Subject: Adjustments for the FT-90R Radio.

Problem: Radio deviation is to hot out of the box, about 7K.
The narrow setting to low.
Fix: The settings are software settable.
Procedure: Enter alignment mode by turning the transceiver off. Short
pins 1 & 6 of the mic jack to pin 4 ground. While pins are shorted turn
on radio. Remove connections keeping the radio on. You are now in the]
alignment mode.
Once in alignment mode press the < or > buttons on the panel to change
the menu settings. These are what you are adjusting.
Each alignment setting is changed by adjusting the "tuning dial"
Once each adjustment is made pressing in on the dial or pushing on the
VFO/Memory button on the mic will lock the setting. This locks the
setting and does not exit out of the alignment mode.
To exit out of the alignment mode press in the DISP/ss button.
Once in alignment mode press the < or > buttons on the panel to change
the settings.
Deviation set by navigating to the MOD menu ( < or > buttons).
Using a service monitor observe the deviation while talking into the
mic, adjust by Turing the tuning dial up or down, set to 4.2K. This
allows for the .6K PL tone when it is turned on. Do not set the
deviation with any tones on ! Save setting by pushing in on the
tuning dial.
You can go onto other setting changes ( < or >) or exit by pressing
the DISP button.
NOTE: PL setting is set by a fixed resistor inside the radio and it
is a SMD part. Just incase anyone wants to change it. Get a service
manual and good luck.
KNOW WHAT YOU ARE CHANGING AND WRITE THE FACTORY SETTINGS
DOWN BEFORE YOU CHANGE ANY OF THESE. IN DOUBT LET THEM ALONE !
