thesizer unit VS-2.
@) 1200 ALT switch (The optional UT-10 is
required)
This switch is used to activate the Automatic Lock

farmation an this switch.
@3 144 ATT (Attenuator) switch
The incoming receive signal level is attenuated by ap-
proximately 10 dB when this switch is activated.
When the incoming receive signal is very strong, the
signal should be attenuated to prevent distortion of
the signal, thereby stabilizing the receiver perform-
ance. This is easily done by activating the ATT switch.
This control is also useful when a strong signal is near
your desired signal, while some loss will occur to the
desired signal as well as the undesired signal, the use
of the attenuator will sometimes allow you to com-
plete the OSO.
@4 F. LOCK switch
The selected dial frequency and mode are lacked.
Note: Se =
When the F. LOCK switch is on, RIT and MUTE func-
tions are still active.
