TFM-550 Installation & Operating Instructions TiL 99RE262 Rev A Issue 8

f) REMOTE BS - Only used when an RC-550 slave control head is attached.
Setting this feature on will give the transmit selection to the
Band Select switch on the RC-550 rather than on the radio. This
is useful when the operator at the RC-550 is using the VHF high
and low bands. Regardless of whether this feature is set to on
or off, the fourth squelch light will light on both units when both
BS switches are set to the same position.
g) SIDETONE - The TX audio circuit becomes active allowing you to adjust the
sidetone level with the VHF volume knob. When the desired
level is reached, press ENTER and this level will be set for both
VHF and UHF bands. The factory setting is 23.
NOTE: The sidetone level must be set every time you go
through the configuration menu since it takes the setting of the
volume knob regardless of whether you set it or not.
