Slot Size in Seconds
This feature enables you to load up to a 75 second message in
MSG1
, should you need a long
recording (progressively fewer slots are available as your message grows in length). When the
memory limit is reached, the red
Rec
LED will stop blinking and the record function will stop
automatically. With a little practice, you can use this protocol to extend your unit's flexibility.
Message Playback
Until you become fully familiar with your Voice Keyer's operation, we suggest practicing with it
disconnected from your transceiver. This will prevent accidental on air interference.
1. Previewing Recorded Messages:
Whenever the
Xmit
button is
Off
(out), you may
select any message (
MSG
)
in memory
and listen to it on the monitor speaker without
transmitting it over the air. Monitor playback level is adjusted via the
Volume
control
on the keyer's front panel.
2. Transmitting Recorded Messages:
Whenever the
Xmit
button is
On
(in), any
message (
MSG
) you select
will
be transmitted over the air.
3. Single Play of a Recorded Message:
To preview or transmit a message one time only, press
the desired
MSG
switch
briefly
and release.
4. Endless Loop Playback of a Recorded Message:
To preview or transmit a message in
endless loop mode,
press and hold the desired MSG button for two seconds--
until the green
Play
LED begins blinking. When you release the
MSG
button, the first playback will start. It
will then repeat at the interval set by the
Repeat Delay
controls until halted.
5. Adjusting the Endless Loop Delay Interval:
The repeat interval begins at the end of the
recorded message. The front panel knob labeled
Repeat Delay
adjusts the interval from 0.5-
50 seconds in the
X1
switch position and from 5-500 seconds in the
X10
switch position. We
recommend checking the interval time in preview mode (
Xmit
switch
Off)
before putting your
message on air.
6. Halting Playback of a Recorded Message:
Any of the following actions will stop message
playback immediately:
A.
Press the red
Stop
button to halt the message in progress.
B.
Press the PTT switch on your mic to halt the message in progress.
