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 –0dBµ

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 –10 dBµ

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 strong-signal environments). From the “(1) Common Rx” section, press [3] to enter this align-

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.
