is made. If the audio input was
connected to the FM detector, advance
clockwise to a point just_beyond where the
front panel noise LED lights without any sign
of flickering.
Note: If the noise light will not come on
when the noise control is advanced, you are
not connected to the FM detector. Only the
direct FM detector output has sufficient
noise bandwidth to operate the internal noise
squelch and noise light.
P3 RPT: Repeat audio level: Set for correct repeat
audio level if repeater controller mode is
selected. (0.9.) Note: The repeat audio level
must be reset if the M->L control has been
adjusted.
P4 DTMF: Patch to mobile DTMF level: Sets the DTMF
transmitter modulation level of land to
mobile DTMF and Semi-Duplex privacy beeps.
P5 BEEPS/CW ID: Status beeps & CW ID level: Adjust for
desired modulation level of status beeps or
CW ID.
P6 TONE SIGNALLING: Tone signaling level to mobile: Adjusts the
Line In Use busy signal modulation and the
modulation level of optional signaling tones.
(Not functional unless a signaling option is
installed.)
