•Use the [t] or [u] key to select the "MID" fre-
quency channel in the alignment range.
•Disable any subaudible tone signaling on this
channel, if present.
•Press the [space] key on the computer keyboard
to start alignment. This activates the transmitter,
and injects a 1 kHz test tone.
•Press the [p] or [q] key, as needed, to set the
deviation to the desired value (typically 3.9 ~ 4.2 kHz, or 2.0 ~ 2.3 kHz for “narrow band” channels).
•When the desired deviation level is attained, press [ENTER] to lock in the new value.
-[6] MIC GAIN
This parameter is used to align MIC Gain level. From the "(0) Common Tx" section, press [6] to
activate this alignment sequence.
•Use the [t] or [u] key to select the channel on which
you wish to adjust the MIC Gain.
•Press the [space] key on the computer keyboard
to start alignment. This activates the transmitter,
and injects a subaudible test tone.
•Use the [p] or [q] key to find the desired MIC
Gain level is achieved.
•Press the [ENTER] key on the computer keyboard
to lock in the new MIC Gain level.
-[7] SUB AUDIO DEVIATION
This section adjusts the transmitter’s subaudible tone deviation level. From the "(0) Common Tx"
section, select [7] to enter this alignment sequence.
•After setting the Maximum Deviation in the pre-
vious section, it is now time to align the subaudi-
ble signaling deviation level.
•Use the [t] or [u] key to select the channel on
which you wish to adjust the Subaudible Devia-
tion.
•Press the [space] key on the computer keyboard
to start alignment. This activates the transmitter,
and injects a subaudible test tone.
•Press the [p] or [q] key, as needed, to set the
deviation to the desired value (typically 0.6±0.1 kHz, or 0.4±0.1 kHz for “narrow band” channels).
•When the desired deviation level is attained, press [ENTER] to lock in the new value.
Alignment
(1) Common RX :-[0] TIGHT NOISE SQUELCH
This parameter is used to align the "Tight Noise Squelch" level. From the "(1) Common Rx" sec-
tion, select [0] to enter this alignment sequence.
• Set the signal generator output level to
EMF (0.5 µV).
•Press the [ENTER] key on your computer key- board to set the “Tight” squelch level.
-[1] THRESHOLD NOISE SQUELCH
This parameter is used to align the squelch threshold level. From the “(1) Common Rx” select [1]
to enter this alignment sequence.
•Set the signal generator output level to
EMF (0.16 µV).
•Press the [ENTER] key on your computer key- board to set the squelch “Threshold” level.
-[2] RSSI (RECEIVED SIGNAL STRENGTH INDICATOR)
SQUELCH
This section allows adjustment of the RSSI level. From the “(1) Common Rx” section, press [2] to
enter this alignment sequence.
•Set the signal generator output level to +3.0 dBµ
EMF ( 0.7 µV ).
•Press the [ENTER] key on the computer keyboard
to set the RSSI squelch level.
-[3] TX SAVE
This section allows adjustment of the Tx Save ac-
tivation threshold (reducing the transmitter pow-
er in
ment sequence.
•Set the Signal Generator output level to +15 dBµ
EMF ( 2.8 µV).
•Press the [ENTER] key on the computer keyboard
to lock in the TX Battery Saver threshold level.
