9. SEND FUNCTIONS AND PARAMETERS
The AM5(e) Classic contains a highly-flexible signal generator that is capable of
generating a variety of test tones. The labels for the LEDs above the right SEND key are
different for the AM5 Classic and the AM5e Classic. The front panel areas for SEND
functions are shown below:

This section describes all the send functions and parameters in the order they are
selected by each press of the SEND keys. Unless otherwise specified, the descriptions
apply to both the AM5 Classic and the AM5e Classic. Views of the LED indicators and
displays showing typical readings are provided. A lighted LED is shown by shading,
as shown by above defaults.
If the LINE selection is 4W, 2W, or 2W +2.16µf, the signal generator will output from
the TX/2W jack (or T and R terminals). If the LINE selection is 4W REVerse, the signal
generator will output from the RX jack (or T1 and R1 terminals). For any LINE
selection, the SEND impedance is set by the left TX/2W key. (Refer to sub-sections 5.2.1
through 5.2.7 and 5.3 for more details)
The DIAL selection (sub-section 5.2.5) will disconnect the signal generator function and
permit the operator to substitute a handset for dialing a remote number, talking, or
listening. DIAL may also be used to provide an"Open" function (sub-section 9.7).
SEND functions are displayed by pressing the DISPLAY key so that the SEND indicator
is lighted (sub-section 3.3.9).
The loudspeaker is connected to the SEND functions when the MONITOR switch is in
the TX position (sub-sections 3.3.7 and 3.3.8).
The left SEND key is a toggle on/off selection of one of the functions above it (sub-
sections 9.1 through 9.4).
The middle SEND key toggles on/off the Signalling Frequency lockout (SF SKIP) to
prevent transmission of frequencies in the SF SKIP range (sub-section 9.5) by any of the
left key functions.
The right SEND key selects or sends four fixed frequencies that are set by default to the
frequencies labelled on the panel. These frequencies may be changed (sub-section 9.6).
