The volume control for the VEC-254 is located on the front of the unit. To
increase the output volume, push in the power switch to the On position, key the
keyer and turn the knob labeled "Volume" in the clockwise direction. The tone
control is also located on the front of the unit. With the volume at a comfortable
level and the keyer keyed, adjust the tone by varying the knob labeled "Tone".
To use the VEC-254 with the optional external speaker, plug a speaker, with a
3.5mm plug, into the jack labeled "Ext. Speaker". This jack is located on the
back of the unit.
The VEC-254 comes with a trimpot to generate a symmetrical rise time and fall
time of the input signal. This feature eliminates the unwanted key clicks that are
normally heard from keyers. The setting on this trimpot (R20) is made at the
factory and should not be changed.
